210mm Lens for 8x10: Spotters Guide

[Jason Greenberg Motamedi]

The 210/9 Computar has an IC closer to about 375mm at f22, and nearly 430mm at f45.

Yes , that is what I think that OP underestimated the Computar.
Do you have the IC of the Kowa-Graphic 210mm at 22 and 45?

Not at infinity. I had a 270mm version mounted in a shutter and that puppy could not cover 8x10 if you put a gun to my head.

That lens was designed for repro work and the ic on the charts is for magnifications, not "landscape" or infinity work.

BTW, don't forget the 210mm Dagor. Its covers 8x10 nicely.

Thanks for that Schneider link. That also shows an 86 degree coverage for the F11 version of the G-Claron WA 210mm. 86 degrees was used to calculate that 391mm image circle. That document also says 800mm at 1:1, so at infinity that would be about 400mm. Again, I'm just going by stuff posted on the net. I have not owned it, so thanks for sharing your experience!

Do you know the image circle for that nice Dagor for comparison? I did not include a Dagor in the OP because the only two on that link in the OP showed:
210mm f6.8 Goertz Gold Dot Dagor = 294mm
210mm f9 Goertz Red Dot Artar =153mm

Thanks. I'm was just going by data in that link in the OP.

That list is reproduced on a number of sites across the web. Maybe the 210mm section needs to be updated.

Here's my Schneider Super-Angulon 210/8 MC in Copal 3 (500mm plus coverage).....not for a "lightweight" field camera!

Thanks for your picture.

I once almost did a BIN on lens described 210mm Super Angulon on fleabay. Close inspection of the picture showed it to be a 90mm! It was priced like a 90mm also.

The Ilex (also Calumet) 215mm f/4.8 will also cover 8x10 at infinity.

[Armin Seeholzer]

My Kanica GR II 210 has around 360mm covering power!
Macro Sinaron = 350mm ths is not correct at 1:1 it has 525mm as stated in my brochure from Rodenstock.

Cheers Armin

When you read the info a bit deeper you will see the 210 WA G Claron IC of 800mm is reached at a distance between the subject and film plane of 855mm and a 400 mm IC is found at approximately 1000 mm. Infinity would be an impossibly small IC, barely covering 4x5. The angle of view and image circle need to be correlated with the reproduction scale of this specialty lens.

I have no idea what the image circle of that Dagor lens is; it covers at f32. I know from use. Gold Dots usually have a smaller IC and covering power than "regular old" Dagors.

Good luck.

I'd like to see the math on that.

If the angle of view is 89 degrees, that does not change with magnification. The image circle I calculated at infinity from that angle of view is 391mm. At 1:1 it would be near 800mm and that agrees with the chart.

[Jason Greenberg Motamedi]

No matter what the math, I can tell you from personal experience that WA G-Claron lenses function very very poorly at infinity.
