People say different things for sure so this is my own opinion. But I know two other pros that use the viltrox and they think it's great.

Much appreciated! I've made tons of new videos on the BMPCC4k which might be relevant to you as well

Appreciate it Rodney! Thank you for leaving a comment

Nice!! That's a great selection of lenses. Would love to try the 35mm Anamorphic!

@@JonBear vimeo.com/493118193

Glad I could provide some insight! Keep crushing it!

Thanks a lot Kevin for watching and commenting! Yes this is a very important consideration when choosing between the 4k and 6k variants.

Hope you got it sorted Steven! I almost use this lens exclusively on the pocket 4k. Check out this video to see what my current rig is like kzfaq.info/get/bejne/gLOZnrOk09GlaHU.html

Glad you enjoyed! The BMPCC4k performs great with stabilized lenses. Check my latest video where I filmed a volcano with it using a telephoto lens handheld :D

@@JonBear Maybe I will...😁

Did you get the Metabones specifically designed for Black magic? I imagine it may be worth the price since it compensates for the sensor stack of the blackmagic. When I got my viltrox over a year ago for my GH5, it was after watching a comparison video from Zebra Zone who uses it on blackmagic. He copared the non-blackmagic-metabones to the viltrox was only a hair less sharp. Gerald Undone also has videos on it that solidified my choice. Yes the viltrox needs to be adjusted you're right. I did not mention this in the video but I have mentioned it in previous videos when I talk about it on my GH5.

@@JonBear Yes, I got the Metabones made specifically for the BMPCC 4K. It's also a tighter more solid fit.

@@srandall31 it doesn't show iris control with meta bone's and sigma 18-35mm on the black magic 4k either

@@dylangintherofficial Oh yes it does.

Thank you so much!

Yes but this is not just the speedbooster. The netabones is also soft at 1.2 Most lenses are soft wide open. I never go to below 1.6 myself

Actually, because it’s an APS-C lens the crop factor is reduced to about 1.2x without the speed booster. That’s why you get vignetting at its widest with the speed booster, your crop factor winds up being about .85 with the SB.

That's so cool! I will need to test it! Late reply, appreciate the patience.

@@JonBear I think I was just being dumb when I wrote this. It changes the Apeture, not the focus. Although that is intresting that it can control apeture but not focus

@@WHITEPERSUAS1ON ah yes. I mention this in the video. Being able to control aperture is a must since the lens does not have a manual aperture control. Indeed it is strange that the focus is not working and never has, given that the lens is clearly communicating with the camera. When I use the adapter on my GH5 camera, the focus works btw, so it's a blackmagic specific problem

Yes, i just bought one. You need to update the speedbooster though. It works perfectly

appreciate it! my only substance use is caffeine. Pocket 6k is EF mount native so no speedbooster compatibility - this is why I prefer the 4k

It's a matter of how it round the numbers

Thank you!

Nice one!

Hey bro! Try updating your viltrox or pocket 4k (preferrably both!) Latest update has them both working

Thank you! Nice and short :)

Super appreciate it Josh! On the BMPCC4K you can turn on focus assist, which will highlights red outlines around your in-focus subject. I set this to Medium. So grabbing focus is super fast and easy. Furthermore there is a button on the face of the camera that let's you zoom in on the image. With this you can easily see if it's in focus and it allows fine-tuning. The autofocus on Blackmagic is just tap to focus, so it's never meant to be used while recording. It's a cinema tool, and pros don't really use manual focus. If autofocus is important to you then I'd recommend you look into cameras from Sony or Canon. What type of stuff do you usually film?

Pocket 4k is a M43 camera. So it has a M43 mount. You can get adapters for EF (canon) or Nikon

This happens when the viltrox is out of date. Try updating the firmware on both the viltrox and the blackmagic camera

Yes you can! It has a micro four thirds mount same as the pocket 4k. Although I would check to confirm that the adapter communicates with the camera as effectively as it does with the pocket 4k. Try searching around forums or facebook groups

Try rotating the glass element on the viltrox to adjust. Use trial and error. Gerald undone has a good video for this

For the blackmagic, handheld is a no go. I use tripod. I got my GH5 for handheld :) If stabilization is important, then consider the G9 or GH5. They both match the Pocket 4k very well and use the same lenses

Yes that's exactly it! 18 x 0.71 = 12.78mm 35 x 0.71 = 24.85mm so it's basically 12-25mm once you round the numbers

@@JonBear ah a good guess! thank you for the fast response!

The current one is not that great. I tested many of them and found the best firmware in this video kzfaq.info/get/bejne/la2VfNyDptbbnpc.html - download link to it should be in the comments

@@JonBear awesome

What do you mean by gloom? No focus? At what aperture is this "gloom"? at 1.2? I recommend 1.4 and above

Wow thanks for the hint! Never heard of this speedbooster before 😮 The Sigma 18-35 is one of the most utilized lenses in the indy cinema space, so used ones are similarly priced a new ones. I'd just buy a new one as they've dropped in price considerably since it was released, and you can make sure the retailer sells you one with the newest firmware.

@@nikolaj3988 Dang wonder why they stopped supporting it. Now I want a speedbooster with follow focus

@@JonBear I need clarification here: 1. Lenses have firmware updates? You said the Sigma 18-35mm can be updates 2. And what does it mean "Aputure has a version with follow focus"? Aputure is a company that sells lights. Follow focus is related to maybe the Metabones adapter or the lens itself. Confusing comments... Please explain again? :)

Thank you for the comment! Yes there is for Nikon. However it does not have electronics. So you won't get metadata and you won't be able to control the aperture in camera. Instead it has an aperture control switch on the adapter itself. My friend uses it and it works fine. It's just fully manual and operates like a vintage lens would

@@JonBear Thanks!!!

I can see chromatic aberration on any lens that pushes wide open. I suggest sticking with f1.6 and above

On GH5, it works fine with photos. A bit slow for video. On BMPCC4K, no autofocus.

The nikon version of the speedbooster has no electronics I believe so it won't have any communication with the camera. Instead you adjust aperture on the adapter itself. As for why it is blurred I do not know why. maybe it's at f1.2 and you haven't managed to focus? Good luck!

@@JonBear Thanks for the feedback, so the non-displayed aperture makes sense if it has no electronics. And about the image blurred, I managed to adjust it manually by turning the internal ring and it's ok now :)

Thank you for the comment! I use NPF970 batteries. I have a smallrig plate that outputs 12v from NPF battery. I connect it straight to the blackmagic with a weipu cable. IF you use a dummy battery, make sure to output 7.4v from a dummy plate. Cheers!

@@JonBear I appreciate the response thank you 🙏🏽

Make sure to avoid the Nikon version because the adaptor for Nikon to the pocket4k is not as good as the Adaptor for Canon (EF) to 4k (M43) They are priced differently because the Canon one is for EF - which has much wider compatibility than the Nikon mount

@@JonBear Ah ok, that's what I figured. So, I go for the Canon one? Or the Sigma one?

Awesome! Hope you get good use out of it!

Yes it does not effect your camera settings

Hey Milan! in my previous video I address this question 'why get a 4k over a 6k?' My conclusion is that: 1. Pocket 6k needs to shoot in 6k if I want to film in braw - which means heavier files - and I don't need 6k video. 2. When using a speedbooster, The sigma 18-35 will produce a wider image (almost as if the sensor is larger) on the pocket 4k than on the pocket 6k. It will also speed up the aperture to f1.2 3. I already owned the speedbooster and lenses for M43 sensor cameras so it made a lot more sense to get the pocket 4k for me. In your case, if you don't already use m43 camera, then maybe the pocket 6k makes sense. Especially if you don't mind the massive file sizes from 6k video.

@@JonBear hi thanks for the answer. I dont really know what i am getting into. I own a Sony a6300 right now and have the problem that the 1080p looks disgusting and the 4k has massive rolling shutter. Maybe i could rent the 6K for specific projects? Or is it that complicated to film with that i have to own it in order to "learn" the camera

@@Milan-cf1xe If you have any experience at all, then I am sure you can get up to speed with the camera pretty quickly. It has no "auto" modes, so if you know the basics of iso/aperture/shutterspeed/whitebalance then you can get a handle on it. Other than that, it requires external power and external harddrive solutions in order to record for long sessions. If you decide to buy one, expect to pay at least 1000 euros extra for this stuff. But once you have one, you're working with industry gear. Good if you're selling a video service. If this sounds like too much, then consider upgrading to another Sony APSC camera that uses the same lenses you use now. I know a youtuber named That Icelandic Guy who only makes content about them. Maybe you can get some insight on how to make your a6300 pop Best of luck!

@@JonBear Yes i am now 4 years shooting and focusing only manual so i think i mastered my Sony Camera. Thank you so much for your advice

I never used metabones but with viltrox I made another video where I show what the best firmware is: kzfaq.info/get/bejne/la2VfNyDptbbnpc.html

If you are using the adapter that in the video, then you need to get the CANON version of the lens. As for US and INTERNATIONAL I am guessing it has to do with the markings (ft vs meters)

Happened once to me. Update your camera or viltrox adapter. It should work

or press the release button from the bmpcc4k and twist the adapter back in again while the camera is on.

@@alexvanduong9885 hahaha recently discovered this also

@@alexvanduong9885 thanks! You just saved me a ton of headache. Lol

Correct. You need either a speedbooster or adapter. But good news if you don't want to use a speedbooster, a simple adapter is cheap. You will get a more narrow focal range which a lot of people prefer :)

@@JonBear can you recommend one?

I have the dock and honestly never used it

Thank you for reply sir🙏🤝🥰

No. Only aperture adjustment

Make sure you get EF-M43 viltrox. It should be X0.71

EF !

12-25mm ish yes :)

I thought it being a micro 4/3 camera the focal length would be doubled without the speed booster since it’s a full frame lens so we would Minus from there?I’m actually happy I misunderstood this because I love that focal length you said much more.

@@hamletd3647 The lens is 12-24. Your bmpcc almost doubles it so you're basically getting about 24-48 which is a good range.

You mean the original Blackmagic pocket? It's micro four thirds mount so I assume yes :)

@@JonBear you are correct the OG and thanx also

If you cannot change the aperture then you need to find a firmware on the adapter and camera that communicate together. I made another video to solve this issue kzfaq.info/get/bejne/la2VfNyDptbbnpc.html

I don't know what you mean. Even Viltrox calls it a speed booster on their website. viltroxstore.com/collections/speed-booster

Simple, I didn't calculate with the crop factor. I find it only relevant to add crop factor when comparing different cameras :)

Yeah.. the difference between $150 and $699. I might try some of the DIY hacks to make it fasten more sturdily

Come on, it's in fact BS. This play is almost not noticable, and the lens is perfectly secured.

@@dawidnitecki9143 I agree. But it would be unfair not to mention it in the video :)

Only if you use the lens hood that came with the sigma 18-35

Regular EF :)

Do you have a NIKON sigma or a CANON EF one?

@@JonBear It's a Canon EF but I don't remember you explaining that during the video. Its cool. I figured it out. Its doesn't work for Canon. The EF-M2 should work but not the EF-M2II. I ordered an EOS-M4/3 adapter. That should work. im sending the viltrox back

@@tmdesports3377 That is very strange because I am using the EF-M2II adaptor. It is the one I showcase in the video. If the lens is EF and the adaptor is correct then I don't know what your issue might be. strange.

@@JonBear Your mount on you lens is huge, You Sigma lens small

@@JonBear I make a mistake my Sigma says it a Nikon

I have never heard of this happening with the viltrox however I have had another Micro Four Thirds lens that did not want to fit on the bmpcc4k. Maybe try asking in the bmpcc4k forums on facebook groups, or reddit

@@JonBear it’s okay, I managed to fix it. Nothing was wrong, I was just being to careful and not turning it properly haha 😅

@@martianmilktvofficial I'm glad you got it sorted! I have been using the viltrox adapter almost daily for over 2 years now and it still holds up well. Best of luck filming with it!!

@@JonBear thank you very much!

Another great lens is 17-50mm f2.8 from Sigma! usually you can find it even cheaper

@@JonBear Thank`s.

For which type of sensor size is the SIgma 18-35mm?

Are you using a lens hood? The Sigma 18-35 is also an EF lens. I got vignetting when using the lens hood. The reason is because the viltrox will give your lens a wider image than on a apsc sensor that the lens was designed for. Hope it helps!

@@JonBear Thanks for the quick answer! No I didnt use one when I recognized the vignetting. When I use a lens hood the black edges are even bigger. When I'm for example at 50mm and at infinity focus no vignetting, but on 50mm with very near focal range very big Vignetting as long as I'm using full sensor size. It's not a total disaster because most Projects I shoot are full HD and 16:9. Which means I can Crop in when the vignetting occurs. But I feel a bit limited with this great camera, that I just bought 2weeks ago. :/ I'll keep you updated if I find a solution. Great work btw really liked your video. Looking forward for more

@@Creator-it7bh Hmm then perhaps the lens is just too wide at 17mm. It's just the quirk of working with lens adapters, every lens will be different. Interesting that how different the 50mm is at near focus. If you need a wide lens, most people use the viltrox with the tokine 11-16 Thanks for the comment!

I own a 4K bmpcc and a few days ago I also bought a sigma 17 50. Unfortunately I realized a big vignetting problem with this lens up to 28 / 30mm shooting in C4k. On the other hand, in UHD the problem is not there. Although there are ways around the problem, this thing bothers me a lot and I think that sooner or later I will switch to lumix 12 35. From some videos I have seen on the net it seems that the sigma 18 35 also suffers from vignetting and in any case it does not I take it into consideration because it is a very heavy boulder!

Thanks a ton! Love how it turned out

This sounds like a connection or firmware issue. For the pocket 4k I discuss the best firmware in this video after lots of testing kzfaq.info/get/bejne/la2VfNyDptbbnpc.html
