    truth about Pocket 6k dynamic range

    In: Cameras

    Posted

    'Die Blackmagic Pocket CC 6K konkurriert mit der älteren und teureren Ursa G2 aus dem gleichem Haus. Diese neueste Pocket ist spärlicher ausgestattet als die Ursa, gefällt aber durch etwas verbesserten Dydamikumfang und kommt, dank Ihrer dualen nativen ISO, deutlich besser mit Lowlight-Situationen zurecht. Auch die Ursa zeigt in den Schatten einen deutlichen Drift ins Grüne.'

    Google Translate

    'The Blackmagic Pocket CC 6K competes with the older and more expensive Ursa G2 from the same house. This latest pocket is less well equipped than the Ursa, but pleases with a slightly improved Dynamic range and, thanks to its dual native ISO, copes with lowlight situations much better. The Ursa also shows a clear drift into the green in the shadows.'

    Whoever did this test seems to agree with you.

    On a side note, great job Panasonic, results look fantastic.

    My first indication was @Juan Melara Alexa Powergrade thread. He tested it against the Alexa and found the P6K had more highlight information. Then I saw someone posting how the Pocket 6k has more dynamic range than the RED helium. 

    Could you link these videos and I’d love to see your tests! 

    I think an issue is that some companies are very liberal about the DR numbers On there cameras. I recently saw someone share a DR chart of the BMMCC that looked very similar to the Helium/Komodo chart that Red released, which have wildly different ratings (13-16+)
     

    Your findings comparing the 4.6k and the 6K are interesting, I wonder if the higher resolution is helping the low end quite a bit. I do wonder how my 4K compares aswell.

    This may help - in the second half of the video he demonstrates changing the mount (and de-clicking): youtube.com/watch?v=EUjUxKvXgpw

     

    Thank You, I've got a live stream saved from Duclos doing the same conversion, it looks simple enough but there's plenty of opportunity for mistakes.

    I'm starting to build my my Contax Zeiss MM set.

    I started with the 35mm F2.8 and have since added the 28mm F2.8. They actually match very closely despite being quite far apart in serial numbers 35mm (79xxxx) 28mm (69xxxx). To my eye, there's no difference in sharpness. The 28mm was slightly brighter at 2.8. I had to adjust exposure offset wheel -0.2 in resolve, a very minor change. This might be because the lens is older and has a bit more dust in the optics bringing the lift up a bit? They handle colour very similar, I didn't need to make any adjustments to temp or tint. They would be very easy to cut together. When I matched the frame size they were almost indistinguishable in an AB test. 

    I was planning on getting lenses with similar serial numbers but I found the 28mm at crazy good price. I'm not so bothered about that anymore after seeing how closely they match. I will say the 28mm's aperture ring isn't quite as satisfying as the 35mm. The focus rings are both very smooth and similar though.

    I temporarily had the 50mm F1.4 MM (82xxxx) but had to send it back because it had significant separation and fog in the lens. It really messed up the lens when there was a light pointing down it. Even though the copy had severe optical issues, it was razer sharp at F2.8 and very good at 1.4. I didn't measure it in depth against the 35mm but the colour and contrast seemed to match very closely at 2.8. I will be looking for another copy. 

    When I can build enough funds, i'll also be adding the 85mm F2.8 to the kit. The 25mm F2.8 also looks to be a very interesting lens but i'm not sure I can justify something so close to the 28mm

    I've already got Tilta seamless Focus rings (£2 each!) and front and rear caps for 4 lenses. 3 Leitax EFmounts have been shipped and are on their way here now. Im not bothering with step up rings, im going to take advantage of cheap 55mm filters.

    If you can get a good deal or two a set of these can be quite cheap to put together. The 28 & 35 have cost about £250 each (including Leitax adapters) and I predict the 50mm and 85mm to cost about £300-330 each to fully kit out.

    Fingers crossed I don't mess up this mount conversion when they arrive.

    I'm currently putting together a set of the smaller, more uniform Contax Zeiss Lenses, I'm going for the 28mm 2.8, 35mm 2.8, 50mm 1.4, 85mm 2.8. (all MM)

    You could add the 135mm 2.8 if you want something longer, its really cheap... Although It can get expensive if you need the wider lenses. 

    They might not be a fit for you as you like larger lenses. 

    Part of my reasoning for choosing these models is that they are all really well built, fully metal and have long focus throws. They all have a 55mm filter thread, Similar in weight (+-30g) and they are very similar in size. They also all have the same speed. (I'm treating the 50mm as a 2.8, as i've read its slightly soft wide open and the others are quite sharp, so it'll match better.)

    So far i've got the 35mm with the 28mm on the way to me and found them under £200 each, I've seen the 50mm go for a similar price and the 85mm go for slightly more but Ill need to get some more work in before I pick those 2 up haha. 

    Include Leitax conversion mounts into your budget though as those cheap adapters are as good as useless. Mine are on the way now.

    Tilta sell seamless follow focus gears in all sizes for £2.50 each! Haven't tried them yet but can't go wrong at that price.

    You could convert them all to 77mm but my plan is to keep them all at 55mm and take advantage of the small size and really cheap filters.

    Looks like the first colour is shipping on Friday, kinda crazy that these will be shipping to customers with barely any released specs & very little sample footage... I guess the Red guys have a lot of faith in the product. At least it looks like the wheels are finally in motion for the camera to get in the hands of users so we can actually see some footage shot. 

    For me the interesting thing about this camera is that it has a global shutter and close to Helium's claimed '16.5+' dynamic range. It'll be interesting to see how it actually stacks up. The form factor looks great too, small but easy to rig.

    Just ordered 2 Leitax Adapters (spare one for the 85mm 2.8 that i'll inevitably buy) & The screwdriver Leitax recommend. Ive been told by Leitax it could be up to 10 days until dispatch & up to 2 weeks postage time... fingers crossed its a bit quicker than that! Hopefully I don't strip the screws. Would be very interested if anyone has any experience changing the mounts themselves, Simmod lenses recommend heating up the screws with a soldering iron before unscrewing to melt the glue... time to source one of those I guess haha!

    Just picked up a Contax Zeiss 35mm 2.8 MM for a great price on eBay. Will post some sample images when it arrives! Anyone have any experience with the F2.8 Contax Zeiss set? Will likely try to build and cinemod out a set if I like it...  This good deal could end up costing quite a lot haha

    The Tokina is the lens I always seem to go back to. I think this is my 3rd copy, I'll probably never let it go again. I paid much less than £200 each time. I sold the Sigma zooms because I rarely used them after my most recent copy.

    Mechanically it's a dream at its price point. The lens doesn't extend and the focus ring has hard stops. It would make a great cine-mod lens. It also has a short throw, good for handheld pulling. The zoom ring is quite stiff, you won't be zooming mid shot.  It feels well built, it'll survive a few knocks. The AF system seems to be broken on every one of these I've used, but that usually means they sell at a cheaper price.

    Optically, it's not the sharpest lens in the world but also not noticeably soft even wide open on a SB. This is where I sort of miss the sigma zooms. It also doesn't focus very close (0.7m) 28mm on the lens really sings when filming people, really wish I could get a bit closer. The lens also isn't par focal, but its not far off, it only needs minor adjustments. Breathing is very well controlled. On the wide end, the lens distorts a touch more than a modern lens, but I quite how it falls off.

    The lens flares really change through the focal length, I always experiment with the zoom when there's flares. Around 35mm if one of my favourites, you get some cool thin red rings. The lens flares very easily, I like it for narrative stuff but always have some black wrap or gaff tape on hand for corporate shoots.

    It's such an all rounder zoom lens to have in the bag, just enough character for narrative work but can also clean up when it needs to.
