Enlarge lens 150 vs 135

[jnantz]

I listened to the advice I got and found complete sets of silver Componons, some of which I cleaned out myself. Ken Ruth (Repair Guru Photography on Bald Mountain) explained that the Componon comes apart in complete optical groups. Use spanners and take the groups to the kitchen sink. Dawn Dishwashing Detergent makes 'em shiny clean again, some of mine were down right milky, they all came clean in the end except one. One 360mm was cloudy in the middle, I traded Jason Lane some Speed Plates for that one. I really think these are every bit as good as silver Schneider Symmars, in fact side by side, it's hard to tell them apart. I paid $50-$100 for each, ended up with a set of complete matching pairs for my TLR Normas.

These olde lenses can be underrated. Work just fine for my uses. 16x20 is as big as I can go.

well stated!
3 clicks past wide open nearly every clean enlarging lens made is great.
but its like everything else photographic, it's a lot of fun to make things as expensive and difficult as possible
