Focal length equivalents & field of view#

Multiply any focal length by 1.33 to get the full-frame field of view. Angles are for a rectilinear lens focused at infinity.

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 6.86 µm pixels, diffraction starts to soften pixel-level detail around f/10.2. For maximum sharpness keep landscapes between f/5.6 and f/10; 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.

Frequently asked questions#

What is the crop factor of the Leica M8?

The Leica M8 has a crop factor of 1.33× relative to 35 mm full frame (diagonal 32.4 mm vs 43.3 mm).

What size is the Leica M8 sensor?

27.0 × 18.0 mm (APS-H), an area of 486 mm² — 56% of full frame.

Is the Leica M8 full frame?

No — its sensor is APS-H, which is 1.8× smaller in area than full frame.

How many megapixels does the Leica M8 have?

10.3 megapixels (3,936 × 2,630 pixels), enough for a 13 × 9 inch print at 300 DPI.

What lens mount does the Leica M8 use?

The Leica M8 uses the Leica M (flange distance 27.80 mm).

How long can I expose the night sky with the Leica M8?

With a 15 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 20 s.
