As wrote in another Olympus forum I am using Olympus DSLR for a long time. Today I use E-1 with 14-54 lens plus 40-150 mk. 2 and 35 Macro. Used to own also E-520. I was reading a lot about the Micro 4-3 but never decided to join in. I have checked the Olympus offers and the E-P3, E-PL3 and E-PM-1 are very nice but without a viewfinder and an aging sensor. The OM-D-E5 seems great but way over priced in my opinion. So are the Olympus Micro 4-3 lenses. This made me look deeper at what Panasonic has to offer, I checked their cameras and lenses. I liked a lot what the Panasonic G3 offers and the price is very attractive as well. I also read about their lenses and most of them have very good reviews and their prices are not too high. How good is the G3 in practical use? How good is the IQ? How good are the Panasonic lenses? Will I feel a big difference from my good old Olympus equipment? Any comments based on your experience are welcomed.
