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.

DonalDuc Aug 19, 2010 5:01 AM

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

even with 18-200

shoturtle Aug 19, 2010 11:53 AM

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.

The only adapter that Sony has released so far supports Aperture Control using Minolta A Mount (a.k.a., Maxxum, Dynax, Alpha) lenses with the NEX models. They've never released one without aperture control, and the pre-release adapters even supported Autofocus with some lenses (although AF is not available with the production adapters wiith the current NEX firmware, Aperture Control is).

The production Sony adapter is in short supply in the U.S. But, if you do some digging around, some dealers have them now.

Here's one example:

More dealers should have them in stock soon.

shoturtle Aug 19, 2010 6:36 PM

But it does not work with all lenses. But you can get it still. So they are still trying to debug the system. But I expect that when they release a final product. It will work just like the ones for the m4/3 camera, with full functions.

JimC Aug 19, 2010 6:44 PM

Aperture control works with all Minolta A mount lenses and always has (wiith both pre-production and production adapters).

AF is the issue (you need to use manual focus with all A mount lenses for now).

shoturtle Aug 19, 2010 6:45 PM

To me it makes no sense to get an electronic adapter that does not off full feature. JMHO

JimC Aug 19, 2010 6:57 PM

So, that you can use lenses that don't have an aperture ring (no Minolta AF mount lenses have one). ;-)

AF would be nice to have. But, given a nice LCD with magnified live view for manual focus purposes, that would be a secondary consideration compared to Aperture Control for many users.

shoturtle Aug 19, 2010 6:59 PM

If you buy an AF lens, you should have that feature especially if you spend the money for an electronic adapter. It really should have full features.

JimC Aug 19, 2010 7:07 PM

The NEX models are not meant to be an upgrade for existinig A Mount users. That's one reason Sony went with a new lens mount.. But, the adapter does give A mount users a solution if they do want to use their existinig lenses with a smaller camera model wth video ability, only you'll be limited to manual focus for now.

If you want full functionality including Autofocus with A mount lenses, buy a Sony dSLR instead (and they've already announced they'll be releasiing new models with the ability to record video this year). ;-)

shoturtle Aug 19, 2010 7:14 PM

I have said to each their own. I am from the school of thought that if you buy and electronic adapter, you should have full features like what panny and oly did. But with the softness of the 2 kit lens, some of the A-mount lenses would be a better option. But buying a digital camera and mounting a AF lens on it and having MF only is not really something the vast majority of buyers want. Now most of the target market, the kit lenses will be a vast improvement from what they are uses too. So if you were serious into photography, and want some sharper images with the nex you are just limited to MF currently.

I really hope they can get all the AF issue resolved. That way sony owner that want a small compact body with sharper images can mount some of the good minolta and sony G,CZ lenses on it.
