L mount Pyxsis

Hi, I’m in the process of buying an L mount BM Pyxsis. Initially I want to use my Sirui Nightwalker lenses until I decide on some FF glass . They’re APSC lenses but the Pyxsis sensor which is 6K open gate 3x2 will allow a crop to APSC. My Sirui set are F mount . Does anyone know of a suitable adaptor that will work . Thank you in anticipation.

Thank you , the more I learn about it, the more it makes sense for my use case. I Love the XH2 S but rigging it out for Video is complicated and very time consuming, and although the need to rig out the Pyxsis still applies, it also provides for a much more stable and versatile platform. The interface is far more intuitive too.

Blackmagic really does a good job anymore. I stick with mirrorless for video these days, with the good stabilization and autofocus for hand held. I'm using the S5IIx, and have started to look at adding a GH7. As you suggest, sometimes rigging with a cage can suck; I'm just starting to think that through for a GH7.

There are devices called Cinebacks which would attach to your existing cage for a mirrorless camera, while not relying on the cage for rigidity as such, as the cineback itself forms a rigid shell and transform your camera's shape into a rectangular cuboid. It appears to overcome the tendency for a cage to flex or loosen from the retaining points, which of course are minimal in number and are a major issue. The Cinebacks give a lot of options for rigging, as the plates forming the cuboid are essentially Cheese plates. They often incorporate D tap power outlets as part of the shell's design. This is a link to an explanatory video; there are a number of manufacturers, but this video talks about the Camera Foundry brand which I understand is one of the better manufacturers of Cinebacks.

The only Cineback I found for the GH7 is from Rigid Pro, an Australian company. I like the concept, especially for the D-tap battery mount and power distribution. This seems much better than using rods. But the hot shoe is blocked, which rules out the 32 bit floating microphone adapter, which is one of the reasons to get a GH7.

Rigid Pro also has a version of the S5IIx. This is a YouTube about rigging the S5IIx ....

 
Yes it’s a minefield, but may I suggest maybe having a look at XCLS, a company that just appeared on my YouTube notifications who I know make a Full Metal Jacket, - a full enclosure aluminium alloy, rigid cage for the PYXSIS. It has all the mounting points of the PYXSIS body, plus literally dozens more. It’s a very well thought out design and the attention to detail is impressive. It has an optional rear plate that utilises the rear face if you’re not using BMP batteries. I’ve seen the Rigid pro for the S5II . If XCLS don’t make one for the GH7 they may be worth keeping an eye on for future releases. .

Video ignoramus question - why would anyone want a full metal jacket cage like this?
 
Good question. It firstly provides a lot of protection to the camera body, especially given the potential use on commercial projects. Secondly it provides for maximum flexibility for rigging purposes . If you buy different rigging components from a number of manufacturers you inevitably find that not everything is a perfect match when it comes to compatibility. Why not buy everything from one manufacturer? They may not produce everything you need or want and you may have a favourite handle for example you want to use on a new rig . The more options you have for mounting equipment the better an ergonomic and practical solution will be the result . The cages for Mirrorless cameras are not ideal, having only two to three mounting points maximum - when attaching the cage to the camera that is. That puts a lot of stress on those few points of contact when you begin adding other rigging components to the cage, some of which are known to flex. You are trusting your camera to a couple of M3 screws in some instances . That is one of the real disadvantages of mirrorless cages . A box cinema camera provides for much better potential solutions. A full cage for the camera like the XCLS provides both the ultimate protection and the optimal options in terms of mounting components. .

Thank you. Maybe one day I'll move that dial on my camera to "video" and see what happens!

Indeed, why not ? It’s a very different game as you may well appreciate . There’s a whole new technological language to get to grips with, but for many videographers/ cinematographers it’s the process that grabs them. I do still photography but I really lose myself when shooting video and cinema style footage.

There are plenty of F-mount to L-mount adapters. The inexpensive K&F work for me. Though I don't have F-mount but instead K, M42, OM, C/Y...

If you want to preserve auto-focus, that's a different matter.

Sorry , I misled you . I meant X mount not F . I was thinking F was Fuji for some reason!

You can only mount a lens designed for a larger flange distance on a camera with a smaller flange distance. That's just physical reality, since you can add a tube to make up a distance that's lacking, but you can't hack off part of the existing lens to make it smaller! (Well, in some cases you actually can, but that's a different topic.)

Typically, we mount lenses designed for SLR cameras on a mirrorless camera.

Brian Smith has compiled the flange distances for all existing manufacturers. Fujifilm X-mount is 17.7 mm while Leica L-mount is 20.0 mm. So, no, this is impossible.

The good news is that the native L-mount lenses from Panasonic are uniformly excellent. So if you sell out of your existing system you can buy back the focal lengths you need.

Thanks for that explanation and the link. Yes, I bought some APSC Siriu Night Walkers for the XH2S . They are nice lenses and ‘theoretically’ could be used on the Pyxis , but having bought a full frame camera with 6K open gate I want to take advantage of the 3:2 sensor. The Sirui are a set of three 24mm, 35mm and 55mm and although I like the XH2S image I find rigging it out is a pain and the ergonomics are not good because of course it’s primarily a mirrorless stills camera. The menu system is so frustrating, the hoops you have to jump through to just NOT get the viewfinder data baked into the footage is crazy. could’ve been so much better. It’s to be hoped the Eterna menu system is more practical and user friendly, it should be it’s got one job to do!. So decisions are to be made.
