Got a bit more time now...in answer to your thoughts, I'd suspect a 500 Mk3 would still be substantially heavier than a 400 DO, although I'm sure it would be closer as the 600 mk3 is now lighter than the 500 mk2.......but at what price point?
As it is, the DO is substantially cheaper than either of the other two, and any mk3 will be priced higher than the current one I'm sure, so you'll have to have deep pockets to afford that one!!
I saw the prototype 600 DO a few years ago when it was at one of the exhibitions, and again that, if/when it comes out , will be a pretty expensive beast.
My main argument for the 400DO is it's weight, I can hand hold it even with a x1.4 extender, and so for capturing action shots it's very adaptable.
Having said that, I'm off to Patagonia and as weight really will be an issue there, I'm just taking my 100-400 with a 1.4 which again works very well with the 1Dx2.
Be interested in anyone else's thoughts, however, and I wonder if the 600 DO might have an R mount?
Hello George hope the spell away was good Funny the shutter noise was the one thing I just didn't see coming,I'm in no way looking to change either camera or lens,but with the type of subjects I oft find myself making images of , shutter noise can have a massive effect on the images I have the potential to aquire because me beasties suddenly know i'm there . Like all things one learns to use it to advantage at times, but i'd adore not having any other noise than what I try not to make.
Fascinating the hear both yours and Bob's thoughts on what might happen with the canon super teles moving forwards,George. Thanks So much for the comeback As I say I'm not looking to change anything,although I am very curious though about how all this will move forwards. So many wildlife togs seem to be shifting to smaller systems,weight is a huge deal as we all get older,but it is anyway. Even with my day job forcing me to be incredibly fit I am really unsure if I could do what I do with bigger heavier glass :mauling a 500/4 lens out to a hare 200yds no cover on me gut might be physically beyond me. The miles I travel on foot after roe, might well also, become a chore with more weight. To my shame I don't really have a tripod ha ha yet... again it's how I shoot that makes having such a good lens to hand hold a joy. try getting a tripod over any form of stubble on one's tummy,it is doable but very tricky it's far more effective being without..if I do my bit naturally
You are right about cost,even though the DO is still a lot of money that slightly lower cost made it just about affordable to me,the 500 f4 ii was really out of reach. I know I'd have gone there but it would have been alot of damn hard work With canon having choice in this 400MM range ie the little 5.6 the 2.8 the cracking 100-400 mk ii I think the DOii will always be bit of a niche lens George,suited to a particular set of needs. It works really for me I suspect because what I do is maybe not so run of the mill . or maybe just more beastie orientated than birdz , it will also appeal to folks getting that bit older and is keeping a few I personally admire going. There is no denying how well it handles, I really thought we would have seen both 500f4 is iii and 600 DO by now but maybe canon are more focused on other things
cheers again have fun in Patagonia oh and show me a couple of piccies when ya come back.please
