Review on Sigma 17 70Mm F2 8 4 Contemporary Macro by Jasmit Singh ᠌

Bought over a year ago used. Before that, I used only whale. Excellent staff for reasonable money. On my Canon 450d, it produces a sharp picture at all focal lengths. Has pros: Sharp, after the whale sky and earth, more aperture, extended range of focal lengths (again compared to the whale) Blend included. Fast autofocus, macro mode. Different cons: A feature of Zoom is that it moves independently if you do not hold it up when shooting (due to its own weight, the trunk drives back), you must hold it with your hand. Filters are a bit expensive, even a simple protective one.
