Panasonic Lumix DMC-FZ28

The Panasonic Lumix DMC-FZ28 is a bridge camera with a 1/2.3" sensor measuring 6.1 × 4.8 mm and 10.1 megapixels. Its crop factor is 5.60×, so a 50 mm lens frames like 280 mm on full frame. Every number below is calculated for this exact sensor.

Sensor size compared#

The Panasonic Lumix DMC-FZ28 sensor (highlighted) drawn to scale against common formats. Its area is 3% of a full-frame sensor, which collects about 4.9 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 5.60 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.

Diffraction & pixel pitch#

With 1.67 µm pixels, diffraction starts to soften pixel-level detail around f/2.5. For maximum sharpness keep landscapes between f/2.8 and f/2; stopping down further trades detail for depth of field.

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.

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 Lumix DMC-FZ28 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 × 5.60.

Frequently asked questions#

What is the crop factor of the Panasonic Lumix DMC-FZ28?

The Panasonic Lumix DMC-FZ28 has a crop factor of 5.60× relative to 35 mm full frame (diagonal 7.7 mm vs 43.3 mm).

What size is the Panasonic Lumix DMC-FZ28 sensor?

6.1 × 4.8 mm (1/2.3"), an area of 29 mm² — 3% of full frame.

Is the Panasonic Lumix DMC-FZ28 full frame?

No — its sensor is 1/2.3", which is 29.8× smaller in area than full frame.

How many megapixels does the Panasonic Lumix DMC-FZ28 have?

10.1 megapixels (3,648 × 2,736 pixels), enough for a 12 × 9 inch print at 300 DPI.

How long can I expose the night sky with the Panasonic Lumix DMC-FZ28?

With a 5 mm lens (28 mm equivalent) the 500 rule gives 18 s and the stricter NPF rule at f/2.8 gives 30 s.
