The Sony NEX-7 sensor (highlighted) drawn to scale against common formats. Its area is 42% of a full-frame sensor, which collects about 1.2 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 1.54 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 3.90 µm pixels, diffraction starts to soften pixel-level detail around f/5.8. For maximum sharpness keep landscapes between f/3.2 and f/6; stopping down further trades detail for depth of field.

Maximum print sizes#

At 24.3 MP the Sony NEX-7 produces 6,000 × 4,000 pixel images. See the 24 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 Sony NEX-7?

The Sony NEX-7 has a crop factor of 1.54× relative to 35 mm full frame (diagonal 28.1 mm vs 43.3 mm).

What size is the Sony NEX-7 sensor?

23.4 × 15.6 mm (APS-C), an area of 365 mm² — 42% of full frame.

Is the Sony NEX-7 full frame?

No — its sensor is APS-C, which is 2.4× smaller in area than full frame.

How many megapixels does the Sony NEX-7 have?

24.3 megapixels (6,000 × 4,000 pixels), enough for a 20 × 13 inch print at 300 DPI.

What lens mount does the Sony NEX-7 use?

The Sony NEX-7 uses the Sony E-mount (flange distance 18.00 mm).

How long can I expose the night sky with the Sony NEX-7?

With a 13 mm lens (20 mm equivalent) the 500 rule gives 25 s and the stricter NPF rule at f/2.8 gives 17 s.
