Advice - Long Lens for Airshows (Nikon Fit) 300 or 400mm?

[jj2908]

Can I get your advice please?

I have a Nikon D5100 which I use on AE or P mode normally. I've just bought tickets for two days at RIAT which should be good being the RAF 100 Yr celebration.

My question then - what telephoto lens for the competent amateur? Ive a good wide-angle for static displays so Im talking specifically about telephoto. I see there are plenty of tamron and Sigma lenses at the 300mm max focal range for way below £500 but I wonder if it would worth investing in a 400mm with the associated price jump?

Advice gratefully received

Thank you everyone for your comprehensive replies and advice and to eltawater for the 'go big or go home' summary. My amazon shopping bag now has this sitting in it... waiting to see if any price reduction or deals pop up before RIAT
