From Bryan's review on 50D, the 50D has DLA number of f/7.6 while the 40D has f/9.3.


Does this shows that 40D was more versatile than 50D in terms of when using small apertures? Moreover, Bryan mentioned that 50D demands high-quality optics to produce its highest quality images. So 40D allows us to use more range of lenses to produce equally-fine picture as 50D does? (i.e. without requiring L glasses all the time?)


I'm upgrading my camera from rebel series right now, but have a hard time deciding which body. Some says 40D's better, some says 50D's better. I've also looked up to see if AF microadjustment on 50D will be critical to produce sharp images, and whether upgraded 920,000 dots LCD will be essential to have.


Thanks - any responses that helps will be appreciated!
