Blackmagic Pocket Cinema Camera c-mount lens compatibility list

Recommended Posts

@Parky

I'm also quite happy with the Computar.

Its a shame that can't focus to infinity when wide open but in any other situation its quite a competent little lens.

Hopefully this can all translate well to the BMPC. If it does then I'm set with a 28mm, a 36mm and, with my Panny 20mm, a 57mm. 

I'm getting more excited about his little camera every day :)

Off-topic, but looks like I'll be sticking with the Kinor 16 format for now.  I've got a Wollensak CineRaptor 25mm f/1.9, Taylor Hobson 25mm f/1.9 and Bell & Howell Angenieux 75mm f/2.5 that will be sitting around collecting dust.  If anyone's interested, shoot me a PM.

Tried it now. It is more compatible to c-mount-to-M43rds adapters than the original Zeiss Jena c-mount, but only works with very thin c-mount adapters. It's really a question of a few millimeters (or even micrometers) whether or not you will get infinity focus. Most of my adapters failed except this one (which fortunately is very cheap): http://cgi.ebay.nl/ws/eBayISAPI.dll?ViewItem&item=230832760732#ht_3712wt_1165

Hi! I`m looking for a lens to attach on  BMPC, but, the choise is so hard... The bad thing is a crop factor, which is 2.88 as you talking here. 
I`m really hope, that the spec details is not final, and the crop would be 2.6. If so, we will get true 1920px cut from  2.5k image. And all the lens be good and quite similar as on cinema camera, i think. maybe a little soften.
 
But if  crop will be x3, i think i`ll buy  sharpest lens, so i can to get  much detailed image.
 
I`m affraid that if  crop 3 image will looks to much, blurry and detail less.
 
What do you think?

Sorry, but your posting is completely confused. You're mixing up crop factors and sensor resolution - the two things are completely unrelated!

I was curious about B3/ B4 lenses with 2x extenders. Ive seen people use them on the GH2/GH3 and they are mostly made for 2/3 sensors. they will work with the GH models, but if you effectively engage the 2x estender built on the lens it makes it double the coverage and double the aperture. So, a 16-100 f1.7 will be a 32-200 f3.4... so low light shooting might be an issue....I wonder how much of the BMPC sensor gets covered by that lens with the adapter without having to go into the 2x extender mode?

Another advantage of the B4 lenses from what Ive read, is that you have a parfocal lens that will maintain focus throughout the entire zoom range (and aperture does not decrease) and, with the right cable and battery pack you can use the power zoom on the lens (wild, isn't it?) Iris and focus is still manual, but I kinda like it that way.

And... the b4 lenses have macro and back focusing, so you can adjust your focusing to infinity even if you have some issues with the adapter...

The only advantage of the B3 adapter is that the B3 lenses will work on canon APS-C sensors as well. Im looking to buy a BMPC but I already have a T3i, I may alltogether sell it and switch to GH3, as I am looking to do more video work than photography, but since I have a bunch of lenses (FD and EF, EF-S lenses) Im kind of hessitant if I can figure out a way to get some good zoom lenses that I can actually interoperate with both cameras.

 

I found a couple of videos that show how they work on GH2 and GH3.
here is what Ive found so far...

Im about to pull the trigger and get new gear, so if anybody has any advice or info on these lenses or actually have one and have a picture they can share of it to see how it will scale on the sensor of the BMPC i'd greatly appreciate it.

Hi guys. I bought a Schneider Kreuznach Variogon 18-90mm f2 from a German eBay seller and just received this:

http://www.ebay.com/itm/Tamron-1-1-6-f-9-126mm-TV-Zoom-Lens-34785-/400395074585
 

It won't work on the Pocket, right? I'm guessing it's for 2/3 sensors but I can't find any info on the web. Also, what mount is that?

I intend to return it and get the right lens, though, but I wondered how far they missed from what I originally paid for...

EDIT: I checked, it's a B4 mount, and it's most probably for 2/3". I'd like to also use this lens on my GH2, and that's a no-no if I don't want to use EX-TELE (you have to enable it to use your Fujinon lenses, don't you andy lee?). The Variogon is a nice lens on the GH2 even though it vignettes a bit. I want it...

I think the only way you can use B3/B4 lenses on the gh2 or 3 without engaging ETC mode is if you get (and use) the ones that have the 2x extender in the back. Most of those B4 lenses have it built in (big black block looking thing in the rear with a switch, like on the video where the guy is doing a light test) If they dont have it? then your only other option is to go to ETC mode in the GH2 like he illustrates.

 

Advantage of using the 2x extender? it covers the sensor, duplicates your lens to a bigger range. Draw back, your aperture doubles as well, but, if you use the ETC mode which is nothing more than a digital zoom your lens image doubles, but your aperture doesnt (at least that my take on it, if anyone can confirm or cerrect me I'd greatly appreciate it)

 

Also, from what I've been reading, if you wanna be on the safe side, ger lenses that are designed for a 1 inch sensor (25mm sensors). some c mounts are 2/3, 1/2, and 1 inch sensor made. So just because its a C mount doesnt necessarily make it compatible with your sensor.

 

I think I am reposting something someone already posted here (ve been doing too much reading on the subject and I cant remember where I read it! HAHAHA) but here is a good source to know if the canons, fujinons and others have the right sensor format.

http://www.personal-view.com/talks/discussion/40/best-wide-lenses-/p4

 

Another thing to consider, in some cases, using it with wide open aperture will not look sharp, most of what I've read and seen shows that even at f1.7 some lenses look really hazy, but if you stop them down to f2 (some 2.8 or higher) they are as sharp a knife. I just ordered a Canon V16x16 (no 2x extender, scored that one for $22 because the electrical motor that adjusts the iris gears were broken, but since ithey wont work anyways I plan on gutting that part out) I plan on getting the adapter and taking it with me to an expo next weekend. Black Magic is going to have a booth there, so Im going to ask them to test it out see what happens...

That seems to be a B4 mount. I know tamron made some lenses for sony that did cover the 1 inch sensors like this one:
http://www.ebay.com/itm/200923103786?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

 

but i think the one you got is for a 2/3 censor as B4 is normally associated with either 2/3 or 1/2 inch sensors. you will have to use it on the GH models with the ETC mode, and it will be completely useless on a BMPC (unless you like vignetting).

I think this might be a good option as well. they make FD to M43 adapters now, and with the old FD's the iris is fully manual. I also have some old nikkor lenses (Non AIs) that might open another world of possiblities, as some of the older lesnes are not as expenssive as the newer ones....

 

Here is a video with some FD lenses on the GH2, and since these lenses were made for full frame, there shouldnt be any issues mounting on the BMPC.

well? I found a lens in a security camera store that will work in ETC mode , but won't work with the BMPC. its the RCA TV Lens 8mm f1.6. Its a one trick pony. paid $25 so it wasnt a terrible find. only has 1 single aperture adjustment but it will focus properly on a GH3. If anybody has a CCTV security or Spy camera shoppe near you? I highly recommend hitting those stores. The guy had a tokina tv zoom lens 12.5 -70mm f2.5 for $75, maybe i'll go back and get it.

 

Here is a pic with the BMPC sensor size:

Thanks for all the info guys! Really appreciate it.

 

I'm also searching for a decent wide-angle as I'm covered when it comes to the rest of the focal length, but it seems pretty hard to find a decent one due to the crop factor. The widest non-fisheye digital zoom lenses I found so far are the Olympus 9-18mm and the Panasonic 7-14mm (the latter costs more than the camera..).

 

In the CCTV world...

Computar used to make a 5.5mm f1.5. AFAIK it's the widest C-Mount produced (for 1" imagers). See here: http://www.ebay.com/itm/181163184870?ssPageName=STRK:MESOX:IT&_trksid=p3984.m1561.l2649#ht_363wt_1395

 

Computar used to make a 8mm f1.3. See here: http://www.ebay.com/itm/181133629085?ssPageName=STRK:MESOX:IT&_trksid=p3984.m1561.l2649#ht_487wt_1395

 

Cosmicar used to make a 6.5mm f1.8. See here: http://www.ebay.com/itm/181163179811?ssPageName=STRK:MESOX:IT&_trksid=p3984.m1561.l2649#ht_307wt_1395

 

 

All of these were made for 1" sensors. All are now out of production.

      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).

      Nippon Kogaku Japan Cine-NIKKOR 25mm F/1.8 wide angle lens. Close focus up to 2 feet / .6 meter.
      Nippon Kogaku Japan Cine-NIKKOR 10mm F/1.8 wide angle lens. Close focus up to 1 foot / .3 meter.

      Bought on eBay, used with C-Mount to Micro Four Thirds lens mount on Blackmagic Micro Cinema Camera. 
      Optically in excellent condition. Inside no specks of dust, haze, oil scratches that I can detect. Clicks work as expected. Focus is smooth.
      Cosmetically clean on outside. Very good for its age. 

      Close focus up to 2 feet / .6 meter. Very light weight, and tiny size. Smallest lens I've ever owned. Paired with BMMCC or BMPCC this makes a fantastic combination. BMMCC / BMPCC is super 16 sensor so I didn't need a speedbooster, and no vignette. I would expect to see vignetting on any sensor size larger than super 16.

      EXTRA
      Comes with a 40mm Switar C-mount lens, Metabones MFT to C-mount adapter.
      SELLING as a complete set. Asking $570 OBO.
