I don’t know much about these things. Do they damage IQ much?
No one knows, because they are new. Time will tell.
Even the people who built it and people who tested it don’t know?
Speed Booster- the real stuff- has been tested and there is a lengthy white paper available. The rest are just trying to cash in on that with no real data.
Sharpness and vignetting will rise, CA maybe too.
As with the Speed Booster, the bokeh looks terrible when you shoot things with a narrow DOF. Other than that, there’s been plenty of image examples at the pie board posted ( http://piebbs.pconline.com.cn/topic-22378.html ), I think the image quality will be just as good as the Speed Booster.
One question with this Lens Turbo :
Is there any aperture ring especially for newer Nikon lenses ? How do you set the aperture? From the picture shown above, seems we won’t be able to adjust this.
The 1st version Lens turbo is for Nikon Ai-s.
Nikon G version will available soon (may be coming half year)
Hi mxcamera, thanks for the reply.
Looking forward for the next version then…
Where can we preorder the FD -> NEX Adapter?
Don’t mind, I already preordered now 😉
+1
MXcamera, will BE available. stop using available as a verb or the euro fascists will make fun of you again.
Hi there.
will there be any possibility to have a stable tripod mount on any of these?
Looks like the Mitakon Reducer doesn’t have much backfocus clearance (from SLR mount) and will have problems with many lenses
WTF? The lens elements are located where the mirror would be on an slr. If you have a ‘backfocus’ issue then the lens won’t fit on an slr either.
Approximately. But front lens in Mitakon reducer sits a few mm more front compared to SLR mirror.
Metabones reducer has the same issue, some lenses won’t fit and some need to modified
(read “List of manual focus lenses which REQUIRE MODIFICATION to be used on Speed Booster™” on their site). This Mitakon reducer will have it too (to lesser degree at the edges where various levers are located; and to greater degree on the optical axis).
Thanks for explaining that one. If it is a common problem for both then it really shouldn’t come into play when deciding which one to buy.
They should provide soft plastic mockup of their reducer so users could check if their lens/adaptor fits (Mitakon, are you reading this?)
Thanks. I looked this up, and for the Metabones EF/NEX Speed Booster it’s only non-EF lenses adapted to EF that are on their list (Leica R, Olympus OM, etc).
Hopefully that’s the same with these Lens Turbos – i.e. that only non FD lenses, or mirror lock up lenses, have issues on their FD/NEX.
What about the MD when will it be available?
What’s most important to me is this information from ebay-link : nex- Sony A /Minolta adapter coming soon!
I can soon attach my Alpha-mount zeiss-lenses to nex7!
You can do so already by using the Sony LA-EA adapters (these are not converters).
Exactly. They aren’t converters.
I want to have that 1 stop advantage that you wont get with any previous adapters. I’ll prefer effective 145mm f1.3 strongly over 200mm f1.8, which I would have with current adapters and my zeiss lens.
Will there be a Minolta MC/MD Version in the Future?
I’m curious about the material used for the body of the adapter. The adapter to camera mount seems to be part of this body where the lens to adapter mount is something altogether different. How will this wear in the long run. I am interested in this or the speed booster for my old Contax Zeiss glass. The speed booster claims a brass mount on both ends for durability and looks like it could be replaced if it wore out. Granted, the Mitikon is half the price but it concerns me that the mount will wear over time. Anyone have any thoughts on this?
When it wears off, the NEX-9 will be on the market. 🙂
Have any of your other lens mounts worn off ever?
None of my lens mounts have worn off. Eventually lens mounts will show signs of wear though. If the metal is soft, such as aluminum it will wear faster and eventually become loose and not fit snug. This in turn will affect focus and sharpness.
I tend to change lenses often because I prefer primes to zooms and I stopped buying cheap lenses because they don’t fit well after heavy use. My 30 year old zeiss glass shows wear but still fit perfectly. There is something to be said for craftsmanship and quality materials. As the old saying goes ‘try as you might, you can’t polish a turd”
Bugger, no sign of Minolta MD or Konica AR yet?
I also would like to see MD-mount converter.
Very tempted to try one of the nikon ones at this price but will have to wait until next month….
Hmm, do we trust a manufacturer who says their product will be available for Sony/Minolta Aplha? Or is this a mount I am unaware of?
LOL! We are bit pessimistic about the future, aren’t se? 🙂

Should have been “aren’t we”, of course.
Andrea, please! Can’t we have the Comment edit function back?

That is the new hybrid mount! 😀
+1. Only it isn’t a hybrid mount, it’s an adapter (no way you can get rid of the glass when you want to mount an E lens…). But I agree that’s the way to go for Sony. Forget about NEX FF, make an NEX top notch model which ships with this adapter (A mount), the way to go.
the ebay link doesn’t work !
It seems that a lot of people have legacy glass in popular and not so popular mounts. Here’s an idea. Why couldn’t they make and adapter with interchangeable receiver mounts? Almost like the reverse version of the old Tamron adaptal mount. Then they could sell 1 ‘speed booster/lens turbo’ and then sell various receiver mounts to fit almost anything.
+1. I have had the very same thought. It would be perfect for us, the consumers, but I can understand that the producers hesitate. However if this thing gets as popular as it ought to, then the competition would become intense and someone would surely offer interchangable mounts as a very compelling selling point. I won’t wait for that to happen though, as soon as the M42 version is out I will get it (unless I read bad reviews for the “Lens Turbo”).
The logical thing is for SONY (or Ricoh, Fuji, Samsung) to introduce a NEX with a fullframe sensor in place of the crop.
Then we can use inexpensive straight-through mechanical and AF adapters and without the expensive optics.
Sorry, what is the result of these mount to a APS-C lenses and not a full frame lenses? Get a black frame/border around the photo?
It will be like using a APS-C lens on a FF camera – dark/black border.
Depends how badly the lens vignettes on FF I suppose. For example the 35mm and 50mm SAM DT lenses (APS-C), should actually work pretty well… Once there is a fricken Alpha mount version available that is (which seems insane given these are made almost exclusively for NEX at this point in time).
I would love to see a Minolta MD version of this adapter if it’s possible.
Wish there were Nikon F to Minolta MD. I can then buy the MD adapter and be set!
Does this type of focal reducer exist?
Sony Alpha FF lens to Sony Alpha APS-C camera.
No, because restriction to keep back focal distance is very strict and it will cause such reducer to be very complex (see https://docs.google.com/viewer?url=www.google.com/patents/US5499069.pdf)
I noticed the contax g auto focus adapter is also now available to order again from these guys.
What will the focal length multiplier for this be? For Speed Booster it’s 1.03 I believe. A 40mm lens will be 41.2. This multiplies more, right?
Oh, it’s 1.09 for Speed Booster, which makes 40mm 43.6. This Lens Turbo thing will multiply even more and it will be something like 45mm? 40mm and 45mm is a noticeable difference for sure. I’m not sure I would call the result “full frame” as they do.
With a speedbooster a FF 40mm will be a 42.6mm on your NEX, while with the Lens Turbo it would be 43.6mm.
With the speedbooster the magnification is of 1.065 while with the Lens Turbo it is 1.089 and naked APS-C = 1.5.
So it’s not exactly like FF, but it’s much closer to FF than APS-C.
Thanks!
I can’t wait to get either a speedbooster or a lensturbo for my FD lenses !
It will turn my 28 F2.0 into a 20 F1.4 O___O and my 50 F1.4 into a 35 F1.0 can’t wait ! Can’t wait !
They shipped my Canon FD lens turbo adapter this morning. It was supposed to be available on May 27. But i guess some items were in stock now. I will post pictures in dpreviews NEX forum when i get it.
