A source just told me that Metabones is working on a special GH4 Speed Booster adapter that will create a perfect DX/Super35 lens view. There are no other specs and release info yet.
Reminder: Metabones just announced the new Olympus OM to Micro Four Thirds Speed Booster adapter. As you know there are a huge amount of OM lenses we can use!

Each “news” on this site is only an excuse to spread more and more sponsored links vaguely related to the news itself (ebay, amazon, etc…).
Sure admin wants to generate income, but I’m affraid 43rumors.com will soon be ranked as a “link farm” or “spam” site… :'(
Not very annoying, although lists of random lens links is a bit too much.
Causes clutter..
Do you know how to spell EXIT?

no you made me aware it, i did not know before..
auto-focus ,please
Good point !
only Metabones adapter EF to Sony NEX Mount are providing auto-focus,
I don’t know why they can’t do the same for MFT ?
An adapter made especially for Super35 cine lenses won’t have autofocus.
The adapter isn’t made especially for S35mm lenses, but it’s probably too difficult for m43 readers to understand..
ya me no comprende
This is great news, thank you for posting admin. I hope they hurry, it will be needed quite soon.
Wow my gh4 will get better , great .
If this is a dedicated 0.69x speedbooster with PL mount, then I welcome it. If it’s just a regular speedbooster with a variety of flavours of legacy mounts, then I don’t get what it offers over and above the current 0.71x speedbooster.
How is this dedicated to the GH4?
+1
Isn’t the current 0.71x speedbooster a perfect super35 when shooting 4k (2.2x crop)? Could this be fore perfect super35 with regular 2x crop?
Aha!…now I think you’re onto something here. The 0.71x on the 1080p 2x crop would work out perfect S35. However, the 2.2/2.3x crop of the 4k would require the same focal reduction as the BMCC specific SpeedBooster….so again, if the BMCC and GH4 4K share the same crop, why the need for a specific unit? I assume the flange to sensor distance is the same, so the slightly protruding parts shouldn’t be an issue.
Maybe we’ll just have to wait and see 😀
The current 0.71x speedbooster gives you a 1.42x crop factor down from 2x. The one rumored in this article would give you a true full frame field of view (ie, 0.5x speedbooster).
That isn’t what the article says… “GH4 Speed Booster adapter that will create a perfect DX/Super35 lens view”
yawn…where is my E-P5 firmware update????
While the S35 speedbooster sounds interesting, the constantly refreshing the site to check if the E-P5 update has surfaced.
Sounds great…but I’d rather that they invest more effort on the EF to μ43 adapter that they’ve said they’d do…
Would a BMPC Speedbooster with the increased magnification work with a Panasonic body with silent/electronic shutter since the shutter would not be activated?
In Short Yes.
“A word of warning though is that the Blackmagic one sits closer into the body than the standard one. This WILL interfere with the mechanical shutter…just. To avoid this, set the camera to electronic shutter only. This means the mechanical shutter won’t descend and you will be fine.”

So, in practice what is the difference from the current Metabones adapter to this one?
Wider view??? By how much?
Some of us here need subtitles on these news!
The current MFT Speedbooster reduces your crop factor by 0.71x. So on a GH4 or GH3 that would equate to a 1.42x crop factor instead of 2x. The Speedbooster rumored in this article would give you a true full frame field of view. The current Speedbooster gives you a 1.06x crop factor on MFT cameras with 1.5x crop factors.
But that is in no way what the article says… “GH4 Speed Booster adapter that will create a perfect DX/Super35 lens view”
Maybe they’re referring to the 4K resolution. The GH4 uses a cropped portion of the M4/3 total sensor area (roughly 500 less orizontal pixels) when recording 4K to avoid line skipping and pixel binning. As far as I understand this adapter will provide an increased focal reduction from the “original” 0.71X so to get an effective DX/Super35 aspect from the cropped area. That can be good news because lenses designed for 24X36mm film/sensors will be able to cover the cropped area as well as the “full” MFT sensor. On the other hand I guess that lenses designed for DX will cover the cropped area but not the “full” MFT sensor (?)
It hits and scratches the metal plate in front of the GH4’s sensor if you use the BMCC version, along with that if you accidentally take a photo while using that speedbooster, it will get your shutter stuck and most likely break it… Not worth $500 IMO to get something that could potentially break your camera, and cause vignetting at 1080p. I much rather wait for metabones to creak a specific speedbooster solely for the GH4, or just end up getting the original MFT/Nikon version, even if I am not getting the super 35mm look at 4K (which is why I’m leaning more to waiting for a specific model)
create* (not creak)
Anyone heard any news on this? I’m holding off on getting the generic nikon -> m43 speedbooster in the hope metabones are going to release a GH4 dedicated one.
