When adapting older lenses (like non-micro 4/3 lenses) or lenses from other systems, a camera body with phase detection autofocus will give you much better results than one with just contrast autofocus. With phase detection, the camera can do some magic math to calculate almost exactly where the focus point should be without needing to move the optics back and forth. It can then tell the lens electronics exactly where it should position the optics to get there, which need to be moved only once. With contrast detection instead, the camera has to guess where the focus should be, move the optics to that position, check the contrast, move the optics again, check the contrast once more, and repeat this process multiple times until it finds the point of highest contrast (which is assumed to be the sharpest focus). This is fine if the lens' optics can move quickly, but if you are using large, clunky telephoto lenses, older lenses with slower electronics, and/or lenses from other systems via an adapter (which inevitably introduces latency and delays), the focusing process can become so slow that the camera struggles to keep up with moving subjects and changing light conditions.

Two different price points

I just purchased a stigma 50mm 1.4f for my GH5 with either of these adapters work for it? And which is the best for it

With the face detection, did you turn the tracking on? No, well there you go it's not going to track then is it. You're using a Canon lens with slow focus motors and expecting it to AF quickly without DFD? What did you expect? Did you select the appropriate AFC/AFF custom Set? Like duh, learn to use the camera.

Do you have the website link to the foam?

Keep in when filming, tend not get to sharp I like some soft focus effect. To me it’s no a big deal to a sharper adapter.

Hello, i hope you still doing great this year. I have question. Lens: Canon EF 17-40 F4 L Camera: Canon 5D mk ii & Sony A7ii Adpater: Viltrox EF Nex IV If i use canon FF sensor lens on canon FF camera and i shot on 17mm fl, the image output will be exactly 17mm wide. When i use canon ff lens on sony ff camera body with the adapter & i do the same shooting on 17mm, would i get same result? I mean i get exactly 17mm wide image, or it will be different like wider or narrower image because there's something called mount conversion factor? I ask this because im new to this adapter, and i want my canon lens work exactly like on my canon ff body.

You'll find all the inspiration you need on woodglut instructions.

A friend of mine just gifted me with a canon 70-200 and I only have a GH5 body. This video saved me, by a lot! Much mahalo🤙🏾

Im getting "lens attachment fail" while using viltrox on my gh5 18-35 sigma

Test again with Firmware 2.6...

You say they performed virtually the same but that magenta shift on the Viltrox doesn't look too nice on the face. Are you the Driftwood guy who's hack I still use on my GH2's?

really good video - you have a natural presentation ability

Exactly the info I needed thank you!!!

this was so satisfying to watch

What was the foam called? Kaisen?

Why the annoying and overpowering background music? Why? It ruins what might have been a decent video.

Great video this was a lot of help. I’d assume the Nikon mount to MFT would be similar. I freaked out when I saw Jesse driftwood in the shot. I’m assuming you guys are bros?

Thanks Zack

Well done! So much useful info in a small amount of time. Ty for sharing!

a bit too technical for my understanding, but I still found the comparison useful

So many thanks! My mom said she could spend 200 on lens adapter and I was surprised when I saw the Metabones was 700. But luckily, its not as big a shift as I feared. Viltrox is fine.

Helpful and straightforward, thank you!

Top-quality Video! Good Job

Are you or anyone else having problems with the Viltrox speedbooster or adapter with the GH5? I have the GH5s and the Viltrox EF-M2 and I can't turn on IBIS. It's greyed out and won't let me alter it. I've tried the newest firmware upgrade for Viltrox (3.5) and also downgrading it to 2.3. It was 3.2 when I first got it. Frustrating as hell. Doesn't matter if I'm using the Sigma 18-35 or my canon 50mm lens.

Been the person that make this awesome guy get to 1k subscribers makes me super pumped

Hey, great video. I have one question, can it be used without the auto-focus on a GH5? Ty

this info was exactly what I was looking for. Great intro as well

just bought the Viltrox adapter NF-M43X. Indeed it takes nice pictures with nice bokeh (I tried with the Nikon 1.8/85 mm and the Nikon 2/35 mm) on my Lumix GX85. But at infinity the lens cannot focus. Has anybody a tip to use these lenses at infinity?

I think this is a really significant test of image quality. I have a two Zhongyis and a Viltrox and they all seem to give acceptable image quality including sharpness on APS-C bodies. If budget's a consideration then it's a no-brainer. But with some full-frame lenses you can get what to me is a noticeable loss of sharpness on a M43 body. If you want to use those lenses professionally that way it would be interesting to compare the .64 to the .71 and see how much of that sharpness you can recover. I'd rather use my good full-frames on all the formats I own and not have to buy high-end native glass for each. That's likely to cost a lot more than the Metabones. Just my $.02.

do you still gain a stop with the Viltrox?

What's the bg music you use? Thanks

Thanks Man💯

Very useful. I just bought the Viltrox and I'm waiting for it to arrive for use with my Canon 70-200 F4L on an Olympus OMD EM10ii. Thanks again!

Well done with the review 👌🏾 detailed but clean and to the point

TY

I've been using the Nikon version of the Viltrox for a few years and love it, but I thought I'd look into getting the Canon version to for the AF capabilities...but with this performance, do you think using the touchscreen to help it out would work?

the coffe makin has some major mckinnon vibes

Do you reckon the face detection has improved with the v2.6 firmware? I've not used it much in the past

How is the autofocus now after 2 years of updates of both camera and adapter(s)??

Very nice! Thank you. Just missed a low light performance test.

great video, gesh Know im kicking myself, I used the gopro mostly on my kauai trip, and did some photos with fuji x-t2, can you tell me your video settings in camera ? I know you mentioned astia would you town down highlights and shadows to minus 1 for a place like kauai for pictures and video?movie auto focus did you use multi or area?im a fan of a astia but usually i bump it up shadows and highlights to plus 1. any tips welcomed.we hope to make it back to kauai in time,did you find the fuji x-t2 big for vacation use? great work keep it up.im amazed at the footage you got, especially with no real colour correcting.i myself shoot jpeg, im very happy with fuji colours. here is our family trip,vimeo.com/301388298. hope to hear back, cheers Adam

can you attached a leica 12-60mm made for lumix onto the viltrox ef-m2 ? or only canon lenses?

so that canon 24mm is actually a 48 mm on a MFT due to the x2 crop factor but if attached to the MB XL it would be 30mm focal length? Noob question but whats the point of different focal lengths? like whats the best sweet spot lenses for a gh5 since it has a x2 crop factor and .64x? Also what about lenses that are variable such aat 18-35, how would a XL speedboost affect those? thanks and great vid

dude. subscribed. you should make more videos. Great and concise!

badass review

That 2.6 firmware update tho 🙏

Run for Prez, dude. Straightforward, intelligent, well spoken. I appreciate the knowledge 🙏#followthisman
