9-1/2" f6.8 Goerz Dagor Am. Opt. Co. for 8x10?

I am just delving into 8x10, and looking for a good moderate wide angle. Does

anyone have information or experience with the 9-1/2" f6.8 Dagor, in regards to

image quality and coverage? Or perhaps a more suitable recommendation? Thank

you.

From this site, the lenses that stand out are the Fujinon 250mm f6.7

(not f6.3), the 240mm g-claron, the 250mm Wide Field Ektar (2nd

widest), the 210 Angulon f6.8, the 210mm Super Angulon (huge and

expensive), and the 210 Super Angulon XL (not so huge, but much more

expensive).

The 9.5 inch dagor had a published image circle of about 340, which is

just large enough to cover, but not so large as to give significant

movement.

I would add that the following image circles:

<p>

210 Angulon f6.8: 382. 210 Super Angulon: 500. 210 Super Angulon XL:

500. Wide-field ektar: 420. Fujinon f6.7 250mm: 289 (or 298?). The

image circle for the 240mm G-Claron is significantly wider than

published.

Hi John,

Neil's reply on the image circle is useful information, and I would

like to add some other thoughts to consider. I settled for a 10" WF

Ektar because of the image circle and relative affordability. I shoot

BW only and a deep yellow filter would deliver an acceptable contrast

as this lens is single coated only as are most Dagors, some are

uncoated I think. Are you planning on shooting landscape where

usually weight and compactness is more important or architecture

where a larger image circle is necessary for the rise? Do you shoot a

field camera or a monorail? I found that on my Deardorff I can get

enough vertical correction from the Ektar to shoot fairly tall

buildings and industrial structures. Even when the camera is tilted

upward and the standards leveled, I normally get bellows vignetting

before runnning out of the image circle of the Ektar although close

to it. The bellows get so constricted and it's hard to maneuver to

movements unless your camera has provision for a bag bellows.

Anything shorter would be harder and anything wider like the 210

Super Angulon or XL would be overkill if your camera has the same

restriction as mine granted you're utilizing the better part of the

circle. If you don't need that much coverage, the Dagor is an

excellent performer too. They do better at smaller apertures and some

are known to have focus shift. The Gold Dot/Gold Rim versions are

better but command a higher price. If you want to go modern, I would

go for the Fuji 250/6.7. The modern lenses tend to be slightly

sharper and of higher acutance from the multicoating except the G

Clarons which are single coated, nonetheless excellent process lenses

with big coverage and bigger as you stop down. Just my two cents,

hope it helps. Best regards,

Henry

Hello, I use my 210/5.6 Caltar-s II (symmar-s), I originally bought

it for the 4x5 of course, but found that it covers 8x10 and is great

for landscape work. If I were doing architecture or studio work then

it would not have enough coverage, but it works great in the canyons

and mountains of west Texas.

Hi John!

I own and use 9-1/2 f6.8 Dagor for my 8x10 Deardorff. Wonderful lens.

I have the golden dot version. Small, sharp, contrasty with a special

glow. Enough coverage for 8x10. I usually shoot at f45.

John,

I just purchased a 7" X 17" camera which came with a 91/2" Dagor

6.8 lens. I shot some film and found that the lens just barely

covered the 17" diagonal. Dagors are known for huge image circles

and also can vary greatly from published image coverage. THis lens

should cover 8 X 10 with no problem. Steve Sherman
