Thanks for the rundown studiodc.
I'm trying to decide between the 12-35 Panasonic and 12-40 Olympus. I'm trying to fill in the pros and cons of each. Both sound like great lenses.
Panasonic 12-35mm $700:
Pros:
Stabilized
Smaller
Lighter
Comes with a $100 Adorama gift card
Cons
A little soft at 12mm (is it acceptable for Astrophotography?)
Fly by wire manual focus
Olympus 12-40mm $700:
Pros:
Good 'Manual' focus option
Sharper at 12mm
More zoom
Cons
Not stabilized
Not auto corrected on GX85
Heavier
Or maybe I should just get a 14-140 super zoom and some primes. I'm spoiled for choices!
