I mostly use the Oly 12-50/3.5-6.3 (because of the macro feature), the Oly 75-300/4.8-6.7, the Oly 45/1.8 & the lumix 9/1.7 or sometimes I just carry the Lumix 14-140/4-5.8 and forget to take the other lenses.
I would love to get the 50-200, I got to try it a couple of times off a friend, it's nice.
My coworker uses both Oly 12-40/2.8 and 40-150/2.8 with his G7 in his video work, I haven't had the guts to let try either one of those 2 lenses.
Have you used the Lumix 42.5/1.2 or do you just prefer the Oly 45/1.2 Pro?
How do you feel about the Oly 12-100 f4?
Can't wait to see your images.
