Since it is not applicable to FastHybrid AF, the focus rate of AF85/1.4 is not high even with 99II.
Still, there are only a limited number of reviews, but the 7RIV+LA-EA5 seems to be slow but rarely out of focus. And the 7RIV also has EyeAF.
It's a pity that the 7RIV is extremely expensive, but the difference is not small.

Interesting. Looks ok.

However, these are with the zeiss 50mm. As yet I have not seen any videos using a screw drive lens, or rather someone showing a screw drive lens focussing. (Granted, I may have missed one). I think that is what many of us want to see.

Does anyone know if the la-ea5 will give screw drive af with the a7c? I assume not as it's heavily based in the a7iii.

But it also includes some of the later AF magic, so maybe? Iím still still waiting for Sony to update the compatibility chart.

Hmm in the video therein https://youtu.be/_8_sbr4UpF8


(around 1:50 or so) it seems the stopped down lag might still be there... 😓 hoping I am wrong 🙏

I'm sorry I have tired you. My opinion is very simple and easy to figure out. I don't believe conspiracy theories, only in Sony taking sound business decisions. Looking at the data I have it took Sony a couple of years to develope a LA-EA5 and it was ready to announce and sell now. I don't believe they had it fully ready a few years ago and just left it on the shelf until today. I have no idea when they started and how long they took since that all depends on how many resources they threw at it during the time they also developed several new E-mount cameras and lenses.

I think both of you need to understand how engineering companies design and market products. The engineering teams are tasked with developing products by marketing, according to an (often loose) spec, and they also do some R&D themselves which occasionally gets taken further to a working prototype.

At that point, a decision is made about whether to carry it forward to production - and the decision will consider lots of marketing issues (nothing gets manufactured and sold simply because it works) - and once this decision is made, the real work begins, with lots of more detailed design & testing, involving many months of work by a lot more people than did the prototype.

It's pretty rare for fully developed 'manufacturing-ready' products to be put back on the shelf (because it wastes so much money) though it does happen, but very common for working prototypes to be shelved for lack of market or for various other reasons (canibalising other products, cannot be sold profitably, no longer on the roadmap, etc).
I'd be surprised if Sony didn't have an LAEA-5 prototype in development somewhere several years ago, and either decided to wait to market it or made no decision at all previously. Then they decided they would, for all the reasons mentioned.
Miranda F & Sensorex, Sony A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras . . .

Fully agree Anthony, I worked for an engineering company (so I understand how they work) and this is exactly as we worked (and what I tried to explain to syber). They may have had the proof of principle or a prototype ready some time ago (nobody knows) but for sure they didn't have it all ready, tested, manufacturing geared up and then put on the shelf for a few years. That is just too inefficient R&D.
