Hey guys.
I just found out about this adapter.
It is supposed to be an AF adapter for MF lenses. I have no idea how that would work.
http://techartpro.com/product/techart-pro-leica-m-sony-e-autofocus-adapter/
Interesting how you can buy additional add-ons for different mounts, so after initially investment, $70 per adapter isn't terrible if they are very well made and have AF.
Seems like maybe a good way to get high quality, inclusive of all mounts with AF to boot? $370+ is not cheap though...
Is anyone familiar with this? Any thoughts on pros or cons? Would anyone consider this?
Is this a big deal? |

It is discussed in this thread already:
http://forum.mflenses.com/techart-leica-m-to-sony-e-af-adapter-in-development-new-t73879.html
It is tempting.
But it only has ~0,5cm of z-shift focusing (because of LM short flange distance) and it focuses with a noisy stepping motor - this are its weak points for me, so far.
I'm considering buying it but I'll wait for some trustworthy independent reviews first. |

+1, game spoiler for me... if i want AF i'll take the 5D with L lenses.

"AF is for loosers", sorry, just couldn't resist as I'm a rather addicted mf'ler
and being able to quickly focus about anything after years of practice. BUT
for moving objects, cats, people etc. it certainly has its use for sure!!
The short focusing distance, "Z-axis" as Dan calls it, is a major drawback
as many lenses I have, have a massive focusing distamce, especially for
my close-up / macro use, so won't help there anyway. And I doubt it could
handle some 2000++ grams of lens, too

Thanks guys for the input, and sorry to rehash something that you guys apparently knew!
I feel the same way, there's a reason I use vintage lenses. Not just the difference in optical quality, but the manual focusing capabilities.
I think it might have a good certain use for specific purposes, such as doing "sports" photography with vintage glass for whatever reason, but I also don't see need for it myself.
I wonder if it'll somehow increase the demand for vintage glass, or if most true vintage glass users don't care for AF like the gang here. |

On lenses with longer travel, it is probably best to think of it as a focus "fine tune", as you will probably need to do a rough manual focus first.
I wouldn't spend a fortune on it, but it would be interesting to try. I doubt it is going to be fast enough for action, which is where I most appreciate good AF |

It's not really a "game changer", as Pentax has been selling for years an adapter providing autofocus capability for Pentax K or M42 manual focus lenses (the SMC Pentax-F 1.7x AF Adapter). I seem to remember Nikon also offered a similar device at some point.
Cheers!

Interesting piece of technology but I won't be buying one. Like most of you I'm not interested in AF - I'll stick with MF.
I can see this as a negative though. If it gains traction eventually people will figure out that legacy glass is more affordable than the new stuff. And as more people start buying it the prices will only go up. Guess I better start stocking up now.

The game change is focus confirm, whether by chip adaptor or nonmoronic camera firmware.
I may be totally mistaken but all "af" buys you would be the ability to shoot while jumping and rolling. Well probably it is too slow for that. When you have to move the whole lens or camera things will not work as well as real AF.
You may stretch on your toes and get five foot closer to some gizmo you cannot get to. Sometimes an advantage.
When I heard about a similar system (moving the plate/lens) I thought it was a pretty ingenious, if somewhat obvious, idea, though. |

Come on! It would spoil whole point of having manual focus lenses  .
I agree that AF has it's use on some occasions, but I still prefer MF with proper metal lens. I was shooting 2,5 year old in the park (daughter of friend) and she was blazingly fast (as the kids just are) and AF just wasn't fast enough. What's more I cannot frame photo everyway I want because I had to stick to focus points of AF. Well after 5-10 minutes of strugling I got out my manual 135mm/2.5 and it was a lot easier to nail the focus even at f/2.5-f/4.
I know, that more expensive cameras and more expensive lenses do AF a lot lot better than my Canon 600d with Tamron SP 17-50/2.8, but still it's not completely rubbish combo.
On the other hand I must admit, that having such mf->af adapter will give me opportunity to be actually in focus on the photo somebody else is taking with my camera . From some time now I do f/8-f/11 and pre focus usually on hyperfocal to ensure I'll be 'sharp' when somebody else is taking the photo.

Of course, it is only compatible with A7ii, A7Rii and A6300 and only for Leica M lenses...so not for me but I am confident there will be more of these plus in a couple of years, most probably, some MD rokkor ones and compatible with new cameras.

Your first point is a good one.
I think the adoption of an M mount should open up pretty much any manual SLR lens as an option, with a relatively cheap M mount adaptor? |

Yes, but the M-mounts short flange distance limits the amount of Z-shift so you'll have to roughtly prefocus many SLR lenses. An SLR mount version would allow for more Z-shift but there is no obvious SLR mount that would allow for adapters to all the common mounts:
40.50mm - Konica F & AR
42.00mm - Canon FL & FD
43.50mm - Minolta SR & Fujica X
44.00mm - Canon EF & Praktika B
44.50mm - Sony/Minolta A & Rollei/Voigtländer QBM
45.46mm - Pentax K, M42
45.50mm - Contax C/Y & Mamiya Z
46.00mm - Olymous OM
46.50mm - Nikon F
47.00mm - Leica R
A new mount with 35-38mm flange distance would be ideal but we might need to wait quite a while for cheep 3rd party adapters...

This for me is the point of this adaptor, and that is exactly how I plan on using it when I get one. It's not to replace MF with AF, it's simply to enhance it, refine it and help get critical focus. You still have the manual focus workflow and sensibility, just a little helping hand at the end to hit focus just right.
