Will Canon 70-200 support up to 4k 5k 6k before it vignettes on Scarlet?

[Colin Sheldon]

I think your mistaking what I am talking about. I am talking about FF5K/6K coverage. On the chart you provided the image circle needs to be 43mm+ to cover and only the CP.2's and the longer prime lenses cover that size. Of course shooting 2:4:1 or within a 16x9 frame will cover a wider range of lenses, but I'm talking specifically about covering the FULL FRAME Sensor in FF Mode.

So in that, the new slightly larger sensor in FF mode will require slightly more than 43mm+ to cover the FF mode of the sensor. S35, no worries...

"FF5k" isn't the same as FF35. "FF5k" is just using the full 5K MX sensor.

When you look at actual sensor sizes you find:
The 5DM2 (FF) - 36mm x 24mm (864mm squared).
The R1 M (S35) - 24.4mm x 13.7mm (334.28 mm squared)
Epic MX (S35) - 27.65x14.58mm (403.1 mm squared)
Epic Dragon (S35) - 30×15.8mm (474mm squared)

So as you can see, an actual FF sensor is basically twice the surface area of the new Dragon sensor. Red does not currently, nor have they announced any release dates for, an actual FF camera. All of Reds cameras now and for the foreseeable future are S35.

Well, Jarred loves - and apparently most often uses from what I've read from him - the lens we are discussing here so I'm sure all is well as far as image quality is concerned though Canon has stated they are re-designing their professional lenses for use with higher resolution sensors ala their Cinema EOS system based on user feedback.

And that confusion is why I'm always ranting about lensmaker marketing departments saying "covers 5K" as if the number of pixels on a sensor has anything to do with its size.

My whole point is to say....FF LENSES WILL WORK WITH DRAGON + WHATEVER COMES NEXT. They are made to cover a larger image circle which future proofs them with RED for the foreseeable sensor lineup. Sure Most S35 lenses will cover for the time being, but if the sensor size becomes FF rather than s35 in the near future, your investment choices become more important. Sure there will be s35 windowed versions on a FF sensor, but again, by that time most people will want the larger FF image for vfx, stabilization, reframing, etc. I'm speaking merely in terms of investment. If I as a DP had to choose lenses now theres no doubt I'd choose Master Primes. They are my favorite lenses ever made. But were talking about Canon lenses and covering Dragon and future FF sensors.

Thanks for the quick reply. been really thinking about that 100mm Macro too. Seen many really like that 24-70 too.

As for a filter, which would you recommend for these (I assume they are all 77mm)? for both UV and general use?

Not all Canon L lenses are 77mm, e.g., the 16-35mm 2.8 L for example is 82mm, ... same for the nicely sharp TS 24,3.5 L. I have tested them on my Scarlet with a single 77mm filter (and a reduction 82 down to 77) no vignetting at 5K. But do your own tests. Vignetting based on limitations in size or glass might be needed to differentiate here ;o)

The Canon EF 100mm f2.8 L IS USM macro lens is nice. Its image stabilisation is good for handheld filming as well. The 70-200 f2.8 L IS II USM lens is another great lens. Very sharp. Yet to test the new 24-70 f2.8 L II USM (production version not yet available).

Do you need lens support at all time for the 70-200? I have aluminum Canon mount, if that makes a difference..

I'm not saying it is the "correct" answer.. but I never have. Not once. Our mount with the lockring locked is about 100x more secure than any mount you will ever find on a canon.

As for filters:
I'd just buy UV filters for each one and leave them on permanently like a scratch shield. Then I'd get a polarizer, nd .3, nd .6, nd .9 , nd 1.2. and those should cover you 99% of the time.

Be alert when using a screw on UV filter. If you put that into a matte box and slide other glass on in front of it, you are likely to introduce interior reflections and lose contrast. Keep your UV in front of the stack.
