Great lens
This is a great affordable L series lens. It is wide enough for a full frame or crop body. It is built like a tank and a very reliable lense @ f/4. No need for 2.8 if you use a flash or light your subject correctly.

Excellent Lens
many of my shots utilize this fantastic lens. It is perfect for indoor gatherings and that's when I use it the most. All of the photos I have takken with it are, in my opinion, suburb.
