New Sony 400mm f/2.8 GM lens switches explained

Our reader Rzero explained them:

Using SAL300F28G2, SAL500F40G and SEL100400GM as reference, the switches should be for

1. AF/MF
2. DMF STD/Fulltime
3. Focus Limiter
4. Focus Hold
5. Prefocus Set Button
6. Optical Steady Shot ON/OFF
7. OSS Mode 1/Mode 2
8. BEEP ON/OFF button.

Or maybe that’s what it really does :)

New Sony 400mm f/2.8 FE GM lens prototype shown today has many unmarked switches. Here they are explained :) – #sonyimages #sonyalphasclub #sonyalpha #sonyphotography #sonyphotogallery #sonyalpharumors #sonyalphagear #SonyPhotoGallery #SonyAlphasClub #SonyMirrorles #sonyalphaphotos
