    Lens length preferences in 7x17 format?

    Still trying to figure out whether "normal" will be 270 or 300.

    Lens length preferences in 7x17 format?

    Once again I am indebted to each of you guys for your great, informative responses. I am pleased to say that I am likely at a less advanced spot on the Learning Curve than all of you are. But that's what makes it so much fun!!

    Jim Galli:

    Thanks for the FS717 I recently bought from you on Ebay. Nor have I forgotten that I owe you a print in return for the one you sent me! I am currently trying to decide what size bed extension I want. Steve Sherman kindly sent me photos of his add-on 2" extension which allows use of a 480 without having to lengthen (original) bellows. I've also had a good friend/machinest refabricate front standard/lensboard brasses to put the front tilt back into business. Secondary bellows was in great shape, by the way.

    I have had a ball with this camera! Thanks, again, Jim!

    Emil, are you shooting your 250 Fuji SF at infinity and getting sharp to the edge images? I tried mine from f/4.5 all the way through to f/22 and got nothing but mush 2/3rd's the way out on my 7x17 negs.

    Oren, "normal" for me is 355mm on 7x17.

    Lens length preferences in 7x17 format?

    As a compromise in terms of size and weight between the 360mm Fujinon A and the bigger 355/360mm f5.6/f6.8 plasmats, would the 360mm Graphic-Kowa be a good choice in this focal length for 7x17? Of all the Computar/Kyvytar/Kowa lenses, this seems to be one of the most common and most affordable of the longer focal lengths. Of course, there is a reason for this. From scouring the archives, I know that the Graphic-Kowas (at least in the longer focal lengths) don't provide nearly as much coverage as the Computars and Kyvytars. I've read comments that this lens definitely doesn't cover 12x20. Has anyone actually used one (landscape use, at/near infinity) on 7x17 (or even 11x14)? If so, how was the performance? Did it cover? Was it acceptably sharp in the corners? If so, how much left for movements? Any comparison between the 360mm Graphic-Kowa, 360mm Fujinon A and/or 355mm G Claron would be appreciated.

    Ironically, I had one of these several years afo, but I only used it on 8x10.

    Thanks,
    Kerry

    Kerry, I think it was a 360mm Kowa that I borrowed/bought a #3S shutter from you some time back. If it was the 360 Kowa, I tried it on an old Empire 11x14 camera that I also happened to have at the time. It did not cover the format.

    Lot's of "if's". Sorry 'bout that. The memory might be going...

    I have a 14 " blue dot trigor that covers my 8x20. It would be a great lens on a 7x17.

    Hi Robert,

    15 inch turner reich. I also used a 305mm g claron, but the bellows sagged a lot. The g claron did not produce a dramatically sharper neg so I just use the 15 inch

    Kerry,

    I put the 360mm Kowa Graphic on a board for a 12X20 some years ago and looked at the image . This lens did not come even close to covering 12X20, in fact, l don't think it would even cover 7X17, but I could be wrong.

    Never had a 360mm Fujinon A.

    The 355mm G-Claron covers 12X20 nicely. Not much room for movement, but good image quality all the way to the corners.

    On the other hand, the 355 mm f/5.6 Symmar Convertible that I once owned covered 12X20 as well as the 355 G-Claron. Plus, really bright image on the ground glass from that big aperture. I gave it away to a friend with the naive belief that the 355 G-Claron was better. Big mistake.

    My favorite lens for 7X17? That would be the 240mm Computar, 300mm Computar, 450mm Nikkor M and 600mm Fujinon-C.

    Christopher, the Fuji SF 250 stops way down to f 90. Even though only marked to f22 you really need to go way smaller in the f stop to work this 3 element lens better in the corners. Emile.

    My basic 7x17 kit consists of a 355 G Claron, 450 Nikkor M and a 24" RD Artar (aluminum). This kit works for 7x17 and 12x20.

    I can then suplement (depending on where I am going) one or more of 3 Computars, 210, 240 and 270. I have used each of these at times on my 7x17.
