Product overview

This is an all-metal lens mount adapter built from hardened anodized aluminium with a matting varnish interior to reduce internal light reflections. It lets you attach Canon EOS EF and EF-S DSLR lenses to Sony E-mount mirrorless bodies, including the Alpha a7 series, a6000-series APS-C cameras, and older NEX models.

It is a manual adapter with no electronic contacts, so autofocus and in-camera aperture control are not supported. You set aperture on the lens (or it defaults to wide open) and focus by hand; infinity focus is supported. Canon STM-series lenses are noted as incompatible.

Reasons to consider

• You own Canon EF/EF-S glass and a Sony E-mount body and want an inexpensive way to combine them.
• You are comfortable shooting manual focus — common for video work, adapted vintage-style shooting, or tripod-based photography.
• ₹3,399 is a low entry cost compared with electronic smart adapters, which typically cost several times more.
• Fulfilled by Amazon with free delivery, so returns and delivery are straightforward.

Pros and cons

Pros

• All-metal anodized aluminium construction
• Anti-reflective matting inside the barrel
• Broad Sony E-mount compatibility list (a7 series, a6000 series, NEX, FS-series)
• Infinity focus retained
• In stock at a verified ₹3,399

Cons

• No autofocus or electronic aperture control
• Canon STM lenses explicitly do not work
• The advertised 80% off / ₹16,999 MRP is not shown on Amazon, so the true saving is unclear
• Aperture adjustments require removing the ring or shooting wide open, per the product notes

Buyer fit

Best for photographers and videographers who already shoot manual focus and want to reuse Canon EF/EF-S lenses on a Sony mirrorless body. Not a good fit if you rely on autofocus, shoot moving subjects, or own mostly STM lenses.

Final verdict

At ₹3,399 this is a sensibly priced, well-made manual adapter for Canon-to-Sony adaptation, and the price and stock are verified on Amazon. The headline 80% discount is an advertised figure the merchant page does not confirm, so buy it for what it is — a cheap, solid manual adapter — rather than for the claimed saving.
