Adapter thread. The new Lords of the Rings.

Suspect that the 80-200/2.8 is too heavy for the tiny focus motor in the adapter which are probably optimized for short primes around half a kilo max.

Absolutely so. Even if it worked, I wouldn't use it, to avoid strain on the helicoid of the adapter. And that is why I will soon buy the 100-400 to have a native Z tele zoom.

But the slowness is not only a matter of weight: the 105 is not that heavy, but still struggles due to the heavy aspherical aberration of that lens and of its focal length. Some manual prefocusing is absolutely required.

Here’s a review from Photographylife of the Megadap MTZ11 adapter:

I just acquired an Asahi Pentax with the 58mm f1.8 in a M42 mount.
I also got 2 Soligor lenses with T2 Mount, they where used an an Exacta camera, I concluded it from the 2 spare T2 mounts
What I want to do is to use at least the Takumar on my Z6, but I don't have the adapter, and the I found used online, is currently packed away
I would like to test before being some other adapter, so if someone I the Copenhagen area would lend my one for a couple of hours I would be very happy.

The f/1.8 version of the 58mm Pentax lens is quite hard to find.  Usually the 58mm lenses had f/2.0 or f/2.4 apertures.  The 55mm and 50mm lenses came much later.

I will be interested to hear how your 58mm f/1.8 performs.  They supposedly had beautiful bokeh.

I got it with the original sun shade
I was not aware that it was something special.
I just ordered a K&F adapter, will post my findings in the lens section when I have had the opportunity to get some pictures.

Although this thread is a little moribund I thought it might be a suitable place to ask if anyone else has tried / is using the MTZ11.

I just picked one up second-hand, and have played with it for a couple of days. My verdict is that it kind of works, but is slow. Many of my old Nikkor lenses have a longer focus throw than it can cope with when the lens is set at infinity - so I need to pre-focus a bit.

It works, but I feel the need to pixel peep and check each time to confirm. It takes longer than just manually focussing the lens!

I am in Japan, and had no trouble finding a huge number of used ones for sale - which makes me wonder if it’s the same everywhere. I can see the ‘need’ for the Sony > Nikon Z adapter, but I am now dubious about the efficacy and need for a Nikon F > Z auto focus adapter.

I had almost forgot I have a MTZ11.
When I got it I used it with a 50/2 Summicron. It worked quite well.

I always forgot which aperture during the initialization of a new lens the camera should be set to so it is stored in the EXIF data.
Often I just used it without the correct setting. The adapter works fine without. I normally store images on the PC with a folder name telling which lens was used.

Maybe I should check for new firmware update now I have the adapter in my mind.

When adapter was released there were a couple of updates which "fine tuned" the AF-performance.

[MEPER]

There is a quite recent v.3.0 of the firmware for MTZ11.

[MEPER]

MTZ11 firmware was not that recent. V.3.0 is from oct. 2021 and I already had it installed.

[Snoogly]

It seems to do very good job with the 20mm 3.5 ais, but with such a short focus throw it is to be expected - and arguably it is not even needed with a wide angle lens.

I will continue to experiment until I find the optimal lens to become a permanent AF lens.

This new Leica-M to Nikon-Z AF-adapter looks very compact:

[Snoogly]

I have just sold the used MTZ11 I recently bought. With all the faffing around, I just couldn’t justify its use vs manual focus. However, this is just me. I think for certain people, for certain lenses, for certain uses it could be a useful tool.

[Hugh_3170]

No mention of the Z5 - is the Z5 an exception that it does not support or is it just an oversight in not mentioning it?

I am quite sure they just forgot to mention the Z5:

"Compatible with all the latest Nikon Full Frame & APS-C camera models (Z9, Z7II, Z7, Z6II, Z6, Z50, Zfc, Z30, etc)"

"etc" = Z5 ? :-)
