I'm using Sony Alfas and having bought the Zf and found the Magadap ETZ 21 adapter with my Sony GM and G lenses, it was like using Sony cameras and I got home after my vacation in Tokyo and added a Z9 to my collection. I ordered another Magadap ETZ 21 adapter.

Thanks for the review. I do have a Sony A1 and the 7III and it also has the same focus issue. Sometimes looses focus and I have to turn off and on the camera to get it solved. Been using it for the last 3 weddings and I love it! Now, for the reception I find it not so good, my other Sony, Zeiss and Sigma lenses focus faster than the Tamron when there’s not much light.

Thank you for this review. I am also very interested in this lens for my z7. Is the function button (fn) of the 35-150 operational with the adapter thx ?

Hi, how do you think about this plan if I buy this lens in E-Mount version with Megadap ETZ21Pro to use with Nikon Z8 instead of Z-Mount version, because I want to use this lens in with my Sony camera too. How accurate AF? Is it work fine?

Having come across this adapter I am considering switching from Sony to Z8. Two Z8’s is a ton of £ so being able to use my GM glass to start with will be huge. I love how thin it is. Have you used it with any GM glass? Or the Sigma 84 f1.4 art for Sony FE mount

Hi Shua, This is an interesting lens for sure - I think I would be more interested in a 28-70 f/2 like Canon makes than this as I do not like variable aperture and I feel that f/2 is really the slowest aperture that works well in very low light (IMO) - I like to keep the ISO down. That said, this is a very cool lens and a step in the right direction. I think it would be great if Nikon could make something that was f/2 across the zoom - maybe a 35-85 f/2 - this would be ideal. I am happy to bring along the 70-200 just for the long shots at the ceremony - I find that this is the only time that anything longer than 85mm is really necessary at a wedding. This all said, if it did release as native for the Z mount, I would consider trying it to see how much the 2.8 at the longer end bothered me. Also, I would be curious to know at what point in the focal range that it shuts down to 2.8 - you mentioned at 55mm it was at 2.2 - is it still at 2.5 by 85mm or is it already at 2.8? I'd be interested to know. For anyone that is okay with the 2.8 aperture in the dark, I would say that this lens is awesome, and you definitely got some nice images with it. Good work :) -PD

I almost though myself into NOT buying this lens (too expensive for me at the moment) and your video forces me to rethink everything again 😢 i know i will miss wider than 35mm in tight places like bride/groom houses, but that versatility.... I wish it was something like 28 to 125 :)

The way Nikon and Canon are being so strategic with 3rd party lens makers, I doubt they'll let Tamron release a Z or RF version of this. Similar to the amazing DG DN lenses from Sigma, which is why I'm interested in the Megadap for my Z72. I just tried the Techart in a shop, and it was really flakey - aperture jumped around, shooting mode kept switching on its own. I took it off as fast as I could.... Great vid; thanks.

I have zf + z mount version of the tamron. And only using af-c + burst mode while zooming quickly sometimes the focus get stucked and impossible to refocus, I have to shut down and turn on again. This is not happening on my z6ii body though…

Hi, I am considering the new Tamron 70-180 G2 for use with my Nikon ZF but using the Megadap ETZ21pro since its not available for Nikon (yet?) do you recommend going down this route ? and if it arrives in NikonZ mount later, upgrade it. Did you upgrade your 35-150 to the Nikon Z mount version in the end ?

How did you was able to put the lens on with the megadap. In dpview, the photographer are having problem attaching the lens with the medadap ?

I’m hoping for a Z mount with this lens. Perfect for indoor sports.

I've wanted this lens for my Z7II for some time now. I've used it on a few buddies Sony's that shoot weddings and portraits with just this lens. Your problems may be the adapter, I was going to do this exact setup getting the adapter but I have recently heard horror stories about the Megadap Adapter. From losing connections and bricking after a few uses, issues like you are having or being DOA.

Hi there, Did you buy the Z lens? If so, how it works compared to E with ETZ? Thank you! ☺️

now that the tamron release the z mount 25-150, it is more affordable to use samyang 25-150.

This lens is going to be coming to the Nikon Z Mount

Interesting. Wonder how the Samyang 35-150 version would work? I hear the Samyang is slightly better than the Tamron.

Can you do a review for Samyang 35 150

Don't buy this adapter for this Tamron lense : Due to the rubber ring at the mount, it's impossible to adapt it. I return both adapter and lense :-(

I bought the same adapter for a Nikon ZF, when I got the adapter in the box their was no watchmen to update firmware, any way when I mount a Sony G 24mm f2.8 to the Nikon ZF I can see what I want to photograph but the f stop on my camera screen doesn't register the f stop that the lens is set to and even though the camera was set to auto focus on the screen it shows manual focus, not happy with the setup I bought a Sony A7II open box unit from Adorama camera for 860 dollars, the camera came with a 28-70 kit lens and the price covered tax and shipping, the Sony A7II is a older camera but it is perfect for what I will use it for, it joins my camera collection of Pentax, Panasonic, Olympus, Fujifilm and Nikon cameras.
