I've seen results from that 300mm f2.8 and they've been pretty impressive - and of course there's a new 2x converter that will add a whole new dimension to it. What they always lacked was a slower, more affordable longer telephoto. One big plus for those with the eyesight and ability to use manual focus is being able to use lenses of almost all fittings with an adaptor. At least you keep metering unlike other brands.
Taking time to sort out a whole load of folders of photos taken earlier in the year. I tend to take out the ones i like most at the time and play around with them amd leave the other, non blurry, ones to go back to and either process or delete later. Now, I know the weather was with me in late summer, but those last E-510 shots look really good! OK, I admit the 40D ones taken in the same conditions also look good!
