One thing that I really like about using a speed booster (focal reducer) is that it protects the sensor from dust when you're changing lenses, etc.

I own a GH5 & GH5s and I have metabones speed booster with the signma 18-35mm lenses, but I have recently got the panasonic leica noticon 42.5mm, which is absolutely beautiful native lens. When using some of my native Panasonic lenses with stablization, I love the dual IS with the lens and the body.

Great conversation. Love the different perspectives . Great stuff.

I really keep coming back to this video, very awesome content, and having your preferred lenses of choice helps so much

This just helped solidify my errors in picking up the speed boosters because I rely on autofocus heavily on my GH5. I was shocked at the constant hunting with the canon and tamron lenses I got to go with the speed boosters. I’m more run and gun and eventually I’ll get the manual focus down but for now I’ll be sticking with the native lenses. Appreciate the info!

This video made me subscribe to your channel. I've been a videographer for 5 years using a LUMIX g7 on a 25mm F1.8 Lens. I shoot mostly music videos and weddings so I've been in the market for a GH5 but I haven't decided on a lens just yet. The video definitely gave me better understanding of what to think about when weighing the pros and cons. Thank you for your content and hopefully we can network soon.

Great conversation here. Most of our lenses come over from the GH2. On the GH2 the 30mm Sigma 1.4 hit the sweet spot for a nice filmic look. It is still the lens we use today for talking head. We weren't big fans of the native glass for GH2, because it looked so sharp. Often used old Canon FD to get a nice softer image. However, with the GH5 we have come to find the native lenses look pretty good. Not Sigma Art lens quality, but good enough for the average KZfaq viewer to not notice. Currently use mostly the Lumix 12-35 2.8 when outdoors. Great small, run and gun little lens. When we first got into filming it was all about depth of field and shooting wide open. Now we find the look of about f4 to be most pleasing for our eyes. This means the 2.8 has plenty of depth for our needs. And all this is why we love the Panasonic GH5. Add a new brand of lens with an adapter and sometimes it feels like you own a whole new camera. Great to have options! Another amazing video by the way Caleb. Also great to meet Bobby and Nate.

Boom! Very interesting stuff here guys! Killing it Caleb!

I love this discussion. You all had great points, Listened three times already.

I really appreciate this video. Watching it for the second time. I just got my GH5 and now I'm getting more comfortable with the manual focus. I initially was all "wait but why stress when you have auto focus?!", but now I appreciate that control so much more. The lenses are definitely another beast that I'm learning about so content like this is golden!

Honestly one of the best videos for GH5 lenses out there. Kudos!

One lens that I love even on mft system the sigma 16mm f1.4. It’ll give you almost a 35mm equivalent. I rented it when I had my gh4 n I loved the image I got with it. Great stuff Caleb I like these style of videos.

Been GH4 and GH5 w/ speed booster and EF lenses since I started. Still curious and wanting to try a native mft lens. Love this video

Your best talking heads video so far. Thank you!

How they all have the perfect light for a Zoom call. 😂 Filmakers go wild!

For Sigma Art shooters, their 14mm/f1.8 on a Metabones XL is worthy of consideration. It pairs well with the GH5 for Ultra Wide, giving you an 18mm FF equivalent if you shoot in challenging light situations and matches the footage shot with other Sigma Art lenses better than the Tokina 11-16mm f2.8 on a x .71 Speed Booster (15.62 FF equivalent @ 11mm). It's made shooting so much quicker when lighting for our go-to 18-35mm, and speeds up editing/CC because it cuts well with our SA 50mm & 85mm. It's super expensive to buy new, but we've found it to be a worthy rental for product shoots.

I chose to mix it up . As an extensive EF glass owner, a metabones speedbooster was a given. As a manual focus video guy and hating fly by wire. Olympus pro lenses are my choice for native lenses. So the manual clutch is a must for me. I chose the Oly 7-14 f:2.8 and 40-150 f;2.8 + 1.4 tele adapter which are superb lenses. To cover the less extreme angles of view and meet my extreme low light needs, this is where the classic combination of speedbooster and Sigma 18-38 and my collection of Canon primes come into play. Many wonder why they should pay more for a metabones than a Viltrox speedbooster, one can debate the optical and build quality of each but my experience is that metabones release more frequent firmware updates to support more lenses and better back engineer their algorithms. Another random thing that is that the GH5 in some cases does not pass on enough power to some older Canon lenses and also Canons cinema lenses but Metabones solves this problem by connecting a tiny power bank with 5volts to the usb contact to drive these lenses. I doubt Viltrox can do that. 🙏🏾

I only use native lenses but I cannot really have an opinion because I have not used my gh5 with any other lenses. I have the speed booster on the wishlist because there is definitely some other glass I would love to check out.

I have owned the 12-35 and 35-100 since 2016 (when I was rocking my GH4) and I call these my ‘Outdoor’ lenses, the 12 -35 is also my choice if I’m travelling (and need to save weight and space in my luggage)! In 2017 I got the 25 f1.4. In 2018 I bought the GH5 and also the 15 f1.7 (so I only need the 12 f1.4 to complete the Pan/Leica trio then!) In 2019 I sold the GH4 and bought the G9 for my photography (and I paid for V-Log so I can use it as the B-Cam to the GH5) and I also got a used Samyang 12 f2.0 for £140 (bargain) and I love that I can set focus to 1metre and stick it on my Gimbal and everything beyond 1m will be in focus oh and I bought the Nocticron 42.5 f1.2 which was a tad more expensive! This year I have only bought 1 lens (so far) and that’s the Laowa 7.5 f2.0 which I haven’t used yet but I plan to use for some upcoming interior stuff. Last month I bought a £15 converter for my two vintage Olympus OM lenses (50 f1.8 and 24 f2.8 which I bought in the 80s) and I was amazed at how good they both look and they are still a 2x crop (I did a side by side comparison with the 35-100 set at 50), I wouldn’t use them for photography but definitely for video. So I resisted/couldn’t justify buying the Sigma 18-35 with speedbooster and likewise the recent 10-25 f1.7 mostly because I love my Pan/Leica primes and I’m not sure about the weight! So I’m still thinking maybe the Pan/Leica 12 f1.4 to complete the trio, accepting I have the Samyang 12 already (but it’s ‘only’ f2.0) although I just noticed the Voigtlander 10.5 f0.95 🤦‍♂️🤦‍♂️

What lenses did you mention for cinema with the GH5?

Anyone else notice that the man for speedboosters is slightly out of focus? Ironically proves the point of using native lenses lol.

Thank you for this new vid! Big Luv

I kinda would like to hear you guys talk about Voightlander MFT F/0.95 versions and see whats your thoughts :)

Excellent content.

Question: I have the sigma 18-35 but Nikon mount using the Viltrox .71x, and I have returned and bought 3 units because I notice there’s like this weird “warp like” look whenever I pan quickly or even have sudden movements. It’s more noticeable when I VFR 60fps. I thought it was the IBIS or stabilization setting but in turning that off,’it still has it. Do you guys ever notice that with your metabones? Is it because it is a cheaper adapter? I would appreciate your thoughts and perhaps even from the other guys. Thanks for this AMAZING discussion and content!

Good discussion.

8:25 Sigma 18-35mm F 1.8

none of you three are using the Laowa 7.5, ultra wide angle, or the Voigtlander for cinematic style ? (but many thanks, very useful video)

I own the mitakon 25mm f0.95 and GODAAMMMNN its amazing!!

Great stuff! Do any of you use the GH5S, as well?

Hey I got an important question, how do you tell if a lens is manual or focus by wire? Like that leica 42.5 lens you used in the g9 video looks like a focus by wire lens but you said you used manual. If a lens has autofocus that means it's focus by wire yea?

Great video like always! Tnks for sharing. I was actually looking for new lens. I been using the 12-35 MM. I saw this one Panasonic Lumix G Lens, 25mm, F1.7 for a great price, and I was wondering if this lent is good for vlogging? What lent would you recommend for shooting in low light for vlogging?

Hey guys, whats your thoughts on the speed boosters available? are the cheaper versions equivalent to the Metabones for technology?

Thinking about pairing a Canon 17 - 55 with a metabones .71 for use with a a Panasonic bgh1 (gh5) for use as basically a glorified webcam for podcast and news channel interviews from home ? Trying to get something good for basically what you guys are doing right now talking to the camera as if it's a webcam but also would like to be able to get some sort of shallow depth of the field and nice blurred out background if need be sometimes when recording from home the house behind you isn't so clean Unless someone has a better recommendation ?

Gh5 alone made 16k subs to my brother

Wait, you three actually expect a CANON-mount SIGMA lens to reliably autofocus through a THIRD-PARTY reverse-engineered speedbooster on a PANASONIC camera? Which of these companies do you expect to take on the responsibility to QA this combo?

I had to wait 15 seconds for a Donald Trump ad before watching this 😭 Hopefully it's worth it! ❤️

Not help at all

I sorry I got nothing out of this.very dissatisfied.
