Mine will be here Friday! I plan on taking to Mount Rainier this weekend for some Milky Way shots!
I see quite a few people mentioning to check infinity focus. What is the best way to do that? Is it obvious enough to live view focus on stars?
For you and all the others worried about infinity focus:
Dont bother shooting at infinity, use hyperfocal distances. Set hyperfocal distance on this lens by putting the infinity mark over the number of the aperture you are using and you'll be at the hyperfocal distance. Everything from half of the hyperfocal distance to infinity should be in focus.
Google DOF Master to find charts about what these distances are for each of your lenses so you'll know what your nearest point in focus will be for each aperture and focal length.
Remember, you wont see this thru your viewfinder or live view as your aperture is always wide open unless you press the shutter or the DOF preview button.
Or, can someone who has this lens and understands hyperfocal distances confirm that the focus scale is also not accurate for this?
