Peach Blossoms #1 Hermagis Eidoscope 14 1/2" f4.5
I used 3 lenses for this comparison.
First was a Hermagis Eidoscope portrait lens of 14.5" length.
I shot it wide open for the first
shot, then stopped down to f11 for the second.

Next was a venerable Petzval that the postman
had just brought to me a day previous.
It is a French import made for Folmer & Schwing
and seems to be quite early as there is no
aperture, just a slot for waterhouse stops.
Curious, I dis-assembled it to see if the usual penciled
Darlot signature might be present on the
side of the front element combination. It was not,

but penciled in the same manner was the information
that it is a 10 1/2" lens. I couldn't make out the rest.
I had a waterhouse to stop it down to f11 for the next shot.

To round things up to even
numbers for the JOBO, I shot one final image.
It is done with a mint 250mm Rodenstock Imagon.
I shot it wide open witn no diffusers.
What you see is all the "buzz" the Imagon can deliver.
I'd never used an Imagon before but it seems to
have promise if you like fuzzy pictures.

My conclusions are incomplete.
Certainly you can get too much of a good thing.
My favorite of the test is the more
conservative picture done with the Eidoscope at f11.
These are 8X10 done with a Century 9a studio camera on Efke 100 Cirkut film.
As always, your thoughts are important to me.
