Today I got my first wide angle lens, a Sigma 10-20mm f/4-5.6D EX DC HSM. I’ve been very impressed with the quality of Sigma lenses since I got the 70-300mm and this lens didn’t disappoint me. The 10-20mm is very sharp and the auto focus is extremely fast and quiet.
Since most of my lenses are longer zooms, this one gives me a new perspective. It should be great for landscape photography.
Both of these shots were taken from the same spot at 20mm and 10mm.
