For the S1H it would be nice to ask if they could add the ability to record open gate 5952x3968 (full sensor area / 3:2 aspect ratio) in Prores Raw up to 24 fps on the Ninja V. The data rate at 24 fps would be less than shooting 5888x3312 30 fps 16:9 Prores Raw on the Ninja V, so it should be feasible? The ability to film with the entire full frame sensor area on this camera is unique and it's my favourite feature - I prefer it to the cropped 16:9 look. It's just a shame that the h.265 codec is awful to edit with (on WIndows at least)
It's actually already possible to record regular Prores HQ with the full 3:2 sensor area on the Ninja V, the resolution is limited to approx 3240x2160 though, which is ok - but Prores Raw at full resolution would be better!
 

I have the Mamiya 645 Kipon focal reducer for the S1H and the 80mm at f1.9 it's a bit soft and the image seems to glow a bit. I think that might possibly be an issue with the speedbooster not being able to handle fast apertures, rather than the lens. I heard someone else who had the same issue with this combination. You can very briefly see this in the video I shot below, at the 1:20 mins mark, when I open up the aperture to max for a second. It's more noticeable in bright conditions than in low light. f2.8 it's fine though - even around f2.4 it's ok. 
  
Can't find the Pentax 67 one, but with the Mamiya and Contax ones, linked below, you can add an additional adapter to mount Pentax 67 lenses (and also have the option to use 645 lenses) so it's probably a more versatile option?

You may get vignetting on some lenses if using this with the GFX due to speedbooster limitations, however I may be wrong. Alternatively Metabones make a speedbooster for the GFX which definitely won't vignette, but it only takes Hasselblad lenses: https://www.metabones.com/products/details/MB_SPHV-FG-BM1

It would be amazing if Metabones did a speedbooster to compete with the Kipon ones, but ideally made it 0.64x or 0.58x to make better use of the 645 imaging circle. The current price of the SL to Mamiya 645 version isn't that bad in Amazon UK, compared to the prices on ebay at least (where you have to order from China). Here it is: https://amzn.to/3dOKTUK
The test I did with the Kipon on the S1H is in the thread below. I mentioned the speedbooster was a bit soft with the Mamiya 80mm wide open at f1.9, but have since discovered that it's actually the lens that is soft, not the speedbooster:

I've got quite a few Metabones products and don't disagree necessarily but its difficult to be definitive in this particular case when they don't make a comparable medium format reducer product for any format.
It would be good if Metabones did provide Baveyes with some competition for these products as the price is pretty steep in Europe at least, though whether this price reflects it being a thus far niche product or Kipon having a monopoly is up for debate.
I've seen quite a few reviews of the Baveyes MF reducers on Sony A series cameras but not on the SL but I think someone on here has done some stuff with one on an S1 or S1H but I can't remember what thread its in.
The one Andrew has is actually mine (long story!) so I'm looking forward to seeing how it fares once this COVID-19 travel situation eases and we can meet up on a bridge somewhere in Berlin and do the hostage exchange for the Contax Zeiss lens of his that I'm holding  
 
 
 
Ah, OK
Apologies.

Pentax 67 adapts to Pentax 645 so you just buy that adapter tube, and stick it on the Kipon speed booster.
So there is the Kipon full frame one for S1 and Nikon Z6... I have the Nikon version from them.
And there is the monstrous GFX speed booster for Pentax medium format lenses too
And that's the one I want next
Kipon doing an amazingly wide range of adapters at the moment.

Matching  different cylinders glass from different anamorphic scope is equivalent of a cylindrical Galilean telescope running backwards, finding a match with different systems that meet the afocal condition. Here are few prototypes  I put together and some sample shots. I hope you like, thanks!

Here's a test I did with the S1H using Mamiya 645 medium format lenses on a Kipon Baveyes 0.7x speedbooster. Shot in 6K H.265 using the whole sensor area which works really nicely with the medium format lenses as it maximises their field of view. The resulting equivalent speedboosted frame size is approximately 51mm x 34mm - slightly larger than what you'd get with 70mm film (definitely taller due to the 3:2 aspect ratio). It's still quite a bit smaller than IMAX though - equivalent to around half the surface area.
I mostly used a Mamiya 645 Sekor C 80mm f1.9 lens and also a 35mm f3.5. I had an SLR Magic variable ND filter on at all times as it was a very sunny day.
This is shot in V-Log and edited in Adobe Premiere which is able to handle the H.265 files pretty well. Would have preferred using Davinci Resolve Studio but it struggles a lot with these files even though I have a fairly good computer (AMD 3950X with an RTX2080 graphics card).
I have updated the camera to firmware version 2.0 and set the noise reduction to -1.
One of the shots was done at 180fps / 1080p.
The IBIS works pretty well, but can get quite jittery - it's difficult to keep the camera stable handheld when pulling focus on the Mamiya lenses as they have quite a long focus throw.
I composed the music using a virtual version of the Mellotron instrument. 
 
 

@Alpicat
Nice, I've wondered about this combination. 
Thanks.

I occasionally watch this channel. His wife often comments on the lack of funds available to afford their own home due to his purchases.

I picked up my S1H from the shop in the UK on Tuesday! I had ordered the S1 originally in late August, but the day after I heard that the S1H would be able to output Prores Raw and I changed the order straight away. I only have a set of Mamiya Sekor C 645 lenses and the Kipon Baveyes L-mount medium format speedbooster at the moment. These work really well with the IBIS, the stabilisation definitely isn't perfect at all but the movement feels fairly natural. 
I decided to shoot an unboxing video, the first time I've tried this! Also shot a little bit of footage but it was already nighttime so couldn't do much (jump to 02:50 for the test footage). That was shot in UHD 10-bit 422 All-I 25 fps, with the Mamiya 80mm f1.9 lens, at ISO 10,000. It's soft at f1.9 but stopping down improves things. Not sure if the speedbooster reduces sharpness too. Not sure I'll have time to shoot more any time soon as this arrived just when I'm very busy, but look forward to shooting more!
It's a heavy camera and does get a bit tiring if you need to hold it a long time, but it's not that bad!

Well here mine ?

Hi, the video is from February 2018 so I used the build that was available at that particular time. The video description mentions that I used 12 bit lossless recording, so it would have been one of the experimental builds from the main website (not from the forum) - this was a few months before Danne started doing the SD overclock hack for this camera. Given that the resolution was 1392x1028 I'm guessing I was using 'movie crop mode' which gives you a full realtime view of what's being shot, the preview is zoomed in 3x in relation to the whole sensor in that particular mode (rather than 5x). 
The Schneider lens was mounted to the camera with a C-mount to EF-M mount adapter.  
That's good to know! I only ever used the 5D mkII without magic lantern (back in 2011) - didn't realise there was less moire and aliasing than when shooting with the regular video mode.

Pretty amazing footage for a camera you can buy for $150.00 Dollars.  Well done.

That could work on my Black magic pocket too, may have to try it once I get a few extra bucks. 

Yes, this is not only a device but a space shuttle... (E : -)

I managed to find one of these filters for a Canon 50D on ebay for cheap (I bought the Mosaic Engineering VAF-50D Optical Anti-Aliasing Filter), and got round to making a video with it yesterday in mv1080p rewire mode (full sensor 3x3 line skipping). It works, doesn't get rid of the aliasing 100%, it's still there in extreme situations, but the reduction is substantial.
I stuck the filter into an EF-M to EF adapter with sellotape, it's impossible to fit it directly in front of the sensor as it's too large - I actually tried to fit it by cutting the filter's frame off, but the glass started cracking straight away so stopped that attempt immediately (you can see a crack in the photo on the top right corner of the fulter, but it doesn't affect the image luckily).

Hi yes I tried it and it works fine. although liveview is a bit crazy with the screen heavily stretched vertically. When corrected in post, the image comes out at an aspect ratio of 4.6:1 which isn't very useable. You can crop the sides off down to 2.35:1 ratio but then you loose quite a bit of resolution. I'll test it further though.
There's someone who stuck an anti-aliasing filter into their EF to EF-M adapter using sellotape, sounds like an interesting solution! I might try that one day!
