Sironar W 210 vs Single Coated Fujinon W 210 for 8x10?

How much more generous is the image circle and coverage of the Rodenstock Sironar W 210 lens vs an older single coated Fujinon W 210 (mine is in a Seiko shutter) with the writing inside the the inner ring of the front element? The older SC Fujinons have a reputation for having a more generous image circle than their later MC brethren.

This would be used as a wide angle on 8x10. I will mostly be contact printing, though it is conceivable I could enlarge 8x10 if I ever get to setting up my Zone VI enlarger.

One big advantage for the Fujinon is that I already have it.

Thanks.

Sincerely,

Hany.

The Sironar-W is stated to have a 352mm image circle at working aperture. The Fujinon W is claimed to have an 80deg coverage too (the same as the Sironar-W lens), so it should have a similar image circle as the Rodenstock lens. It is possible that the Rodenstock in real practical terms does have slightly more coverage, but it's maybe 1/4" or so, nothing much more.
I doubt that the Fujinon would deliver the same overall image sharpness etc. if you look at an MTF chart. Having said that, I guess the Fujinon is still a very good lens. As Fuji have stated that the lens covers 8x10", you should get very good results with enlargements too. (For contact printing the Rodenstock is big overkill.) If you are pleased with its performance there is no reason to spend a lot of money on the Rodenstock. Speaking of costs, the Sironar-W takes the humble filtersize of 100mm, compared to the 58mm filters that fits the Fujinon.

They are the same. Any 'differences' are absorbed by the imaging process.

Use either one straight on, have fun.
