Scarlet 2/3rds fixed and DOF adaptor

[Henry Olonga]

I was wondering if anyone else has thought of still using the Scarlet 2/3 rds with an SGBlade or Letus ultimate etc. Certainly save some money on the big boys and get a 'similiar' FOV. I know some feel that the train has moved on to Larger sensors.

For the bottom of the price range indie - I can see some advantages

The Fixed Scarlet 2/3rds is much cheaper, small and light and can be a 'take it anywhere' kind of camera with a useful zoom. Discreete enough to be inconspicuous as well.

One of the cons is that it doesn't give the 35 mm look. So I was wondering - will my DOF adaptor still have some work left in it? Perhaps not for the high frame rate stuff but for the 24p medium shots. I am intrigued. The Scarlet will no doubt have better low light than the EX1 and I have seen some wonderful images done in low light with that cam and a DOF adaptor.

This makes the modular concept even more expandable. Want that 35 mm softer look, stick it on - off for the crazy sharp look. The S35 scarlet will be way out of my price range and also has limited frame rates at the highest res.

Is this a nice compromise for the same FOV without the extra dollars?What do you guys think.:seeya:

I've read on another thread that the fixed Scarlet will be something like a stop and a half or something like that FOV-wise so you can manage to have some kind of shallow focus if you want to.

But good question.

 

[Gabe Conroy]

I feel like it's a little pointless since once you've spent all that money on adapters and stuff, you probably could've just bought a Scarlet S35...

 

[Tim Hole]

I agree with Gabe, although you do mention you already have an adaptor there is no harm trying it. I am however very dubious about it. It is likely to soften the image and degrade it so much that it might be pointless shooting on a scarlet (minus shooting raw). It depends very much on what type of adaptor you use and the lens you put on front of it. If it is a cheaper SLR lens it won't resolve anywhere close to the level the scarlet can, thus soften it even more.

Using a 'decent' adapator, like Gabe pointed out you may as well buy a S35.

The answer is possibly, there is one guarantee though...someone will definitely try it.

 

[Bastien Tribalat]

And IF S35 ships early 2011 (before April Jim said), anyone who really want to use 35mm lenses and have a shallow DOF should wait until there...

And... By the way... It seems obvious that type of SCarlet sensor can have a better resolution than an SLR sensor so... What do you think about using Zeiss ZE or ZF series on Scarlets ? These lenses would be good enough ?

 

[Tim Hole]

They are very nice lenses. I'd prefer to lean more towards the Zeiss-CP range. They are pretty damn good for the price but are still a premuim on top of the ZE/F range. Its definitely the right ball park to be in if you were planning on doing it.

 

[Jaime Vallés]

Practically any modern SLR lens will have more than enough resolving power for the 2/3" Scarlet. Heck, most any modern SLR lens will have enough resolution for the 5K Epic!

Any softening will be primarily due to the DoF adapter used, not the lens.

 

[Andrew Rieger]

I think some have also raised concerns that the Scarlet is too high resolution to use a DOF adapter and that the ground glass pattern will show up even if you are using a dof adapter with a spinning ground glass.

 

[Franck De Togni]

Yeah I also think DOF's adapters are made for smaller sensors with smaller resolution.

 

[Andrew Rieger]

You would need a ground glass that can handle the resolution. I am sure there are some but I think there were some tests with an SI2k a couple of years back that showed that current consumer adapters are not suitable for higher resolution cameras. I guess we won't know till someone tries it.

It takes higher resolution lenses for the higher pixel density 2/3" Scarlet than it does for most 35mm cameras.

 

[Henry Olonga]

So this is basically a bad idea then?

 

[Tim Hole]

Don't know till you try it!

 

[Aaron Newsome]

So this is basically a bad idea then?

I say it's probably a bad idea in most cases. I have a 2/3" camera and I've never felt I needed any shallower depth of field. If I want my subject to stand out and the background to be blurry, I just chose the right lens and distance to subject to achieve the look I want.

I've never felt I needed a DOF adapter at all..

 

[Ryan Farnes]

It takes higher resolution lenses for the higher pixel density 2/3" Scarlet than it does for most 35mm cameras.

But on a DOF adapter, the projected image from a 35mm lens is on an intermediate surface. So the resolving issues are [EDIT] relevant to the "resolving power" of that surface, right? A 35mm lens should provide more than enough detail I would think. So it just comes down to whether or not the surface becomes an issue due to the 3K high fidelity image from the Scarlet.

Are you referring to sticking 35mm glass onto a 2/3" cinema Scarlet? I can see how that would be a bad idea except with the most precise lenses that you really want to crop by a factor of 3 or something.

Fixed Scarlet opens up to f/2.8 if I remember correctly. What is the fastest lens you can use on your current 2/3" cam?

This is why I'm eyeing the 2/3" cinema Scarlet myself. Shooting wide open at f/1.4 with a mini-prime will be like shooting at a half stop between f/2.8 and f/4 on my 7D. Fixed Scarlet is like f/5.6 on S35 sensors.

The zoom lens I own is f/2.0. I've used Zeiss Digiprimes on a few features and they are T/1.7 if I remember right. These lenses are optimized for shooting wide open too. Dof is plenty shallow when you need it.

Fixed Scarlet is T2.4...

 

[Justin O'Neill]

Fixed Scarlet is T2.4...

Actually f2.4 is the f-stop:

Lens is F2.4, T2.6. (And Incredible)

Corrected I stand.
