H.Roussel Paris Kynor 3.5/50 enlarger lens

[alex ph]

It is another enlarger lens which lacks any trace of test info in the net.

It has a 30mm screw mount and is really small in size. The aperture scale goes from f3.5 to f11 and the lens barrel is identical to this Trylor close relative. Looking at the glass surface I am tempted to say it is not coated, but looking at the images I'd say it is.

Some quick shots on Sony Nex with autocontrast applied:

#1 Wide open


#2 A 100% crop from the previous


#3 At f5.6


#4 Close ups using a helicoid


#5

Nice to see more photos taken with H.Roussel Paris lenses.

Glad you found that worth-while, fellows!

Jamaeolus, the lens looks precisely like Trylor in the post linked above, except the name on the beauty ring which says Kynor.

Making some more shots in the open air I found out a nice retro look the lens renders. I observe alongside a pretty subtle change of in-focus areas when changing the aperture value. You may distinguish wide open from f5.6 and even from f11 mostly by OOF fuzzyness. Some more examples follow.


#1 At f5.6, unprocessed besides resize


#2 At f5.6, autocontrast


#3 The same WO, unprocessed, just desaturated. A nice mild glow


#4 At f5.6, autocotrast and desaturated


#5 WO, autocontrast


#6 The same at f5.6, autocontrast. Not much difference in central sharpness, right?


#7 WO, autocontrast


#8 At f11, autocontrast
