This is such a smart camera. I've had two weeks with it now, and it doesn't do everything, but it does what I want. And it does what it does very well.
I've only just received my two autofocus lenses for it, a Sigma i-series 45/2.8 and Panasonic 20-60 f/sad zoom. The Sigma is definitely the lens that the camera was designed for. I was torn between it and the 50/2 from the same family, but am glad I picked the smaller lens. The zoom is light but bulky – so many people called Panasonic's camera and lens brand "lummox" that I stopped correcting them – and not a great aesthetic match, but I think I'm really going to like it. I'm not a zoom person, but one of my abiding regrets was selling my Olympus 11-22 for 4/3, and this has something of the same feel.
But the BF: such a smart camera. It's set (inherently) for wide-area continuous focus, which has no problem tracking tulips blowing in the breeze. Half-press the shutter and I can immediately use the control wheel to change exposure compensation – it won't show anything as uncouth as a histogram, but lets me choose the colour and exposure value for zebras. And, shutter half-pressed, if I want it to pick a different focusing area all I need to do is press the up or down equivalents on the control wheel for it to jump from place to place. It also lets me choose the colour for focus peaking, which I have set up for my MF lenses, and works to confirm focus with AF lenses as well. (I chose magenta, since purple is a fake colour that doesn't really exist.)
Downsides?
Unfortunately the screen really is as hard to see in bright light as all of the reviews say. But I'm old enough that I have a Hoodman loupe around here somewhere, so I might get it out again. It's also going to be very difficult to find a wrist strap that's pretty enough for it. I'm using a Gordy strap right now, but have my eye on an A&A silk strap when the bank account has recovered somewhat.
And boy howdy, I thought there had been a terrible mistake when I saw the prices of the spare battery and external charger. It's a good thing I think I'll only need the two new lenses for it.
One really slick feature is the ability to transfer images directly from the camera to a USB stick.
So many reviewers and commentators seemed obsessed with the 'lack' of an SD card. People fretting about not being able to switch out cards during a trip, or having the redundancy of dual cards – all those problems, magically wiped away.
