I was configuring my bag the other day... I tried to stuff the GH3, 7-14, 12-35 and 35-100 into my Think Tank Retro 5 bag. They fit snugly. On the average, I use 7-14 for about 10-15% of my total shots, the 12-35 gets the most use, followed by the 35-100. And I use the 7-14 mainly as 7mm or sometimes to the other end at 14mm. Relatively speaking within the Micro 4/3s system, the 7-14 has its own share of weight and bulk. (I know how a 14-24 or a 17-35 weighs in Nikon , I'm just spoiled with Micro 4/3s I guess?). How I wish there is a native rectilinear ultra wide angle prime. I was thinking even a 10mm 2.8 would suffice, but a wider one will always be a welcome. Do you want one? What do you think?
