Beautiful and color rich set of images, thanks for sharing I think this subject is a perfect match to the color capture values in the sd Quattro! Which lens did you use?

Thanks Larry, they were all taken with the Sigma 17-50mm F2.8. It's not a perfect lens, it suffers from green flare and can vary on the edges. AF is also a bit pedestrian on the SDQ. That being said, it's very sharp and if you stick it on a tripod and manually focus it becomes an excellent lens with a nice range. Much as I'd like to have the Sigma 18-35mm it's range is too limiting for me and I don't need the faster maximum aperture. The good thing about shooting on the SDQ is that it has nice leeway for cropping the sides if necessary and I often shoot 1:1 aspect ratio anyway. I also use the Sigma 70-300mm F4-5.6 DG APO Macro , it has an annoying rotating front element and you can't auto-focus it on the SDQ, but it is an excellent lens, which is cheap as chips, and on a tripod it performs way above it's price point. It's my F11 and be there telephoto option.

As for the 17-50 2.8 OS, yes, it is very sharp. In portraits almost too much. I don't understand the AF issues in the sdQ, but when it is in focus, wow is it sharp. Every time I have set up some sort of test to try to figure out the focus issues (on the sdQ) it works great. Leaving me to wonder why I wasted my time.

It is one of those lenses listed by Sigma that isn't guaranteed to work fully effectively on the SDQ. I find it can miss focus by just a tiny amount, but enough to be noticeable, sometimes it does it, sometimes it's fine. Manually focusing it using focus peaking on a tripod eliminates that. Although the SDQ EVF isn't the best I have no problem hitting focus bang on using it with focus peaking. There are a shortage of options for the SDQ, and it's getting worse, but I have the 10-20mm F3.5-5.6, the 17-50mm, 70-300mm and 30mm F1.4 so I have enough for what I shoot. None of these lenses are perfect but if you shoot them to their strengths they're all capable of excellent results.
