News Sigma 20-200mm f3.5/6.3 DG

These are all looking decent!
 
I think I will put in a pre-order and give this lens a whirl. If it performs, it'll make a great two lens landscape combo with the 14-28.
 
I'm also of this opinion, a Swiss Army knife as they say here .We were expecting the first ones in stores at the end of September, but nothing yet...

interesting. Seems it's a bit soft in the corners at focal lengths wider than about 50mm. But it looks inconsistent. Some of his examples (in the video) seemed OK, but others terrible. I've seen this sort of thing before with wide zooms which I've usually put down to IBIS effects. Of course, the IBIS is still active (just not compensating for movement) even if the camera is mounted on a tripod.

I guess I'm going to have to get my own copy and try it, but I'm downloading his example files now - all 10GB of it!

Is it a good idea to evaluate the sharpness of a lens photographing tree branches and leaves that can be moved by the wind? Just asking...

It looked a light wind day and shutter speeds were reasonable so I think it's probably OK (but not ideal!).

To my knowledge, IBIS should always be turned off if the camera is mounted on a tripod. That was certainly always the recommendation in my Pentax days.
