    Locked Pentax 67II

    in Pentax

    Posted

    <p>Douglas:<br>

    The 67 can be made to fire without a key by doing the following:<br>

    open the back and advance the racketed wheel in the center of film advance lever until the film counter reads something greater than one. You can accomplish this by pressing down with a fingernail and twisting. It is not easy to do (for me anyway), but I have seen a Pentax repairperson perform this as easily as I open a jar of jam. You should then close the back while keeping the counter at the non zero position. Once the back is closed, you can release the wheel and will be able to cock and fire as much as desired.</p>

    <p>If you don't object to the use of an adapter, there exists a huge number of old manual lenses for potential use. There is a discussion group at Fred Miranda devoted to just such applications. By way of example see:<br>

    A search there will produce more discussions than you will have the time or patience to read.</p>

    Pentax 67II winding issue - needs service? in Europe

    Unless you have a Pentax service center near you, I would recommed contacting Eric Hendrickson at <a href="mailto:pentaxrepairs@aol.com">pentaxrepairs@aol.com</a> . He is in the US, so there would be a high shipping charge, but he stands behind his work and his charges are fair. I have had several items he repaired and he does as well as Pentax. I had the same problem by the way. </p>

    PS CS4 slow in 64-bit-but normal in 32-bit

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>Tired of struggling with big (500 MB) scan files in PS CS3 with my system, I recently purchased a new computer (i7, 12GB RAM, Vista 64-bit, ATI 4850 512MB video card); I also downloaded the trial version of PS CS4. Well I was as happy as can be, what took 5 min. on my previous system now took 20 sec. Then, quite suddenly, I noticed some odd behavior: painting on a mask, I saw the effect appear somewhat delayed and not the area I had painted! Then I noticed a delay in turning layer visibility on and off. Upon clicking on the eyeball, the eyeball remained for a few seconds, then disappeared but no effect on the image, i.e. the layer was still visible unless I used the mouse wheel to resize. There were some other processes slowed as well. Although I was working on a 1.5GB file at the time, smaller files behave in a similar way. I removed and reinstalled the video drivers, the BIOS and CS4, none had an effect. Interestingly, if I launch CS4 in 32 bit mode, it behaves normally, but defeats the purpose of having all that RAM. I checked the Adobe forums and could not find a similar report. Open GL on or off has no effect and the ATI 4850 is listed by Adobe as a tested card.<br /><br />Any advice appreciated.</p>

    <p>You can modify the stock holder to use glass, see:<br>

    <a href="../digital-darkroom-forum/008Jf3">http://www.photo.net/digital-darkroom-forum/008Jf3</a></p>

    <p>Works very well; get the glass from focalpoint, about $20. FWIW I've tested using both anti Newton and clear glass. I see no difference in sharpness or contrast, but the clear glass sometimes has Newton's rings</p>

    Will a 64-bit, 12GB computer help with big tiff files in PS?

    in The Digital Darkroom: Process, Technique & Printing

    <p>Thanks for the replys fellows. You pushed me over the brink, I went to Dell outlet and bought a refurbished XPS 435 with i7 processor, 12GB and 512MB video card for $1000. I was afraid to to sit on a decision for fear it would be gone as it was the only one with 12GB. Of course now I realize that I HAVE to get CS4 to take full advantage of the 12GB and I can't get vista 64 drivers for my monitor calibration device, so I'll need a new one of those. I also can't get 64 bit drivers for my Nikon and Minolta scanners, so I have to keep the XP system running. This is going to end up costing a bit more. I tried all the speed tricks with XP: separate physical drive for scratch disk etc., so I hope this does the job.<br>

    Edward: I scan 6x7 in 16 bit on a Nikon 9000 = 500MB files. I prefer to make overall adjustments in 16 bit to avoid the picket fence in the histogram and then convert to 8 bit to make the file size reasonable.<br>

    Mike: I checked your link. Adobe supports Vista 64 but not XP 64.<br>

    Thanks again guys form me and my credit card company. </p>

    <p>I'm increasing frustrated working on scan files of 500 MB in CS3 with my current computer. I have a dual core with XP and the 3GB switch is on which yields about 3.25 GB of RAM. Many proceedures are very slow (e.g. smart sharpen takes 5 minutes); Bridge likes to crash as well. I could switch to XP 64 bit, but my machine will still be limited to 4GB. I see the new Dells and HPs with quad core, 64-bit and 12GB of RAM and I have to wonder if that will really solve the problems of slowness. Anyone with experience please advise I don't want to invest the money in a new system only to see marginal improvement.</p>

    Switching Systems....Time To Move On

    <p>Justin et al:<br>

    I read this forum as I'm a long time Pentax user (back to the Spotmatic) and I do own a K20D but as I am primarily a film shooter (645 and 67) I don't post here often. You will enjoy the 645, it feels good in the hand and is built like a brick (you could proably use it to pound tent stakes). The 645N is in almost every way an improvement over the original 645. The one advantage the 645 has for trekking is that the grip is easily removable, turning the camera into a small cube which is much easier to pack. Should you decide you like the 645N, consider buying a 645 for a few hundred dollars just for those times pack space is at a premium. The 35mm is a very good lens, in partiular the FA version, but you will have a hard time finding one, it has achieved some fame with users who have adapted it to Canon and Nikon systems. See here:<br>

    <a href="http://www.16-9.net/lens_tests/pentax645_fa35mm.html">http://www.16-9.net/lens_tests/pentax645_fa35mm.html</a><br>

    Here's a quote from the above site: "<em>This is simply the best way to obtain maximum shift movements on a Canon digital body. The Zörk Panoramic Shift Adaptor permits movements of up to 22mm, and is the only system designed for DSLRs to accommodate parallax-free stitching. The lenses I'm selling with it have been chery-picked for ultimate performance: the Pentax FA35 is just the greatest medium format retrofocus wide angle ever. The SMC-A 55mm f2.8 is a cracking manual focus Pentax 645 lens that outperforms the Hasselblad 50mm CF. And the butter smooth manual focus 150mm f3.5 is even better at distance than the Hasselblad, Mamiya and Pentax Macro 120mm lenses. In my opinion (and that of Zörk in Germany), the Pentax 645 range is the best array of MF lenses ever, with a beautiful, Zeiss-like drawing style and bottomless resolution. Until a digital Pentax 645 option arrives, this remains the best way to unlock that potential in the digital realm</em><br>

    The 120mm macro is the sharpest, most substanial lens I own, but it suffers some at infinity and is very heavy; it is not my first choice for packing unless macro photography is the point of the trip. The 150mm f3.5, on the other hand, is no larger than a 35mm lens; it's small and sharp (see the site above). The 200 is ok, but not great; however, the 300mm ED is outstanding. I'm sure you know this, but a 300mm on the 645 has about the same view as a 200mm on 35mm.<br>

    The MLU is really not necessary, I'll refer you to:<br>

    So enjoy your camera.</p>

    Strange CS3 Behavior with Large TIFF Files

    in The Digital Darkroom: Process, Technique & Printing

    Posted

    <p>I'm hoping some of you computer/PS folks can help me with an intermittent problem with CS3. I shoot 6x7 film and work with the scan in CS3. The files are quite large (500MB) and I'm accustomed to a slow workflow. I tried to print a file I had been working on and PS informed me that I need to install a printer (I've seen this message before, but it hasn't appeared for awhile; usually rebooting solves the issue). So I tried to save the file and PS replied that I didn't have enough memory. I resized the file from 500 to 70 MB and PS would then print and save. I use an Intel Duo Proc E6550 (2.33GHz), 4 GB RAM (3GB switch on) with XP pro (sp 3). CS3 is on C drive, scratch is E ( different physical drive) and D drives. Any suggestions ?<br>

    Thanks.</p>

    What's your preferred method of digitizing 120 film

    in Medium Format

    Posted

    Another vote for the 9000, with the caution that you must use a glass carrier for 120 film; the supplied carrier is useless unless you convert it to a glass carrier as described here:

    http://www.photo.net/digital-darkroom-forum/008Jf3

    Edward: the "interesting ICE artifacts" you refer to is one of the reasons I kept my Minolta DSE5400. The Minolta does a better job with 35mm, especially Kodachromes. Not only is the increased resolution worthwhile,but the

    Minolta doesn't produce the "worm tracks".

    I recently had a troublesome slide scanned with a new Imacon/Hasselblad X5, the reults were no better than those I am getting wiith the Nikon.

    Pentax 6x7 Lenses on Pentax Digital?

    in Pentax

    Posted

    Hi Steve:

     

    I used some of my 67 lenses on a DS and agree with most of the previous comments (except the salesperson). I used my DS to check the 67 500mm f5.6 vs the 300mm ED + 2x. You can see the shots via this thread: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00KyqS

    There is a full frame shot with the 300 wide open and it is quite sharp. I also once compared the 50mm M f1.4 to the 67 55-100mm zoom once; the 67 lens was the equal of the 35mm lens (but a lot heavier)

     

    It seems to me that the real value of the 67 (or 645) lenses on DSLR would be with something like the Zoerk PSA shift adapter, allowing the use of most of the image circle of the 67 lens by stitching multiple exposures producing the equivalent of 40-60MP. Unfortunately the adapter is expensive but it can be ordered to fit almost any DSLR not just Pentax. I was waiting for the Pentax 645D, but now I may try the Zoerk.
