First of all, I apologize for a late reply, I've been both ill and busy for the past couple of days.
Yeah, I recently learned about the Ricoh GR cameras and they really seem interesting as a "no-frills, just got out and shoot" kind of camera.
I am quite pleased to see more cameras like that coming out, like the Fujifilm X1000VI, even if they're a bit on the expensive side (let's not mention the Leica Q3).
I concur. But I wish there were slightly cheaper alternatives, even if I understand why they hold their value so well. Check out prices of used GRs on mpb.com or some similar site, and you'll see that they are barely, if at all, cheaper than new ones. I mean, there aren't too many large-sensor cameras with a good lens and compact size.
All of that being said, I can't stop dreaming about a GR, a Fujifilm X70 or X100 series, a Leica X1/X2, or even a Nikon Coolpix A (which was, according to my research, sold basically nowhere, as I can't find almost any for sale). Yeah, I know there's Sigma's compact cameras, but I've heard Foveon takes skill and patience. So far the best alternative I have to those APS-C sized compact cameras that I lust after is my Olympus Mju I (now I even have two, heh), but that's a film camera with automatic exposure, and as such, it's a very different experience.
I can't comment on most of these cameras, but from my experience with the D7000/Z9 I can say that an FTZ II on any Z camera is unlikely to be worse than the same lens on a Nikon DSLR. I had some
amazing results with my 200-500mm FX and still use my 18-300mm FX, the only noticeable issue is they keep the lens 'awake' more than a DSLR, so may cause premature wear on the VR system.
Thanks for the input. Maybe the FTZ adapter that my friend bought is faulty, or it could be that she's expecting too much from it. Either way, I'm not discarding the FTZ route just yet. But I am starting to think the Z6 is worth the extra money, even if the XQD cards are kinda putting me off; they are formidably expensive, and so are the readers.
