● In the history of Minolta (now Sony) A-mount, there are two types: **"5 contacts" and "8 contacts."**
● 5 contacts (old standard): Common in early autofocus (AF) lenses and some third-party lenses. Performs basic communication such as AF drive and aperture control.
● 2. Compatibility
A-mount has high compatibility, and it works fine even with a combination of "8 contacts on the camera side and 5 contacts on the lens side."
• Although the camera side (αSweet) has 8 contacts, when a 5-contact lens is attached, it is designed to operate in the conventional communication mode without using the additional three functions (such as ADI metering).
● Accessories: 2 caps
