7x17 lenses?

[Arthur Nichols]

Hi,
I use a 16.5 inch F/9 repro claron in a compound shutter. For some reason it covers and it is small and sharp. I also use a 19 inch F/11 Artar and a 19 inch F/9 Turner Reich repro lens, also in a compound shutter. From what I can tell the TR has more coverage than the Artar and is also is surprisingly sharp. Of course as already mentioned the 12 inch Dagor more than covers the format and is nice and sharp. My 210 Angulon doesn't cover it is way too soft at the corners. Maybe others have had more luck with the Angulons covering this format, as I always seem to hear about them in relation to the 7x17 format, but not for me.

Hi Daniel.
Here's a list of wide lenses that I use on a 7x17
150XL Sch, 270 F9 Computar, 9 1/2 Gold Dot Dagor, 12 inch dagor, 14 inch Gold Dot Sch (soft on the edges) I seem to remember trying the Kodak 250 WF and it didn't cover, but I may be wrong. Hope this helps....Phil.

The blue dot is a great piece of glass. I've never owned a 14" gold dot so i can't do a comparison but mine covers my 8x20 with slight movements. I just had it mounted in a copal 3 by grimes with grimes lens caps. This lens may be for sale in the next week or so.

And I know I'll regret it

The only lens I had to compare my Blue Dot to is my old uncoated 16 1/2" Dagor. By finding the edge of the image circle of both lenses and shooting them both at the same aperture. The Blue Dot Trigor was significantly sharper than the Dagor near the edges of the image circle. And it appeared more contrasty than the dagor. Now this may not be a very scientific test since I'm comparing the Trigor which is coated to an uncoated Dagor. I think it will be a perfect 7x17 lens

Robert,

Thanks for sharing the info on your lens. If you don't mind me asking, how much did it cost to have it mounted in a Copal No. 3 shutter. Also, when you get a chance, if you could weigh it and post the results, I'd appreciate it. I'm a bit of a fanatic about weight (says the 7x17 shooter).

I'm hoping this lens will be the "perfect" 14" lens for my 7x17. I really like the 210mm focal length on 4x10 and consider it my "normal" lens on that format. Since 14"/355mm on 7x17 is equivalent to 210mm on 4x10, I've been looking for a lens in this range that would cover 7x17, yet not be too big or heavy.

Kerry -

Have you tried your Fuji 360mm A on the 7x17 yet?

Not yet, I want to test it directly against the 14" Trigor.

Kerry, I'll have to find the receipt when I get back to give you the exacts. But since you already have a copal 3 that should take a big sting out of the costs.I think off the top of my head it was in the 800 range with the price of the shutter included of course. I have an itemized bill so I can probably give you the machining costs and install when I get home. I'll pm you.

Old Fuji 360 (lettering inside) will easily cover 7x17. I am using my fuji on 8x20.
