This Could Be the Most Disappointing Lens Speed Booster

Recently, we looked closer at the Hasselblad’s XH 0.8 Converter.

Lens speed boosters give you more focal length range and extra light. They’ve been known to photographers for a while now. They’re also great tools for those who want more from their lenses. But unfortunately, they’re not all created equal. The Hasselblad XH 0.8 Converter is designed to give you a 645 format feel and look. And we discussed that in our recent episode of Pro Camera Reviews.

Canon Apparently Has a Focal Reducer for EF-M Mount in the Works

Canon is developing a Metabones-inspired focal reducer for the EOS M system that will convert a 50mm f1.4 lens to a 40mm f1.2–or at least that’s what a patent says!

Despite the EOS R full-frame mirrorless camera being the most popular of Canon’s recent releases, the company has maintained its commitment to the EOS M APS-C mirrorless camera line. Looks like they’re busy cooking up something to prove this as well; reports have surfaced about a Canon patent for a Metabones-inspired speed booster for the EF-M mount.

Here Comes Another Speed Booster Clone, the Baveyes 0.7x Focal Reducer

Kipon IB/E Optics Baveyes 0.7x Focal Length Reducer It seem that Metabones started a trend with their Speed Booster focal reducers that allow you to use 35mm full frame lenses with their original field-of-view and one extra stop of speed on your APS-C camera. After the Chinese company Mitakon with its Lens Turbo, now the German/Chinese co-op between Kipon and IB/E Optics–the people responsible for the über-fast 40mm f0.85 mirrorless lens we recently reported on–have come up with another take on the same idea, which they named the ‘Baveyes.’ Wow. First ‘Handevision,’ now ‘Baveyes.’ What’s next?

Anyway, back to the topic. The Baveyes adapter, which will adapt Leica R, Canon EF and Nikon F-mount lenses to Sony NEX or Fuji X cameras, sports an 0.7x focal reducer optic which will turn any 35mm full frame lens into the equivalent needed on APS-C to yield the same fiel-of-view as on a full frame camera. With the added benefit of exactly one stop extra light gathering capability. In that regard, it is very similar to the Metabones Speed Booster and the Mitakon Lens Turbo, only that each company uses its own specific focal reduction ratio.

So what exactly does the device do? (For those not familiar with the general idea of a focal reducer.) When you put a Canon 50mm f1.4 lens on the Baveyes adapter, its focal length and relative aperture will both be reduced by a factor of 0.7x, so it will be turned into a 35mm f1 lens. On an APS-C sensor, a 35mm lens acts roughly the same in terms of fiel-of-view as a 50mm lens on a full frame camera. So you get the same (original) field of view, but a faster aperture which means faster shutter speeds at lower ISOs.

The adapters will be available from January 2014, which is next month, and will retail for around US-$300. That places them right inbetween the Lens Turbo and the Speed Booster.

Your Old Olympus OM Lenses Might Soon Work With the MetaBones Speed Booster


The admin of 43Rumors received a major tip that MetaBones might be releasing a Speed Booster for Olympus OM Lenses to Micro Four Thirds cameras. Users of the format have always loved using those lenses, but with the new addition of the Speed Booster, they’ll gain loads more capabilities such as a wider focal length and an extra f-stop of performance. At the moment, this is still a rumor, but the admin is usually pretty darn good on nailing what’s true and what’s not.

So let’s analyze this: a 35mm f1.4 lens will become a 24mm f1.0. But then you consider the 2x crop factor ratio that Micro Four Thirds cameras have. So that 24mm f1.0 approximately becomes a the equivalent 48mm f2. Still not too bad considering that it is still faster than the real rendering of most Micro Four Thirds lenses sans the offerings from Voigtlander. You’ll have to pry my 17.5mm f0.95 out of my cold, dead hands.

While the world is very much smitten with these items, Jared Abrams apparently had a perfectly good Zeiss lens destroyed by these units–so caution is always advised.

Speed Booster by Metabones Delayed for Micro Four Thirds

According to Four Thirds Rumors, the Speed Booster by Metabones is being delayed and will be out in the later half of 2013. The company announced the product would be available this month, but it looks like it will take longer. To refresh your memory, the speed booster takes a full frame lens, adapts it to a smaller format, and makes the focal length wider in addition to giving it an extra stop of aperture power (making it a faster lens.) With Mitakon apparently making the same thing, we’re wondering who will win the race.

Mitakon To Do Pretty Much What Metabones Did with the Speed Booster


According to Sony Alpha Rumors, there is a big new player in the speed booster world. As a refresher, Metabones did something that Zeiss did many years ago–they created an adapter that not only widens the focal length of a lens but as gives it an extra stop of light. Metabones recently created tons of stir in the photo world with it and they even announced that it will be coming to Micro Four Thirds soon (it is already available for Fuji X and Sony NEX). But the Chinese factories have probably received a copy and are now apparently copying it. A new company called Mitakon may allegedly make it more affordable.

This is going to be an interesting battle. The Chinese tend to really eat into sales when it comes to photography accessories, and this one will be worth the while to watch.

Metabones Says Their Speed Booster for MFT is Coming in April



Get ready to be happier than a red neck being fed bacon, Micro Four Thirds users (how’s that for a visual). The Metabones Speed Booster adapter that is supposed to make your lenses wider and deliver more light gathering abilities is coming to the Micro Four Thirds system soon. Price may be around $399 (still not final decision yet). So what does this mean?

– It will be easier for the users to get wide angles with a faster aperture

– The opening of a whole new line of focal lengths. If you already adapt something like Leica R glass to your camera, you’ll have more light gather abilities and wider focal lengths. So your 35mm lens will become a 24mm and then when put onto Micro Four Thirds will become a 48mm lens with lots of light gathering abilities and shallower depth of field. Huzzah!

Metabones Announces New Speed Booster: Conflicting Reports Over What It Actually Does

Metabones has announced something that has rocked the industry today; but there is conflicting information on what the adapter actually does. First off, it’s called the Speed Booster. So far it works for Fuji X series and Sony NEX series cameras. Hang tight Micro Four Thirds users, they promise that compatibility will come soon. Their product pages list the stats, which you’ll see after the jump. But something doesn’t add up here.
