    Hi Catarina – sadly, the 12 minute limit on the 600D is not a tax limit, it is a 4GB limit in the EXFAT32 file structure of your SD card. Canon chose not to bridge these 4GB files to create continuous video recording capability. This is a trivial thing to do (they do it in their camcorders), but they chose not to do it in the T2i/550D, the T3i/600D, the 60D or the 7D.

    in later cameras, they allowed file bridging, but they capped it at 30 minutes in the EU due to the tax limitation. Out of laziness they have applied this same limit to their cameras in the rest of the world.

    Panasonic has taken a different approach. All of their still/hybrid GH cameras since the GH1 have bridged 4GB EXFAT32 files (just like their camcorders), so you can record for hours continuously (I have all four of these cameras, the GH1, GH2, GH3 and GH4 and I know this to be a fact).

    European versions of these cameras are limited to 30 minutes because of the EU tax limit – but Panasonic cares enough about its customers to remove this limit from cameras sold in the rest of the world.

    The Magic Lantern “fix” will restart the camera every 30 minutes, but you will still lose a second or two between clips. Not good for music performances, theatrical performances or critical parts of speeches or lectures.

    Bottom line – this is an inherent limitation of your camera – and part of the reason I sold my T2i and switched to Panasonic.

    Good luck!

    Hi Adam – your BMPCC has a micro 4/3 mount (sometimes called micro four thirds or MFT). Only micro 4/3 lenses or lenses adapted to micro 4/3 mount will work with your camera.

    Canon EF lenses are a special case. Their apertures default to the wide open position unless powered electronically by a Canon compatible mount.

    If you get the Sigma 18-35 f1.8 for Canon, you will need an adapter with manual or electronic aperture control. Adapters with built in manual aperture control are relatively inexpensive. Electronic adapters, especially Metabones speed booster/focal reducers, can cost almost as much as your lens.

    Here is a list of adapters that will work with your BMPCC and the Sigma 18-35mm f1.8 for Canon EF (prices approximate as of this post):

    Manual aperture control:

  • DSLRKIT Canon EF to micro 4/3 adapter with aperture control – $31
  • Electronic aperture control:

  • $399 Metabones Canon EF to micro 4/3 adapter – (back ordered)
  • $598 Redrock Micro Livelens MFT Active Mount for EF Lenses
  • $599 Metabones EF to MFT Speed Booster, 0.71x Magnification, +1 stop brightness
  • $659 Metabones EF to BMPCC Speed Booster, 0.58x Magnification, +1.67 stops brightness
  • If I were you, I would get the Nikon mount version of this lens and an inexpensive $21 Nikon G to micro 4/3 adapter or, if budget permits, a $489 Nikon to micro 4/3 Speed Booster with 0.71x magnification and 1 stop of brightness increase.

    That would be a lot less trouble and expense.

    Either way, this is a great lens for the BMPCC.

    Here’s what people are doing with the Sigma 18-35 on the Pocket Cinema Camera:
