Ta for all the replies to my last post, I also wanted to add the following :
I agree that on top of a 5Dlll a 24-70mm f/2.8L + 70-200mm f/2.8L IS, that a 100-400mm will be too heavy to lug around, so also considering a converter. With the 70-200mm what recommendation would you make : a 1.4XII or 2XII or 1.4XIII or 2XIII ??
Tilt shifts might be a little out of my range, but Im also considering some primes as well - still learning with these, so would love some advice on what range would be the best : 35mm f/2, 50mmf/1.4, 85mm f/1.8, 100mm f/2.
I travel a bit & shoot mainly landscapes, street shots, architecture, people shots etc
