View Full Version : 35mm Adapter with 2/3" Scarlet.

A good friend has got an M2 converter from redrockmicro and I can use it if I ask him to.
I know there have already been a lot of discussions about Scarlet and DOF and these converters.
But I think my question is a little bit more specific than the ones we already had:
Should I use (in the case that I wan't to have more DOF) the 35mm converter together with the Scarlet 2/3" (fixed or with interchangeable)? I have never worked with a 35mm converter so this question appeared to me.
I think buying a converter wouldn't be useful as many of you stated in the discussions months ago. But what about using it when I got one in range?

I'm actually quite currious concerning the possibilities of using a 35mm converter together with the fixed lense Scarlet 2/3". If that would be possible (and of course with a certain loss of light) then using the nikon/canon lenses already at this point, wouldn't make the upgrade to the S35-version as expensive, since you would already have everything else, except for the 'brain' (of course with other ongoing upgrades).

The answer isn't so simple. If you will always want less (shallower) DOF at any field of view and can live with lower frame rates, the new, modular Scarlet system's S35 sensor option will yield better image quality at a cost competitive with that of a combination of 2/3-inch Scarlet, DOF adapter, and relay lens. If you're borrowing the adapter, the 2/3-inch option will be cheaper. And if the DOF adapter companies devise cheap, simpler, high-quality relay lenses and adapters to better compete in a world of S35 and FF35 Scarlets and dSLRs capable of decent HD video, inexpensive, easy-to-set-up adapters may become a very viable solution for those occasionally needing shallower DOF.

I was under the impression even the 2/3 was going to yield pretty shallow dof, no?

It's pretty shallow just search on vimeo for 16mm (which is pretty near) projects or even 2/3" .
I think the danger with adapters when shooting at these resolutions is the amount of detail it will pick up in the ground glass. Another potential issue is getting high enough quality achromats for the lenses.

Another potential issue is getting high enough quality achromats for the lenses.That's why I said the "S35 sensor option will yield better image quality" -- all other things being equal, of course.

I guess there will be also an option to put an 35mm adapter on the mount, for use with 35mm lenses, but I think I'd rarely use that.

An example, don't know the details of what it was shot on etc...

well it is a improvement over my 1/3 sensor lens, the background looked sufficiently blurred. But I would like a little more control over depth a field. I reallyto rent a scarlet for a day and see how good the video is... I am a bit uncertain as to which direction I will take next year. Hopefully I will have more choices by summertime.

Shooting with an adapter on the front of it, on 3k... its going to look terrible.... you will see the grain, it just won't be pleasing, and a lot grungier, than even the most "I <3 Grain" buffs with look away...

Should be interesting, I've seen Ultimate footage on an HVX and EX1 and I didn't find the grain distracting. I couldn't even really see it. I'm sure that once cameras are out that the adapter makes will make adjustments.

Well, what's the price difference? $2500 for 2/3" Scarlet brain + $4500 Letus Ultimate = $7000
or
$7000 for S35 Scarlet brain, no need for 35mm adapter. I'm sure this will yield way better image quality than using an adapter on 2/3" Scarlet.
Of course, there are less expensive 35mm adapters out there, but will their quality be sufficient for 3K resolution? We're just going to have to wait for real-world tests.

I think the best advice, which I havent seen yet, is to test when they're available. If you're able to barrow the DoF adapter, check the 2/3" system out and see if it meets your needs - then try with the DoF adapter to see how that works for you.
Assuming these bad boys will all be available at retail outlets, you might be able to find one local to you and play with it before you buy - or find a rental house that will rent one to you for the day so you can see the differences.
Ultimately, the cost will be the same with 2/3" + DoF adapter vs. S35 scarlet to begin with. So if it's something you think you may need, I would go with the S35 and avoid the adapter.

I'm new to this adapter scene. If image detail is not of the highest concern than I can imagine a cheap adapter on the 2/3" being "good enough". What I like about the many adapter video's out there is the softer look in deep DOF shots.
Does anybody know if you can use an adapter on the 2/3" interchangeable? Because there are cheap adapters for around $1K and if $2.5K for the interchangeable Scarlet 2/3" + $1K for an adapter can get me the look I need plus provide an easier upgrade path to the S35 I might go that route.
Sorry if this sounds noob, but if you can attach an adapter directly to the 2/3" interchangeable, do you still need a flip module or function to see everything correct on the camera's LCD?

Adapters are made to work with the normal lens mounted to the camera. So you would at least need a prime lens on the Scarlet for the adapter to work.

P+S Technik make an adapter to mount straight to a B4 mount. It is the adapter of choice for most broadcast productions.

However it comes with a very high price tag.

I think people will be quite happy with the depth of field once they start shooting on it. Plenty of TV shows were and some still are shot on 16mm. It's not uncommon to still find it on high end productions and fairly common in indies.

I know I am new here, but I feel that we cannot really speculate on what will and will not have good Depth of Field etc, until RED show us some footage with information on what Lens they shot it on, with which Scarlet Model, on whatever settings.
The images I have seen released are very nice. I think they were done with the S35 Scarlet, right?
I don't know what lenses they used though.
David Gray

Depth of field is not so much a speculation more of a science. It can be worked out via an equation.
We know the size of the sensor so we can easily work out the depth of field with a given lens. Obviously it isn't totally accurate measurement as sharp focus doesn't suddenly stop and start; but it will give you a good idea of focus range.
The depth of field characteristics will be very similar/exactly the same as current 2/3" cameras.
This is why depth of field tables are available for 35mm film in such publications as the Cinematographers manual. It is really only effected by the size of the circle of confusion of the lens, focal length and aperture.

Almost 17000 Euro's! That's an insane expensive way to use 35mm lenses on a 2/3" sensor. I'd rather wait till I can buy a S35 rig :thumbsup:
I'll be very happy with the Scarlet 2/3" DOF capabilities. I was thinking about the capability to use 35mm lenses without getting a cropped view.
I Just checked the conversion rates. 7000 USD = 4998 Euro's. If it stays that way...Screw the 2/3" :devil:

Thanks for pointing to that thread Kyle. It answers my question. This could be very good news for 2/3" Scarlet users.

I can agree with you on that note,
Once i get rid of my adapter, im never going back, im going to make due with what i have

I have only used an adapter once, it was on a recent shoot. I'll shoot most of my stuff like I do now, without an adapter, but they can be handy for some projects. If I decide to go for the S35 however..
It all depends on the pricing of Red's other stuff. I hope they'll come up with some news about their pricing so we can start planning things a little.
