Latest Review Posted | Sigma EX DC J 10-20mm F4-5.6 This was my first wide angle lens. I bought it to avoid having to deal with the kit (it was not bad, but not wide enough and the corners weren't great). I am happy to report that when stopped down the lens performs beautifully. Corner to corner sharpness. Good high quality plastic built too. Distortion is present at the wide end but it isnt always visible and it is correctable. The only real downside is that it does not work with infrared modified cameras. The lens causes hot spots. But then again, it was not designed for that purpose, so I cannot deduct any points for that... |
