The Digital Bolex uses a Kodak KAI-04050 sensor. The sensor is available in colour and monochrome models. (BTW, the colour ones use a TrueSense filter, not a Bayer filter. ) So presumably there would be better resolution with the monochrome ones than the ones with the TrueSense filter. Here's the spec sheet. https://www.imperx.com/wp-content/uploads/2017/08/KAI-04050-D.pdf I played around with footage from my colour Digital Bolex, using a monochrome plug in that allows you to assign a grey level to any colour tone with a lot of customization. It looked really nice. But probably shooting black and white with a dedicated monochrome camera might be better somehow. There are a few example videos online shot with the monochrome version. The story is that so many people had been requesting custom builds using the monochrome sensor that they decided to just come out with a monochrome model. -

If the monochrome version is also 2K, it'd be a lot closer to a 2.8K bayer pattern camera in actual resolution - better in low light too. That'd be a really fun camera to have. -

Yeah, they're not cheap even though they're only 2K and getting almost 15 years old or older now. The monochrome ones (using the same chip) are much cheaper meaning it could be worth it to roll your own monochrome cinema camera for those times when shooting black and white. -
For anyone looking to do something similar a suitable harvesting product is this Allied Vision industrial camera that uses the same Kodak CCD. They are also long since defunct of course but are available on eBay. https://www.ebay.co.uk/itm/284133056331 I think the price seemingly on the high side is probably reflective of people looking to do a DIY Digital Bolex too but when you consider that a used D16 is not easy to come by and is well north of £5K then for someone determined enough this route is something of a relative bargain. Pi 5 and its eco-system have now matured sufficiently to be able to handle the Allied Vision software in the intervening years so it’s definitely viable as a DIY project. Not trivial of course but viable. -
I am currently taking a good hard look at the V… Not the A7RV that I had, but the more recent V for vanilla, as in none-R, the 33mp one. As a pure stills camera. In a direct comparison between the A7RV I had and the S1Rii that I currently have, bodies only, nothing in it. The Sony has more megapixels which gives more latitude to punch in allowing shorter focal length lenses plus even better (more accurate) AF and is smaller & lighter with battery life and the S1Rii counters with…well with what actually…?? ’Something’ I can’t quite put my finger on… It’s only slightly behind in the above factors and the only thing I can come up with that I prefer over the Sony is, “I prefer using it”. But…and this is the big one and the above confirms it even more, there are quite a few bodies that do what I need them to do, but very few lenses. As things stand, I’m not going to jump immediately, but my primary tool for next year is going to be based on a specific lens, or at least something very much like it and that lens is the Sony 50-150 f2. I can’t quite get past it. It is the perfect outdoor lens for my line of work. Yes I wish it was smaller and lighter but that is it’s only compromise. The cost isn’t because for business use, it’s not that big a deal. But, it’s E Mount only so native on Sony or adapted on Nikon. The more recent A7V beats the A7RV for me as it’s; better in low-light, even faster and more accurate AF and I prefer 33mp when I don’t need to crop so aggressively. There is nothing else from Sony that would work for me as a body. Nikon, I had the ZF and with primes and smaller zooms it’s fine, but with the 50-150 adapted, it would be trash to use, especially as there is no battery grip and I prefer the A7V/S1Rii style fully artic screen. Ditto ZR. And there are reports of banding in certain lighting conditions. If it had a mech shutter and the type of rear LCD I prefer, I’d be all over it. Z8? Could get away with no battery grip and it’s an option… Z9? Prefer it over the Z8 and could be an option… But with both of the latter, there have been reports of this specific lens, the 50-150, not working quite as well as it does natively… And then the final piece of this particular puzzle is the fact that is not a fact but could become a fact, that from within the L Mount alliance, someone pops out a rival lens to the 50-150… No signs but a patent went in a few years ago apparently for a longer focal length to the Sigma 28-45mm f1.8 which was I believe for a 45-90 or very similar. That would do it for me as keep me in the L Mount alliance for all my needs because with the S1Rii I could just about punch in for my needs. So you have 6 months L Mount Alliance to come up with something and it MUST be internal zooming and MUST be f2 or faster and ideally, basically the existing 28-45mm f1.8 in longer focal length such as 45-90 and then we’re good. Because if not, I will almost certainly be chopping in one of my S1Rii’s for either a Sony or a Nikon plus 2 lenses. For video though, all the other (4) bodies and lenses will remain LUMIX/Sigma because as things stand. A. They are unbeatable for my needs. B. The cost to change would be hideous and if that change was sideways at best, what would be the point? The simplest answer to all this is make that fucking lens Sigma. You have 6 months to get it on the market. 7 months at a real push because if there is no sign of it within 4-5 max, I will be jumping ship for all my stills photo needs.
