|Canon EF 17-40mm f4 L USM
This is my first “L” lens and my best lens. It stays on my camera about 80% of the time, until it is replaced by the EFs 17-55 f2.8.
The photos here all have fine details for checking resolutions. Some have straight lines near the edge for checking distortion and CA. A few are taken at f4 inside museums without flash.
