I'm torn and not sure if I should be. I currently have: GX-1, EP-2, 45mm f/1.8, 20mm f/1.7 Im drooling over the new 60mm f/2.8 macro lens and the 75mm f/1.8. I'm interested in getting at the very least the macro lens, but will I run into issues if I continue to use panasonic bodies? I'd like to upgrade my bodies eventually, but should my lens selection determine my future body selection? I have uses for all focal lengths and I really like the primes vs the zooms. Does OIS/IBIS only become an issue with low shutter speeds. I'm worried with the longer focal lengths but not sure if I should be.
