Sent in my 30D to canon which the shutter button stopped responding this week, and after reading multiple threads and topics on upgrading I decided to go for it. My oldest son plays basketball year round and the 30D has served me well, I am hoping the 50D paired with my 85MM 1.8 will help me in the poorly lit gyms I deal with all the time. If the 50D is just a little bit better in low light I will be happy. and if the shutter button works also.
