Eagerly awaiting your Pocket Cinema Camera? You already have a micro for thirds camera and some C-mount lenses? Want to know if they will cover the sensor of the Pocket? Lets find out! I hope you will

Hello,   This is my very first post on EOSHD (although I’ve been following this blog for several years). I’m Antoine, I live in Paris and I’m 21 years old! (I would like to apologize for my

Hello Julian, great idea, very informative!   For all those who would like to try some old lenses on the BMPCC, here are my lenses between 10 and 16 mm. None of these is younger than 30 years, most

Anybody considered this lens? Some are M42 mount so ideal.

Here's more information on the Meteor 5-1 17-69mm f1.9 zoom, for anyone who's curious:

  • It's optically a pretty decent lens, especially when stopped down.
  • Its rear element protrudes deep into the camera body. This is not a problem for MFT per se, since M42 has a greater flange distance, and M42-to-MFT adapters have exactly the length of the protruding element. (I.e. the element doesn't protrude from the adapter anymore.) However, you need an M42 adapter that is a "clear tube", i.e. has no obstructing rings or other mechanical elements inside. The first adapter I had didn't qualify, a second one I bought (no name product, with the lettering "42X1M-m4/3" on its top) did.
  • I took test pictures at 17, 20, 25, 32, 42, 50, 60 and 69mm (the focal lengths marked on the lens' zoom lever) and at f5.6, with a Panasonic GX1, cropped the center to 3301x1857 pixels to obtain BMPC sensor-equivalent images, and converted them to 1920x1080 pixel jpegs:
  1. 17mm
  2. 20mm
  3. 25mm
  4. 32mm
  5. 42mm
  6. 50mm
  7. 60mm
  8. 69mm

Looking good. Thanks for sharing. Can you post a pic of the adapter you use? thanks :)

Hi , first post from me!

 

I have 2 wide angle lenses that I am currently testing on the BMPCC

 

ikonoskop  F1,7 9mm (the standard A-cam lens)  , I think its an Angenieux , but I am not sure

Kinoptik Tegea F1,8  5,7,mm  

 

I have bought this adapter

http://www.ebay.de/itm/C-Mount-Lens-to-Micro-4-3-M4-3-MFT-System-Adapter-/271167449658?ssPageName=ADME:L:OC:DE:3160

 

but the focus is way off, and  I am not sure if its the adapter or the lens

I can focus it if I unscrew the ring to hold the thread of the lens

if I get the lens closer to the chip they seem sharp and dont vingette!! : )

 

can somebody help me with a good adapter that works with theses lenses , or do I have to modiy the lenses or adapter somehow

 

thanks!

Just a personal conclusion: I've had the Blackmagic Pocket for two weeks and tested a large number of c-mount lenses from my collection on it, both classical 16mm cine lenses and cctv lenses. 

 

In all cases, I have found the c-mounts to be significantly inferior to native MFT lenses (such as the SLR Magic 12mm, the Voigtländer 25mm, but also the Panasonic 14mm and 20mm primes), even when testing top tier lenses such as the Schneider 25mm/1.4 or the Canon 13mm/1.5. Sharpness/detail is significantly lower, the image gets unsharp in the corners. The only advantage I see in those lenses is their compact size. In some cases, they can be used as speciality lenses (the Ernitec 6.5mm/1.8 as a fix focus fisheye, or a VT 8mm as a psychedelic wide angle with heavy vignetting and color casts); the 16mm/2.0 Tevidon is a decent performer with constant sharpness across the frame, but surely not as a good as an Olympus 17mm/1.8 or Samyang/Rokinon 16mm/2.0.

 

Unlike on the GH2, vintage glass doesn't look good on the Blackmagic Pocket. Since the BM Pocket gives an uncooked, non-artificially sharpened image with true organic color depth, it looks best with a good lens. A bad lens just looks bad.

But this is where grading comes into it. Adding sharpness, detail and contrast makes the difference.

Beg to disagree. You might, eventually, prefer organic sharpness and true detail from a decent lens to an artificially sharpened consumer camera-like video image.

 

I'd say that the Blackmagic Pocket camera is like a studio monitor speaker with clean linear frequency response - on which good recordings sound really good, but crappy recordings sound crappy (as opposed to consumer stereo sets that boost certain frequencies to make everything superficially sound good or at least fat).

 

But I had to learn this the hard way. Wouldn't have expected that I would be so disappointed by the results of the c-mount lenses and see such great differences to high quality MFT glass.

      For sale a rare 1937 Leitz Hektor Rapid 27mm f1.4 cinema lens (s/n 417161) for the Bolex H16 cinema camera. The lens covers full m43 sensor with a little vignetting and soft corners, great for cropped sensor of BMPCC, BMMCC, BMPCC4K (S16 mode). Examples of photos taken on a Lumix GX800 camera.
      The condition for its age is excellent: the case is clean with little signs of use, there are some dust and a bubble inside (this is typical of pre-war Leitz lenses), I did not notice the effect on the picture. The lens has been professionally serviced. A complete disassembly, cleaning and lubrication was carried out. The focus and aperture rings spin smoothly and effortlessly. The diaphragm is clean, 10 blades. The kit includes the original hood, front cap and c-mount adapter - m43 (MFT) with rear cap. There is focus on infinity. I will send the lens by mail worldwide.
      I shot this video with this lens Leitz Hektor Rapid 2.7cm f/1.4 on a Lumix GX800 camera: https://youtu.be/uIRKYGp6tg8

      Hey all, I'm looking to shoot a narrative short film with controlled lighting early next year and am thinking about shooting it on my original BMPCC...
      I know, I know. No 4K, terrible low-light, and horrible battery life. But if 1080p was fine, controlled lighting throughout, and an external battery solution, is it better for me to use the original and cancel my 4K pre-order? I could use the money saved to pay for an additional cine prime/actually pay actors a decent wage...
      What would be the advantages in this case of using the 4K over the original?

      C100 Mark II + Extra Battery (Original) + HardCase in perfect condition
      Price: 2800 + Shipping.
      I'm based in Spain but I can ship everywhere, shipping costs are around 50-100 and it will travel in the HardCase (included in the price) so it will be just fine :)
      This is the most reliable camera that I've ever used. ND's included, natural cinematic colors, Dual Pixel, amazingly detailed 1080p from an internal 4K downsampling process (made in camera), dual slot sd card recording, etc etc, just 100 % proffesional.
      I'm selling it just because I allways work with a cameraman which is fully equiped, so I'm not using mine enought.. ¡sadly!

      I'm looking to swap my Zeiss ZF.2 lenses for the equivalent Canon mountable Zeiss ZE lenses.
      Each of my lenses comes with 16:9 adaptors (which adapt the lenses to EF bodies, with de-clicked aperture and AF confirmation). 
      I have the following ZF.2 lenses: 21mm f/2.8, 35mm f/2.0, 50mm f/2.0 (Makro Planar), 100mm f/1.4 (Makro Planar).
