Hi guys
I've been out of action because carrying my 400mm DOII/5D on a BlackRapid has caused painful hip problems. I reckoned that a double-holster to spread the weight over both shoulders might solve the problem (after some rest from carrying). Not wishing to spend £150 for a double BlackRapid I paid £6.49 for a Chinese knock off, which I tested with two 14lb weights. Problem solved and I am back in business!
By mistake, I took out yesterday the 400mm + 1.4xTC attached to the 5DIV instead of the 5DSR - I usually use with a 2xTC on the IV. But, I really liked it and will use this combo for a while. It's very responsive, very consistent focus and sharp. Here is a juvenile robin very close up, which probably would have given Moire with the 5DSR and some shots of a great crested grebe quite far away catching a giant crayfish, where I used higher speeds than with 800mm.
I couldn't resist posting this banded demoiselle - the minimum focus is 3.3m with the lens, not exactly macro, but it is so sharp it works.
