I find it odd in a way that whenever the Canon 40D is compared to the Nikon 300 in reviews, the 40D always ends up being the " recommended " camera.
Here is a quote from one such review ....
But given the Canon's excellent performance in the things that count, we'd call the match differently. The D300 surely gave us the most bang. But the EOS 40D gave us the most bang for the buck!
I did note the Nikon has a higher frame rate 8 fps to Canon's 6.5 fps -IF- you purchase the accessory grip. Without the grip the Canon is 6.5 fps to the Nikons 6 fps. The Nikon goes up to 3200 ISO where the Canon tops at 1600.
Sounds like a tough choice, I use the 40D and lately have been doing a lot of photography of the moon through a telescope.
Sounds to me like the pro's are saying the Canon is the better value.
For the price of the Nikon, you could opt for the 40D and get a real nice lens to go with it.
But you know how it goes, on here the Nikon fans will recommend Nikon, and Canon users recommend Canon. But when it gets down to reading reviews it seems the Canon is the recommended choice.
Oh by the way, before I purchases this Canon 40D I actually went and looked closely at two Nikon models ... the D80 and the D300. After all the hype I read on here about Nikon, I figured what the heck - I got $2,000 budget and it might be time to make a change.
I opted for the 40D, in my mind the Nikon D300 did not bring enough to the table to warrant the cost.
So I came home with the 40D, 28-135 IS, and a another 580EX flash unit.
CONGRATS to the OP of this thread in his excellent choice !!!!
