Hi guys im a big plane enthusiast and want to be able to listen to ATC convos aswell as taking close up pictures of planes. So with the ATC towers what device can i pick up for 50-100 quid which will allow me to do that and will it need to have the 8.33Mhz split feature as i read somewhere it will?
as for the lens what sort of lens is good for pics about 100-200 metres from the runway? i use an old sony SLR at current.
From the wiki page this horizontal view angle is for a lens just above 85mm.
For an A380 at 100m the angle would be 41deg, so a focal length just less than 50mm.
You won't want the aircraft to fill the viewfinder completely so the angle will be a bit bigger and the focal length a bit shorter.
You'll have to check what you can get for a Sony SLR to cover from perhaps 40mm to 200mm. This may mean 2 lenses. Sony bought out Minolta so you should be able to get Minolta Maxxum AF lenses for your camera or Sony A mount.
There are some 18-200mm lenses for the more recent digital cameras, e.g. Sigma and Tamron but you may need to try them out with a local camera shop to confirm they work with your camera.
