T-Mount Adapter for Nikon DSLRs

The Opteka T-Mount (T2) adapter connects T-mount lenses or telescopes to a wide range of Nikon DSLR bodies. It is aimed at photographers who want to reuse existing manual-focus optics or attach their camera to a telescope for astrophotography.

Manual focus and stop-down metering only

The adapter breaks electronic communication between body and lens, so autofocus and automatic diaphragm control are lost. You must focus manually and set exposure manually or use aperture-priority stop-down metering; lenses without an aperture ring will remain stopped down to their smallest f-stop.

Infinity focus retained across listed models

The all-metal mount secures the lens firmly while allowing easy removal, and infinity focus is maintained on every compatible camera from the D3100 through the D5 and D810. It does not add optical elements, so image quality depends entirely on the attached T-mount lens or telescope.

Questions about this item

Will the all-metal T-mount adapter itself wear out or need replacing?

The adapter is all-metal with no moving parts or electronics, so it does not wear out and does not need periodic replacement.

What function is lost first when using a T-mount lens on a Nikon DSLR through this adapter?

Autofocus, automatic diaphragm control and any communication-dependent features stop working immediately; you must focus manually and set exposure manually or in stop-down aperture-priority mode.

Does the adapter generate heat or noise during all-day use on a telescope or long exposure session?

It is a passive mechanical ring with no electronics, motor or fan, so it produces no heat and no audible noise regardless of how long it stays mounted.
