Hi everybody, I have been following with interest the discussions about the Canon 100-400mm zoom lens, and how different examples seem to be softer at the edges, etc.
So now I am about to go out and buy one, but I need some guidance on exactly what to look for, and the best ways to make sure that I get a good one.
My initial thoughts are to take my camera and notebook computer along to the store and take some shots at various focal lengths (100, 200, 300, 400) and aperatures Wide open, f/11, f/22), then copy the images to my conputer, and look at them at 100-200%. Them repeat with each example that the shop will let me work with.
OK, so far, so good. Sorry, this post is getting long...
Where i need help is in what is the best thing to take the photos of, and how best to exaluate the images.
Anybody care to offer their thoughts?
Many thanks, ...David
