hi forum
i am currently looking to add to my kit, i am a member of the local gliding club and therefor would like to photograph the aircraft we have based at the field in action.
my current superzoom today demonstrated very well it's failings in the AF department when trying to track fast moving aircraft. in this case models. so it's time to agrument my long suffering and miss used 18-270. just need some thoughts from you guys. ideal budget is $2000 - 2500 aussie. few ideas i have come with are as follows
Nikon 80-400 VR, will my d90 be able to drive it fast enough for aircraft ?
nikon 300mm f/4 + kenko 1.4 tc
sigma 100-300 f/4 + kenko 1.4 tc
sigma 50-500 OS
i don't need a lens the is "fast" in terms of f/stop as it's main use will be daytime and the skys down this part of the world are normally nice and sunny. even at f/8 the tamron was great when it locked on focus, exposure was quite good, shutter speeds were constantly over 1/600 ranging to 1/1000 and higher. i did consider the 70-200 f/2.8 vr II, but i figured that once i started sticking a 2x tc on it i would loose too much image quality, could be completly wrong here, and that combo is really starting to streatch the budget
any input would be fantastic
