Nikon Z7 with TechArt TZR-01 Adapter and APO Lenses

[Macro_Cosmos]

Thanks! That is helpful. I have never tried and will, although I do a lot of retouching, so have to see how that setting affects retouching.

No problem!
To provide further explanation, ZS usually utilise the very first frame of a stack as a reference, and adjusts the gamma of each subsequent image to match luminance.
The problem with this method is that the first frame for most people is usually devoid of much information. It's usually dominated by out of focus smudge. This confuses the algorithm, causing it to potentially adjust falsely since obviously defocus fields lack contrast, and contrast affects the perception of colour. A work around is using a frame with lots of information as the first image or just uncheck brightness adjustment. I assume you use sunlight, so that option isn't really needed either way. People using flash should adopt the former work around.

It will have a positive affect on retouching since we're denying the software's rights to fondle with stuff we'd rather have unaltered. I have some very dramatic examples if anyone wants to see. Basically having brightness handled results in a completely unusable stacked image.

Wonderful comments. Thanks so much!

That is indeed very helpful info!

Here is a problem.

I just got the Venus Laowa 100mm F/2.8 2X Ultra Macro APO Lens for Sony FE and put the TechArt TZE-01 adapter on it for use on the Nikon Z 7.

The corded remote switch won't trigger the shutter nor will pressing the shutter release on the Z7. I can focus fine (manual) and adjust the shutter speed, etc. But no picture gets recorded. Any ideas?

Got help from another forum. These adapters will work, I am told.

The Pixco is only $13-$15. It is said to work instead of the TechArt.

The F-mount version of the lens has contacts to allow electronic adjustment of aperture, combine it with an electronic adapter for the Z-mount (eh like the one Nikon makes) is the way to go IMO.

Laowa 100mm F/2.8 2X Ultra Macro APO Lens for Sony FE

Trying to get the above lens to work with the TechArt TZE-01 adapter. It won't fire the shutter release.

I wrote to the company and they responded:

"You may need to select in the manual. Toggle on the "Release shutter without lens."

This may be a generic remark, but I don't know where with the Z7 that can be set. Any ideas?

What I need is a dumb adapter.

Tape over the contacts on the adapter...

I finally received the Kipon adapter for adapting Sony E-Mount lenses to the Nikon Z7. This is a DUMB adapter and works perfectly for allowing the Venus 100mm 2x APO macro to function, i.e. let's the shutter release fire. The TechArt TZE-01 would not let the shutter fire.

As for the lens itself, very short focus throw which is terrible for the close focus that 2x requires. I will keep it for use on very close insect shots, but if I stack anything, I will have to put it on a focus rail. Otherwise the Venus/Laowa 100mm F/2.8 2X Ultra Macro APO Lens for Sony FE seems to work OK. Will check it out.

Sample photo with the Laowa 100mm focused on the very tip of the top. Not too bad, eh?

I love it Michael. Just made look it up and there is a f-mount version of the Laowa 100mm APO 2.8 2x coming for around 400 euros?

I like it on the mirrorless Z& with a tiny thin adapter.  I got the Sony E version because it has a 13-blade diaphragm.

[golunvolo]

I see. They are the same price and look like same elements but the nikon version will have a 7-blade diaphragm?

Exactly

Ran some quick tests today with the TechArt adapter on the Z6, everything seem to work fine when adjusting the aperture on the camera but for the Voigtlander lenses the aperture is reported incorrectly, the 125/2.5 EF (with Metabones EF-FE adapter) is now reported as an f/1.8 lens wide open and the 15/4.5 FE as f/4.2.

Can someone comment on exactly how to update the firmware on this adapter?  When I plug in to the USB I don't get the normal alert that a device is attached.  The firmware updater just says it can't connect.  Doesn't seem like it's getting power?  Thanks!
