Took the recently acuaired Sigma 100-300mm F4 for it's first proper outing on Wednesday. Very hot day so the animals were not to energetic (neither was I). Here is one of my favs.




Will post up some more later. Am liking the lens so far very sharp and contrast is very good. Has similar qualities to the 70-200 F2.8

I like this one a lot. The expression on the cat's face is so poignant. Sharp lens.

spot on, great shot, great lens it appears.

Yes the Sigma 100-300mm F4 is very nice, if albeit a bit rare over here in Pentax mount,

Nice one to share. I'm assuming you were shooting at the 300mm end, which is where these sorts of zooms tend to lose sharpness, so in that respect it does show off the capabilities of this lens.
