Alpha Lenses With Adapter AF Performance

I haven't tried myself, but there are some videos floating around on YouTube and flickr. So far, it looks like those who predicted terrible performance are correct, and I think I'm glad that I didn't buy any SAM lenses. I may sell my LA-EA1 adapter.
Indeed
I tried 70-400 G, it takes about a second to get focus. Acquisition is fairly quick, but the focus confirmation is slow. No fast action with this lens on NEX, but the lens is usable now, as compared to before. What is great is that the AF (just as clumsy as contrast AF is), works on video!
Cheers,

Hmmm, I wonder if it'll grab focus faster with faster aperture lenses ... just like any other AF camera? Are there any faster lenses with SAM?
Maybe ordering the AF adapter was a mistake. ??????
Just use the camera as intended.
Although I'd love to use my Leica M lenses on this pup ... the M 21/1.4 and 50/0.95 would be interesting on a tripod if it's easy to zoom in on the LCD for manual focusing ... is it?

manual focusing on the nex is a breeze, even more so with the new firmware.
Do you know who makes the best Leica M to NEX adapter? Maybe that would be a better choice.

They are the most expensive but with the tightest tolerances for infinity focus....
Voigtlander.
If I may ask ... who has those? Is there a specific model# or specific designation I should ask for?
Price is no object when mounting big buck M lenses on the camera.
-Marc
What is it in new firmware that made it more easy? I thought the original MF Assist hard key was already a breeze.

Sorry Marc for not including full details. I'm traveling and it is hard to put in some links. Steve Gandy at cameraquest carries Voigtlander adapters.If I may ask ... who has those? Is there a specific model# or specific designation I should ask for?

with the new firmware you even have more control of the camera, including the ISO in 1 touch.

Marc, I only use rangefinder lenses with the NEX, and I too find focusing a breeze. I second the Voigtlander adapter recommendation. I haven't found the tolerances to be any better than the much cheaper Metabones adapter, but the super low-profile lens release tab is worth the price of admission, IMO.
Thank you so much!
Cameras arrived ... A55 and NEX5 ... small ... tiny cameras.
Sony 50/1.4 looks like it was made for the A55. Have a Minolta 24-105 that will have to do for now. Surprised that the Minolta focused so fast. ISO 1600 looks pretty good. Have to read the manual a bit ... figured out most of it ... but still need to read some.
The NEX is really small, but would be perfect with some of the smaller M lenses.

I've got one of these little suckers on the way for NEX, and it is tiny. Only a bit longer than 4mm when collapsed!

sweet, how's the image quality on that?

Look forward to your images with that, Douglas.
Edit: The price is too steep for a triplet. I guess without the M mount and RF coupling, it could be cheaper by
about $400.

People seem to like it on the M9, so I think it should be fine on NEX. I've only heard from one user on NEX, and he said that the center is sharp but the corners aren't great wide open, but I'm ok with that. It should be fine in the corners stopped down.
Here's some good info about it: http://www.rangefinderforum.com/forums/showthread.php?t=94672

When in focus assist mode you can zoom tight in to focus and then can move the point of focus around.
With the new firmware, it will remember where you left it, so you can check composition and return back to where you were focussing quickly and maybe leave it off centre if you want to take a series of portraits for instance.
I'm not sure if I'm the only one who complained that it used to forget where you were, but this is a boon for me and helps a lot when manually focussing on anything other than the central spot.
