I know I think too much into this stuff.......
I recently aquired a Sigma 50-150 2.8 lens (yeah me!) and spent most of last weekend trying it out. I also took some pics of some cows in a field with both the Sigma lens and my DA 35 2.4.
When viewing the photos afterward, I noticed a big difference in the colors of the photos. Mostly the greens which the Pentax lens had much deeper where the Sigma were a lot more bland. I guess I better post a couple pics for an example:
Images are clickable for larger size.
These 2 shots were taken within 5 minutes of each other and lighting conditions did not change as it was heavily overcast and actually in a slight fog/cloud. They were taken in raw, and run through DxO with just standard settings with a jpeg output.
I was really amazed at the difference in the colors or rendering of the 2 images. I did find that I could tweak the Sigma image to mimic the Pentax one, but I don't want to go through that with every set of images I take with the Sigma lens.
I am quite happy with the lens, and had taken quite a few shots before these over the weekend and was very pleased with them. When I was at the field shooting, I needed a wider view so that is when I switched to the 35mm lens. When I viewed those pics afterward I was quite surprised with the difference.
Is this something typical of the rendering of a Sigma lens vs a Pentax lens?
