Re: suggest manual lens for milky way

I don't quite understand this. You would normally shoot in M mode (manual) once focused there is no need to focus again usually. Not sure what you mean by changing AF modes.

You need to keep the camera lens a bit warmer than the ambient air in cold weather otherwise it will fog up. You can do this as simply by putting the lens in your pocket for a while.

I use a bit of insulation wrapped around the lens before I go outside and that prevents heat loss and delays fogging up. You can also get chemical heat pads and wrap them on the lens and put some insulation on 2nd if fogging is really bad.
