Well I want to get a better primary or back up camera. Actually the 5D MKII is a great camera that I shoot with now. I shoot mostly nature and glamour. I was looking at buying a 5D MKIII but came across a great deal on 5DMK II for 1600 with 300 clicks on it. So I would share batteries etc.
If I buy the 5D MKIII I believe the low light shooting would be better and I heard the A/F also. Just not sure if it would be like 1500 dollars better. Plus I'll have to check I dont believe they share the same batteries.
My current back up is a T2i and I rarely use it. If I had two decent cameras. I could have two different lens on at once...depending on the shoot? If I bought the 5D Mk III that would be my primary.
Thank you in advance for any input
