Review: Sigma 10-20mm f/4-5,6 DC HSM AF

Sigma 10-20(Will not work on full frame, on DX equivalent to a 15-30mm)

A very good performer indeed, if you don’t care about it’s border sharpness (only so-so).

If you need it as a reportage lens buy it and you will not regret your money; if you want it to use as a landscape lens try to test it before you buy to see if it met your expectations.

Full size:

100% crop:

For infrared use it is a “mixed bag” lens: really really sharp in the middle of the frame, but often with the borders not up to my standards and, only sometimes not everytime, a big hotspot in the middle.

Again: if you can try it before you buy it.

Rating: ★★★½☆ visible light
