Panasonic DMC-TZ101

The Panasonic DMC-TZ101 is a compact with a 1" (one-inch) sensor measuring 12.6 × 9.4 mm. Its crop factor is 2.75×, so a 50 mm lens frames like 137 mm on full frame. Every number below is calculated for this exact sensor.

The Panasonic DMC-TZ101 sensor (highlighted) drawn to scale against common formats. Its area is 14% of a full-frame sensor, which collects about 2.9 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 2.75 to get the full-frame field of view. For fixed-lens cameras use the real focal length printed on the lens (e.g. “6.1–18.3 mm”), not the 35 mm equivalent.

Equivalent aperture#

Exposure is identical at the same f-number on any format; equivalence only describes depth of field and total light.

Night-sky exposure limits#

Longest exposure before stars trail. The NPF rule accounts for pixel pitch and is stricter than the classic 500 rule — use it for pin-sharp stars on high-resolution sensors. (NPF needs a known resolution and is omitted here.)

Handheld shutter speed guide#

The reciprocal rule uses the equivalent focal length. High-resolution sensors may need one stop faster than this for pixel-sharp results.

Lens#

The Panasonic DMC-TZ101 has a built-in, non-interchangeable lens. Use the real focal length of that lens with the tables above; its full-frame equivalent is that number × 2.75.

Frequently asked questions#

What is the crop factor of the Panasonic DMC-TZ101?

The Panasonic DMC-TZ101 has a crop factor of 2.75× relative to 35 mm full frame (diagonal 15.7 mm vs 43.3 mm).

What size is the Panasonic DMC-TZ101 sensor?

12.6 × 9.4 mm (1" (one-inch)), an area of 119 mm² — 14% of full frame.

Is the Panasonic DMC-TZ101 full frame?

No — its sensor is 1" (one-inch), which is 7.3× smaller in area than full frame.

How long can I expose the night sky with the Panasonic DMC-TZ101?

With a 7 mm lens (19 mm equivalent) the 500 rule gives 26 s.
