Is that why they gave a voucher for a free metabones adapter in Australia?

A rather obvious 'bait-and-switch' marketing ploy... and the extra premium that Aussi customers normally pay for their gear probably covered the cost of the adaptor anyway!

Maybe but it goes against what you are trying to claim

Not at all

I was saying that Sony is trying to make money on the A7 and A7r system through the FE lenses and so they are not interested in making third party lenses work well on these bodies

This is actually a reversal of the policy with the NEX product line. The NEX bodies were always releatively expensive and Sony were rather slow to bring lenses to market for that system so they encouraged legacy lens use for those products

NEX and A7/R are very different product ranges, but many NEX users still haven't realised that yet

It appeals to existing owners of those other systems and encourages them to buy the 'bargain-priced' A7 or A7r. Their existing lenses 'work' on the A7 via the adaptor, but not quite as well as an alternative E-mount lens would work. What do the owners do? Some will certainly replace their current lenses with E-mount ones!

Mabye they will, I for one won't

Good for you, but not representative

I'm currently in a rather similar situation... I recently bought an expensive long telephoto zoom in A-mount (70-400G) to use on my NEX-5R as there was nothing suitable in A-mount. The resulting IQ is good, but operationally the the E->A-mount adaptor is driving me crazy so I am now wondering about buying an SLT-A77 (or changing system, or just hoping for an E-mount alternative to be released in the nearish future)!

I currently own an A99 and A7r, I bought the A7r with the 35mm to be my small camera and also so that I can invest in one set of (a mount) lenses, I already owned the 70-400 g2, 24-70, 85 f1.4, 135 f1.8 and 50 f1.4 and a Zeiss Planar 50 f2 and Leica Elmar-C 90 f4 both in m mount. The A7r gives me great results with all of those lenses and the only thing that I lose with any of them in functionality vs using then with native bodies is the IBIS on the a mount lenses...

Have you used your A-mount lenses on your camera yet?

If you had you would have noticed that you do not have direct AF focus point selection witout having to dive into the menus (better A-mount bodies typically allow immediate access to this); nor focus peaking nor imgage magnifcation when in AF mode; nor the ability to customise the button on your longer lenses; nor DMF (this is an E-mount feature but which could be calculated for screw-AF A-mount lenses)

I also have an A900, and the 70-400G (v1) is a dream operationally when used on that camera (direct access to all the features I want), but a disappointment in terms of IQ ( http://www.dpreview.com/forums/post/52639783 ). However the reverse is true of the same lens mounted on a NEX-5R via LA-EA2

So I dint really know what you think is hair and switch or what your issues are with the LA-EA4 but I strongly disagree with your conclusion.

Please see the post just above in reply to 'harold1968' where I list my suggestions for improvments which should have been made to the LA-EA4 prior to release : http://www.dpreview.com/forums/post/52844912

Also with regards to the AF info you wish that Sony would release, Sony did that as a white paper a couple of years ago for the e mount, I am not aware of any other company doing that, normally third parties have to reverse engineer everything.

Yes, when they were still producing the NEX range (already mentioned this above as part of the NEX strategy). You will notice that they DID NOT release details of the revised AF protocols which were implemented around the time PDAF was introduced into E-mount cameras

DEO-TECH have already said their adaptor's AF problems come from Sony not releasing details of their newer AF protocols and are trying to reverse engineer them so that they can make improvments

And actually companies do licence their mount specs to third parties for a price (the difference with Sony was that it was free). The only company which 'reverse engineered' mounts rather than paying the licensing fees was Sigma which is why there are so many compatibility problems with older Sigma lenses on newer bodies

These are the reasons that your post made me laugh enough to respond.

I hope you laughed long and deep

Rather a rude way to respond to a reasonable argument, don't you think?

I got 'baited-and-switched' by the 'adaptor' idea, and I'm sure I'm not the only one...

For what reason? Handling? IBIS? You could have bought a Nikon or Canon equivalent lens (if there was one as good) and then looked at their SLR options instead of Sonys, I don't really understand why you feel aggrieved or how you feel Sony have wronged you personally.

Why put words into my mouth? This kind of emotive talk just causes flames and arguments

I don't feel 'wronged personally' otherwise I would have sold all my Sony stuff and jumped straight to a Canon 7D and EF100-400/4-5.6 (a pretty good lens, and tests of the Nikon AFS 80-400 suggest that lens is even better than the Sony equivalent though Nikon DSLRs do not appeal to me as I find them confusing to use)

I needed a long lens for my NEX-5R. None was available in E-mount so I bought an A-mount lens and an LA-EA2 adaptor thinking that would be a good option. It turned-out to be a 'working option', but also rather frustrating in use so I need to look at buying an appropriate A-mount body to get the most out of the lens (and my A900 is not suitable, surprisingly)

As I said, bait-and-switch...

And for what it's worth, I think that at current prices the A77 is an amazing camera if you do decide to go down that route.
