Recommend best camera for recording 8mm/Super8mm lenses

[JohnBarlow]

I have looked at the new Pentax Q7 which has 24/25/30  shoot  capability, but the video is crap.

 

Just wondering what forum members would suggest?

[Julian]

Panasonic GH2/GH3/G6 with ETC mode enabled?

[JohnBarlow]

I dont think the panas will work, too big sensor in etc

 

Maybe a EOS M in MLRAW crop?

What Julian mentioned is exactly the GH2, GH3 and/or G6 with crop mode enabled (ETC or EX TELE mode) which allows to use 2/3" lenses, for instance. So it's a viable option.

8mm/Super8mm has image circle of 5-7mm diameter

 

what is image circle in ETC mode ?

Hello, what lenses do you want to use exactly? Since (a) image circle differs between Double-8mm (frame size 4.5*3.3mm) and Super 8 (5.8*4mm), and ( b ) flange distance differs between camera mounts.

 

Most Double-8 cameras have d-mount interchangeable lenses. Their flange distance is so short (12.29 mm) that Pentax Q is currently the only interchangeable camera system to which they can be adapted: http://en.wikipedia.org/wiki/Flange_focal_distance - Nikon 1 already has 17mm, Micro Four Thirds 19.25mm. 

 

For Super 8, very few interchangeable lens cameras existed: Beaulieu used c-mount (but their kit zoom lenses had a different locking mechanism and won't fit regular c-mount adapters), Leitz/Leicina used the Leica M mount (with only two lenses: a Schneider Optivaron 6-66mm/f1.8 zoom and a Schneider 10.5mm/f1.8 prime), Nalcom used a proprietary mount. 

 

I once shot a video on the GH2 with the Leicina/Schneider zoom in ETC mode, and it did vignette. So I'm afraid your only option besides the Pentax Q (shot this video with it, and an adapted f0.95 c-mount lens) might be the Chinese Kineraw S8 camera.

I am looking at lenses from this list

The EOS M interests me due to the custom ML RAW crops, also its throat diameter is big to allow some kind of custom adapter

Note that d-mount lenses will even vignette on the Pentax Q7 whose sensors measures 7.44 x 5.58mm - 2.8 times the surface of the 8mm frame.

 

Here's a comparative test of d-mount lenses:

http://www.filmkorn.org/d-mount-objektive-im-vergleich/

There are big quality differences between them.

 

The EOS M bayonet has a flange distance of 18mm, so a d-mount lens would need to protrude 5.7mm into the camera, perhaps making its focus or aperture ring unavailable in some cases. The EOS M sensor is 22.3 x 14.9 mm; when sampling a video at 1280x544 pixels (AFAIK, the currently possible resolution when shooting raw video with Magic Lantern) in full zoom mode, 24.69% of the horizontal sensor pixels and 15.74% of the vertical sensor pixels get used, which is equivalent to a sensor/frame size of 5.5 x 2.3 mm. That exceeds the horizontal frame size of Double 8, but I guess most d-mount lenses would still cover it...

 

Let me know if you find an adapter solution.

[Nikkor]

50d and 7d with magic lantern in crop mode should give fullhd on a smaller area then 2/3", it's a 4,8 crop factor over 35mm. The only problem is framing, which is a pain in the ass.

If you're feeling adventerous, you could build a custom camera based on a Flea3: http://ww2.ptgrey.com/USB3/Flea3

They come with all kinds of small sensors.

Ha Ha,

Funny you should mention that, I have been toying with the idea of a custom GoPro Hero3 like the VF Novo.which is only rental

The Hero3 teardown is here

It would be easy to machine a new faceplate with C mount or Dmount and remove the lens and mount the sensor further forward. Only issue left would be for some kind Proggy to reengineer the FW to provide exposure lock.

 

At the moment the EOSM looks promising if they can remove the pink focus dots successfully.
