    For me the biggest difference is the future with VV and my main reason for going with the Weapon Helium. My guess is the Weapon will become a VV only camera and the Epic-W will keep the S35 Helium. So you then have the paths to choose. S35 Helium = Epic-W vs Weapon VV at say $60k. Then the price gap makes sense.

    Another thing to think about... I currently working on a alexa mini raw / cooke ana production and when image is squeezed to it´s 2880x1080 (full frame arri with ana) the image is covering a little bit more then the upper left corner on my consumer TV set.... For me to buy such camera today is nuts.

    I think this image says a lot. https://scontent-arn2-1.xx.fbcdn.net...3c&oe=588D6E6C

    A cinema camera that does not have enough resolution to fill out a regular home tv... I don't know what to say about that.

    I mix 6k weapon footage with the above and on a 4k screen it´s quite easy to see how great a 6k to UHD downscale looks compared to a 2880 upscale. But sure people like the alexa, personally I find it difficult to compare.
    Bjørn I would say you are mistaken with the Alexa resolution - Anamorphic Alexa 4:3 is 2880 x 2160. - so full 4k height.

    Sure then you stretch that out or squeeze it out, I think pushing the height to half / 1080 is the only way to not upscale no?

    The best approach is scale (5760)2880x2160 (actually cropped to 2582x2160 for 2:39:1 delivery) to 4096x1716 for DCI compliance.

    In your approach you throw away vertical res...and also you should factor OLPF strength... ;)

    I wasn't thinking of that. Definitely a good possibility to keep in mind.

    It's always good to look at everything to see the various differences between models. As usual I have a chart for such things:

    http://phfx.com/tools/REDDSMC2Camera...et2016_big.png


    Side note and on topic-ish thing. Epic Dragon and Weapon 6K S35 Dragon. Many have been working 5K-6K. 8K is indeed the new concept many are exploring. Helium sensor tech results in 7K being around Super 35mm in width, so I think for those shooting 5K say on Dragon, you may find your comfort zone around 7K Helium. Unless you're target delivery is 8K, then for sure shoot 8K.

    There are notable differences between the two sensor technologies on a per format basis. Some come down to resolution and format, some come down say image texture.

    Phil, your charts are awesome! Thank you!

And, if clients request Red from this point on they're going to want the Weapon Helium, hands down. Right now, my Dragon keeps chugging along and clients are happy with it, especially since 6k R3D files can be cut very easily now without hardware acceleration. I don't even transcode anymore. I just edit the 6k source files and everything works great.

    I kind of wish Red hadn't fragmented their line to this degree and pushed their top end camera into the $50k realm. If Weapon Helium sat a little closer to where Epic-W sat, they'd have my money in a heart beat. It feels like they wanted to position Weapon as close as possible to the Arri Mini in price. But I wish they'd stuck to that rebellious Red spirit and undercut them severely with their flagship camera. Most of my friends in LA sold their Dragons to purchase Arri Mini's. And those cameras do get rented out a ton. But had they been able to save $20k going to a Weapon Helium, I bet they would've done it. However, I'll be the first to admit that I am candidly spouting all this stuff out, with no real knowledge as to how much Red is spending on their backend in R & D and manufacturing. So it's probably easier said then done for Red to have just magically made the Weapon more affordable. The Weapon's current price point might be required to keep the company moving forward.

    The Epic-W is clearly the result of there being such a huge gap between Red's flagship camera and the Scarlet. There are a ton of customers like me that own Dragons, would love to upgrade but just can't justify owning the Weapon. The Epic-W fills that gap. Unfortunately, it is a camera that reduces some of the functionality that we as Dragon owners have all become accustomed to. This is Red's fault for making the Dragon such a bad ass camera at such a great price! I don't want to give up those frame rates! I've even searched around for other cameras on the market and there is just no competition when it comes to frame rates and image quality. Sure the Epic-W gives you a lot more in image quality, but frame rates are a really big deal for the work I do, and they may be the one thing that keeps a Dragon in my hands right now. Perhaps I'll just keep on saving for a Helium and by the time I've got enough Red will have announced a new body with ND's.
    I'm in the same boat as you! But my Dragon was stolen a few months ago and now I have to make a purchase pretty quickly in order for my own business to keep moving forward!

    I had my concerns but a couple of things

    Firstly i guess it depends where you're shooting, in PAL land it's 25p or 24p here so 8K WS is 38fps which is off enough to make it slower. Then 7K is a bit slower too (43)

    At 6K clearly that's where it happens, 100fps is no problem. And to be honest any slower than that and you're in an odd territory (for me anyway)

    Then FOV depends on the lenses. I have a bunch of contax primes, with 18mm my widest but that's not ideal. I have M mount lenses down to 12 but they're not going to work (such a shame as they're so light and perfect)

    But i just got the 12-24 f4 Sigma and the 24-35 f2 sigma. Both seem like awesome lenses and 12mm f4 puts me straight back into wide enough for all but weird shots.

    Mind you the 12 24 is huge, wasn't expecting that.

    But 6K with a combination of ultra wide lenses and i'm a happy bunny on that front.

    cheers

    Have you tried the M mount lenses? is the problem coverage? I have been shooting 6K weapon M mount. Please do tell me more....
    I've got a black belt in keeping it real!

    I don't see it as I throw pixels away when I downsample. As it improves noise, sharpness etc. And dubbling the horisontal pixels is quite the opposite of that. But sure if you need to make a 4096x1716 or what ever format that is bigger than what the camera can capture than thats the only way.
