Hi ameyam,

For starters there is a section on RCU dedicated to photography
[link=http://www.rcuniverse.com/forum/forumid_352/tt.htm]All Forums >> Radios, Batteries, Clubhouse and more >> Digital Camera & Photo Editing[/link] , not the most active section of the forum, but definitely the first point of call for photography related questions on this forum.

But back to your original question on your choice between the Canon 1000D and the Panasonic FZ38. It all depends on what type of photos you want to take, if you want to only take photos of planes on the ground in the pits either camera would suit your purpose, but if you want to take photos of aircraft in the air you will need a long lens (depending on the size of plane I would say at least 300mm, the longer the focal length the better). Other things also come into play such as the accuracy and speed of the autofocus system of the camera and the high iso sensitivity of the sensor in the camera that will allow you to shoot at faster speeds. I have only scanned over reviews of the Panasonic but it does look like a very capable camera, but I would want to hold one in my hand before I give a final recommendation on purchasing it. I personally use a Sigma 120 - 400 attached to a Canon 7D or 450D for most of my aerial photography and even at 400mm I often wish that I had longer reach (and I am normally shooting giant scale aircraft). The Canon EF-S 18-55 mm IS is a great lens but is not suitable for aerial photography (it is great as a landscape and general walk around lens though). The price of a lens such as the Canon 100 - 400, Sigma 120 - 400, Sigma 150 - 500 or Sigma 50 - 500mm OS is going to be higher than the original DSLR camera and this must be taken into account when deciding on your camera, even if you are going to take some time between purchases.

I hope that makes it as clear as mud

You can seem some of my RC photographs on my Flickr page to see that I am not making this up [link=http://www.flickr.com/photos/pupmeister01/sets/72157623361576518/]Pupmeister RC Flickr[/link]
