Summary: This is a very nice lens, and it is also quite affordable. It delivers very sharp pictures, even at the 400 to 500 range. Given that the cheapest Canon 400 mm prime lens starts at $1250 and the comparable Cannon 100-400 mm zoom lens starts at about $1350, this lens is a steal.
Summary: I just acquired the a new Sigma 150-500mm lens for not much more than what they go for used...Super Value...especially with case / straps accessories & 4 year warranty. I am a hobbyist and shoot with a Canon 70D. I also have a Sigma 105mm Macro and am very happy with it...
Summary: I have had this lens for 6 months , use on my Canon 70D For hobbyist's like myself, this lens is great value I use it for BIF, wildlife, and moon shots, and it has performed well Weight: not too heavy for handholding, although practice helps Build quality: no issues, For those of us on a budget,...
I am very glad I did make the investment on the lens

Summary: I should start and say I use this on my Canon 7D original series camera. During the summer I photograph a lot of airshows in the Midwest. I wanted to get something with significantly more reach but I wanted to explore options from different vendors.
Summary: Awesome lens for the price! Even if the aperture width is high, I can still take some awesome pictures! I've only been using it for astrophotography on my EQ mount so far, but I've gotten some great results! It is a solid lens, not too heavy though, which is nice to carry around.
Summary: For the price this is an extraordinary lens. It's heavy—almost a pound heavier than the Canon 100-400mm L lens—but not too heavy: you can still hand hold it even at 500mm at 1/60 and get acceptable images. It is very sharp at all focal lengths and apertures.
