  1. I do not understand your obsession with video on stills cameras. Video is an added feature on a stills camera so how can you compare them to a BMCC that is made purely for video? Stills cameras will always be stills cameras, the video will get better as the tech gets cheaper but it will never be the main focus. We are a small market and will be treated as such.

     

    You miss the whole point of the article and so typical of stills photographers....

  2. 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.

    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 :)

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

  5. Personally I wouldn't trust an C-Mount lenses for full HD work.  They are simply not good enough, and this will show the more people start to use them.

    Sorry but you are wrong and that is your opinion. People buy a CINEMA camera and then want to use clinical oversharp lens and they result in a 'video look' is pretty pointless!

     

    Before righting off all C mount lenses, I'd suggest you listen to what others are experiencing in a positive light. I can certainly vouch that the several HIGH QUALITY C Mount zooms used on 16mm and Super 16mm cameras in the past even surpass old B4 ENG lenses.

     

    Also pretty pointless is your suggestion of using FULL FRAME with a 3X crop lenses for the BMPC! The M4/3 Speedbooster or any of it's cheap chinese contemporaries at this time do not exist for purchase. Some of the C mount lenses have as much fine glass and elements in them as much as the "decent 1960's-1980's MF lenses from Zeiss, Nikkor, Olympus, Canon." you suggest as many were made by them!
