Testing a new lens

I've been testing a new lens. I don't like zooms -- they are

generally slow and heavy. But this zoom lens is (stuck at) f/2.8 so

it's not that slow. And it is very sharp; that fact can make up for

the weight which is substantial. It's the heaviest lens I have ever

used, I think. We'll see how much I use it or whether I keep it for

that matter.



The lens is clearly good for birds out my back window. This junco

turned his back on me and I got a decent shot of his tail and back

feathers.
