Yes, the Leica glass is amazing but so it the Zeiss. I found the hard way that the D800 and manual focus was very unforgiving. I ended up with a D4 and kept all my Zeiss glass. They perform very well and focus is tac sharp. Personally, I find the only advantage of the M is in size. I have had many M's and Leica glass and found that they needed service quite regularly. The slightest bump to the camera would throw the RF off. In the end, I am 100% SLR now and have never looked back.There have been a lot of comments about how good the ZF lenses are. My needs are a bit different than many on the forum as I do commercial and documentary work, My documentary work is often under terrible lighting which demands good performance at maximum aperture. When I purchased the D800 I bought a 25 f2, 35 f2 and 100 f2 ZF set. I wound up sending them back seriously disappointed. Stopped down to f8 they were good but anyone cam make a lens that produces good images at f8. I need fast glass and f8 won't do it. I wound up sending it back to B&H and bought a Leica M9. I already had current glass, 25 Elmar, 35 Summlux FLE, 50 Asph Summilux, 75 Summilux and 90 apo asph Summicron. The Leica glass performed amazingly well wide open but have spent nearly a year getting my new M9 straightened out. In the end most of the lenses had to go to Leica for shimming and calibration and my 90 is back again. The M9 had to have a new sensor, mother board and one other board. Sad for a new camera and three new lenses. Anyway I think the M9 will be a great camera for my work but the DF will be a great addition too. It has such spectacular high ISO so all I need to do is put together a few good fast lenses and I'm in business.
I do some hard core work, see attached.
Your street work is impressive.With the exception of a few AF shoes most everything is manual focus Zeiss or Nikon glass.
