Metabones delays shipment of ‘Speed Booster’ for Micro Four Thirds










Share:








Metabones has announced the schedule for the Micro Four Thirds version of its innovative ‘Speed Booster’ lens adapter has slipped to the second half of 2013. Like the existing version for mounting Canon EF lenses on Sony NEX cameras, the forthcoming version will allow the use of full-frame lenses, reducing the focal length by a factor of 0.71x and increases the maximum aperture by 1 stop. The Micro Four Thirds version will give a 1.4x overall ‘crop’ – giving a similar field of view to APS-C stills cameras and the Super35mm video format.

The Speed Booster is available in an increasing number of other lens/mount combinations. Its first incarnation was a Canon EF to Sony NEX apapter, which we tested by mounting a few Canon lenses on a Sony NEX-6.ย Click here to read some of our initial thoughts on the possibilities and challenges presented by such a unique product.

Notice on the Metabones website

‘We apologize but the m4/3 schedule is slipping. Manual focus lenses such as Nikon, Leica R, Contax C/Y, Contarex, ALPA and Rollei will be supported in the second half of 2013. Canon EF lens (but not EF-S) support is planned in the future, but we do not have an estimated date yet.(viaย 43rumors)

The ‘Speed Booster’ lens adapter allows users to mount SLR lenses on APS-C and Micro Four Thirds mirrorless cameras that reduces the focal length by a factor of 0.71x and increases the maximum aperture by 1 stop.

Still no word about Nikon(G) > Nex/Fuji speedbooster, as “promised” in January :/

it’s not a very good idea to use a lens on a format it was not designed for. but for 4/3″ users they don’t have other choices at the moment. 4/3″ makers have been refusing to make large aperture lenses because they want to cheat with small ones.


Pasadena Perspective

I don’t mean to disagree or be difficult, but in my experience using both, I don’t see a disadvantage to it in most cases. Granted, a design that uses glass has more complications than a transparent one (like the passive EF to M43 adapters with no aperture control, etc.)

Are you speaking more about image quality or control? On the image quality side, I use everything from compacts to phones, camcorders, mirrorless cameras and DSLRs and find no image quality disadvantage to using DSLR lenses on M43 systems – they just have an entirely different crop. ๐Ÿ™‚

I hope they can sell the technology to cameras manufacturer. so it can be built in


Jun2

Don’t think manufactures want to have that built in and help Canon sell more lenses.

Having seen these things in the astronomy world for 30 years, many of us were wondering when they’d release something like it for cameras. Now that it’s here, we see the expected shortcomings (added aberrations) and realize it will be mostly a “centre of field” device. But I’m wondering if it even makes sense getting one? You can buy f/1.4 lenses now from 24mm all the way to 85mm and that is pretty fast. Some of them are very sharp, even wide open. There are also lenses that are as fast as f/0.95 (Schneider CCTV lenses, and others, usable on m4/3rds). My guess is most people will find that going up one stop in ISO will be a better idea than using this compressor except in rare circumstances were every last drop of speed is needed. This kind of device would have been far more useful 5 years ago when cameras were much noisier at high ISO.

I’m not sure you can buy the lenses you’re talking about for m43. FF yes, but this news item is about m43. In particular, there are no wide lenses as fast as you are taking about.


paulrfarrington

There are 17 and 25mm f/0.95 primes available for the u4/3s system.


JTHAIN

Does it have to be a Full Frame lens? Wouldn’t APSC lenses work on a micro four thirds sensor? Or would there be vignetting? I’m thinking this might make for a great northern lights shooting lens. Wide and fast.


Sergey Borachev

I think this booster does more for NEX than for M43 as it does not provide any wider FOV. It can provide more lens speed, which would make fast FF lenses even faster and that sounds good for re-using legacy lenses which are cheap and fast. However given the ghosting or flare issues when using those lenses on M43 cameras, I also wonder how good the end result will be with such speed boosting. Lots of question marks here. Are there independent tests yet?


TO Photo

The FOV has to change based on the physics. The MFT crop will be reduced but not eliminated.


Gao Gao

They should make a 2x booster with 4x ND built in


Rob Sims

I’m waiting on the Nikon f-mount to Sony e-mount for this one… Hopefully it’ll be available before this year is out.

Saying that, I haven’t heard that many user feedback threads yet regarding the existing Canon one yet… How well has it generally been received?


rusticus

with fast lenses, such as the old Nikkor 50mm f1.2 or 0.95 Nokton is now already more cinema look feasible than necessary – who needs this adapter? I do not


bobbarber

rusticus, Even though it’s called SpeedBooster, I think it’s more about focal length… Your Nikkor 50mm 1.2 will have two focal lengths on m43, with and without adapter.


Zoeff

I’m secretly hoping that they’re working on turning it into a 0.5x reducer but I doubt that’s going to happen. ๐Ÿ™


bobbarber

That’s what they should have done. It’s theoretically possible…I think. ๐Ÿ™‚


Raffwal

IIRC, the designer commented on some forum or website that due to space constraits they could not go below x 0.7.
