M42 Lens to Minolta AF/Sony DSLR AF-Confirm Adapter

Works for: Sony alpha a100, a200, a350, a700 (all current Sony DSLRs), and old Minoltaa5D, a7D DSLRs

Material: The adapter is made by copper with chrome coating which is better and stronger than made by aluminium.

Description:

- Basically it is an emulator of Minolta/Sony system AF lens, by attaching a 'smart' PCB chip on a conventional lens mount adapter.

- Whenever your subject gets in focus, the AF confirm indicator will light up for your notice.

- IS function work as well as Sony AF Lens.

How to use:

- Mount the adapter (with the lens);

- Turn on the camera (motor will starts and make a few seconds noise, to self-examine) aperture value now will show as f1.7 (pre-set value);

- Set the camera to whichever mode you want;

- Aim your lens to the subject;

- Whenever the subject is in focus, the AF confirm indicator in viewfinder will light up;

- In general, 'AF confirm' will work for aperture value down to f/5.6 ~ f/8 (depending on lighting conditions), if you need to go further, focus above f/8 then stop down).
