Stuck WIth The 50D?

I'm having no luck selling my EOS 50D which I bought from LensRentals last Summer and which has over 113,000 shutter actuations.

So, I decided to get it back out of the box and play with it for a bit. It's snowing this morning and there have been a couple of pairs of Northern Cardinals hanging around the feeding area. Here are photos of a malee and female, cropped so they are approximately the same size in the frame. I had added the 1.4X extender to the 300mm lens prior to the second photo so the first is cropped more. Also, the shots of the male were underexposed by about 1/2 stop so I increased the brightness when converting to JPGs.
