Hello Team,
Have option to get either 150 or 180mm lens for sinar Alpina...
A) what do you prefer 150 vs 180 and why?
B) would image circle be greater with 180mm?
C) which lens would emulate more closely 50mm on 35mm camera?
Many thanks for your feedback!

Hi Harlequin
A.
I don't have a 180 but I have a 150. it's a computar, ( I think 6.3 if that matters ). I bought from a guy who claimed it was magical and
covered an 8x10 negative ( it was on a 8x10 sinar lens board ) .. not sure it does, I have talked to people, some say it does some say
it doesn't, I never bothered to try so I'll just say ¯\_(ツ)_/¯ I prefer the 150 because that because its all I know.
B.
if the lens is a Schneider 105 / 185 convertible, it
might throw a large image circle. my converted 210 / 370 throws a gigantic image circle so who knows what the 185 throws ..
it might be a nice portrait lens, Schneider used to suggest "portrait / landscape " use for their converted lenses. I've used the 370 to shoot group portraits, it worked well ( stopped down ).
C.
The "rule of thumb" of the conversion factor between a 35mm lens and a 4x5 lens is take the FL of a 35mm lens and multiply it by 3 ...
that will give you the
ballpark figure of what its equivalent in 4x5 format
might be. I say rule of thumb because it is between 4 and 5 and closer to 5 ..
so to answer your question, it's "around" 150...
have fun!
