Player One M42F-M48M Adapter (0mm)

Product Overview

The Player One M42F-M48M Adapter is a machined aluminium adapter that converts an M42 × 0.75 female interface to an M48 × 0.75 male thread. Player One lists it as a 0 mm adapter — it steps between the two thread standards without adding optical length — with a 6.5 mm physical body. It carries M42 × 0.75 female threads on one end and M48 × 0.75 male threads on the other.

Who It's For

This is a good match if you need to take an M42 (T-thread) part up to the larger M48 thread standard in an imaging train without adding spacing.

Key Features & Design

• M42 female to M48 male: converts M42 × 0.75 to M48 × 0.75.
• 0 mm optical length: steps thread standards without adding optical spacing; 6.5 mm physical body.
• Aluminium 6061-T6: machined aluminium body, light and rigid.
• Mechanical only: no optical elements and no electronic connection.

Recommended Uses

• Thread conversion: move from an M42 interface up to M48 in a camera or filter train.
• Minimal-spacing joins: where M42-to-M48 is needed without adding backfocus.

Compatibility & Accessory Notes

One end is M42 × 0.75 female; the other is M48 × 0.75 male. It converts between those two standards only. Because it is listed as a 0 mm adapter, it is chosen where the larger thread is needed without spending backfocus. If you are working out your total spacing, send us your setup and we will confirm the fit.

Good to Know Before You Order

• Mechanical adapter only: it changes the thread interface — there are no optics and no electronic communication through it.
• M42 to M48 only: it does not adapt other thread standards.
• Zero added optical length: the physical body is 6.5 mm, but Player One rates it as a 0 mm adapter for optical spacing.

Frequently Asked Questions

Is it difficult to set up?

No — it threads directly between an M42 female part and an M48 male interface with no tools.

What threads does it have?

M42 × 0.75 female on one side and M48 × 0.75 male on the other.

Does it add backfocus?

Player One rates it as a 0 mm adapter for optical length; the physical body measures 6.5 mm.

Bottom Line

In short: a machined aluminium M42-to-M48 adapter that changes thread standard without adding optical length, for stepping an M42 train up to M48.
