As you can see speedboster made for this camera has contacts in the back of it 

So I have MfT black magic 2.5k and sigma 18-35 on the way with speedboster made for BMC now I just found out I can't control aperture on my sigma with dumb adapter. Since BM don't have those control contact point how is aperture controlled by camera?

Hi, I know this is old post, but wanted to ask if you get any signs of vignette or image degradation on the corners using a BMPCC speedbooster (0.58x) on a BMCC? I have a BMCC and I had an XL speedbooster (0.64x) but sold it. I'm looking into the BMPCC speedbooster, but I have those concerns. Thanks!

Hi there still debating which speedboster to get did you get any?

Hi guys can Pocket Cinema Camera OG -Metabones Speed Booster 0.58x Canon EF Lens to BMPCC OG work with black magic cinema camera 2.5k any issues you see here ? I was looking also at new BMC 2.5 speedboster specifically made for BM 2.5k  

Ibis be bmc 2.5k I have those batteries can anybody recommend power adapter that’s I can use with those batteries 

thanks

I would, if I knew I was going to stick with MFT for the next few years. 

As what is there that could compare with the Laowa 7.5mm f2?

I guess a Rokinon 10mm f2.8 that's speedboosted up would be the equivalent.

What about metaboones  speed booster with yashics ml 2.8 lenses 

Would EF - MFT mount Speed Booster XL 0.64x work on old BMC 2.5K camera ? Metabones says The Speed Booster XL 0.64x is similar to the Blackmagic-specific 0.64x BMCC Speed Booster (MB_SPEF-BMCC-BM1), but has been completely re-designed to meet the following requirements) also I can see in the chard circles that’s it will work what do you guys think I am thinking of using this new speed booster with adapter for my yashica lenses

I own both the SLR Magic 8mm F4 lens and also the Laowa 7.5mm F2 lens, and the Laowa is the superior lens by far in every way, except cost.

 Would you go with Laowa over speed booster ? 

I have few yashics ml lenses can I use my yashics glass on ef metabones with adapter ?

Looking at the product pages on Metabones' site, this note is interesting:

I don't know if the standard speed boosters can be powered by micro usb - I'd find that out before considering one if you have a BMCC 2.5k and want to use electronic EF lenses.

Hi I don’t need electronic option since my lenses are vintage 

Can any m43 speedboster fit on black magic cinema 2.5k or I have to look for specific one for my bmcc2.5 k

The Metabones micro43-EF Speedbooster product pages have info on certain types/models of manual focus lenses which are not compatible due to having rear protrusions which could damage the Speedbooster e.g.:

General m43-EF Speedboosters:

https://www.metabones.com/products/details/MB_SPEF-m43-BT3

https://www.metabones.com/products/details/MB_SPEF-M43-BT4

BM-only m43-EF Speedboosters:

https://www.metabones.com/products/details/MB_SPEF-m43-BT8

https://www.metabones.com/products/details/MB_SPEF-M43-BT9

(scroll down to the 'Manual Focus Lens Compatibility' section near the bottom of the page)

Yashica is not on the list.

  

I did some digging and I found this article using xl speedboster EF to m43 with adapter

Here’s a 2021 Update: You don’t have to do this for modern speedboosters like ULTRA and XL, mine fitted perfectly on the viltrox EF to MFT with cheap ebay CY adapter (Except I had to turn the glass of speedbooster to fix infinity focus) but that’s a seperate issue. 

On the Metabones some lenses might scratch the velvet side only slightly so maybe if you don’t want that you can trim the pins just slightly but not the whole way using a professional or at home with metal cutting plier. 

I think author uses old gen speedboosters since it’s 2016 but I also read this post while my lens is arriving by post and I panicked a lot and this post made me panic even more having to do this to a rare lens.

Can I use adapter in front of speedboster since I can’t find a specific one for my camera. I have old BMCC 2.5k m43 but can’t find specific one for my yashica mount can I just purchase EF to M43 camera mount then use EF to yashica adapter is this recommended or big NO

Thanks

If you went EF mount route, I would've recommended the Magic Booster by LucAdapter.

In my opinion its a cleaner application...

I think he is only applying an OLPF filter here not the actual focal reducer, but same way to apply it:

 

Won’t work for me my is M43

You can adapt various mounts to EF, such as Pentax, Nikon F, M42 and Yashica Contax. The latter youn cannot adapt to Nikon as the flange distance is larger. Nikon F has one of the largest if not the largest flange distance of any 135 film cameras. You can adapt Nikon lenses to EF but not the other way around. See flange distance on wikipedia as it lists the different mounts and flange distances. The you can check if adapters for different combinations of mounts are available.

Thank you for the info so basically metabons speedboster EF I can use my yashica lenses with adapter ?

Also found this one N/F Nikon to BMCC for 100 dollars but who knows if it will work with adapter

The Bmcc booster is specifically suited to the sensor. Printed letters on the shell are indeed bmcc. There is another 0.64 booster without this specific bmcc lettering for the Lumix GH line besides a similar 0.71 model. Contax to EF adapter and you are set. Had been using ef to contax. Just test out some of these very affordable adapters. How have you been using your Yashica ML lenses, with an ef to mft adapter?

I see I believe I just bought non specific MFT to CY yashica speed buster like one in the image for black magic pocket then I just used it in my BMCC 2.5k when I bough. I found some images  of my sled buster I don’t see any BMCC markings

You mentioned I can buy  Canon EF Lens to BMCC Speed Booster and just sue adapter between my yashica and speedboster ?  
 

Thanks for you help

It's the 0.64 version, specifically built for the Bmcc. It has it printed on top of the plastic shell. Check out the official website:

https://www.metabones.com/products/details/mb_spef-bmcc-bm1

Ef version. Contax to ef mount can be connected with an adapter. I imagine you already know that.

But haven't you been handling speedboosters a lot before?

Have you settled for Zeiss or Yashica ML?

Hi yes I did have this setup 7 years ago sold it all but now I am buying my old gear back. Owned pocked cinema camera with speed booster but it did not have any markings of  BMCC then I remember I just kept it and used it in BMCC2.5k 

you mentioned I can used ef speed booster made for BMCC with yashica adapter ?  I ever know that would that introduce any issues ?

thansk for your isn 

Hi guys I bought my self black magic cinema camera 2.5k MFT I also have set of yashica ml prime lenses, I am looking to purchase metabones speed buster. On metabones website they have new speed booster  Contax Yashica CY Lens to Micro Four Thirds Speed Booster ULTRA x0.71 CINE I am not sure if this one will work with my full frame lenses and BMCC 2.5k  as I was researching it say it might vignette with full frame lenses. Also 6 years back I owned this camera with metabones speed buster and same lenses but can’t remember which metabones it was I only found a pic of it below I think it might be 0.64x version what should I do here any help would be appreciated 

Hi guys looking to build set of lenses i i am focusing mostly on Carl Zeiss vintage lenses there are so many out there with same name what are the most looked after Carl Zeiss Planar T* ? And do they cover 6k or full frame?

Thanks 

Anybody know the difference between Mamiya Sekor c and cs thanks

They will cover the frame but why choose such cheap lenses for such a good sensor?

because money is the problem i guess cameras are mowing to full frame in the near future just looking for good set to buy

What set of primes would you guys recommend under 500 a lens

Are Yashica ml lenses full frame as in full frame that can be used on full frame video cameras like kinemini 6k LF thanks

Guys any idea if my metabone ultra 0.71 will work with this new pocket  since sensor is bigger
