Tipitytoptastic Sigma 10-20mm EX Superwide Brilliance.,
This review is from: Sigma 10-20mm f4-5.6 EX DC HSM - Canon fit lens (Camera)
I'm a pretty well seasoned photographer type but a bit a few hours spent with this lens has convinced me that I needed one of these lenses immediately.
This is one of their Sigma EX range which according to the bumf means it's better engineered, better built, higher quality materials, at least on the outside, and to be fair that's about right. The focus ring is not too loose, not too tight, the motor is quick and quiet and it's all finished in a nice kind of grippy tactile stuff. It's got a good solid metal mount but as expected it is fairly weighty lump when bolted to the camera, but not in a bad way, just solid and well balanced.
It's internally focussing which is good. Because the lens is physically fairly short no outside part of the lens will spin wildly in your hands when focussing, all the spinny bits are inside so it turns out to be a bit of a joy to handle.
Probably best to note right now this is a superwide lens so look elsewhere if you're after something other than this. However, the depth of field on this thing is enormous so watch out of you'll be noting the accidental inclusion of your feet in many snaps. For the right application though, this lens is a stormer. I've used it for some stunning travel shots, big moody sky landscapes, funky nightclub shots and portraiture snaps with a fun exaggerated perspective. You can pull off some very funky modern photography techniques very easily with this one.
Results are great, err spectacularly wide, sharp (far outer edges are less so but it is superwide so that's expected), well controlled aberration and no obvious loss of colour. All very good and a bargain price. I also looked at the Canon and Tamron equivalents. The Tamron cost a bit less, was lighter but felt a bit cheap and plasticy in terms of build quality. I couldn't fault the Canon other than its more offensive price.
I'm now a happy Sigma convert. I can also recommend the Sigma 18-200mm DC OS if you're after a big image stabiliser zoom too.
Anything else, umm, yes, it's an uncomfortably large glass area to damage at the front so make sure you grab yourself a 77mm UV filter. That'll protect it and is easier to swallow financially than the cost of a new front element repair. About £25-30 high street of £10 to you sir from Ebay.
Anyway's - Sigma 10-20mm is recommended.
