The 40D is an excellent camera and apart from some cosmetic changes and the MP boost is almost identical.
The XXD series of cameras have been a mainstay of many users here and elsewhere and can be highly recommended.
I'd grab the 40D and use the extra cash on glass...

I agree 110% with Dazz - solely for aviation the 40D is more-than-capable and the extra MP of the 50D would be barely noticeable. Spend the saving on glass, if you don't already have permium lenses.

Quoting Stef247 (Thread starter):
is the eos50d mutch better than the eos40d

In one way it is and in another it isn't.
The 50D is one of the camera's I have and to be honest the least pleasing and to be real honest I like my good old 20D more then the 50D but that doesn't make it a bad body.
You have to do some reading to understand I am afraid.
Start here(diffraction):

The 50D diffraction kicks in around F/7.1(maybe even wider).
Many spotters like to use a Canon 100-400 for example which has a sweet spot somewhere around F/8 - F/11
and already the problem becomes visible, the 100-400 isn't good enough to make the 50D shine.

A diffraction calculator can be found here:

As said this doesn't make it a bad camera but it is a camera with limitations.
If I know in advance that I am going to need big prints I"ll happily use it but only with glass of F/4 and faster.
And if you can live with these limitations and are prepared to invest in expensive glass you will have a cracker of a camera.

It might be worth to wait for the 60D though as it has been rumored to have extra computing power to combat diffraction.
Something I expect to be present in most next gen camera's because a resolution limit has been reached with the 15mP APS/c sensors and because diffraction is not some sort of magic fixed number like the speed of sound.
There are ways to fight it, even USM works to some extend albeit at the cost of extra noise.
So I am kinda curious to what Canon comes up with.
The truth lives in one’s mind, it doesn’t really exist

I'd go with the 40D. Recent another A.netter and myself had the same question. We both ended up going with the 40D. You can save a nice amount of money and get the same camera essentially. That's my 2 cents.

Yup I agree. Grab a new 40D now while you can. I also chose the 40 over the 50D. I did some research and found many testimonials similar to Willem's above.

You might want to run a search of the forum as this has been discussed several times with some quite detailed posts. For example; 40D Vs 50D (by Calfo Mar 1 2009 in Aviation Photography)

Equipment: 2x Canon EOS 50D; Sigma 10-20 EX DC HSM, 50-500 EX APO DG, Canon 24-105 f/4 L, Speedlite 430EX

Not that this is particularly relevant but I still use a 30D and find that actually better than the 40D........
