Focal length equivalents & field of view#

Multiply any focal length by 1.53 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 5.52 µm pixels, diffraction starts to soften pixel-level detail around f/8.2. For maximum sharpness keep landscapes between f/4.5 and f/8; 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 Leica X1 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 × 1.53.

Frequently asked questions#

What is the crop factor of the Leica X1?

The Leica X1 has a crop factor of 1.53× relative to 35 mm full frame (diagonal 28.3 mm vs 43.3 mm).

What size is the Leica X1 sensor?

23.6 × 15.7 mm (APS-C), an area of 371 mm² — 43% of full frame.

Is the Leica X1 full frame?

No — its sensor is APS-C, which is 2.3× smaller in area than full frame.

How many megapixels does the Leica X1 have?

12 megapixels (4,272 × 2,586 pixels), enough for a 14 × 9 inch print at 300 DPI.

How long can I expose the night sky with the Leica X1?

With a 13 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 20 s.
