Hi,
I upgraded to the 5D3 this October and since then my 7D has been gathering dust. I thought that I would use it for birding pics with the 100-400 mm, however, I tried the 100-400 with the 5D3 today and found shooting to be considerably easier with the improved AF without any loss of IQ.
I also own the 70-200 f/4 non-IS. Now I am pondering whether I should sell the 7D and the 70-200 f/4, put in some more money and buy the 70-200 f/2.8 IS II. In the alternate, I could sell only the 7D and buy the 135L. Any suggestions?
I don't think that I'll need the 7D for any other purposes. Don't have any EFS glass so no downside there.
I normally do portraits, street photography and occasional landscapes.
