T-mount to Sony A adapter compatibility

Mounting a T-mount (T2) lens on a Sony A / Minolta A body — the feasibility verdict, AF / IS / aperture-control / infinity-focus outcome, image-circle relationship, official and reputable third-party adapter SKUs, and the caveats worth knowing before you buy.

Flange-distance gap the adapter fills: 10.50 mm (55 mm − 44.5 mm). That gap is what a mechanical adapter has to fill to hold the lens at its design distance from the sensor.

Flange-distance schematic. Two rails share a sensor plane on the right. The Sony A body register measures 44.5 millimetres; the T-mount lens needs 55 millimetres. The orange region between their left edges is the 10.50 millimetre gap an adapter spans.Sensor planeSony A body · 44.5 mmT-mount lens · 55 mm+10.50 mm adapter
Both distances right-aligned to the sensor. The 10.50 mm gap between the Sony A body register and the T-mount lens (orange) is exactly what a mechanical adapter fills to hold the lens at its design distance.

Caveats

  • Mechanical adapter only — no electronic communication between T-mount (T2) lens and Sony A / Minolta A body.

Common questions

Will T-mount (T2) lenses autofocus on a Sony A / Minolta A body through an adapter?
Autofocus is not applicable to this pairing — the T-mount mount predates electronic AF, or the bodies in this family do not implement AF for adapted lenses.
Does in-lens image stabilization (IS / VR / OS) still work through a T-mount → Sony A adapter?
Stabilisation is not applicable — T-mount lenses in this family do not ship with in-lens stabilisation, or the adapter pair predates the IS protocol entirely.
What's the most-recommended T-mount → Sony A adapter?
No SKU in our curated catalogue covers T-mount → Sony A yet. Adapter examples photographers commonly use include the generic mechanical adapter ring (multiple vendors). Pair compatibility is mostly mechanical, so any well-built adapter at the correct flange distance should work — pick on build quality and tripod-foot integration.
