Magic, simply magic, or simply "with most of my own CPU-modified F lenses," Birna's touch, which amounts to the same thing in this case. Magic is a scientific explanation when you understand as little about optics as I do.

"Any sufficiently advanced technology is indistinguishable from magic" - Arthur C Clarke.

The Voigtlander Z D35mm f/1.2 Nokton looks like the perfect companion for the Zfc. Go for it, Kenneth !

Happy shooting.

Well, I don't have a green dot, but i have restored smooth as butter focusing! In frustration I separated lens, adapter and Z mount, gave them "a good looking at" and reinstalled the Contax, adapter and Z mount, and voila, smooth as butter focusing again.  Hands on science! Simple as putting the screwdriver in the screw slot or whatever.

The Voigtländer 35/1.2 does tolerably well close-ups, thus adding to its versatility.

Since I prefer small lenses on the Z fc, I signed up for an early bird-offer of the forthcoming Viltrox 13mm f/1.4. Hopefully it'll arrive later this summer, in time for floral abuses :)

I had similar offer on the new Viltrox 13/1,4 like a 20mm f2 coverage on the Zfc .

Has anyone tried the Voigtländer 23/1.2?
Seems like this would be a nice combo with the Z fc as well.

I have the Viltrox 23mm f/1.4, so dropped out on the Voigtländer.

Apparently there is a new generation of excellent optical design for small, high-performance lenses available. Thus many of the reputable makers launch useful products at present. There is the occasional lemon, like the Zhongyi/Mitakon 85/2.8, but fortunately these are the exception not the rule. Of course, if price is very modest, one has to except less than stellar performance.

Birna, is this little lens labeled a 11 or a 111 model Nokton?  It sure is difficult to find it in Canada.

Available about fifty kms from my home!  No more excuses, money up  or shut up now.

Birna, how do you configure the Z fc to use aperture ring on lens when using CPU lenses?
I find that any CPU F-mount lens (AF, AF-D, manual with CPU added, on FTZ II) requires setting the aperture on the lens to minimum and using the front-dial. The Z fc gives an FEE error otherwise.
On the DSLRs, there's a custom setting (f7-Aperture setting) to control this, but I can't find the same on Z fc. Also the FTZ II manual says to set to minimal as well.

Thanks!
BJ

It may in the controls section of the menu. I vaguely remember there being a setting to use the aperture ring, or a control dial.

There is no traditional "aperture follower" on the FTZ/FTZ II adapters. Thus, they act as a camera being locked into "G" mode, i.e. aperture is controlled by camera dial(s). If the lens has a CPU. it will  be used in "G" mode too.

As a consequence, the aperture ring on the lens should be locked to the minimum value.

An alternative is to keep the small sensing tab on the FTZ permanently pressed in. A small piece of wood (tooth pick) or similar in combination with epoxy glue will solve that issue neatly. An advantage is you now can observe depth-of-field and bokeh at apertures wider than f/5.6. The disadvantage is that you need to have the camera aperture figure to that value or larger, or a wrong exposure will result.

Thanks Birna, that makes sense to me now. And explains why the custom config is "missing" on the Z bodies.  ;)
