I borrowed the classic Contarex 21mm/f4.5 Biogon with a special adapter for M-mount, and used it on the R-D1. There is no rangefinder coupling, of course. But I find the lens is doing something funny to the metering. If I shoot into the light, e.g., sunset, with huge expanses of clouds, etc. , even if I down the EV to minus 2, the centre of the picture is still a big ball of light, with no distinct shapes. The pictures are very good if I do not shoot into the light, with hardly any vignetting.
I read somewhere that such non-retrofocus lens puts the rear elements too close to the meter, and that the lights do not meet the meter at a perpendicular angle, etc.
What is the problem here?
