This is my first legacy lens. I'm getting some nice shots but wonder if anyone can tell me if what I'll describe is normal or if there is a way I can improve it: When holding the shutter down halfway, or when pressing the lowest soft key for magnification on manual focusing, I'm seeing tons of noise and a very red/yellow-looking image. Fortunately, when I take the shot the result has good white balance, expected noise level (less), etc. For a moment after taking the shot on the preview, I can see the focus peaking and the white balance is good. Am I doing something wrong? (My bet is 95% that I am.) I have live view on. This is a 37-year-old all-manual macro lens so no electronics possible. I have tried it in manual, shutter priority and aperture priority with the same results. It would be great if I could see what I'm doing...! Last, when I go past 1:2 magnification, my shots get very hazy - like a whitish cloud over everything. I think this might be the length of the lens and it's interference with light but it looks like more than that. I've kept the subject lit quite well but still seeing the whitish haze at this magnification. Thanks for any advice. Will post a couple of shots next.
