Query: This is on my camera most of the time

Of my several lenses (including the L-series 100 mm macro and 70-200 mm telephoto), this is on my camera much of the time. It takes great shots on my 5D Mark III and it's so nice, compact and light weight. I chose this lens over the higher f stop versions with the thought that the 50 mm is very common and has been well researched and developed and should be a good value.. I have not been disappointed and anticipate sticking with this version. Fyi - I am an avid hobbiest.
