Humberto - re advice on longer zooms: I have the Nikkor 50-300 4.5 which is a really useful lens. I've not used the Sigma. I also have the Nikkor 80-400. Of the two, I favour the 50-300 - it has greater zoom range ( 6x vs 5 x) and mine is par focal. Depending on the individual lens they can be decently sharp - mine resolves 140 lp at 300mm and the build quality and all-metal construction are in its favour. I find critical focussing with the 80- 400 much harder, although it is pretty sharp. I also have a number of 300 2.8 primes ( both Nikon F mount and PL) and a 500 f4 - but I find I use them far less often because of the time involved in the lens change.
I haven't used the 50-300 with an extender, so can't comment on whether it fits, and would probably go 500mm or 300mm plus x2 if I needed the extra length.
Thanks Mark, The problem on 50-300 is that 300mm is not enough for me, I thing until I have money for a 500mm or even a 300-800mm will have to buy a sigma 50-500mm, I,m filming with a sigma 400mm f/5.6 (old one and very cheap) and the images are good, at 2K is a bit soft, but probably in 2K will be soft with every lens...
