Before the Metabones SpeedBooster, Kodak Had Their Own Design

Back in 1994, Kodak had a focal length reducer just like the SpeedBooster that made Metabones famous.

Back in the 1990s, digital photography was still just gaining a foothold and engineers were trying to figure out a number of problems and issues. It was done in a similar way to how the Metabones SpeedBooster gave cameras the ability to use lenses for larger format sensors while providing more light and field of view. Except for Kodak, it was to solve a significantly bigger problem around significantly smaller sensors. Before most cameras used CMOS sensors, they used CCD sensors–and really small ones at that. The sensors in those cameras would be laughable today for the professional photographer, and one of the big problems that needed to be solved was using available lenses.

A godsend to APS-C camera owners, [amazon_textlink asin=’B011GEMHU4′ text=’speedboosters’ template=’ProductLink’ store=’thephobl-20′ marketplace=’US’ link_id=’18ec7447-ad14-11e7-975c-d711eaf01f61′] allow photographers using adapted full frame lenses to regain some of the image lost in the crop factor as well as increase the light gathered by the sensor. Every lens is different and not every speedbooster will work great with every lens. However, there is a way you may be able to adjust this to achieve better performance with your speedbooster.

Fotodiox Announces its Budget Line of Excell +1 Speedboosters

Fotodiox Excell +1 Canon FD to MFT Product Image 2

Until now Metabones has been pretty much the only major name spoken of in the Speedbooster world but now Fotodiox is out with its own budget priced competitor named the Excell +1. Fotodiox’s new lens adapters will let shooter mount Nikon G or Canon FD glass onto a Micro Four Thirds camera.

Just like a Speedbooster, the Excell +1 is fitted with a corrective optical glass element that shortens the focal length while offering users a full stop of more light. The Excell +1 adapters also feature aperture rings letting users change the f-stop manually.

When mounting a 50mm lens onto a Micro Four Thirds camera, instead of being a 100mm lens the Excell +1 would effectively turn the lens into a 70mm instead of a 100mm field of view. Alternatively users could also mount the adapter and lens to Blackmagic’s Pocket Cinema Camera to get a lens with a full frame equivalent of 103mm rather than the usual 144mm. Fotodiox plans to release more Excell +1 adapters for more camera bodies in the future including the Sony E-mount, Samsung NX, Fujifilm X, and Pentax K mount systems.

The camera accessory maker is launching its Excell +1 at a special $139.99 introductory rate, a slight discount from the full $159.99 retail price. But compared to the equivalent $400 adapter from Metabones, Fotodiox’s units seem like a complete bargain. Those that order before July 22nd will also get a free Light Cannon Creative Adapter, which also lets users mount lenses to their Micro Four Thirds camera except with the added effect of a soft focus lens, thrown into the deal too.

We’ll have to get in an Excell +1 for testing before we can definitely say it has the same quality as Metabones adapters. Until then though check past the break for more images and a video.

The First Metabones SpeedBooster Knock Off Has Been Spotted in Real Life


Oh man, things are about to get heated. Metabones has been making waves with their SpeedBooster for mirrorless cameras. But Sony Alpha Rumors, has already spotted the new Mitakon knock off. According to the site, Mitakon’s parent company will avoid a patent lawsuit because the Mitakon has a reduction ration of 0.726 (Speed Booster is 0.71). It’s a manual adapter only while some Speed Booster adapters also support full electronic AF and Aperture control. The Lens Turbo price is set at US$239.

As it is though, Metabones has put a delay on their Micro Four Thirds products, and Jared Abrams already tweeted about quality issues. We’re wondering what will come next as this story just becomes more interesting.

Jared Abrams Offers Warning to Metabones SpeedBooster Users Via Twitter

Jared Abrams on Twitter

Last night on Twitter, Cinematographer Jared Abrams offered a warning to Metabones SpeedBooster adapter uses. Features Editor Abram Goglanian reached out to him asking what happened and apparently the adapter shredded the electronic contacts on a lens. The victim this time was a Carl Zeiss 35mm f1.4 lens–which goes for just under $2,000. From a producer’s point of view, that’s just another expense that you hope you budgeted for.

The adapter is extremely popular due to its widening abilities and the extra stop of aperture. It may make some people think twice about purchasing the unit if this doesn’t blow over well. But we also then wonder how many people are considering their new competitor Mitakon.

Metabones has already stated that their SpeedBooster for Micro Four Thirds has been delayed; let’s just hope that no more problems arise.
