I think a good solution is to replace the lens side chip and make the TC chip unreadable.
One day, I'll be wondering if this can be applied.
Thank you for the nice information.

It would be nice if SONY released the LA-EA4's Filmware that released the trivial restrictions, or the development environment.

FWIW: Kenko teleconverters work on all of the LA-EA adapters. The DGX models enable working AF with motorized lenses. Swapping the Kenko DGX electronics into the first-party teleconverter sounds like a possible solution to me.

The Monster modified LA-EA4r doesn't work with the Kenko teleconverters, but supposedly will work with the first-party ones.

It is possible to 'de-chip' a TC by lifting some of the pins and adding wire links. I did that to a 5-pin Kenko TC with a dead chip but haven't checked the pin connections that would be needed on an 8-pin.

It's a pity there don't seem to be any cheap E-mount TCs. A 1.4x would be useful to use E lenses on the A7 range without cropping.

Some may remember my love for 3x-1x macros. LA-EA4 does not recognize this lens. Even if you attach it to the camera, you will not be able to use the aperture because it will be "no lens".
AF is not possible with LA-EA3, but it recognizes it properly and can use the aperture.
I have high expectations for "LA-EA4r Monster Adapter".


The lens or LA-EA4 aren't a problem if you want to use this on lens on an E mount body .
Just fit a new chip from James Loa .
I replaced the electric contacts of a Minolta 2x tele-converter with one so I could mount a Minolta 300mm f/4 lens on it and still have AF and use it on E mount bodies .
The chip reports itself as a 600mm f/4 , so image stabilization works just fine .
( I swapped it over as a snapped the ribbon cable whilst cleaning the elements of the tele-converter )
See here where I made a post about it ; https://www.dpreview.com/forums/post/60010907

The fella asking in that thread had a lens whose chip was dead , so bought one for that reason .

It'll still work fine on an A mount body .
Just remember the chip needs to report another lens i.d so image stabilization needs to be switched off ( which it would do automatically with this lens anyway )
Also any micro focus adjustment might be thrown out if you had the chip programmed with an i.d of a lens you also have .

Please note these chips can't be used to replace the contacts on SSM lenses , as you remove any connections to the motor .

I think I can be persuaded to buy an LA-EA5. Or I could use my A99....

Didn't knew that there was that limitation with the LA-EA4. It's also far from perfect with SSM lenses that why I used the word in quotes.

Is the form of "Sony shop" unique to Japan? They deal only with SONY products, and supply information is directly transmitted from SONY. Formal may be overstated, but it is very accurate information.
And SONY is not the same operation all over the world. There are also models such as the DSLR-A850 and ILCE-3000 that were not sold in Japan because they were considered to have no demand. Since the A65 was hardly sold in Japan, the A68 is for overseas use only.
This time it will be gone because of "no parts", but it may be possible to distribute the inventory to countries where the transition to E-Mount is slow.
There is already only LA-EA4 on the accessories page of SONY Japan's online store.

I checked the big US sites, Adorama and Samy's still show the LA-EA3 as available. However, B&H defaults to the LA-EA4 and states there is no listing for the LA-EA3. THAT says discontinued to me!

I fail to see the link to where Sony made the formal announcement on the page you provided. The la-ea3 it's still available to purchase if you follow the links on the same page.

---
Edit: I see now they have the message "Production completed" for the LA-EA3
It's not exactly an announcement, we can speculate on the meaning of this but only time will tell. My guess is that for the number of current sales they should have enough in stock for the foreseeable future and there is always the LA-EA4 as an "alternative".

weren't you one of the non-believers that such a thing could be possible


The comment was really tongue in cheek but I don't think I was a "non-believer", only highly sceptical in the time that:
- Sony and some other sources said it couldn't be done
- There was no proof to the contrary

Now with the recent "monster adapter" stories it seems possible for some lenses and only the newer bodies, still I am eagerly waiting for some test results to see if all body AF options are available for all lenses.

Irrespective it it works or not, or if it's a DIY home job or a Sony branded product I don't think I will buy one but would very much like the fact it is available, not just to stop the complaining that there's no options for old A-mount lenses to use all the bells and whistles of the newer bodies , but also because it breathes new life into old A-mount glass for the people who think they can't properly use them today.

The A68 was not sold in Japan. It is an overseas model.
