Given its price and its size, I am not sure why one would buy this instead of a full frame model. I don't think that the D810 is much more expensive now. The D810 has a crop mode so you can obtain the extra reach if needed but there again with 36MP you can simply crop.I appreciate that if you own many DX lenses it could appeal but even so.
How do you change the card and is it SD or does it relie on built in memory? If so that is a serious disadvantage. but it is probably only going to be used as an ornament behind a glass door. In the Leica video, even the man demonstrating it is wearing white cotton gloves.
It's wonderful and it is art.
This looks very nice but will be 127 on a DX camera sensor if my maths are right. I use a 50mm f1.4 to achieve the same effect on DX and it works very well.We could do with a G series wide angle f1.8 or 1.4 prime for DX. I suppose that it would have to be a 16mm but if it could be done at a reasonable size, weight and price and with hardly any distortion, it would be great.
