Thats what I said. In 1981.

Yes. The Lens Regain does smart things but remains a dumb adapter at the camera end as all of its electronics are external. If you look at the rear of it, you will see a void where the lens contacts wold be on an MFT lens so there is no connection at all with the camera electronics.

I'd be inclined to splash out the extra few quid and get this type of one which also has an aperture control lever so you can use it with G type lenses as well. https://www.amazon.co.uk/Gobe-Lens-Adapter-Compatible-F-mount/dp/B07587RDCP

They refer to it on the spec sheet as "approx. 1.5 times". It caused enough confusion at the announcement that I would have thought they'd have clarified it in a new sheet but they've even left the "clop" part of it on so I guess not!

I can't speak for anybody else but I'm certainly not saying that. The "Crop" reference is in the stills section, not the Movie Recording section. The figures in brackets after each primary resolution such as this : Are indicating what the resolution will be in crop mode if use an APS-C lens (which Sigma refer to as DC lenses for their own brand) hence this indicator at the top of the listings. An unfortunate translation with "DC Clop Mode" as it should of course read "DC Crop Mode". If you look at the spec for their SD Quattro H, they illustrate this a bit more clearly as its on a separate tab but if you open both you will see the same process, albeit with a smaller reduction as it is not being based on a FF sensor as the SD Quattro H is an APS-H.

It has a crop feature that is clumsily positioned in their spec sheet above the video specs to give that impression but it actually refers to it auto-detecting APS-C L mount lenses from Leica and Sigma's own upcoming ones.

Yep, because you wouldn't want to risk any of it being out of focus.

It very much depends on what you're developing it on but I'm guessing in the context of what this will be used for that some artefacts would be acceptable to achieve the real time aspect of it?

Fuji XH-1 as well.

Its doable with something custom written. You record the incoming audio to files in increasing time chunks depending on the slow down percentage that you want, to take into account the time it will take to play them back. So for example, lets take a half speed playback scenario. The incoming audio (FILE 1) would be written to a file after the first 0.5 seconds and the playback of that file would begin immediately when its finished writing but at half speed. Simultaneously, the still incoming audio would immediately start writing to a new file (FILE 2) which would need to be of sufficient length to cover the length of time the playback will take to complete the first file before it is ready to play this new file. As our first file is 0.5 seconds, it will take 1 second to playback at half speed so our new file (FILE 2) will need to be 1 second long and this will immediately begin playing upon completion whereupon we begin recording another new file. This file (FILE 2) will take 2 seconds to play back at half speed so our next file (FILE 3) will need to be 2 seconds long. As this will take 4 seconds to complete playback at half speed our next file (FILE 4) will need to be 8 seconds long. And so on and so on. I've done you a spreadsheet illustration Depending on what you are going to run it on and how long the piece is you could do this in memory of course with buffers instead of writing to files. The audio of course will be playing back at half pitch as well as half speed but there are enough affordable hardware solutions out there nowadays to take care of that.

I don't want to put his name in case people googling him end up here ! If you put "Nikon 50mm 1.4 K Non-Ai to Ai Conversion" in YouTube you'll find him. Tune in next week for "3D pop from Zeiss lenses - is it a myth?" with your host Ted Bundy.

Yeah, so this is weird. I was going to say that I'm pretty sure people have modded them to be ai and that would one way forward and that I'd found you a tutorial video on YouTube of a guy doing it. So, I was idly reading the comments, as you do, and lots of people were commenting about him being a murderer and I was thinking "well its an old lens and I can see why people might think its heresy to be messing with it but calling him a murderer is a bit over the top but hey this is YouTube so...". Anyway, curiosity got the better of me and I googled his name and it turns out he's an actual serial killer.

I don't mind them either and I think if you're going for a set then it makes a lot of sense, particularly as if you do end up using a follow focus system then it is far easier with having them all aligned. Yeah, if you don't want to speedboost them (and they are arguably fast enough and have decent enough wide options to not especially need to) then you can use the lens throttle and again, if you go for F mount stills versions, then you can use a very thin F to EF adapter on to it to get click less aperture control of the lens and variable ND behind it. The only downside to the lens throttles is that there is no fully clear setting so you'll always have some ND in play which may be an issue in very low light but, again, these lenses are fast enough to mitigate it somewhat. Yes, Auto SS and Auto ISO would still work.

Haha...yes, ignore all that bollocks that I wrote in my last post @kye and buy F mount stills versions as this option is indeed the best way to have your cake and eat it regarding the smooth aperture and retaining the focus grip if you are going to be using them on a non Nikon body. Just set the aperture to minimum and you will then have a de-clicked smooth aperture control. The only caveat is that most of them don't have a scale so it'll be purely manual by eye on the camera exposure meter regarding exposure.

Which the path of least resistance to achieve (if you don't want to open the lens up) is through getting the Cine DS version and adding something on to the teeth to make it easier to hand focus. The grips I linked to can have the gear belt reversed like I've done here to my 14mm to illustrate for you (though obviously trim the end unlike I've done here). If you don't want to use the lever (although it is actually operationally not horrendous to be fair) then you can just use a regular gear belt reversed to give you a grip. To be honest, the gear teeth themselves are not really that bad and there is enough space between the focus ring one at least to fashion a grip with some rubber grip tape. But yeah, if you don't mind opening the lens up (and listening to Guns&Roses while doing it if that video is anything to go by), then de-clicking a stills one might be the way to go and you can certainly save a few quid going that route too.

Nope. Once the app is in the Play Store, all of that stuff is taken care of by your phone's OS so its possible your phone had an update that maybe didn't sync all the apps? Google made some changes to the icon specs recently which may also have caused it but I haven't heard any other reports.

The Cine DS line are de-clicked. If you don't want to use a follow focus system then these are a cheap low tech option. They are under £10 for a pair https://www.amazon.co.uk/Adjustable-Follow-Focus-Notched-Rubber/dp/B07CVBNTHG I'd get EF as you can then have the option of using it on a Speedbooster on your GH5.

Pretty much your first sentence plus a PL mount option. This is a brief history of time for the Samyang/Rokinon range. https://www.google.com/amp/s/thecinelens.com/2016/01/13/rokinon-cine-cine-ds-and-xeen-whats-the-difference/amp/ There are a few tests on YouTube that support the same conclusion. The Cine DS ones are the sweetspot but you need to be a bit more creative ND wise for the ultra wides as they have fixed hoods on them.

The advantage of modern fridges for run and gun film making are that many of them do actually have e-ND built in to them.

Its just the regular MC-21 that has already been released so around $250 for EF version and around $125 for the SA version. The MC-31 is stil TBA but I'd guess it will be closer in price to the Wooden Camera PL to L mount at $499 than it will to the Leica one at $1399. For a budget option, Fotodiox now do one for around $150. For a really budget option, you can download the 3D files off Sigma and print one yourself !

Their consumption tax went up to 10% at the start of the month, so that is 200,000 net which does equate to the $1899 then. In the UK that means it should be roughly the same price in pounds of £1899 when you add the VAT and puts it into the same range as the Z6 and A7iii. I think both of those cameras certainly have quite a big edge currently regarding native lenses, AF and EVF amongst a host of other things but RAW to SSD and tiny form factor for modularity are very big and likely decisive factors for a lot of people here? The equivalent of a 4K Full Frame OG BMPCC for £1899 versus the 6K Super35 new generation BMPCC for £2200 is an interesting dilemma !

Well the UK government banning freedom of movement next month will take care of that though, to be fair, if you've ever seen the elderly nude Brits playing beach volleyball there then some of their body parts are enjoying waaaay too much freedom of movement anyway

I think they can be used in the scenarios they are showing, but only with the supporting gear they list rather than in the way they actually illustrate the operators doing it Whilst the AF solution is quite a few months away, my small hardware interface to use the Tilta Nucleus Nano focus controller with the electronic lenses (as well as the software route via our app) isn't. Without blowing my own trumpet unduly, it makes a pretty significant difference to manual focusing control with native lenses and can offer some mitigation operationally for not having an AF system worth the name. No wires, no motors and no additional powering also makes it a lot more friendly for smaller configurations.

Whilst I don't disagree at all with the overall point you're making, I think it is fair to point out that Blackmagic do actually show it in a numerous scenarios in their marketing that would fit into that sort of use, at least in the way they are representing the cameras being used by the operators. Although the detail in the equipment used section for each scenarios belies those illustrations, which is a bit misleading as well. https://www.blackmagicdesign.com/products/blackmagicpocketcinemacamera/workflow
