Andrew, the comments about grading weren’t intended for you specifically. Read the post. I was talking in generalities about recent facebook groups I’d left and a similar entitled tone here. It was not a personal attack but you chose to take it that way. Cmon, I shoot these shots for BMD for exactly this purpose. To be downloaded and graded. If I was truly precious about it I wouldn’t do it again and again would I ? You’re throwing a tantrum, publicly, because you dind’t get an invite to a BMD event that is seems like few even knew about. Somehow you think that’s got something to do with me so you went and wrote a post about me. A really lovely piece too. I’ve said it already a thousand times. I don’t work for them. I don’t have that much to do with them day to day. Last contact I had with anyone at BMD was weeks ago. It’s not my job to make sure YOU get some attention from them. That’s on you to make that case. And by the way, this kind of childish unprofessional behaviour is exactly the kind of reason any company would think twice about working with you. Instead, you launch a highly personal assasination blog post as well as numerous personal attacks because I dared to try and explain that to you in a way that you thought wasn’t deferential enough ? You don’t do this for free. You sell something. I don’t but you actually do. Having traffic come to this site means you have a greater chance of selling something. You sell LUT’s and you sell guides and you use the traffic here to do so. So don’t pretend all this free traffic is somehow a favour to BMD and free publicity. I didn’t even see the post you made about the BMD footage till your personal attack on me, but I noticed when I read your BMD post you’re mixing in a bunch of references to LUT’s you’re trying to flog. How about this... Delete every single post of mine. All the IP that I’ve posted and shared on this forum? All those posts where I’ve shared my knowledge and experience. Go ahead and put your money where your mouth is. JB

I don’t actually work for Blackmagic. It’s not my job to make you happy or smooth anything over when you have an issue with them not inviting you to an event. It’s not my job to pander to anyone. I don’t answer to BMD. Just like you I’m an independent opinion and my opinion doesn’t reflect Blackmagic’s views. I think you’re misunderstand why I’m here. Nice job on the personal attack Andrew. JB

Nope. You all aren't my customers. I don't sell anything. I thought you were professional colleagues. I'm not here to sell cameras. I'm a working cinematographer. I used to enjoy sharing what I knew. I do unpaid consulting work with many manufacturers, including BMD. Feel free to delete every single one of my posts. You don't have to host them. JB

What a shame. Who are these "deep state" BMD insiders that are here pushing an agenda ? Myself and Hook. Who else ? What do you guys think, there's a plot and conspiracy ? You guys don't wat these contributions I guess ? I'm here because I've been a member here for years and I'm on many camera forums and this is just another one I like to read and contribute to where I can. I want to know where all the clowns that were saying on this thread that the world was going to end because BMD didn't have any footage out yet and that definitely meant something was very wrong and the shipping date would be missed. All I've seen so far is that a planned marketing campaign by BMD that has gone off the way they intended. They commissioned some actual filmmakers (not bloggers or camera reviewers) that make certain types of film (natural history, action sports, nature) to make some films and then they released them and the camera originals. Then they gave some cameras, complete with some boxes as if they were new to some secondary users, and whilst having them also under NDA, got them to shoot some test footage and allowed some of them to release that footage. Again. Not reviewers. Not bloggers. About a thousand reviewers and camera jockeys have done a bunch of made up comparisons and VLOGS based on existing footage. (hey I love seeing my footage being butchered by grading nerds) Think about it. No blogger or reviewer ANYWHERE has gotten a functioning camera to shoot with as far as I can tell. Because that's not what BMD want to do with their marketing of this camera. This isjust marketing 101. They need people using the cameras in the many difference specific sectors of the market will use the camera. Camera reviews aren't part of that plan. (though it hasn't stopped people doing it based on existing footage) Until it's shipping, it's their choice to give it to whomever they want. I'm tired of this entitled bullshit. I recently left a few facebook groups I was on for this camera, and I'm doing the same here. Frankly it's juvenile and I don't need the agro I sure hate explaining what should be obvious. There's no slight. BMD have a marketing department and they have a plan and it doesn't involve forums, bloggers or camera reviewers. That's not a snub, that's just them marketing the product in the way that they see fit. JB

It takes a lot of processing power to do what is essentially a detailed and sophisticated real time animation overlay over the live image (or even from the live image) JB

He’s posted a few times on the BMD forum about this issue. Some others have tested his assertions as well. My takeaway is that the edges are “softer” and have more aberrations with fast primes because the design isn’t optimised for the different thickness in cover glass (not made by Sony) https://forum.blackmagicdesign.com/viewtopic.php?f=2&t=71899 and https://forum.blackmagicdesign.com/viewtopic.php?f=2&t=26122 JB EDIT and actually this post and the video below it demonstrates the differences visually. https://forum.blackmagicdesign.com/viewtopic.php?f=2&t=26122#p162887

The sensor maker doesn’t necessarily make the sensor stack. The very fact that the sensor stack thickness is consistent with BMD cameras should tell you this. Wide open lenses with shorter cover glass isn’t the issue. It’s because we’re adding another optical formula in between the rear of the lens and the sensor. The thickness isn’t important to performance either. Obviously or we’d have noticed major problems by now ! It changes the optics performance of what a speed booster is doing though. And THATS the issue. It’s not worse. Or better. It’s just different to other MFT cameras and that means to fully optimise the optics design of the SB you have to change the formula and that makes it less optimal for other MFT cameras. This is about making a correction to get the most from a lens. Many cine lenses that have rear filters for example always have to have a clear filter in because the optical formula is calculated with that exact thickness of refractive index always being there, no matter if it’s clear or ND. This is my “lay” understanding. It gets reported as “non standard” MFT cover glass, but there isn’t an actual standard ! Olympus and Panasonic both use a different thickness, it’s just that they’re close enough together that the same speed booster works fine for both of them. (One is 2.3mm I think and one is 2.5mm) They are also using OLPFs as well as being IR. BMD only have the IR filter, no OLPF. This is about economics. They don’t want to have to make a BMD specific speedbooster, they want the same MFT speedbooster to work on all MFT cameras. JB

It’s not to do with getting focus at infinity at all. its about optimising performance with very fast lenses when shooting wide open. Previously it meant making a specifically optimised BMD SB variant to account for the different IR cover glass thickness. You can still use a regular SB and it will still hit infinity. It’s just less optimised to work with faster than F2 lenses. JB

The Hoya PRO filters are in effect IR cut filters. I’m the same way that Firecrest, Nisi and Lee ND filters aren’t designated IR cut filters but work that way. The sensor is covered by the same low IR cut glass as every other BMD camera is. A regular ND filter will show IR pollution in the right circumstances. JB

I doubt it. Philosophically it's not what BMD do. JB

I think maybe 192 is right because we had some flicker from practicals but I don't think 215 sounds right for day. JB

I had the audio in camera turned off in mine. You don't want to listen to me directing the cast and "handling" the camera. JB

Let's see what you colourists are made of. JB

Leslie. You've admitted you've not watched any footage and have no production experience. You're speaking to an audience here in this thread that has a either a great deal of experience, or lot more experience than you yourself and who have actually bothered to read a little more before posting to an audience of like minded individuals. Consider researching a little more thoroughly at least before throwing some handgrenades of questions like the ones you dropped in your previous post. I don't even know where to begin if I have to explain why it can take much longer to grade a shot than to shoot it. Learning is great, and knowledge can be had here. This is a very helpful community but you have to put in a little effort rather than it being spoon fed to you. JB

It's the same size. Here's some examples of scenarios for me where using a micro that will be replaced by a p4K once I can get one. JB Yes I've been on GEN 4 for a while with the Ursa's and of course the P4K and use them for monitoring. It's VERY hard to go back to using VIDEO. JB
