Non Scientific Comparison: Olympus 75mm f/1.8 vs Canon Ef 135 f/2L

Absolutely non-scientific comparison by Tyson Robichaud between the Olympus 75mm f/1.8 and Canon EF 135 f/2L lenses, the former mounted on an Olympus OM-D E-M5 and Panasonic GX1, the latter on a Canon EOS 5D Mark II and Mark I. Different systems, different sensors, different worlds – but if you are interested to learn how these lenses compare then Tyson's review is right for you.
