- AF confirm M42 to SONY adapter,fits M42 lenses to Sony alpha a100, a200, a350, a700 (all current Sony DSLRs), and old Minoltaa5D, a7D DSLRs.
Made of copper with chrome coating which is better and stronger than made by aluminium,with high quality.
M42-Sony non-flange adapter for pretax takumar lens and non aperture pin lens.
Allows focusing to infinity.
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).
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.
EXIF is fixed 50mm f1.7
