actually it wasn't light transmission for the Cosina

Here's a comment about light transmission, although it wasn't the one I remembered, I'm still looking for that one:

Hi so after some time of searching I found and bought SMC M 50 f/1.2 And it is briliant

It cost me 400$.
So I made some easy check if it is realy 1/3 stop lighter than 1.4 - I make two photos of wall in manual mode and then open both raw in camera raw. In both time I check "auto" light correction. So difference was exactly 1/3 stop

So Don't worry buy it

K series perhaps? I didn't think they made a 1.2 in the M series?

the whole idea of the M series lenses were about small size, high image quality with a solid construction - the SMC 50mm f/1.2 is built like a tank but it is hardly compact, but the image quality...all I can say is that of all the 50mm lenses I own it is one of my favourites.
