Going to be doing RIAT this weekend and a Farnborough corporate day next week, tempted to hire a TC for my D70. I currently have a 70-300 5.6G Nikon lens which I found just a little too short on previous airshows.

Will that lens stand up to being used with the TC 1.4x ? I'll assume it'll be nice and sunny, but obviously the 'G' lenses are low budget, so worried that the images will not be clear or that it won't fit or something..

I wouldn't recommend a TC for f5.6 lens. It'll be a f8 lens, then AF probably won't work, together with a darker viewfinder. I don't think it's really worth it.

As Gemm says its really not worth it... If you have a faster lens then yes it would be better.

However you will loose autofocus for definate and as mentioned your viewfinder will be darker therefore less easy to focus.

I dont know if you've ever tried tracking a moving object with manual focus on a digital slr... Its not easy at all, your hit rate of in focus shots will be extremely low.

For the future if you go for a long lens look at something like the Sigma 150-500 or even the 50-500 (though this is a big heavy lens). You can pick the 150-500 secondhand for a good price these days and it has perfect focal length for an airshow.

I'm tempted to rent a 50-500 or a 150-500 now! But that's £100.. and as you say the lens is £500.. decisions, decisions! scratchchin
