sharp knives matter

Just some sharpness testing of the Canon EF 70-300mm IS USM, shooting at 70mm.

I'm quite surprised by the sharpness at f/4, I would have thought it would be a bit softer there... on the other hand, at f/20 and over, it gets quite horrible - lucky I don't shoot very often at those apertures. :)

All that money on a sharp lens... then take a snap of frosted glass.

On April 29th I started my day at 2:45 am. I drove with three friends to a lek in Southern Alberta. We had to be in the blind by 5 am. It sure took a long time before there was enough light to take photos. We could hear the grouse. They were making many sounds and we could see their outlines in the dark. It was another great day. The last time I was out there was two years ago.

I was using a brand new camera so I had many photos to delete and of course far too many photos over all. Most photos were only cropped. I didn't adjust any colors. Some photos are not even cropped.

Thanks for your visits and comments. They are all greatly appreciated!
