    Hi,

    Right now I am using vintage lenses like:

    - Nikon Nikkor AI-s 20mm 2.8
    - Nikon Nikkor AI-s 28mm 2.0
    - Carl Zeiss Jena Flektogon 2,4 / 35mm
    - Carl zeiss Jena Pebntacon 1.8 / 50mm

    Using those lenses with BMMCC and 0.58x Metabone Speedbooster. Works great.

    I ordered the Pocket 4K Camera and I am not sure with Speedbooster to buy.
    Three options:

    1. Canon EF Lens to Micro Four Thirds T Speed Booster ULTRA 0.71x
    2. Canon EF Lens to Micro Four Thirds T Speed Booster XL 0.64x
    3. Canon EF Lens to BMCC T Speed Booster 0.64x


    I was wondering which 0.64x speedbooster fits the "Pocket 4k" better. I could get the "BMCC T Speed Booster 0.64x" version for 300 Bucks second hand
    but I am afraid that it will not work. I also donīt understand why Metabone did not update their website and give us more informations about what Adapter works good with the Pocket 4k. When metabone released a EF to MFT Speedbooster they also designed a special one for the old Pocket or the BMCC. Will the design a "special Pocket 4k" speedbooster, too?

    I visited the Metabone site and found this option, too:
    Canon EF Lens to BMPCC T Speed Booster 0.58x (BMMCC and BMMSC4K compatible)
    https://www.metabones.com/products/d...SPEF-BMPCC-BT1

    WTF? This is the old 0.58x Speedbooster I got on my BMMCC and it is good to know that it will fit
    onto the Pocket 4K, too. But a 0.58x Speedbooster is above "FF - Fill Frame", right?
    I thought 0.71x is for APS-C Lenes and 0.64x for FullFrame Lenses?!

    And I donīt get it why they updated the 0.58x Website (fits on the Pocket 4k) but no information about the 0.71x and 0.64x version?!
    hmmmmm

    Not quite, while you can use the original Pocket Cinema Camera SB (0.58 MFT) on the new Pocket 4K, it will not cover the full sensor, but works well in window HD mode. The Canon EF Lens to BMPCC T Speed Booster 0.58x (BMMCC and BMMSC4K compatible) referees to the two BM Micro cameras, both the Cinema version you have, and the BMMSC4K, is the Micro Studio Camera 4K, not the new BMPCC4K (new Pocket 4K) Camera.

    I would opt for the Ultra (0.71) version, as this will match cameras shooting Cinema S35, like the Ursa Mini 4.6/Pro, and gives the lenses you are using a more normal cinema focal length field of view.
    Cheers

    Go with the BMCC 0.64x, it performs way better than the others with fast lenses.

    Thank you. I totaly forgot about the "Blackmagic Micro Cinema Camera Studio 4k" thing
    I just saw the 4k and thought metabone updated some infos about the "pocket 4k".
    I also think I am going with the Ultra 0.71x because I read the glass might be better. Less Chromatic aberration.
    Still wish Metabone would update their "compatible list". Would suck to spend 800,- Bucks and
    three weeks later they release some "new Pocket 4k designed speedbooster".

    Any thoughts about the
    "Canon EF Lens to BMCC T Speed Booster 0.64x" vs the
    "Canon EF Lens to Micro Four Thirds T Speed Booster XL 0.64x"?

    The BMCC Speedbooster is my recommendation as well. As it is cheap to get on ebay and works well, I shot with it and the BMPCC4K.

    2. Canon EF Lens to Micro Four Thirds T Speed Booster XL 0.64x does not work for me though, metabones have not responded to my email either.
