Sigma 50mm f1.4 @ f1.4 -> WOW
It's amazing how sharp the Sigma 50mm f1.4 is at f1.4 ... once you manage to nail the focus that is ... which for me is not that easy. As with the 85mm f1.4 you can end up with quite a lot of green fringing at fast apertures (which, yes, you can remove in SPP). In any case, a very fine lens, the bokeh is very smooth and color rendition is great.
Focus in the pic below was on the head of the statue/sculpture:
Nice bokeh alright, Hardy.

I believe the focus shifts a bit with the aperture, so even a calibrated lens can benefit from a bit of manual fine-tuning. The lens is otherwise well described with a WOW, and on my 1.7 crop SD15 even the corners are sharp wide open.
I quite often use manual focus. My main tasks (which I should really do quite soon) is that I have to get the viewfinder dioptre adjustment setting right. Currently I can focus on close by objects fairly well, but if they are further away, my success rate drops significantly.
This was the first lens I bought from Sigma, for my Canon 30D. It has worked very well. I did a fairly large project with it over the last couple years photographing paintings for an artist.
Here is a link. Beware lots of photos here, and resolution is limited for protection of the images: http://www.mike-yengo.com/
I made one of these into a 30x40 wall mount print (10508, first shot in the first gallery, thru Meridian Pro on the web) and it turned out well. Lots of bayer artifacts in the fine details but no issues at all with sharpness.
I wish I had one for my SD1, but I have the 85mm F1.4 instead, and certainly no complaints about this lens either!
