shawngibson Posted September 25, 2000 Share Posted September 25, 2000 I've been studying the whole M line in order to figure out which is best for me, (I want to shoot with ONLY a 75mm lens--probably the Voightlander to start--and from what I can tell, I want the M4-P for the 75mm framelines, but with the M3's 'higher-magnification' finder...which is my question, I guess: can I do that..change the M4-P's finder to the M3's and still have the 75mm framelines). Some some of the things I keep coming across are the following (from cameraquest) and I don't really understand the basics of finders/baselines/magnification/etc...the 'rangerfinder' part of rangefinders: <p> >>"M3: Much longer and therefore more accurate rangefinder <p> >>"If you like to shoot the 50/1 Noctilux or the 75/1.4 Summilux, M3's focus them more accurately than any other M with the longest effective rangefinder base length and focusing accuracy in the M series. M3's can focus 25% MORE ACCURATELY than the M4/M5/M4-2/M4-P and M6 due to longer effective baselength rangefinder <p> >>"M4-P: The M4-P [adds] a six position finder for 28/35/50/75/90/135 lenses. <p> As I say, I want to shoot with a 75mm as my standard and only lens. Somewhere on the cameraquest site, I've read that you can change the finders between M cameras. <p> I don't want to use an auxilliary attachment to see the 75mm focal length (it seems a real pain...especially for my only lens), and so what I want is the best 75mm set-up I can get on a non-collecor (read: affordable) M camera. <p> Am I thinking correctly? M4-P + M3 finder? or am I not quite understanding how this all works yet? <p> Thanks sincerely, shawn Link to comment Share on other sites More sharing options...
robin_smith Posted September 25, 2000 Share Posted September 25, 2000 Shawn <p> The only official changes I know of is that the original M4 and M4-2 can be updated by Leica to have the M4P/M6 frames. I do not think you can convert the M4P to be equivalent to the M3 - or I am not sure it would be easy. Someone might be able to black out your 50mm framelines so that all you saw was the 75mm, which would seem more straightforward. Not that this would help with the focussing accuracy issue. <p> What you really want perhaps is someone to add the 75mm framelines to an M3. Or you could get a .85 M6 to get near-M3 accuracy.

jason_gold1 Posted September 25, 2000 Share Posted September 25, 2000 I can see no merit in a 75mm NON Leica lens of very ordinary aperture,f2.5 being made as main lens.I think you would be better with a 50mm Summicron and slight crop.I frame with 90mm frame for portraits BUT use the 50mmm !I have a much sharper lens,wide aperture if needed and a wider angle than 75/90,if used normally.You can add M6 frames to M2/4 NOT the M3.Again we see the "slr idea" of fitting any lens to a Leica RNGFDR.One of the best photographs I`ve ever taken was using this method at a political demonstration.The 75mm Summilux is a special lens offering TWO more apertures than the V-lens.....

shawngibson Posted September 25, 2000 Author Share Posted September 25, 2000 Thanks so far. Jason, I understand the non-Leica lens issue (why buy a Leica, right?); but I want to shoot the 75 f1.4, don't worry. I am going to get the Voightlander til I can afford the Leica (a tremendous difference in price, and no doubt, performance), that's all. <p> It sounds, so far, like the best answer is to have 75mm frame put into an M3?

john_collier Posted September 25, 2000 Share Posted September 25, 2000 If you have enough money, you can do anything, however, as you are starting with the Cosina/Voigtlander lens because of budget constraints, this indicates that it is unlikely you can afford very much custom work. I have friends with a M3 finder in a M6, retaining full meter function, M4-2s with M3 finders and M4s with the 0.85x finder. To install an M3 finder in a later camera is expensive as you need a donor camera with a good finder and the body will require a significant amount of precision machining. Also to put a 75mm frame in a M3 would be very expensive as well as it would have to be custom made. After all this bad news, here is what I would recommend. Buy a M4-P and the Cosina lens, then use them until you can afford the 75/1.4. After that you can have the M4-P finder replaced, completely, with a 0.85x finder if you feel that is necessary. The standard 0.72x finder is fine for focusing the 75/1.4. The cost of changing finders is about $700US to $900US. Link to comment Share on other sites More sharing options...

This is pretty much what I've been thinking as for 'price/purchasing' ability. Not many people think like I do in regards to buying (piecemeal/moving up slowly). Thanks for the probably-unintentional vote of confidence. <p> As for the .85, I guess this is theoretical meanering on my part, and you are probably right, I may do fine without it. <p> I am probably going to forego the Toronto scene (from what I've seen and heard, it's not that great for Leica), since I have to get Voightlander through the US anyways, and I'll keep my eyes open on EBay for a M4-P. <p> Thanks a lot for all your help.

albert_smith Posted September 25, 2000 Share Posted September 25, 2000 Shawn, <p> I am not saying that the M3 can't be modified, but every book that I have on Leica Ms states just the opposite. They say any M series camera EXCEPT the M3 can be modified to the M4P / M6 finder. The M2 has a bit of a higher magnification in its original form, but the housing will accept the modification. <p> Essentially, the frame is simply etched onto a screen that projects an illuminated line into the viewfinder path... for the lens attached. In theory, (and that is a big "in theory"), 75mm frame lines could be added, but it would be a scary proposition to possibly ruin a great camera. I couldn't imagine being drunk enough to even think of attempting to have this surgery performed. It would be a total freelance type of thing... Lieca won't do it. <p> If you are married to the 75mm lens as you primary lens, I would get a new .85 M6. The M3 has a .91 magnification... in the real world, you would not suffer much focusing in accuracy. Tony uses his f1 Noctilux on a classic M6, and his shots look great wide open. <p> I do agree that the use of the Voigtlander 75mm lens is acceptable until you can save up for the Summilux. They are different, but not so much that the Voigtlander is poor... it is just that the Leica is so good. Many hardcore Leica users in the LUG have embraced the Voigtlander... and are admonishing Lieca to bring out a mid level lens of a similar spec. <p> This might be too techno' to read through, but I am attaching a web site in which Leica Guru, Erwin Puts has investigated the accuracy of rangefinders... including the new .58, and shows the maximum allowable f-stop for specific focal lengths. In a few words, any leica camera can focus the 75 f1.4 accurately... now the frame may be too small on some models, but they will focus no problem. <p> http://www.imx.nl/photosite/leica/technics/rfaccuracy.html Link to comment Share on other sites More sharing options...
shawngibson Posted September 25, 2000 Author Share Posted September 25, 2000 Thanks Al. <p> I printed that page off. Your comments were very helpful, especially "In a few words, any leica camera can focus the 75 f1.4 accurately... now the frame may be too small on some models, but they will focus no problem". <p> ...I guess what you're saying is, the focus is physically accurate, but just occuring over such a small region of the frame to make it difficult for the human eye to 'see' if it is or isn't truly in focus. <p> I agree that the 'perfect' camera is probably the M6, with the framelines for 75mm, and the .85 magnification (I don't yet understand how the lens's aperture determines anything on a rangefinder, except maybe, after what you've said, for giving a brighter--and therefore more easily seen--image in the viewfinder. <p> However That would mean I have to wait until December before I can buy. I don't know 'bout that!!! Link to comment Share on other sites More sharing options...
robin_smith Posted September 25, 2000 Share Posted September 25, 2000 Shawn <p> What Al means is that the frame for the 75mm is small in the viewfinder. The wideangles subtend a larger angle so are larger. It has no affect on the rangefinder spot size, but a smaller frame size makes it harder to visualize the final result. Kind of like seeing the shot through the wrong end of telescope versus on a movie screen. <p> Look through any M and you will understand. Link to comment Share on other sites More sharing options...
shawngibson Posted September 25, 2000 Author Share Posted September 25, 2000 Yah, that's kinda what I was **trying** to say. Pardon my words. I know the rangefinder image is constant, and that the 75mm line will be quite small, especially on a finder that goes from 28-135; not actually having looked through an M4-P (only an M4 and various fixed- lens RFs), I imagine the 75 will take up fairly less than half the viewfinder? ...So trying to line up verticals/horizontals in that small area is **probably** going to be like using the 'rangefinder' on a nikon SLR...that little useless split-circle...?

albert_smith Posted September 25, 2000 Share Posted September 25, 2000 Shawn, <p> As far as the importance of the f-stop regarding the focusing ability / accuracy... It is related to the lens' depth of field. Take for example the 50mm lenses for the M Leica. There is a f2.8 and an f1.0. The combination of the viewfinder magnification and the rangefinder base determines the accuracy... However, you can be a bit sloppy when focusing the f2.8 lens, but you need to be absolutely critical for the f1.0. In other word, the extended depth of field of the slower lens will allow some deviation before the lens is considered "out of focus". <p> The opposite is true as you start getting into wide angle lenses. An SLR is harder to focus a 21mm lens than when using the rangefinder, because the extreme DOF of the wide-angle makes it harder for you eye to determine IN FOCUS / OUT OF FOCUS... it is a judgment, but the RF camera takes none of that in consideration. The 21 and the 90 focus with the same ease. Even using that split image in the SLR is sort of a rangefinder... but with a tiny base. I've seen an in-writing test saying that for a 50mm lens, the RF is 6 times more accurate than the SLR. Since none of us have a problem focusing an SLR with a fifty, you can imagine the rangefinder is pretty good... good enough for an f1.0 lens.

cing_dao_kan1 Posted September 25, 2000 Share Posted September 25, 2000 Depending upon what you using the 75 Summilux for, you may consider use the Voightlander 75mm viewfinder on a M3. It is, of course, not an ideal combination but may help for both focus and frame accuracy. I have been using the combination of M5 (with 75 frame line added) and 75 Summilux and I am very satisfied with it. The majority of shoots with 75 Summilux are open f-stops. I don't really feel 0.72 finder compromises the focus accuracy for using 75 Summilux wide open. <p> BTW, putting 75mm frame line in the M3 is not very practical at all. Not many experienced Leica repair specialists would want to do it even if cost is an objective. <p> Cing-Dao Kan Link to comment Share on other sites More sharing options...
andrew_schank Posted September 25, 2000 Share Posted September 25, 2000 "; not actually having looked through an M4-P" Shawn, I'm going to offer a bit of advise that may save you a lot of trouble that I went through. Go to a used camera show or find a nearby large store that carries a good selection of used Leica cameras, and get your hands on a some of this stuff in person. Put a 75mm lens on the camera and see if that is really what you want to hang on your neck. I made the mistake of reading all kinds of stuff at Cameraquest and other sites, and figured out theoretically the perfect camera for me. I bought an M6HM TTL with 35mm aspherical Summicron for a huge chunk of change mail order without ever even holding one in my hands (I am an M3 shooter). When the camera arrived, to my surprise, I hated it. I hated the finder with all the lines in my face. The range finder patch was whiteing out on me. I didn't like the cheesy winding feel (compared to the M3), I couldn't hardly see the 35mm lines, etc. Don't get me wrong, for what it is ,the M6 HM TTL is an exceptional camera, but in my mind, I had convinced myself without ever seeing one it was going to be an M3 with a built in meter. IT ISN"T! Luckily I sold the stuff on e-bay for about what I paid for it, but it taught me to get my hands on the stuff I'm interested in instead of spending too much time reading and talking about it.

shawngibson Posted September 27, 2000 Author Share Posted September 27, 2000 Andrew I took your advice and went all over the place last night, 'feeling' Liecas. I could not find an M4-P, but I played with an M6 .72, an M4 'Midland" (or something like that); an M3 (very briefly), and a CL. <p> I found all the Ms to be very similar in 'body feel' to my old F3. They were awkward. But the viewfinder in the M6 was marvelous. I could live with the 75mm framelines on that, no problem. But I also, as I say, tried the CL. It was a beater, something I would never buy. And I've heard things which 'in theory' should leave me put off of them compared to a true M, or even a Voightlander for that matter. <p> But I loved the feel of the CL. It felt...made for me. This worries me. I keep seeing myself buying this camera on EBay and trying to put the Vgtldr. Color Heliar on it. And staying stopped down and using small Metz on it when necessary, shooting at 3200EI otherwise in low light. <p> Does that sound feasible? <p> Also, do Leica Ms grow on you, or do you love them or hate them from the get go?

shawngibson Posted September 27, 2000 Author Share Posted September 27, 2000 ps the 'Voigtlander double accessory shoe', apparently, 'has no hot shoe'. Does this mean I can't put the 75mm finder and a flash on a CL at the same time (or any other camera for that matter)? <p> Sorry for all these q's in one post, but I don't wanna clog up the dbase with too much info during these primative times...:-) Link to comment Share on other sites More sharing options...
robin_smith Posted September 27, 2000 Share Posted September 27, 2000 Shawn <p> Double accessory shoe - you are correct. It is really designed for their meter + a viewfinder. <p> The CL has a nice viewfinder and it is a great little camera. But, it is also not really an M in terms of construction (much more lightweight). But it does have a Leica-quality viewfinder and of course takes M lenses. I use it with the 40mm Rokkor and a 90 modern Elmarit it makes a wonderful travel camera. The meter is a bit erratic there is no doubt about that, but does work OK - but there again you have to make sure you get one that does - many of the s/h ones need servicing.

shawngibson Posted September 27, 2000 Author Share Posted September 27, 2000 Thanks Robin. <p> Something I've been unable to figure out (and never checked at the store...duh): can I shoot the CL in full manual? I don't HAVE to use the meter, right? Link to comment Share on other sites More sharing options...

albert_smith Posted September 27, 2000 Share Posted September 27, 2000 Shawn, <p> PLEASE READ!!! I hope that my previous answer was not misleading. When I told you that "any Leica can accurately focus the 75mm f1.4"... I meant any Leica M series camera. While the CL has an M mount, it is generally not included in the series. The fastest / longest lens offered for either the CL or the Minolta derivative CLE was a 90mm f4.0. Some users are comfortable with the 90mm f2.8, but I can't even imagine the 75mm f1.4 focusing while wide open at moderately close distances. One of the trade offs for the smaller body is the reduction of the rangefinder base. Remember, there are two parts to RF accuracy, the magnification and the base... reduce either one (or both) and the accuracy goes down. This is not a problem for the normal range of lenses, but the 75mm Summilux is not normal. <p> If you are truly locked in to using this lens.... You need to get a true M camera. I read your responses in this and the "CAMERA EQUIPMENT" thread and it seems like you are serious about the CL. Please understand the limitations regarding the 75mm lens. <p> Sorry for any problems due to my post about rangefinders. Link to comment Share on other sites More sharing options...
shawngibson Posted September 28, 2000 Author Share Posted September 28, 2000 Thanks Al. I am starting to understand, slowly, the virtues and limitations here. I realize (sort of...) that a CL is not going to work practically AT ALL with a 75mm 1.4 wide-open. But I can't buy that lens yet anyways...one just sold on eBay for approx. $2000US, which is simply out of my budget right now. So, I'm going to get the Vgtlndr 2.5 to start. And from the cameraquest site, it says anything from a 50mm f2 to a 90mm f4 should work fine. The 75mm f2.5 seems to fall nicely between those two extremes, so I should be alright until I can afford the Leica glass. <p> As for the CL, I loved the feel of it. The Ms, all of them, reminded me of my F3 in 'feel'. I'm not saying I won't buy an M. I was just saying how nicely the CLs fit. But overall, I did not in the least find them 'unruly'. I'm gonna play around a bit more with both the Ms and the CL. <p> .85-.91 (the M3s .91, right?) seems the best mag. for a 75mm lens. As for a separate 75mm finder, I emailed Stephen Gandy, and he thinks I should just envision witha 90, and wing it. That would open up the shoe for a small Metz as well. <p> See, Al, I'm really not convinced of anything yet. The CL felt really nice, but that is only part of the concern for me. I still wanna look.

robin_smith Posted September 28, 2000 Share Posted September 28, 2000 Shawn <p> At the risk of stating the obvious - have you looked at the Bessa-R. That has a 75mm frame and will work superbly with the v75mm. Of course it is no good for the Summilux, but the R is much cheaper. Somehow unless you are really good at visualising a 75mm frame using the existing 40/50 and 90 frames I think using a CL with a separate 75mm finder might well be a pain. I have a 135 Elmar which I use occasionally with the CL and a separate 135 viewfinder. I like it actually, but it is no good at all for action shots or when you need to be quick.

shawngibson Posted September 28, 2000 Author Share Posted September 28, 2000 Ya, I've thought about that one, too. Cheap, that's for sure, bright from what I've heard, no need for bayonet adaptor with their Color Heliar. Framelines for 75mm. Maybe I'm just being stubborn, but to buy a non-Leica lens, and a non-Leica body--I have no qualms purchasing the Voightlander lens since it will get me started, but I just know that if I were to buy a Bessa/Hexar I would end up getting antsy. OK a snob lurks within, even if he isn't the richest of snobs...But who knows, maybe sanity will kick in sometime!!! Link to comment Share on other sites More sharing options...
shawngibson Posted September 28, 2000 Author Share Posted September 28, 2000 ps It kind of bothers me that I didn't naturally gravitate to the Ms...and that the CL felt so right to me...I am very small framed/small-handed, and maybe that accounts for it, who knows...another reason I am leary of buying the Bessa from the States (they're not sold in Canada...).

albert_smith Posted September 28, 2000 Share Posted September 28, 2000 Shawn, <p> The purchase of an M series Leica is never a casual thing... unless you have way too much money. Take your time and be absolutely certain since mistakes are expensive. I still feel the best advice is to try somehow to borrow or rent a camera, and run at least 10 rolls of film through it. You will either know that this is the camera for you, or that your search continues. Leicas are romanticized in the photographic press, but not everyone gets along with RF cameras. The good thing is, that unlike all of the "wonderplastic" out there, when you've made your decision... the cameras will be there. <p> As far as your lens choice, is it the focal length or the lens speed that has drawn you to the 75mm summilux? If it is the focal length, a 90mm Elmarit M simply can't be beat when you factor in the cost to the performance. They are readily available for under 1000 Dollars. At only 15mm over the 75, you won't notice the difference in most situations. If the speed is your goal, the 50mm Summilux will get you the speed at a more affordable price and smaller package. The difference from the 75mm lens is only a couple of steps forward. Again, there is great savings on the price of this lens over the 75. <p> Just don't be impulsive. With your monetary situation, your move has to be the right one. You also have the benefit of a couple of hundred years of experience in this forum, so don't hesitate to ask for help. Just remember everyone is different, so weigh any advise against your personality and desires. Link to comment Share on other sites More sharing options...

Great advice in all. <p> As for the focal length, I am ASSUMING something grand here: I generally shoot with a standard and a tele lens, but I really want just one lens. And given <i>that</i> choice, since I shoot people and 'like' the telescopic perspective/distance (and the benefits of not cropping-in on a 35-50mm lens), I have been, as I say, assuming the 75 is the best bridge for one lens to a 50-90mm shooter. <p> [90mm lenses (well, to be honest in my case a couple of 85mm lenses, Contax and Nikon), just seem a little long in a lot of indoor situations, especially when you want more than 3/4s of a human body.] <p> However, given the price of a 40mm lens (40 Rokkor esp.), and a 90 (the old 2.8 seems great?), I know it might be better to bite the bullet and go with 2 lenses. <p> But there is a romance to a single 75mm lens that I can't explain away. I wish I could try all this stuff before purchasing, I mean really try it as you say, for a few rolls of film, not just try all these bodies and some 50mm lens I'll never buy...in the store. <p> The 75 might end up being fancy like Keats' Nightingale...and the 40-90 combo might be as timeless as his Urn...the latter is obviously much more practical in real-time shooting...for once I'm not going to be impulsive. Not with a body, and not with my choice of glass... <p> As for the 1.4 of the 75mm Leica, that's pretty much pure romance and material lust...I shoot in bars quite often/in homes as well, but I prefer to use EF in these cases, because I LOVE as much DoF as possible. I've never really like shallow DoF except when explicitly in order for the scene at hand... Link to comment Share on other sites More sharing options...
