This lens has a pronounced flare problem. I noted a strange color balance with this lens sometimes. So I did a test. On a sunny day in winter, I took a photo of the white snow, excluding everything else around but snow. I did a shot at f8 with a SMC-Takumar 28mm f3.5 and another one with the M24-50. On the first one the snow was white, on the second one it was green. Why? I had green firs all around me. The 24-50 picked up the reflection of the firs. This is one way flare can affect a lens. To give such an effect the lens must have a design flaw (baffles, optical design). It has been corrected in the A version of the lens, a rather good zoom.
I'd llike to know if anyone having the lens could reproduce this kind of experiment, as my slides from the test are not around and I don't have the lens anymore. |
