Is it just me? Or does the color cast on some lenses change as you stop them down? Here is an example of a shot taken with a 75mm Summicron Apochromat wide open and at f/5.6. The white balance was set manually in Lightroom using the exact same temperature and tint settings for both. The images were taken only a couple seconds apart, so I know the lighting didn't shift. Both images are cropped to, roughly, the central ⅔ of the original image. The image taken at f/5.6 has much stronger magenta tones than the image taken at f/2. I see the same thing with my 50mm Summilux Asphere (though to a lesser extent--mostly the Summilux is just a bit warmer than my other lenses at all apertures). Has anyone else noticed a shifting color cast with aperture? It's not a big deal for my photography since I tend to leave white balance set to automatic in the camera and adjust in software after the fact using RAW files only, but it surprised me nevertheless. I don't recall seeing this mentioned in this or other forums. If it makes a difference, RAW conversion was done using Lightroom 4.4 using the embedded profile (my preference over the Adobe Standard profile which, on average, produces less consistent results). No sharpening or any other adjustments aside from cropping to the frame size and applying the same white balance settings to both images. - Jared p.s. Obviously these aren't intended to be interesting photographs--I'm just trying to learn the characteristics of my new 75mm lens and was shooting a flat subject to eliminate the effects of depth of field--was trying to get an idea of field curvature, optimum f/ stop, etc. and was surprised to see a difference in color.

Hi all, I have taken some photos on a wedding where some of the photos turned upp with a strange color effect on the grooms jacket. It is present on a lot of pictures when he is standing in sunlight. Have you seen this before? Any idea about the reason? https://www.sugarsync.com/pf/D6797873_7273759_114023 I shot in raw. Cheers Fredrik
