First paid shoot with EM-5

They are very nice in general-- the main thing for you is to be sure get a proper exposure. The shots taken with -0.3 EV suffered, and you had quite a lot of shutter speed to play with-- some were taken at 1/320th, you could have gone much lower to get a better exposure.

The higher ISO value didn't seem (to me) to be a problem-- its just under-exposure (even slight) that makes everything look bad!

I have similar problems with my E-30 if I'm not careful!
