Was requested to do an alternative review of Panasonic GX7 mainly from a micro 43rd user perspective. Thought it might also be interesting to see how it stacks up to the Olympus E-P5, which is the highest end Pen for micro Four thirds, which GX7 form factor/features pit against directly.
For those who are new to micro four thirds system of mirrorless interchangeable lens system, you can take a look at this website, by far, it's the system that has the most lenses to date as both Panasonic & Olympus bodies can use either brand of lenses (which is >40 now! and still expanding), some are repetitions but nonetheless speaks alot of the format which is the first mirrorless interchangeable lens system that's growing from strength to strength, since 4 yrs ago.
There are several series in Panasonic Series, GF/G/GH & GX.
GF - No frills MFT body, no EVF, no grip.
G - With EVF and grip
GH - Best video capabilities and still combined and grip, GH3 is Splash/dustproof
GX7 is the premium line MFT camera which retains a small enough (and nice looks) form factor with grip unlike G/GH series which resembles more of a mini dslr. It's an upgrade from it's predecessor GX1, as to why there's a jump from 1-7, perhaps it's to show the premium upgrade in features from GF6/G6 to garner this naming. A quick look at the sleek camera!
