Experiences with the SIGMA APO 170-500mm F5-6.3

[YYZPICS]

I know that sigma has the 50-500mm, but its about 5 to 6 hundred dollars more and about 1.1 pounds heavier. What do u guys think about 170-500mm?
If u could post some pics taken with this lens, that would be great.

Thanks...

Some people have managed to get some excellent results with this lens.
However it is not as good a quality lens as the 50-500 and neither are as good as the 100-400L if you shoot Canon.However they represent great value for money but just dont expect L quality and hence be prepared for the higher washout rate.

I have the smaller 135-400mm brother of that lense. It produces great quality if you can use an apperature of 8,0 or better. For the 175-500 with a max aperature of 6,3 I bet you will need an aperature of 10,0 or more to give it decent sharp pics, so it will be a good weather only lense. (just like the 135-400mm) Then it should give you quality close to an L lense or the Bigma.

If froced to go full open, then you must expect some out of focus pics and expect the pics to be very soft.
