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!
