A-mount Adapter for NEX which gives it Phase Detection AF

[kei1309]

Different people looking and asking for different things. look.. if the LA-EA2 can now AF on all Sony lenses. Then.. people will start saying.. ooh.. but no IS.. so how. Are they going to make a LA-EA3 with mirror, motor and OSS? Its never going to end. Technology is improving and it takes time. The point here is Compromise and decide on which suit you best. You cant ask for everything (unless you're Tony Stark?). And btw..NEX are design to be small and light.

in OSS, there will be moving elements to compensate for the shake. in SS Inside, the sensor shifts. they can't fit the OSS into the lens mount adaptor... that means to stabilize the image, the WHOLE LENS would need to be moved. the other way to compensate would be to use electronic IS. which would mean a larger sensor area to shift the readout.

i'm guessing the LA-EA2 can only work with the new bodies because of software? that would mean they didn't make it backward compatible with the older generation of NEX

OSS would be in de lens, not adaptor (just like SEL18200). But I know its not logical for them to include OSS in A mount lens cos in de first place A mount body already have SSI (though sensor shift considered inferior to lens shift). So back to my original gripe/wish list: pls come out with a 16-105 OSS e mount.

Would be a shame if they deprive older NEX users of de new adaptor. Having said dat, I would very likely be changing to one of de new NEXes when they re released

 

[jennzhen]

Yes dats possible too. But I was replying to de earlier post/rumour dat de new adaptor would "only work for NEX 5N/7" and wat dat could mean. I felt dat it could NOT mean dat it can't be mounted on old NEXes (since they re all using e mount) hence de other possibility is dat de new adaptor would only function fully with de new NEXes cos de new NEXes have de body screw drive. If de screw drive was on de adaptor then it should work on de old NEXes as well.

My guess is the screw drive will be on adaptor, but the old NEX will not have capability to operate this screw-drive properly. Operating screw-drive must be different from SAM/SSM, otherwise LA-EA1 adaptor could do this already and Sony does not have to release LA-EA2.

Likely you can mount LA-EA2 to old NEX, since the e-mount likely wouldn't change. But it may not work properly.

Yes screw drive would have to be on adaptor as the lens is connected to the adaptor and not directly to the body. All the body would need to operate the screw drive (via the adaptor) is an eletrical connection with the adaptor - which is already available. So i tink at most old NEXes would only need to have a firmware upgrade to learn how to "talk" to the new adaptor in order to operate the translucent mirror and the screw drive as well.

I doubt there will be a screw drive on the adapter.

If you've noticed, pretty much all the new lenses have a built-in focus driver of some sort, like the SAM in alpha lenses.

Anyway, this opens up a whole new playing field with the NEX. Let's say I've got a NEX cam, if I'm going on a hiking/trekking trip and want it to be lighter, I just stick to whatever the NEX's got. After that, I'd like to go for a proper photo shoot, be it a wedding or some nature park, I can slip on the EA2 and start using the A lenses.

So really, the way I see it, the EA2 is not for the average consumer. It's for the more 'serious' photographer who wants flexibility, to be ablet o switch between convenience and performance.

With a NEX base, you still can step up to the Alpha level, and back again.
With an Alpha base...you're stuck.

yea. for those who want a back-up cam but don't wanna drag a heavy second body around.

De lens with have SAM are mainly de higher zooms (70-200/300/400), de more expensive lens (cz 16-35/24-70) and some of de prime lens. But somehow they omitted it from de day to day walkabout lens like 16-105, 24-105, 16-80 & 18-70/200/250 which is where my problem is. Having said de above, lack of OSS in A mount lens will be a bigger problem for NEX users than this internal motor issue.

I totally agree de EA2 will not be for everyone...and will probably cost quite a bit.

Why do you always spell "the" as "de" but can get all other words right???? :dunno:

It's de - oops, the - most common shortcut I use. Most of the other words dun have a ready shortcut. Anyway, interesting observation. Bothers u dat much?

Just an observation. And I guess because it's only that one word it really sticks out LOL :bsmilie:

I also use "u" (you), "dun" (don't) and "dat" (that) quite a lot but maybe somehow in my posts these other words are not used so often

 

[sje4182]

Checked several news sites abt LA EA2 but there is no mention of any screw drive involved. Guess NEX users are - well, screwed

nice way to put it :bsmilie:

From Sonyalpharumors.com, this new adaptor seems to have built in AF motor.

http://www.sonyalpharumors.com/sr5-more-new-rumor-tidbits/

- The new LA-EA2 adapter has a built-in AF-motor (it can focus with all Minolta/Sony lenses!)

 

[TWmilkteaTW]

About whether the LA-EA2 can fit onto the 1st generation of NEx-es.. this would be the question..
If can..then im pretty much looking forward to this adapter. Small and fast SLT. Small body with a bloody big head.

Best news I ve heard all year. And its SR5 so pretty much a sure thing. All I tink will cost not less than SGD$600...

if you buy the NEX-7, i believe it would make sense to buy this to make use of the legacy lenses

 

[TWmilkteaTW]

actually im expecting not anything above 500 SGD.. because if you were to buy a NEX..and that adapter.. it would probably cost more SLT already..A55 example. Infact..a NEX itself is already very close to the cost of a A55 SLT. But if it works.. its a good addition for NEX users..definitely.
Still waiting for more news : )

Sony doesn't compare it dat way when deciding on price. Anyway I read somewhere dat de "la-ea2 would cost around $400 as compared to de la-ea1 which was $150". Dun know which country they referring to but it appears wherever it is de ea2 is more than 2.5x de ea1. Since ea1 is selling for $300 here (RRP) so I m tinking de ea2 should be at least $600-$800. Hope I m wrong.
