Over the last couple of months there's been a fair amount of skunk works tests involving the RED Weapon 8K.

For those of us destined for 8K, Lens Coverage has been a question mark and a head scratcher as the 8K FF Weapon sensor is considered VistaVision+ and a hair outside of the well known FF35 3:2 standard image circle.

But the news is pretty good when it comes to...



First up we're starting with Modern FF35 Lenses (meaning stuff that's built and sold today) as well as a few 65mm lenses that have played a role in recent camera tests.





Some Notes and Thoughts
- The focus initially is FF35 and 65mm glass, but S35 glass will be tested as well as some of the longer lenses in particular will cover.
- Something to note, the 8K Weapon camera does use a new RED 8K PL Mount. The flocking and opening are larger.
- Bare with me. There's a few decades and a few hundred lenses to test.
- Coming soon? Leica-R, Canon EF Zooms, Olympus-OM, Contax Zeiss, Nikon, etc....
- I'll keep this chart for the time being topping out around 200-ishmm. Pretty sure most 300mm primes will be fine.
- For lenses like the Zeiss CP.2, Canon CN-E, and Rokinon their more "still minded" brothers have similar designs and coverage should be the same, but might not be.
- For lenses on the edge of coverage, do remember we're a hair outside of the FF35 3:2 image circle and there's a great deal of copy variation particularly on still glass where some lenses might not cover.
- You can expect all designed for FF35 lenses to approximately cover 7K FF and 7.5K HD as that's relatively safe.


Here are the Maximum Image Circles for the 8K Weapon and certain relavent formats:





Many thanks to Jarred, Brent, and Michael at RED as well as Matt from Duclos Lenses.

There's a lot more work to do, but this is a great start. If you have lenses you need coverage tested on let me know. I have or have access to a great deal of what needs to be tested.
 
Amazing! Thank you!
 
This is a fantastic start, Phil. As always, thanks for all you do and your invaluable contributions to our knowledge base!!
 
Damn yeah! Much love to Phil, Matt and the RED team.. great to see this info in advance to make some smart choices on lens acquisition for the future. Well done.
 
Thanks Phil, bummed to hear the 15-30 compact zoom isn't covering at the wide end cleanly. They've been touting it off that it does. I can bring a set of summicron-c to test if you need those.
 
Great stuff Phil! Thanks for all your time, look forward to this lists future updates.

Questions:
Did you use a PL to 8K PL mount adapter or did DUCLOS adapt the rear of each lens for you?
What is the new 8K PL mount flange depth please?
Does the new mount have the great lugs like the new PL WEAPON mount does?

Lots more questions but I'm aware of how busy you must be.

Thanks in advance, Stu.
 
I doubt s35 lenses will fit at all, the real question for me is outside of vantage hawk and Panavision what's the best set you can own and keep? It's interesting that only the entry level PL sets cover.... I been messing with them lately in case they covered so glad to know finally for sure!

cp2s felt real nice to me vs xeen but I gotta try canon and schneider plus sigma art and otus. Wonder why they are so sought after as still glass and if Otus really is better than cp2? I can't wait for macro 8k
 
If you own a Weapon 8K and you crop the sensor down to 6K, is the coverage identical to the current Dragon or is it different? Also, is the depth of field different than the current Dragon at 6K? Theoretically it should be the same but you never know with these things.
 
Identical, same with going lower equates scarlet or Raven. 6k with same pixel size and FOV is what I heard but ain't try it myself yet. Dsmc2 has added utility by better image, no orbs, smear, ADD, proxies and LUTs, it's way better in many ways but same FOV unless you go 8k

No worries Stu. I'll be home later today to fix that typo that Ketch pointed out, but to answer a few questions.

All of this first round of glass tested was PL Mount using a rather early RED 8K PL Mount. The flange depth is the same as all the RED PL Mounts, however, the flocking design and port are optimized for the 40.96x21.6mm Weapon 8K sensor. I would expect the new final design of the Weapon 8K PL Mount to be similar to the Mg PL Mount for 6K. Captive bolts, grip protrusions on the locking collar, likely Magnesium in material.

6K should be same across all Weapons. 8K Weapons just have much larger cut of SAME sensor (almost twice as large).
 
I think one of the most important types of tests at 8K will be fall off. The difference in vignetting btw FULL FRAME glass at 8K....and MEDIUM FORMAT glass at 8K (where you'd be shooting through their SWEET SPOT).

I have a modded set of Contax Primes and Hasselblad Primes, and this is something I'll be looking very closely at.
