Minolta can no longer rescue you!
For a moment the NEX excited me (especially after seeing the images Donald has posted here). However, I just read Sony's E lens announcement...18-200mm with a price tag of $800???. Did I read it right? We all know that Sony's lenses have always been expensive but at least on the Alpha models one can use the old Minolta Maxxum lenses and save some serious $$$. Well, that's no longer an option. So, watch your pocket if you want AF lenses for your NEX toy!

You cann't compare this lens with others - except Lumix 14-140 - similar price!

These are lenses for VIDEO cameras, even Canon/Nikon cannot build (focus following, noiseless, etc).

Sony 18-200 is primar a lens for E-mont VIDEO camera, not for NEX5 !
But you can buy a NEX5/18-200 kit for ~ 1000 (in Europe, incl. 20% VAT)

I've seen reports that AF worked with SAM and SSM lenses with prototype lens adapters and preproduction NEX cameras. But, apparently they still had some issues to work out and didn't include that feature in the production NEX firmware. I suspect we'll see it back in later though.

Screw Drive AF lenses may be a different story (as that would require an adapter with an AF motor) and may be more difficult to implement. But, I wouldn't rule out that possibility either with a newer adapter design later, as the answer given about AF in an interview didn't distinquish between AF lens types. See this interview where an answer implied that the design intention is to have AF via an adapter:

"Mr Katsumoto: Autofocus should be working with the adapter..."

Apparently, on the box, there's a sticker that reads "For MF (Manual Focus) mode". Also, in the instructions, it says it doesn't work with teleconverters.

The Sony adapter can stop down the aperture with A Mount lenses.

That's even on the page you posted a link to, in more than one place. ;-)

It's mentioned once above the main features here:

"Additionally, this adapter has Auto Exposure support with aperture mechanism and includes a detachable tripod attachment."

It's mentioned again in the AE section:

"Auto Exposure support with aperture mechanism"

You're right. My apologies. I read an earlier description of the LA-EA1 on Sony's website that said A-Mount lenses only worked at their maximum apertures. That description is gone and been replaced with the one that appears in the link I provided above.

I'll edit my earlier post so it doesn't show up in searches.

I thought the NEX uses E mount lenses...

shoturtle Aug 18, 2010 10:39 PM

yup the nex uses e-mounts.

But they were trying to come up with a way to us A mount lenses with an adapter. So currently there is only 3 lenses, and one of them is 800 dollars that will work on the nex.

Less comfortable, but my NEX5 works with all my 20 lenses :-) ... making fantastic pictures

even with 18-200

when I mean work right with A-mounts, I meant AF and aperture control. Currently if you mount an A-mount onto the nex. You just do not have those option. And they have not come out with the electronic adapter for the A-mounts in the states.
