marcus_leonard Posted August 4, 2001 Share Posted August 4, 2001 Having used a medium format Pentax67 for a couple of years I want to upgrade to a 4x5. My photography demands no or little tilt or swing. I photograph outdoors, roadsides and the like, my focusing distance almost always between 20m and infinity, with a normal lens (150mm in 4X5). Sharpness, detail, is the issue here. I have asked my printer who knows my demands pretty well, he argues in favor of a monorail, inparticular some Arca Swiss, with a shortened rail. I had been thinking of a Toyo45AX (I always shoot "horizontally", never vertical and need no revolving back), my printer has his doubts about the mechanics of the Toya45AX and the ramifications for the SHARPNESS FROM EDGE TO EDGE. I am reluctant towards a monorail, but if it gives better results there is no choice. Can anybody help me out here? I would appreciate it tremendously. Thanks. Oh, sure, the lens is of course part of the story, I am inclined to buy a Rodenstock Apo Sironar S 150mm. Link to comment Share on other sites More sharing options...
pat_krentz Posted August 4, 2001 Share Posted August 4, 2001 If sharpness is the story, the lens is the whole story, the type of camera it sets on has nothing to do with the sharpness of the image, but field camera's are a lot more steady in the field than monorails. Why not get a 210mm that will allow for some movements and with 17 inches of bellows you can get 1:1 if you wish. Pat Link to comment Share on other sites More sharing options...
michael_mahoney1 Posted August 4, 2001 Share Posted August 4, 2001 As long as the camera is not moving about after you've focused, the lens and film holder would probably have more impact on sharpness than the camera body. Link to comment Share on other sites More sharing options...

brian_ellis3 Posted August 4, 2001 Share Posted August 4, 2001 What size print do you typically have made? I use both the Pentax 67 and 4x5 with modern (APO Symmar, Super Angulon, G Claron, and Nikon M lenses). My prints with 4x5 negatives are usually indistinguishable from those made with 6x7 negatives, with 8x10 and 11x14 prints. If you don't anticipate using movements, and it sounds like you don't, and if you don't develop your own negatives, I'm not at all sure a move to 4x5 is going to do you much good unless your prints are typically 16x20 or larger. But, if you still want to go to 4x5, I agree with the person who said the type of camera (monorail vs. field) is of no significance at all in terms of sharpness and detail. Assuming a good tripod, a quality lens, and a good camera, both designs will produce equally sharp and detailed negatives. Link to comment Share on other sites More sharing options...
jim_billups1 Posted August 5, 2001 Share Posted August 5, 2001 Marcus, <p> I have been using the Toyo 45AX for almost 3 years now, and am quite pleased with the performance. I also use the Rodenstock Apo Sironar S 150mm as well as Toyo film holders exclusively. lack of Edge to edge sharpness has never presented it's self. As others have posted above, sharpness is not limited to particular brands or types of cameras. There are many factors that can affect overall sharpness.

glenn_kroeger Posted August 5, 2001 Share Posted August 5, 2001 Marcus: I have used both an Arca-Swiss 45FC and a Toyo 45AX extensively. The only situation in which the Arca-Swiss MIGHT produce a slightly sharper image is with a lens >300mm in focal length where the rigidity of the Arca is somewhat better. The Toyo mechanically excellent but somewhat more flexible at its maximum extension which is needed to focus a non-telephoto 300mm lens. For a 150-210mm lens, both cameras will produce equal results if used correctly. I would have to agree with Brian, that if you use no tilt or movements, you won't see any improvement in the image unless you enlarge to more than 16x20, and you will sacrifice some depth of field.

ellis_vener_photography Posted August 5, 2001 Share Posted August 5, 2001 Going from one format to another isn't really an upgrade in the sense that I think you mean it. I cannot imagine that any 4x5 camera really is going to fit your needs. A modern roll film SLR is going to hold film flatter than any large format holder will and you'll have more precise alignment between groundglass and film plane location as well. if you are looking for a camera that will give you some basic movements like shift or rise fall as wel las tilt than you should consider the Fuji GX 680III instead. <P>Changing formats from a roll film SLR to a view camera is more like a change in photographic philosophy.

bill_glickman Posted August 5, 2001 Share Posted August 5, 2001 Marcus, if you do attempt 4x5 and are choosing between the field and monorail type...I can add only one thing.... I shoot with the Toyo 45AII and the Toyo VX125. The VX125 having a telescopic monorail makes the set up and break down process way way faster. If you shoot a lot, this sure is a nice feature...but you pay for it in camera size. I agree with the above posters...put your money in the sharpest lenses and the best film holders you can afford.... Link to comment Share on other sites More sharing options...
paul_owen Posted August 5, 2001 Share Posted August 5, 2001 Marcus, I'd stick with your current set-up. As long as it does the job why change? Changing to LF is not about "upgrading". As previous postings have already mentioned, your medium format kit is "technologically" way ahead of most LF. Using a view camera involves a change in the whole process of making pictures. I'm not sure what medium you use (colour or black and white) but a move to LF demands some control over processing and printing. The Pentax has an excellent reputation, stick with it!!

armin_seeholzer Posted August 5, 2001 Share Posted August 5, 2001 Hi Marcus <p> I agree with the most former posters but not with the idea thad you need a monorail if you start with 4x5 it will be the best a Linhof Technika or the Horseman FA for your use and demand!And for the lens the Rodenstock Apo Sironar N is a little bit sharper then the S version and it is also not so heavy! And for your little movements very okay.But if the sharpness is your goal you need the Schneider Vacuum Back too, so you get everything out of the lens!Good luck!

bob_salomon3 Posted August 5, 2001 Share Posted August 5, 2001 " And for the lens the Rodenstock Apo Sironar N is a little bit sharper then the S version" <p> Afraid you have your facts backwards <p> The S is the superior version Link to comment Share on other sites More sharing options...
armin_seeholzer Posted August 5, 2001 Share Posted August 5, 2001 Hi Bob <p> I was quiet sure to get a response from you regarding my stating. I did a testing for my self 4-5 years ago S version against the N version, and the N version was the winner in sharpness, but only visible in really uge 30x times enlarments. So it was head on head with a very little pluspoint for the N!And I spoke to a men from germany, he came to the same results!But If I would need much shift and tilts I would take the S version without any doubts!

bob_salomon3 Posted August 5, 2001 Share Posted August 5, 2001 Sorry Armin but I question your testing. <p> How many of each lens? <p> What conditions?What image ranges? <p> The S will win 9+ times out of 10 Link to comment Share on other sites More sharing options...
doug_paramore Posted August 5, 2001 Share Posted August 5, 2001 Brian Ellis brought up one really important part of LF sharpness: The use of a good tripod. Get one twice as sturdy and heavy as you think you need. As for sharpness, any modern, well designed camera coupled with the Sironar lens will produce excellent sharpness. My preference for the shooting conditions you describe would be for a field or technical camera. You also need a good loupe. One other point... once you start using a LF camera, you may find that you will use the swings and tilts more than you think at this point. Good luck with your quest. <p> Regards, Link to comment Share on other sites More sharing options...
david_rose3 Posted August 5, 2001 Share Posted August 5, 2001 A Crown Graphic would be perfect for the work you describe. The main limitation of the Crown is a non-rotating back, but if you want only horizontal format images, it's perfect. It also has the advantage of being cheap, so you won't loose to much if you decide LF doesn't work for you, or if you want to try a different camera once you get a feel for things LF. Put your money into the lens. Link to comment Share on other sites More sharing options...
jeff_taugner2 Posted August 5, 2001 Share Posted August 5, 2001 Armin, Just so you know, Schneider is no longer making Vacuum back. They had too many problems with the material it was made from with static electricity. Link to comment Share on other sites More sharing options...
wilhelm Posted August 5, 2001 Share Posted August 5, 2001 I agree about the Crown Graphic. I also agree that you're not gonna notice any improvement from the 6x7 on a tripod until you get to 8x10 contact prints. Link to comment Share on other sites More sharing options...
bruce_m._herman1 Posted August 5, 2001 Share Posted August 5, 2001 Marcus, <p> If you live near a gallery that has Robert Glenn Ketchum's photographs, you could see some very sizable enlargements of images made with a Pentax 6x7. I haven't heard anyone complain about his technique. <p> One significant advantage the 6x7 as over the 4x5 is ease of setup. I know of at least one professional who moved up to 4x5 for landscape photography and then moved back when he saw how frequently he lost the light before he could trip the shutter. <p> Having said all of that, I moved from 35 directly to 4x5 and will stay where I am because I make extensive use of tilt and rise/fall. I think that once you move to 4x5, you may find your horizons expand if you explore the movements that are available. <p> Bruce Link to comment Share on other sites More sharing options...
armin_seeholzer Posted August 5, 2001 Share Posted August 5, 2001 Hi Bob <p> Just to answer your question. To be honestly I tested only one S against one N and thad N I still use and I don`t give it away! But what is with the german gentleman who got the similar results like me, without knowing about bevor? Of course it could be a lucky chance, but as far as I remember he tested more then only one. Mine I tested has been new, at the testing! But anyway it is easier to make a small diameter lens perfect then a larger one you agree on thad, Bob? But as mentioned in my first posting, if I would need the larger image circle from the S then I would take it! Link to comment Share on other sites More sharing options...
bob_salomon3 Posted August 5, 2001 Share Posted August 5, 2001 Armin, The S has measurably and visably better performance, less distortion, better color, better range of optimal apertures, etc. <p> The problem is how did you test them? <p> I haven't seen your answer. <p> And it is possible that you found a truly superior N. But I still question the test first. Link to comment Share on other sites More sharing options...
armin_seeholzer Posted August 5, 2001 Share Posted August 5, 2001 Hi Bob <p> I forgott the image range! The testing where 2 and 4 meters distance, my almost working distance in my little studio. But if I take it out for longer distances at infinity I`m always happy with the results, if it was a clear day! But the testing was only 2 and 4 meters without shift and tilt!

marcus_leonard Posted August 5, 2001 Author Share Posted August 5, 2001 To everyone who wrote an answer to my question: <p> Thank you all very much, it is really wonderful to find so many responses, after just one day! <p> The reason for calling a 67 to 45 move an upgrade is that I really want to make large (color) prints, 30X40 (inches) or larger. With my 67 I shoot in a very slow way, always using a tripod, being economic with film. In fact, in that respect I seem to use my 67 as a mini 45. So the philosophy, also my attention for the image composition, seems to me not that different, I did consider this issue. The point about the lesser degree of film leveling in a LF is well taken. However, the tripling of the number of grains is the decisive factor, provided optics and mechanics will not negate this benefit. Film holding will to some degree, I worried about the mechanics and wondered about mono versus field. Your answers seem to tell me not to worry about that issue. Right?

ellis_vener_photography Posted August 5, 2001 Share Posted August 5, 2001 I've had no problem having 40"x40" prints made from 6cm x 6cm Hasselblad camera/Zeiss lenses) negatives and transparencies, or 24"x 30" prints made from 6x7cm film (Pentax 67 bodies and lenses. Detail is rendered with extraordinary crispness with architectural subjects. I am using mirror lockup w/ cable releases, a good tripod (gitzo 410) and Arca-Swiss B1 and B2 Monoball heads.<P> whether you decide to go with a monorail or a folding field camera design is sort of a personal preference. A high quality monorail camera -- Arca-Swiss F series, Linhof Technikardan TK45s, a Sinar P, C or X series --is every bit as stable and possibly quite possibly even more stable and as "solid" for field work as any field camera , and while they have thhey have the benefit of more extensive movements, they are also much bulkier (except in the case of the TK45s or the Arca FC cameras).<P> Bluntly: while right now you are insisting that you don't have any need for movements, but my guess is that as soon as you get a camera that has movements you'll start using them, especially vertical & horizontal shift, if for no other reason than the greater control you'll be able to exercise over your composition. Rear swing and tilt will offer you a great deal of perspective rendering control that a rigid bodied SLR cannot.<P>You should also consider where the nature of custom printing is technologically heading, and that is towards the universalization of some sort of digital intermediate step for large print making. Labs that can produce a better print directly from a piece of film than they can from a scanned piece of film (with the print generated either directly from the scan or (ala' Andreas Gursky) from a digitally generated internegative or interpositive will become increasingly hard to find over the next few years.

william_marderness3 Posted August 7, 2001 Share Posted August 7, 2001 I once used the Pentax 6x7 before switching to 4x5 and then to 8x10.With 16x20 prints made from 400-speed color negative film, I couldtell a difference between 6x7 and 4x5. As close distances (within 12inches of the print), the prints from 6x7 negatives showed grain. Theprints from 4x5 show no grain, even with a loupe. 8x10 contact printsshow an improvement over 4x5, but enlargements from 8x10 do not.<p>If you want to make very large prints, the 4x5 may be right for you. Ihave both monorail and field cameras, and my field camera is morestable than the monorail, so the field camera should give sharperresults in the field (if there is wind). The stability of the camera(not mono vs. field) can make a sharpness difference. I bet you willuse some movements once you have them. For landscapses, front tiltallows you to get the land in focus from 1 inch to infinity, and frontrise will allow you to look up at trees without having them leanbackwards. I often use front tilt/rise outdoors. Link to comment Share on other sites More sharing options...
