It is time to get on and just take pictures. No more deliberations or trial runs.
One last word regarding the Panasonic G6, it IS an excellent camera and I do recommend it wholeheartedly.
There are small compromises, which, if you are upgrading from a point and shoot, bridge camera or previous micro four thirds model, will not apply, and you possibly wouldn’t notice.
The compromises will be in the low light performance – the amount of image degradation and general quality when there isn’t a lot of available light, although this can be negated to a large degree by using a fast lens, may be the Olympus 45mm f1.8 or Panasonic Leica 25mm f1.4 for instance.
There may be other compromises, in dynamic range – how well the sensor balances the bright and dark areas, colour representation (I found it bloody good) and general image quality in comparison to an APSC or full frame sensor cam. Again, in good light I really could not find flaw.
I personally have decided to stick with APSC for now, As a portraitist this format offers me the bodies, lenses and other accessories at reasonable cost, to try and make the best of what I call my hobby.
The biggest compromise for me with this particular camera would only be depth of field control, the amount, and quality, of out of focus areas in an image.
Portrait often relies on this for creative purposes and the m43 format makes it a tad more difficult (or expensive) to achieve.
For you, it could be the perfect camera.
