I have high hopes the EM-1 comes to us with much better video than on previous Olympus bodies. If so, that plus the possibilities of using 4/3 glass like it's native (fast phase detection a/f) gets me excited especially after seeing the kind of quality and character coming out of their older lenses. I'm thinking of keeping my GX1 and eventually going GX7 for light weight duty (maybe just keep a 20mm and the new 14-140) and for high qaulity shooting + video I won't might the extra weight of the new EM1 + bigger 4/3 lenses especially with outputs like these (First 2 or 3 below would be my (big) kit for EM-1, PLEASE good video on it =p): Olympus 14-35 F2.0 (This may let me toss all my other primes) Flickriver Olympus 50-200 F2.8-3.5 (A lot of reach + fast) Flickriver: Photos taken with Olympus Zuiko Digital 50-200mm f2.8/3.5 lens Olympus 14-54 F2.8-3.5 (Versatile) Flickriver: Photos taken with Olympus Zuiko Digital 14-54mm f2.8/3.5 lens Olympus 35-100 F2.0 (Too big for me but quality is outstanding) Flickriver: Photos taken with Olympus Zuiko Digital 35-100mm f2.0 PRO ED lens And many others! Olympus Lenses: Most Popular, Prime, Zoom etc. - Flickriver Lens Explorer Database of 4/3 lenses and stats: Four Thirds | Four Thirds | Products(Lenses) Too bad flickriver didn't make a Panasonic listing of lenses =(. I figured I'd share this finding since not sure a lot of folks here are too familiar (like myself) with the 4/3 world and what the forthcoming EM-1 potentially brings to the table.
