First of all, I must say I was not impressed with this lens when I tried it out on my camera in the shop (Park Cameras in London). I could see some chromic aberration or colour fringing in the viewfinder, not a good sign, it has a plastic mount and it has a very small maximum aperture. But, something said I had to own this lens and as far as wide angle lenses go, this was selling for a bargain price.
I have been using this lens now for a couple of weeks short of a year and I can tell you this has become, by far my favourite lens, staying on my 70D almost 100% of the time especially when I go walkabout anywhere in London. The chromic aberration I saw in the shop has not reared it's ugly head and it's turned out to be quite a sharp lens. For the type of photography I use this lens for, I use a tripod most of the time, so the speed of the lens has not been an issue at all and as far as the plastic mount is concerned, It has not fallen off my camera, yet. Considering how much I use this lens, that is amazing. Highly recommended for anyone with an APSC sized sensor Canon, contemplating wide angle photography.
For in depth review of almost any Canon lens, you can't beat this guy:
My name is Mel Sebastian. I am a graphic designer and photographer living in beautiful Berkshire. I have been interested in photography from as far back as I can remember. At my age, that probably means about 3 days. Anyway, my dad was a very keen amateur photographer and what I learned from him has been invaluable to me through the years, and photography has been a source of so much enjoyment for me.
