Re: OM 50mm 1.4 or 1.8 for my E-520?

Anyone considering using fast legacy lenses on a DSLR should read this link first:

http://www.jayandwanda.com/photography/dslr_man_focus/man_focus.html

The witer points out that the live view sensors on DSLRs have a focusing limit of f/2 to f/3.5, depending on the model, in your case around f/3.5.

Which means that an f/1.4 lens depth of focus appearance in live view will be what the lens would have at about f/3.5. So that the live view will look sharp, but the image may be out of focus.

The link has test images to show this effect.
