Focal length equivalents & field of view#

Multiply any focal length by 1.00 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 4.59 µm pixels, diffraction starts to soften pixel-level detail around f/6.8. For maximum sharpness keep landscapes between f/3.8 and f/7; stopping down further trades detail for depth of field.

Maximum print sizes#

At 41 MP the Leica M10 Monochrom produces 7,842 × 5,228 pixel images. See the 40 megapixel guide or the print size calculator.

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 M10 Monochrom?

The Leica M10 Monochrom has a crop factor of 1.00× relative to 35 mm full frame (diagonal 43.3 mm vs 43.3 mm).

What size is the Leica M10 Monochrom sensor?

36.0 × 24.0 mm (Full frame (35 mm)), an area of 864 mm² — 100% of full frame.

Is the Leica M10 Monochrom full frame?

Yes — its sensor is the same 36 × 24 mm size as 35 mm film.

How many megapixels does the Leica M10 Monochrom have?

41 megapixels (7,842 × 5,228 pixels), enough for a 26 × 17 inch print at 300 DPI.

What lens mount does the Leica M10 Monochrom use?

The Leica M10 Monochrom uses the Leica M (flange distance 27.80 mm).

How long can I expose the night sky with the Leica M10 Monochrom?

With a 20 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 12 s.
