  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Spike Black... First Prototype photos.

Can your mount use EF-S lenses i.e. 10-22

Erik:

Can your mount use EF-S lenses i.e. 10-22. It seems to me a mount could be made to use either - that is if the mount is the same as on the EF-S (digital rebel, d20 d30 etc.) it could use either since supposedly the compatibility issue is that the ef-s lenses stick out too far and would hit the mirror on the full frame cameras - not an issue on the RED. We will be making underwater housings for the RED and the ability to use this lens would be great and we have a LANC control board that could probably be easily reprogrammed to work your mount for focus, iris, etc.

P.S. The chip size of the EF-S type camera is almost identical to the RED Mysterium sensor, so coverage shouldn't be a problem.

Today we got our Canon EF mount working with a follow focus control that is being developed by a video oriented rental house. The development of a servo focusing mode for our mount is not yet complete, but todays efforts demonstrated that it is possible and produces a very pleasing result. I will post some more involved test information tomorrow. Today's testing included the 85mm f/1.2 II, the 100mm f/2, and the 200mm f/1.8.

My rental house colleague has brought about twenty lenses that we will be testing tomorrow. I will have a new update. Important thing is, this is no longer a speculative project. The box with the knob on it is the easy part. We have finished the ard part.

I thank everyoe for the constructive suggestions; the emails and the phone calls suggesting features and dos and don'ts. Please keep the information flowing in my direction.

We will start the development of the "box with a knob" shortly. So if you want to provide input please do so soon.

We do support EF-S lenses. When the first came out a few years ago there were some mechanical issues. Fortunately it was early in the product lifecycle before we had paid for an injection mold for one of the parts.

You raise an interesting point, the coverage of many of these "digital" lenses is quite good for the size of the Mysterium sensor. This is true for the Canon and Nikon lenses, but not so much for the FourThirds. I am quite impressed with the construction of some of the Nikon AF-S DX lenses that we have been playing with the last few weeks. Seems Nikon was forced to compensate for all of the backlash in their mechanical focusing system in the pre-AF-S days, and carried over some of this learning to the newest lenses. The Nikon still will have a mechanical linkage for the iris - a limitation. But I suspect our servo focus mode (for use with an electronic follow focus controller) may work much better on the cheap Nikon lenses that it will on the cheap Canon lenses. It is too early to say this definitively, but I can safely say that I think the Nikon platform is going to offer some interesting benefits we hadn't initially expected.
 
Erik, can you make a small box with two knobs on it for adjusting exposure and focus, so we don’t have to connect laptop to your adapter?
I am afraid that RED will be busy for some time and Canon EF mount is not on the top of the list.

Do you mean something like this? (see attached picture)

This is the prototype control unit from MTL Video that should be out by NAB. Theirs will be built like a tank. Ours will be much less expensive - made from injection molded plastic rather than NC machined aluminum. We will have more details soon.

Before anybody complains about any ergonomic details, please let me stress that this is a PROTOTYPE! And, there is an iris know that you can't see in the picture.

It works really well with a bunch of lenses. We still have some work to do. We have been very busy the last few weeks. I promise to post an update soon.

This looks like an awesome product. Can't wait to see it all in action. I like the "much less expensive" part quite a bit too.
 
I like the Spike design very much! Congratulations Jim, and the Red team of course.

I think that this camera can be used for 3-D work and compete with IMAX easily!

Watch out IMAX, you won't be the only King of 3-D in the future!

Thanks,

Why is dust a problem?
No different than any other removable lens system including film.

Hi Rob,

In 30 years of changing lenses on a film camera I never had dust on the 'sensor', I have however had dust on my DSLR's sensor.

Stephen
 
its a bigger problem because on a film camera, if dust lands on a frame, it is pushed out of the way onto the next frame. You can blast dust out of the way with a canned air, your fine. Even if something big lands in the gate, like a hair, it gets pushed to the side and kind of out of the way.

On a digital sensor one tiny piece of dust stays put and ruins every frame. Canned air isnt good for sensors, so removing it is harder.

The best approach that I've seen for this problem, is the one found on Machine Vision Cameras (at least on AVT cams). And that is, to place the IR cut filter just where the threads where you mount the lens ends. This way dust never reaches the inside of the camera, including the sensor.

Thanks,
Cesar Rubio.
 
Use the same cleaning methods as you do with a DSLR. Sensor brushes or swabs etc.

Erik, this is exactly what I need, one for focus, one for aperture and one for zoom.

When, and I don't ask how much:-)

any chance of getting the image stabilizer to work on a Canon EF?

Hi Ceaser,

I get it. I thought you were refering to the mounts that will be used on the Red camera.

Actually I made the comment, to see if the Red team could implement something like that in the Spike & Red Cameras...perhaps in the future?

Thanks,

Hi Cesar,

Your the first one I've read here that has asked about a "C" mount for the Red camera. As I'm sure you know, the flange focal depth for this mount is .690" so that does not leave very much room to work with. If there is nothing in the way I would think a custom front end could be fabricated for this use. Also most, (not all) "C" mount lenses were designed to cover the standard 16mm format so I don't know if this is enough area for the format you intend to shoot. I wish I still had a machine shop as I would love to make custom hard fronts for this camera. Of course keeping in line with the beautiful styling of the camera itself.

Chuck:

C-mount lenses only covers 1" sensors size maximum. The Spike & Red Cameras, having a bigger sensor cannot work with c-mount lenses without "vignetting" the sensor image.

My comment was to see if its possible to implement the IR-Cut filter, just where any of the Spike or Red cameras lens mount ends. This way the dust problem won't affect the sensor or the inside of both cameras.

With Digital SLR cameras, to do this would be a little bit complicated due to the viewfinder flip mirror. But I don't know how difficult would be to implement something like that in JJ cameras.

Thanks,
Cesar Rubio.
