  • 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 :)

RPAs...

Oh this would be a good time to remind RED....

Hey. Red. How's it going? You're making a beautiful full format sensor and you're putting it in a delightful little package called the Scarlet FF35. It would really help your anamorphic sales pitch with these lenses if you added Anamorphic Desqueeze to the Scarlet line too. Just saying.
 
What a fun surprise. How many years has this been? Fun.

Nice! RPP, RPA, RED Rocket™™™...

Any plans for RPGs?

I swear I didn't photoshop this...
 
Jim/ David,
I don't know if it's physically possible, but RED is making some amazing stuff so here's my idea! If all the glass in the lens was designed to cover FF35 (36x24) what is the possibility or limits of designing the lens with a switchable Anamorphic element (if it was a font element it seems like it could be possible) So you could start out with an anamorphic element that covers the 16x9 area of the M-X, but in the FF35 future the font element could be switched out with one that covers the full frame. (of course for a small fee:)) That way, just like RED cameras, the lenses are also future proof. Obsolescence is obsolete!
 
I don't buy this S35 obsolete versus FF35 future-proof stuff. It is like saying future is only for sports cars. I think they both serve their own purposes, but happily coexist. I think S35, just as 2/3" are here to stay for their own merits.

The reason I mentioned FF35 is because this size would be more compeling for 2x anamorphic. Having said that, I do not think you can make a piece of glass like this under 10 kg, so I don't think this is going to fly.

So, I'm curious on the details. Either way, there does not seem to be much choice of anamorphics at present, so it is a welcome move any way you slice it.
 
Your right every format has it's purpose. But for me personally, I've been looking only at FF35 glass, because I know that when RED releases a FF35 sensor it will be another incredible jump in image quality, dynamic range and sensitivity. That's just what happens when you have bigger photosites, so I want glass that will cover it, and if you had an anamorphic lens that would cover FF35, you wouldn't throw away any of those beautiful pixels in order to have a widescreen release, as you'd have to crop the top and bottom with aspherical lenses. And I'm not really thinking a simple screw on front element, but designed inside the lens itself, but in a way that only RED could switch out for a fee, or any good lens tech.
 
The great thing about a FF35 sensor though is you don't have to use all of it. And since RED is developing the sensor and the lenses. They could find a happy sweet spot between FF35 and S35 so that the lenses can be used on both then offer a sensor crop for the FF35 to get the full 1.33
 
I'm not a lens tech, so I don't know if it's optically possible or sufficient in terms of image quality and lens speed, but I thought it was a cool idea anyway.
 
That's true, but there would definitely be a compromise with both sensors then, because the optical squeeze for a 16x9 sensor is less then it would be for a FF35 sensor. Thats why the idea for an internal switchable element with different squeeze ratios.
 
If it was a front or even back element it seems like it would be feasible, especially if the lens is designed from scratch to be able to do this. Remove a few small screws a few retainer rings and voila the element is free to be changed out! Or course by a RED certified lens tech! :)
 
Of course I already have a patent on this idea, so all I ask in return is a free set of lenses when they get made! Hehehehe:thumbsup:

Tonight we are announcing the development of the RPAs (RED Pro Anamorphics). They will match color, optical quality and mechanical performance characteristics with their little brothers... the RPPs. The weight of the RPAs is expected to be within 1/2 pound of the RPPs.

Initial set will consist of:

35mm T2.4
50mm T2.4
85mm T2.4
100mm T2.4

A 25mm T2.4 is also being studied.

Delivery of the 4 lens set is expected by year's end... although you know the schedule drill.

Prices will be slightly higher than RPPs.

Fantastic!
 
This is just pure speculation from my part and I'm definitely not an optical engineer. The only specs besides focal lenghts that we have from the RPAs is that they are T/2.4 (which could be around f/2.1). RPP are T/1.8, which could be around f/1.7.
2.1 / 1.7 = 1.24, could this give us somekind of hint what the anamorphic squeeze-ratio might be?
2:1 aspect ratio squeezed by 1.24 gives 2.48:1, so maybe these lenses are designed for the M-X sensor.

On the other hand if RPAs are going to be front element anamorphics, which if I've understood correctly is similar to a wide angle converter in front of the lens (similar to a converter that widens only horizontally). I think these converters doesn't affect the f-number of the lens and the anamorphic elements alone woudn't probably make the t-number to go from 1.8 to 2.4 so maybe these new lenses aren't based on RPPs but some totally new design.

Please correct me if I'm wrong, which I really likely.

The third option is what the Hawks do, put the anamorphic elements somewhere in the middle of the lens.

That information can also be find at cinematography.com too, but in a recent demo, Vantage said their lenses are front anamorphic and complained about the info posted online saying the anamorphic element is in the middle.
The Vseries indeed looked like they had the anamorphic lens in the front.
 
If the new announced lenses are just x1.3 then they will almost look spherical (x1.3 does not introduce the characteristics of the anamorphic lenses that we are all expecting). If they are x2, then we are going to need longer lenses. A 100mm is just too short. We´d need at least to get to the 200mm range in order to have a small lens set.
 
i hope 2x and horizontally lens flares, with hawk they were eliminated and you need a streak filter...with anas it would be totally cool for me noz to use the full sensor....or will there be a square sensored epic? called epic A ?
