This is a review of the Sigma 20mm f/1.8 lens. It is the widest, large aperture prime lens on the market and is a very cheap alternative to the Canon and Nikon 24mm f/1.4. Although this lens is great for the money you pay, it is obviously in a different league than the respective 24mm’s. It is worth noting that this lens can be purchased for very cheap on ebay (I got mine at ~40% off!), but keep in mind that Sigma lenses can frequently have quality control issues. This lens is no exception and I am sure that if you are reading this you have already read other reviews that talk about soft spots even when stopped down on some “dud lenses.” Having said that, buy from somewhere with a good return policy and you wont be disappointed.
Overall review: 8/10
- Good build quality
- Good value for money
- Great color rendition and contrast when stopped down
- Clever manual focus to AF clutch mechanism
- HUGE filter thread (non-standard size of 82mm?!)
- Soft corners while wide open
- Could be sharper when wide (it isn’t too bad in my opinion)
- Comes with a cheap lens cap!
