Try a Sony USB cable? I’ve had instances where 3/4 did not work. Many phone cables etc really aren’t made for the necessary data transfer.

I can't connect it at all either on Windows 7 or Mac, with different cables all I have "USB Device not recognized" (it reports no hardware ID to install a driver). I've tried to contact the support as I bought thru official store but they haven't answered in a month, sigh...

Verbatim micro usb cable is the one that worked for me. I have a few different micro usb cables that came with various items that I bought and at least one or two did not work with my PC and Techart dock but generally all work just fine for charging stuff.

I found out today that with the TZE-01 Voigtlander lenses report the correct focus distance and you can find that in the EXIF data if you use exiftool and look under -focusdistance. I wonder does anyone know if the Z cameras use this information for 5-axis IBIS.
p.8 #4 · TZE-01 Owners Unite! Images/Evaluation Data for Techart Sony E > Nikon Z Autofocus Adapter / image picture pictu
Important to note that only the most recent CV lenses have the distance encoders to correctly report the focus distance. I believe just the 110 and 21/1.4 qualify.
One way to test would be to mount on on the TZE and set the non-CPU information to 110mm. (The non-CPU won't be used while the TZE is active.) Make sure IBIS is on. Focus on something, zoom to 100% magnification, and observe in the viewfinder how much jitter there is while handholding. It helps to lie down to have a steady posture for a minute or two. Then, slightly dismount the lens, breaking the electric contacts. Now the Z will fall back on the non-CPU information.
If the TZE is providing 5-axis IBIS, then there should be a little bit more jitter for some types of motion. It may be hard to tell for sure though, 3-axis versus 5-axis isn't a big jump.
If the TZE is not actually providing good IBIS (I posted earlier about this), then there will be much LESS jitter in "dumb" mode.
I checked the EXIF information from my Loxia 25mm (which doesn't have a distance encoder) and it ALSO has information in the Focus Distance field. Unfortunately, every photo, no matter the actual focus distance, is recorded as .63m. That could explain why IBIS was audibly engaging on the TZE, but failing to provide any benefit--the Z might have been acting on incorrect distance information. If I still had it I'd try testing it focused at .6m to see what happens.
I'd be very interested if the CV 110 and 21/1.4 have perfectly functional IBIS on the TZE--I sent mine back because I need IBIS more than EXIF information and focusing aids. I'd consider rebuying it for the 110 though, especially if 5-axis IBIS does work.

I was using the Voigtlander 65 f/2 APO and it correctly reported the distance and the focal length and you can't select 65 in non-CPU information (I set it to 70 with the CV 65), so the adapter is definitely working with this lens to supply the right focal length and to code distance information in the EXIF. That is all the information the camera needs to provide 5 axis IBIS, the question is whether the camera actually uses this information for 5 axis IBIS or falls back into 3 axis IBIS.

There are lots of micro USB cables sold that are charge-only - they're missing the wires for the data lines inside the cable.

You're right, it looks like CV started putting in distance encoders earlier than I thought. Maybe all E mount CVs have them.
There is, unfortunately, a third possibility--that the Z, despite having correct information for EXIF, isn't using it for IBIS successfully. That's been the case for Dandelion chipped lenses on the FTZ and the Loxia 25mm on the TZE. I'd be very interested in hearing more IBIS test results from the TZE.

I believe all the CV lenses for Sony E mount include distance encoders and I think it shows up in the EXIF data. I know it does for the CV 65 f/2 APO, but haven't checked others. Interestingly even though the Zeiss Loxia lenses are manufacturers by Cosina they do not include the distance encoders, so no surprise you only get 3-axis IBIS and no adapted lenses with the FTZ can use 5-axis IBIS. I think the CV lenses for Sony might be using it, however. I wish someone would test and see if you do or not.
p.8 #9 · TZE-01 Owners Unite! Images/Evaluation Data for Techart Sony E > Nikon Z Autofocus Adapter / image picture pictu
Even worse than that...the IBIS simply wasn't working correctly on the TZE. Same with Dandelion chipped lenses on the FTZ. I'm not sure of the reason, but it may have to do with incorrect distance information. It's plausible at least. With non-CPU information I can get 3-axis IBIS, but enabling that requires disabling the TZE's functionality.
That's why I'm curious if IBIS even works at all with the distance-encoded CVs on the TZE.

Well, I have both the TZE and a dumb adapter so I will test if the TZE works as well as the dumb adapter or maybe even a bit better with the Voigtlander lenses. I was under the impression I was getting 3-axis IBIS with my Loxia lenses and the TZE, but I will check that as well. I won't be able to do the tests right away, but I will before too long.

Interesting point. I've been generally satisfied with my 24GM on the TZE, but I just was out using the FE 50/1.4 and the results were inconsistent. It seems to struggle more with AF, but there were some shots that should have been nice and crisp given the shutter speeds,wherever the actual focus point ended up, but that I struggled to find anything in sharp focus. I wonder if the IBIS was somehow contaminating the results?
p.8 #15 · TZE-01 Owners Unite! Images/Evaluation Data for Techart Sony E > Nikon Z Autofocus Adapter / image picture pictu
Well I'm now less certain, I was using the CV 12/5.6 in E Mount today and I'm definitely seeing drift in the IBIS. Seems worse with wide lenses. Now that I see it clearly, feels like I've seen it some with the 21, less so with the 40mm. If I set Non-CPU to 13mm (there is no 12mm) and rotate the adapter to break the connection, IBIS is much more steady. Additionally there are a couple shots at 1/100 that seem to have motion blur. With functioning IBIS and at 12mm that shouldn't happen unless IBIS is inducing some motion...
As far as EXIF, on the 12 it show Subject Distance Range as "Unknown", same with the 21mm f/1.4. Don't see other Focus Distance fields other than Hyperfocal distance which I'm not sure what to make of other than it varies with focal length and aperture.

I didn't see the distance until I used exiftool either. When I did under -focusdistance, it gave me the same value that showed up on the top LCD. Do you see the focus distance indicated on the top LCD? I do with all my Voigtlander lenses, but not with my Loxia lenses.
If the TZE screws up IBIS so that it is worse than the 3-axis you get with the dumb adapter, then I will probably forgo EXIF data and just use my dumb adapter for now.
p.8 #17 · TZE-01 Owners Unite! Images/Evaluation Data for Techart Sony E > Nikon Z Autofocus Adapter / image picture pictu
I was using RAWDigger. Does exiftool have other info? I don't use that enough, would take me a little bit. Could send you RAW 12mm and 21mm files if you want. But that said, no I don't have Focus Distance on my top LCD? I get SS and Aperture, Drive Mode and ISO.
I'm on the fence. For just EXIF I'd agree, but you'll lose the MF focus confirm as well with a dumb adapter. Not so useful on a 12mm, but on a 40/1.2 it's great...

Yeah, I would hate to lose focus confirm as I think it is really useful. Hopefully TechArt can get this sorted out. If you want to send a couple files to me I can check them on Exiftool. Just shoot me a PM and I we ought to be able to figure out a way to send them.

After checking some of Mathieu18's files and some more of my own, it seems that the TZE is recording the focus distance in the EXIF data of all shots as .63M regardless of the real focal distance and it is doing this for all Voigtlander E mount lenses. My guess at this point is that IBIS will work pretty well if you are close to this distance, but as you move away from it IBIS will begin to mess up.
p.8 #20 · TZE-01 Owners Unite! Images/Evaluation Data for Techart Sony E > Nikon Z Autofocus Adapter / image picture pictu
Anybody have a decent contact at Techart? Seems we need to get them to plug-in whatever data they get from a Loxia in to all lenses regardless. It’ll break 5 axis but better than this drift.
