I understand that you don't understand. That's fair. But, like I said in the other thread, I'm sure you can *imagine*.
I mean, some people spend $5000 to gain 1/2 stop (F1.2 -> F1.0 = Noctilux). Some people spend another $5000 to gain another tiny fraction of a stop (F1.0 Noctilux -> F0.95 Noctilux).
Compared to them, what's $400-600? |
Well, I'll try to imagine.
Good luck with the speedbooster, I can see it's not for me, doesn't mean it's not going to be very useful to others. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

None of my lenses is compatible with EOS. Except a native Canon EF 50/1.8. Using EOS compatible lenses on a full frame camera hasnt been a problem for the last five years. Or when did the 5D appear? |

Perhaps have we reached the sweet spot of the topic (test thread).
1/We know, from the example, that the SB works (almost) perfectly with EF mount lenses.
If you have FF, AF, EF lenses, there are obviously other solutions for photographers.
But, why not : Your gain is a smaller body, and 1 IL.
The bonus is that you can try the SB with other FF SLR lenses.
(Rawhead is there, if I'm correct)
If you're a vidéo man, things are different. The SB was probably designed essentially for vidéo users.
(It's why the first testers are famous in the vidéo world.)
2/We know, from the example, that the SB doesn't work very well with stacked adapters.
Does the result worth the purchase ?
Are you ready to follow the Conurus's principle ?

If a FF NEX is coming out, does it still worth the pain ?
Whatever, the answer is yours.
I've given mine regarding the S B Metabones EF mount.
So, I must add this :
If a Nex FF isn't coming out, if the S B is sold in Europe, (if the tests are good - but I have no doubt about that), I'd probably buy the S B in Nikon F mount, as I've a long line of Nikkors (with 1 hole )
Still cheaper than any Nikon D FF, new or used.

Well, as we've seen, they've made sure all the Canon EF lenses work with it, but stacking an adapter and putting on leses from other mounts some times leads to mounting issues, so there's that.
Metabones also talks about the inevitable introduction of minute amounts of tilt with stacked adapters, which apparently is quite evident with wide angle lenses, so there's mechanical causes for the "degradation" of the IQ that they have no control over.
Like you say, the FD version might ameliorate a lot of issue #1, at which point I might switch over to that (and sell this EF version, as I have very little use for AF). _________________ Sony α7R, Pentax 67II, Kiev-60, Hasselblad 203FE, 903SWC, Graflex Norita 66, Mamiya M645 1000s, Burke & James 8x10, Graflex Pacemaker Speed Graphic (4x5 and 3x4), Century Graphic (2x3), R.B.

Exactly my thinking. An FD Speedboster would be tempting. For EF, I´d rather get a used 5D. |

We might get a bit carried away by what the Speed Booster cannot do. First and above all it is not all adapters for all purposes.
However if you have a special need then it makes mores sense. My special need was that I have a good kit of Canon EF lenses already. I also have a good if aging kit of Canon dslr bodies to go with them.
I would be first to agree that there is life in the old dslr body yet I also agree that dslr bodies can do things that mirrorless cameras still struggle with. But the gap is narrowing.
To upgrade my Canon dslr bodies is to replace like with like - there are just so many older dslr bodies you can have hanging around for backup, maybe they could be sold but then you do not have them to save changing lenses, but at some stage they are no longer useful as "extra bodies" (think 10D?) nor by this stage are they worth trying to re-sell. So do I keep my other bodies until they get "like-10D"? or do I churn them over on eBay for the latest and greatest 5DII, churn 5DIII ....? no doubt there is additional advantage there but a 5D still works well enough. If there will be 5DIV and 5DV then do I simply keep going and churning until one day they start looking very much like a mirrorless with a mirror? On Canon simply stops making dslr bodies and leaves your last purchase in the lurch?
EF lenses are not transferrable, at least they were not transferrable until Metabones made them thus. The EF bit meant that the electronic components had to work on any other non-Canon made body and Canon were not exactly going out of their way to help - for some reason I don't really know.
Therefore where I am at? I am not a Sony NEX man nor a M4/3 man and even the Metabones Smart Adapter was not enough to make me move. I had rather play with my Ricoh GXR and M mount module and have fun with them and reserve my Canon gear for special duties. However the release of the Speed Booster changed this. Now it was worthwhile to buy a NEX6 body and a Speed Booster to enable me to have another body to use my Canon EF lenses on. I am not about to compare the combination directly to a 5D (I still own and use one) but it made more sense and less money to buy the Speed Booster and a NEX6 than to buy a 5DIII and have redundant 5D (or spare body). It increases my effective kit without conflicting components.
So I saved on a 5DII and now on a 5DIII, as long as my original 5D still keeps working well I guess I can now hang out for a 5DVI at my latest calculation - that is if Canon dslr's ever make it to that model. My guess is that a professional level Canon mirrorless will be made before then. If so I will have to reconsider my options.

Convertible Double-Protar perhaps?
In a sense these do use the focal reducer concept. However, the convertible lenses of a century ago had no space limitations to contend with. They were also very slow lenses - normally about f/6.8 at maximum aperture. Also, this system was not "general purpose": you coudln't use the rear cell of a double-protar as a focal reducer for a Tessar or Planar, for example.
Of course the other Zeiss lens using a focal reducer concept was Glatzel's 50mm f/0.7. However, the rear reducing group in that lens was optimized to work with the front portion, and was not a general purpose adapter.
Or perhaps you had something else in mind? Do tell! _________________ Brian Caldwell |

There have been a lot of questions about a Speedbooster for Canon FD. Forgive my ignorance, but since there is one for Leica R and the registration distance for R lenses is greater than for FD lenses, aren't there adapters to from FD to R and then those FD lenses will be usable on the Speedbooster? |

Indeed you are right!
But there is an Alpa speedbooster in existence and Alpa Reflex has flange focal distance of 37.8mm - less than both FD and R and just about any other mount. So in principle one could use all these mounts, like FD with an FD to Alpa adapter and the Alpa speedbooster.
Or am I missing something again? |

yes, if I am not mistaken you are missing that there are not many x lens to Alpa mount adapters on the market and those that are are expensive
the Canon adapter offered till now still looks like the most versatile _________________ my photos on flickr: https://www.flickr.com/photos/kuuan/collections |

I guess the problem is that there is no Canon FD speedbooster as yet and though Alpa adapters are scarce (and I have not seen one for Canon FD lenses), they may be the way to go as the closest thing to a universal adapter? |

OK, so can you (or anyone else) confirm that it is possible to make a FD-Alpa adapter? or is there something about the mount that makes it impossible? |

There's also the potential problem (and perhaps Brian can chime in if he reads this) that the lens side of the Alpa adapter may not have an opening large enough to accomodate many of the faster lenses; if I remember correctly, Alpa never had a super fast lens like F1.2 or F1.4, did it? _________________ Sony α7R, Pentax 67II, Kiev-60, Hasselblad 203FE, 903SWC, Graflex Norita 66, Mamiya M645 1000s, Burke & James 8x10, Graflex Pacemaker Speed Graphic (4x5 and 3x4), Century Graphic (2x3), R.B.

This list at cameraquest is very helpful. It states historically what adapters are available for what lenses and what cameras.

The ideal "universal" mount has the shortest flange distance AND the widest mount throat. However as you can see from the list there are many useful combinations even if no mount is truly "universal". |

Well, the way I see it, ideal adapter would be in Leica M mount, since it has short register and there adapters to Leica M from most major SLR mounts. However M register might be too small for Speedbooster optics. My next choice would be 4/3. From FF SLRs, FD is the best choice since there are inexpensive m42 and Nikon F adapters to FD. _________________ Many lenses and some film bodies for sale here: http://forum.mflenses.com/canon-fd-minolta-md-c-mounts-m42-pentax-and-more-t50465.html
