    Bracketing on Pentax 67ii

    in Medium Format

    Posted

    <p>Hi all,<br /><br />I just took delivery of a Pentax 67ii body and am looking forward to going out and shooting with it. I do have a question though which hopefully someone here can help with. <br /><br />I am in the habit of bracketing my exposures usually by 1/3 of a stop up and down. Previously with my Pentax 67i body I had to alter the aperture by the smallest 'click' on the lens (hopefully 1/3 or 1/2 stop) to get the appropriate bracketed exposure. This was because the shutter speed dial could only be adjusted by whole stops. <br /><br />I see now with the Pentax 67ii there is an Exposure Compensation dial which has 1/3 stop measurements. Am I right in thinking now that in order to bracket effectively I can do the following:<br /><br />1) Take original shot as indicated by lightmeter<br />2) Use the Exposure compensation dial to move up to +1/3 (one click) and take the bracketed (longer shutter speed) <br />3) Use the Exposure compensation dial to move down to -1/3 (one click) and take the bracketed (shorter shutter speed) <br /><br />If so, does that mean that even though I myself cannot manually change the shutter speed by 1/3 stop on the shutter speed dial that the camera will work out the exact length of time needed to alter by 1/3 stop and adjust accordingly? I see that when I use the Exp. Compensation dial that on Aperture Priority mode the shutter speed in the viewfinder is changed to speeds which are not options on the Shutter Speed dial (eg, 1/6 second). <br /><br />Thanks in advance for any help,<br /><br />Rgds<br />Rick</p>

    Thanks Dan. Certainly i can use the histogram and a 'trial and error approach' on my D70

    but don't forget that my main usage is on film so some sort of reasonably accurate

    metering technique will be required... Anyway i've just shot a couple rolls today through

    the F6 so i'll let everyone know how they come out wuth samples if any are good enough.

     

    Thanks again,

    <p>Thanks for the new responses.</p>

    <p>Shun, I agree in that I wouldn't normally follow Ken Rockwell's advice very closely but it does seem he has written a reasonable amount about this lens, it's compatibility and general tilt/shift methods... Usually I will look for verification from at least 2 sources before I 'believe' something on the net...</p>

    <p>Dan, yes, of course. I completely forgot (although knew about) the ability to correct converging verticals with this lens! Thanks for pointing that out together with the detailed method of near-to-far sharpness maximising... Like I mentioned earlier I think I will leave the lens unmodified for now and see whether I hit a 'hmmm, I wish I could do that' moment the next few times I go out shooting.</p>

    <p>As for metering, I've read around on manual metering and it looks like all I need to do is choose a relevant aperture (I've read that f11-f16 is optimal for this lens) and then adjust the shutter speed until the light meter zeroes (no over or under exposure displayed). All this while having no exposure compensation set of course.</p>

    <p>Rgds<br>

    <p>Thanks Ilkka. Actually I was referring to using the Program (Shift) mode in the 'zero shift/tilt' position by setting the appropriate aperture setting on the lens and then getting the shutter speed from the LCD readout.</p>

    <p>Can you explain what you mean by "select the shutter speed and aperture as you would normally in manual mode"?</p>

    <p>I'd really appreciate if you could check it out on the F5. I think it would help you to see what I mean....</p>

    <p>Thanks again, Rick</p>

    <p>Thanks for clearing that up regarding the tilt/shift/swing on the same or different axis. I think I will do as Ilkka says and use it for a while like it is before I figure out whether it is worth modifying.</p>

    <p>I've been playing around with the lens a bit today and I have another question regarding getting correct exposure settings. As I am using this on a Nikon F6 Film Camera right now I would like to try and minimize any exposure errors (as obviously these are harder to detect than on a dSLR). So as per Ken Rockwell I set the camera mode to 'Program (Shift)' and then set the aperture manually on the lens using the ring. The F6 then gives me a shutter speed. It seems by moving the aperture ring it does change the shutter speed by what seems a correct amount. All this is being done while the lens is in 'Normal' mode (ie, I have not pressed the aperture stop-down button). If I need to check or re-check focussing I do use the aperture stop-down button to do this.</p>

    <p>Would this be the correct way of getting the exposure on this camera/lens combination? Just wanted to check before I put some rolls of film through it... Also would this work on my older dSLR (Nikon D70)?</p>

    <p>Thanks again,<br>

    <p>Thanks for all your help everyone. One other question I have is that I have read it is advisable to get a Nikon Service Centre to make some adjustments so that tilt and shift are available at the same time? Ken Rockwell mentions,</p>

    <p>"If you're a landscape photographer like me, be sure to send your 24mm PC in to Nikon service before you shoot to have the lens recombobulated by 90 degrees so you can get rise/fall and tilt at the same time. As shipped, you get swing, not tilt, with rise/fall."<br>

    <br />Is it worth doing this? or is swing with rise/fall (shift) sufficient for most purposes? After all if tilt with shift is more useful why would Nikon not make this the default?</p>

    <p>Thanks again,<br>

    Thanks Jose. I will certainly take a look at those 2 books. I'm sure

    the general principles are the same. It would be really handy though

    if someone had written something specifically for these Nikon PC-E

    lenses just so i know how to apply the principles with the equipment

    at hand. Let me know if anyone has come across anything like this.

    <p>Hi all,<br>

    I've just bought a Nikon 24mm f3.5 PC-E lens for usage for my landscape, travel and architectural photography. Based on all the reviews I read it seemed like a good (although expensive) choice for the type of images I am interested in shooting. Now although my plan in the future is to use it in on a pro dSLR body (like the other millions I am waiting for the D700 replacement), for now I am planning to use the lens on my F6 film body. From my reading it seems that the restrictions on tilt/shift/rotation are not too sever on this body...<br>

    Anyhow, I had a thorough read of the instruction manual that came with the lens and it doesn't seem like there is a lot of guidance on the actual step by step usage of the lens. There is a quick 1-2 page guide on shooting but I guess I am looking for something a bit more practical/in-the-field in terms of a tutorial/guide on how to get the best out of this lens.<br>

    From my understanding this lens could be used for a number of applications:<br>

    1) Maximising depth of field (for say landscapes) by using the tilt<br>

    2) Stitching panormas by using a pure vertical/horizontal shift<br>

    3) Special effect type shots which have a very shallow depth of field rendering a sort of 'toytown' look</p>

    <p>Would anyone know of any good reference material on ideally the usage of this lens for these (and other) applications or any generally good reading for tilt/shift lens usage?<br>

    Thanks in advance,<br>

    Any used MF retailers left in Hong Kong?

    <p>There's also a place called Matsuya in a covered shopping parade on Nathan Road (near exit C of TST MTR station)... You can google for the exact address. They have a pretty good selection of MF gear incl. Pentax, Mamiya, Hasselbads and Bronica. I picked up a Pentax 67 and couple of lenses there fairly recently. There's a guy who works there called Robert who is very helpful and can give good advice. Certainly a lot more helpful than most of the guys in Champagne Court (small 2nd hand camera mall on Kimberly road). You can have a loot at Champ. Court but I found the service to be not quite as good and if you look anything like a tourist you may get fleeced....<br>

    Pentax 67 to Nikon adaptor

    in Medium Format

    Posted

    <p>Hi all,<br>

    Popped by my local 2nd hand camera shop last weekend and was told about a new Pentax 67 lens to Nikon body adaptor. Just wondered if and what kind of effect this would produce and whether anyone had used one? Seems to be made in China... Obviously I would not want to attach anything to my Nikon cameras or Pentax lenses which might damage them...</p>

    <p>Thanks in advance,<br>

    Sharpest aperture for Pentax SMC 55mm/f4

    in Medium Format

    Posted

    <p>Thanks Mike. Do you find that f11 is usually sufficient to get enough Depth of Field in your shots. For the landscapes I'm currently shooting on 35mm (with Nikon) which I hope to move to the Pentax I was slightly concerned that for some of those shots f11 may not be sufficient to get enough '3D' effect into the image... I guess I can try these at f16 and hope to a good compromise between sharpness and depth-ality (I just made up that word :-)</p>

    <p>Rgds<br>

    Sharpest aperture for Pentax SMC 55mm/f4

    in Medium Format

    Posted

    <p>Hi all,</p>

    <p>I've just 'invested' in a Pentax 67 together with a 55mm/f4 lens. I believe the lens is the last generation as it takes a 77mm filter and also states Pentax SMC 67 rather than 6x7 which I understand can be used to differentiate the versions.</p>

    <p>I'm sure this question may have been asked before but are there any comprehensive ratings/test websites on the qualities of this and other lenses which show the proven sharpest apertures ? If not can other owners of this lens suggest from experience what they believe the sharpest aperture(s) is/are ?</p>

    <p>I've seen some comments that mention f11 as being the sharpest but others which say that the lens is sharp all the way through to f22 ?</p>

    <p>Any advice appreciated,</p>

    <p>Rgds<br>

    How to lighten/improve P67 Dark Viewfinder/Focussing Screen ?

    in Medium Format

    Posted

    <p>Thanks Robert. Maybe that's the problem. I'm probably trying to make too many comparisons indoors and not enough time going out shooting... With landscapes I would assume that using infinity or hyperfocal focussing probably would make the viewfinder slightly less important anyhow... (I have started a seperate forum thread on optimal focussing for sharpness using the P67)...<br>

    <br /> Thanks<br>

    How to lighten/improve P67 Dark Viewfinder/Focussing Screen ?

    in Medium Format

    Posted

    <p>Thanks for the advice Robert but actually I just bought the 67. At the time of purchase I had the choice between the 6x7, 67 and 67ii. I wanted MLU but didn't necessarily want to pay the premium for the 67ii (which was almost double the cost of the 67) hence I chose the 67. For the most part I don't think there are any major features which I'm missing but it would be easier if that focussing screen was a touch brighter....</p>
