Thanks for doing such a comprehensive review. I’m your exact test case and have been looking for a review of this adapter. I have a ton of Sony glass but am tired of the lack of updates via firmware. I used to shoot Nikon in the F2, F3 days and so the desire to return is there. I rented the Z8 and tried the Megadap E21 with the latest firmware and had similar results. I think for portraits and even predictable action, it works, and this will allow me to be selective in which Nikon glass to add first. Thanks again for all the work!!
Understand. My case to buy the adapter was some of my wider Sony glass like the 20mm 1.8 G. And I thought, why not test the 200-600 for longer lens shooters and see how the lens does. This adapter will work fine for me for aurora, landscapes, or more environmental wildlife shots with a Sony lens on the Nikon Z
Thanks for making this video. Interesting experiment! I’m impressed with the engineering prowess that allows lenses from different manufacturers to work on the Nikon Z bodies. From your previous videos, the Fringer EF to Z adapter works really well except for not being able to use the optical image stabilization. In this video, it’s clear that the Nikon Z 180-600 works so much better than the adapted Sony lens! The Nikon PF series of lenses are so sharp, fast, lightweight, and more affordable than the traditional 400 mm f/2.8 and 600 mm f/4 lenses. They are quite compelling for wildlife photographers.
Thanks for this video. Nikon shooter here. I really want to keep my nikon up with nikon, and upgrade to mirrorless. I was almost giving up nikon bc sony have many more lens options, specially 3rd part. This is perfect. I can now get a z6ii with is a fantastic camera, and use sigma and tamron lens.
I think I may have found the solution to the AF "pulse" on the Sony. There is an "AF Fine Tune" feature on the Z cameras in the "wrench" menu and many places (including Fringer's manual, but not Megadap) mention that adapted lenses may benefit from a fine tune adjustment. I tried it on my Megadap-ted lenses and the ones needing adjustment do focus faster with less hunting after the AF Fine Tune. Hope this helps.
Thanks for the info. I did try that, but didn't notice it make enough difference to really talk about it. The adapter is still very useful, but you will take a hit with AF in stills and video. Now the fringer with the canon lenses is pretty much dead on adapted.
Ah good to know! I used the Canon 135mm f/2L with the Z8 and Fringer adapter and it was flawless, and faster than many of my native Z lenses. I'll ping the Fringer team to see if they are willing to make an FE->Z adapter since Megadap seems good but not perfect. Congratulations on surpassing 10k subscribers! @@WILDALASKA
Having considered the Z8 or the Z9 and being frustrated with the Z6Ii and not trusting the autofocus system, watching this video really show how much the Z9 improved in that department
I see that pulse behaviour with my Sony A7iv and 200-600...Makes me think its more the lens than the adapted combination..I could be wrong of course....Just about to go Z8 but will be trying this combo before I rush to go to the N.180-600... Cheers for the vid...Very interesting.
I am a long-time Nikon user but I like the mirrorless technology so I bought my Sony a7R3 and 200-600mm before I got my Z7 and Z9. Then, I bought Megadap ETZ21 with the expectation that I can use Sony 200-600mm on my Nikon Z bodies but I was disappointed that with the AF performance. However, Megadap is good for landscape photography or static objects. I believe the problem is the Nikon Z Flange-back distance is 16mm and the Sony E Flange-back distance is 18mm. If the thickness of the Megadap ETZ21 is not 2mm, it could affect the AF speed and performance on the Z bodies. Thank you so much for sharing your thorough test.
It's something in the connection communication. The flange distance is a simple calc for the designers. Example is the Fringer adapter for the Canon EF to Nikon Z works flawlessly.
@@WILDALASKA Yes, definitely. ETZ21 acts like an interpreter but it may not be able to decipher the Sony AF algorithm and the Nikon AF algorithm completely or it takes ETZ21 more instruction cyles (more time) than necessary to complete the communication message (command) per my experience in avionics software. I really like your test methodology. You could be an excellent Test engineer. Thank you.
Thank you for the informative review! I am actually quite happy with performance of the ETZ21 Pro on my Nikon Z fc camera and just enjoy how good Sony 11mm/1.8f is doing in astrophotography 😊. But I am facing a problem, which you did not mention in your review: distortion correction does not work inside the camera. One needs Lightroom to apply correct Lens profile manually, which is strange because all other things are working. Did you experience such a problem? If yes, how did you solve it?
When I do Bird and Wildlife Photography, I am hiking in the Nature and I do want want to carry big and heavy Lenses ! I had the Sony 200-600mm 5.6-6.3 G Lens, but is is big an heavy, not fast to operate and handle, also there are problems with IBIS when using R series Lenses. Now I have the excellent Sigma 500mm 5.6 DG DN OS Sports Lens, which is compact and light weight, easy to handle and operate. If I had Nikon I would get either the Nikon Z 400mm 4.5 or the Z 600mm 6.3, maybe the F 500mm 5.6
Also it seems to me that this adapter is fine for things that don't need fast AF so portraits, landscape and product photography would be fine. Sports, wildlife, wedding and street photography could be frustrating experiences.
I don't know how many stops of IBIS the Z9 has, but the 200-600 stabilization seems really similar to mine on the a7iv, which has 5.5 stops of IBIS. It works better on the a7rV, which is the first body with the new IBIS unit that is rated for 8 stops.
Yes the Sony 200-600 is fantastic. And im testing the 180-600 now and that may be the Sunday video. Both are fantastic . We are spoiled in this day and age for gear 😄
Great video and answered all my questions as I have been thinking of changing from my A9 to a Z8. I wonder if there is much difference between sharpness and contrast between the 2 lenses - perhaps something you could mention in your Sunday video
Just watched your Fringer EF to Z adapter and the autofocus on your EF lenses adapted to Z9 seemed much better, and without the flutter. Would you agree? Maybe the Fringer coders are more skilled?
Had the exact same problem with the ETZ21 original using this combo. It did this weird flutter. The AF performance on native lenses was always just that much better. Can’t beat native. This is one of the reasons I ended up selling all of my Sony gear.
Wild Alaska aka Adapter King. Thanks man this is valuable info. I bought one of the EF-NZ II adapters after we messaged on instagram. It’s been awesome so far.
This comment has been so incredibly helpful! (I'm going to ask the Fringer guys to make a Sony to Nikon z adapter so that we don't need to keep using the Megadap stuff)
I almost think the Megadap is somehow converting the distance slightly incorrectly, and maybe that's why the motors need to do a small adjustment flutter before the focus is spot on.
Good informative video. As I invest in Nikon it is a comfort to know I can use my Sony lenses, until I am ready to purchase Nikon lens. Makes sense to me.
Considering it's putting a Ford engine in a Chevy truck, I'm really impressed with how the Sony adapted to the Nikon Z series. Not perfect and it seemed native was a bit better. Looks like this may be an option for someone who shoots both systems and only wants to invest in one telephoto lens.
Exactly, that was my angle here really. As I have all 3 manufacturers. Some of the wide angle lenses I was hoping the adapter would make it where I could buy 1 lens and use it on both Sony and Nikon Z. Which looks like I can for video and some stills scenarios.
@@WILDALASKA sounds reasonable. I shoot Nikon and Canon. No easy to adapt those systems. This really is cool technology. Thanks again for such a through review and explanation of the pro and cons of this.
I have been looking for a video specifically about this. There isn't enough Z9 adapted lens videos with this amount of information, most just go "its works!" or "it kinda works" and leaves a lot to speculation. Being unable to get my hands on a 180-600 (sold out everywhere) and currently using a 200-500 F mount lens, the 200-600 looks like a viable go between for now (photographing youth sports) and this video addresses a lot of my questions and concerns. Thank you!
Just an update for those who are still waiting for an ETZ from Fringer: Since Fringer is a Chinese company, I am Chinese and have asked Fringer if they will release an ETZ adapter, and the answer is no. They believe that the distance between Sony E-mount and Nikon Z-mount is too short, and if the adapter is made, the strength will not meet their standards. The strength of the direct lens-to-body connection may be a risk (For any ETZ adapter). And they believe that the ETZ adapters on the market are only suitable for entertainment and not for professional use. So they won't launch the ETZ adapter.
There is a few reasons to want to adapt another body's lenses to your current one. It's a lens your system doesn't have any equivalent for. Example if you want to use the Tamron 50-400 lens on a Nikon Z or if you have a nice Sony lens like the Sigma 40mm f/1.4 Art lens or the original Tamron 35-150 2-2.8 and don't want to have to buy it again for your Nikon Z camera (that is my case as I have an A7R4 and a Z8)
it's so cool that with today's adapters, the boundaries between systems are a little blurred. of course, it's better to have a native lens, but... sigma and tamron lenses...
Are there the same problems with the other Sony to Z adapters? I have the Techart and I haven't experienced the same issues. Further, is it possible that different focus settings would benefit the adapted lens vs. the native lens? It would have been interesting to see how the Sony lens performs on a Sony body to see how much better it might be.
I think that these adapters efficacy depends a lot on what you use them for fast action challenging subjects { birds in flight etc } not the best option. Whereas my main use cases are landscape and macro and the typically very good S-AF is plenty for this. Though in saying that ,as a long time Nikon SLR and DSLR user who only went to Sony for mirrorless I did not enjoy the feel ergonomics menus etc of the Sony FE bodies and was happy to "go home" when Nikon joined the fray. I initially used my Sony lenses { 12-24mm F/4. 24-105mm F/4, 24 GM, 35mm,55mm 85mm and 90mm macro } with no problems for my use case. I have since replaced all bar the 24mm GM . The Sony 90mm is very good but the Nikon 105mm is better and more importantly the automated focus bracketing is beyond useful
@@WILDALASKA It is one of the few videos, where I actually profit from. Real life examples, good conclusion... I learn something. I wonder however: how does the megadap with e-mount compare to the fringer-Adapter with ef-glass?
also the same as NEEWER ETZ。 Same circuit board and firmware，The difference from funmount ETZ Pro is that the rubber ring is waterproof and dustproof @@WILDALASKA
My only concern is that you are adding very heavy lenses on the adapters, so you really need to be careful how you hold the camera+lens. Both FTZ and FTZ II for example set the upper limit to 1300gr. Megadap - that I do not own - on the non pro version sets the upper limit to 800gr. The Sony lens is around 2115gr. And the Z9 weights 1340gr. So, you have an adapter that holds 800gr between two expensive items that weighting more.
ANY lens over 3lbs should ALWAYS be carried by the lens and not the body regardless of adapted or not. I covered this in a recent video also. ruclips.net/video/RP8Jq82PKTA/видео.html
I do it ALL the time. The Z9 with the EF 500F4. And the current fringer adapter has no weather sealing. I have on order the newer version that does have weather sealing. You do have some weather sealing on no weather sealed adapters at the body and lens, but it does reduce it.
It's not missing ! It is miss identifying the target, i.e. the eye, this is a problem with settings, not the lens, camera or adaptor. Ooooh! my G, if I put a lens made by another company on to a camera, using a Adaptor from YET another company, it doesn't work as well as it would, if I use a lens made by the same company that made the camera !

It IS missing as the motors are a little slow to acquire and interpret. It's what all adapters do. But how close can it get. Some do some don't. The LENS has no issue. The 200-600 Sony lens is amazing lens on a Sony body. We are looking at adapted and how the adapter works and how close can it get to native performance. No knocks on Sony or Nikon. It's how does this adapter work. That's all. Settle down now 😉 Thanks for the comments

@@WILDALASKA but Z9 is also heavier than the adapter, so you need to hold both.
Why would you ever put an adapter between two expensive units that have no weather sealing ?

You do have some weather sealing on no weather sealed adapters at the body and lens, but it does reduce it.
And cuz a lot of times you don't need weather sealing?
