Title: Great Lens for landscaping shoot - very wide
Review: This is a great lens for landscape it produce very nice vivid colors. I did not notice any vignetting as other in the forums saying also I pick this lens over the new release Tamron 10-24mm, which wider end longer reach and faster aperture f/3.5, because of where the lens is made(not in Japan). The price of this lens still higher then the new release even though it has been release to the market for quite awhile now.A lot of peoples in the forums rating the Sigma 10-20mm very high, I own a couples sigma lens and I don't think the build quality would match to a Tamron brand and as far as pictures quality goes....I don't see any differences. Here is a few problems with Sigma, stiff zoom, mechanical gear issue, lens glass is a miss & hit, so why pay for something that already having so much issues?
Is the review positive or negative?
