OK, I need a 400mm for doing sports, (motorbikes mainly) and surfing occasionly..... (will use it for wildlife now and then) and I can't afford a 400mm f2.8 L, which is my ideal lens. (I am just an spameture)
Picture quaility is the highest priority, with speed of lens coming in equal second with flexibility.
I have been trawling the threads and other parts of the net and I see there are other options 400mm f5.6 L , 100-400mm f4-5.6 L, 300mm f4 L, Sigma 175-500mm, sigma 135-400, sigma 80-400..... although I have tried a 300mm and it wasn't quite long enough for Bikes due to the best shots being on the corners and the distance you have to be to get the right angle...... also not sure if the 5.6 will be fast enough for darker days....
do any of you have comparison pictures of any of these? ideally against the 400mm f2.8 so I can see how close pic quality is...... (I love seeing pictures
)
I have looked on Pbase and it is very difficult to do comparisons although non of the sigma options seemed to have the pop of the 400mm f2.8.....
I would love to do it for a living one day so my choice is being swayed by this.....
what do you reckon?
cheers
PS I can't really go past £1000
PPS I notice a few of you guys get the 400m f2.8 as presents (:p ) so feel free to give me your hand me downs.......
thats part of the problem....
