Just got the Sigma 50 1.4, after much debating back and forth...Then
went so far as to even sell my Canon 50 1.4 on Ebay. I have to
admit...I like it a lot!! Granted I MA on my 5dll to +6, but it is
very sharp, even at 1.4!!! A little soft along the edges(as reported),
but everything else is fantastic. And very useable at 1.4. F2 and on
is exceptional. My Canon I couldn't use, really, until 2.0 or 2.2.
Glad I purchased!! Here are a few samples. the first is one of my
fences along the house-ISO 100, 1.4@1/400...the second is our dog
Rajah, and our son Mason(well sorta kinda), ISO 100, 1.4@1/640. Rajah
was processed in SilverEfex Pro(trial vesion), then lightroom, with no
sharpening whatsoever....Both in camera jpgs, not RAW. Let me know
what you think....[img]/cfs-file.ashx/__key/CommunityServer.Components.UserFiles/00.00.00.22.00/Rajahbw-_5B00_800x600_5D00_.jpg[/img][img]/cfs-file.ashx/__key/CommunityServer.Components.UserFiles/00.00.00.22.00/_2D00_3860-_5B00_800x600_5D00_.jpg[/img]
