Anonymous: “This wasnt reported at the time but there was an interview at dc home a few months ago which i think would be an interesting discussion. In the interview the interviewer asked about the A77II AF module in the LA-EA6. The Sony engineer says the size of the module is a problem for an adapter. It would be an interesting discussion around would the readers accept a larger bump in the LA-EA4 to get better AF?

Translated:
–The mount adapter equipped with translucent mirror technology isn’t made denial, but I think I’m incapable to use 15 point AF sensor of LA-EA4 by full-sized α as expected. I think thing asking I don’t have is understood sufficiently, but there should be LA-EA6 α 77 II treated to 79 AF sensors (temporary)…,….

Hosokawa: The size of the AF module also becomes big to achieve a wide AF area.

It’s a problem whether it’s put in the size which can permit that as a mount adapter and after all whether the usual type phase contrast AF system by translucent mirror technology is a good one or, is a system using image face phase contrast AF good? The place where I’d like to reduce what kind of merit there is to a customer and think as technological directionality.

Japanese Text:
――トランスルーセントミラー・テクノロジーを搭載したマウントアダプターを否定はしませんが、やはりLA-EA4の15点AFセンサーは、フルサイズのαで使うには力不足だと思います。ないものねだりは十分承知していますが、α77 IIの79点AFセンサーを奢ったLA-EA6（仮）があればいいな、と思うのですが……。

細川：広いAFエリアを実現するには、AFモジュールのサイズも大きくなります。

それをマウントアダプターとして許容できる大きさに収められるかどうかが問題ですし、そもそもトランスルーセントミラー・テクノロジーによる従来型位相差AF方式が良いのか、それとも像面位相差AFなどを使う方式が良いのか? 技術の方向性としてお客さまにどういうメリットがあるのかを整理して考えていきたいところです。“
