Sigma 100-300mm f4 EX IF HSM APO

Review Date: Jan 12, 2011 Recommend? yes | Price paid: $899.00 | Rating: 10 

Pros: Extremely fast HSM autofocus, great image quality, sharp even wide open, good build quality.
Weight... after nine hours of this on a 7D in the sun, unhappy arms. And while the overall build quality is very good, the finish is wearing off.

I got this lens about four years ago now and its been an absolute workhorse. It has extremely fast autofocus (perhaps due to the HSM motor although my other sigma with it doesn't focus this fast), great color, contrast, bokeh, etc etc etc. Its sharp wide open which is good because I really wanted the 2.8 version :-/ so I'll take as much light as I can get. Its definitely heavy but well built. The finish is coming off a bit now but I'm not sure if thats because of the lens or my own ineptitude in taking care of my gear. Other telephotos I've used include; Nikon 80-200mm f2.8 via my old job, older but lovely however I shoot Canon now, not Nikon. Canon 75-300mm III that I borrowed on a road trip from a friend and immediately handed it back to them. Sigma 120-300mm that a friend let me try.... but I don't have $3000. Canon 55-250mm IS and 70-300mm IS but I wanted a fixed aperture. I can definitely recommend this lens for sports as well as nature photography. A little hefty in weight as well as price right now but well worth it.

Sigma 105mm f2.8 EX Macro 1:1 Lens

Review Date: Jan 12, 2011 Recommend? yes | Price paid: $284.00 | Rating: 10 

Pros: Extremely sharp even when wide open, good build quality, great bokeh, color, contrast, etc.
Autofocus is crap but who uses autofocus on a macro lens?

Bought this on a lark about two years ago from KEH, had some extra cash and thought it would be fun to try macro photography. I had shot with the Canon 100mm 2.8 USM and the MP-E 65mm ... but I didn't have that kind of extra cash. The Sigma has been excellent, tact sharp for portraits or detail work. Even strapped it on for a couple of action shots during a recent Supermoto event in Tallahassee. Autofocus is fairly worthless but macro and manual love each other. Contrast is great, color pops and the bokeh is smooth and clean. I can definitely recommend this lens.
