Purpose-built teleconverter

The Panasonic DMW-STC20 is a 2x teleconverter designed exclusively for the Lumix S PRO 70-200mm F4 O.I.S. lens. It doubles the focal length of that lens to extend the reach for distant subjects while retaining autofocus performance.

Suited for wildlife and sports shooters

Photographers needing greater reach from their existing 70-200mm F4 O.I.S. will benefit from the extended range and maintained high-speed, high-precision AF. Users without this specific lens, or those requiring wider apertures or different mount systems, should look at other solutions.

2x magnification factor

The converter multiplies the native focal length by two, turning the 70-200mm zoom into a 400mm maximum telephoto option. This single specification determines whether the accessory matches the focal-length requirements of the intended shooting scenario.

Questions about this item

Will the DMW-STC20 teleconverter need any periodic maintenance or part replacement?

The DMW-STC20 has no user-serviceable parts; keep the contacts clean and store it in its case when not mounted on the LUMIX S PRO 70-200mm F4 O.I.S.

What is the first limitation I will hit when using the 2x converter on the 70-200mm lens all day?

The effective maximum aperture drops two stops, so autofocus speed and low-light capability become the limiting factors before heat or power.

Does the DMW-STC20 add noticeable heat, noise or power draw during continuous shooting?

The teleconverter is a passive optical accessory with no electronics of its own, so it adds no heat, noise or power consumption.
