Have you bought a new lens ? Or have you changed your post-processing ?

I changed my camera in a few months ago from the Canon 10D to a 40D.
Although the 10D had served me well for over four years I needed the extra
buffer capacity, speed and pixels of the 40D. At the same time I ordered a
300mm f2.8 (and a 1.4 extender). This new lens is so sharp that it still
amazes me but the great advantage is this set-up is that I no longer need to
pan and zoom at the same time (as I did before with the 100-300mm). I still
use the zoom for the Hercs and the Andover here but even with some severe
cropping the 300mm fixed lens gives better pictures (and I never will get
used to a 'trombone zoom'). The exif data is left in these files by
Photoshop CS so if you download a file to your desktop, right click on it
and select Properties/Summary/Advanced all will be revealed.
