I know automatic exposure won't be available for instance. But what about automatic light balance? Will it work in mixed lighting conditions? Or with a light balance preset? Any advice on using that lens on digital bodies? I plan on using it for table settings and the x1.5 crop should make it just right. Even if Photoshop can now correct perspectives quite well, I guess that it's a plus to be able to compose the image right. But of course I'm aware that there are some trades, especially the lack of exposure control. Any experience you would share?
