Nikon E3

The Nikon E3 is a DSLR from 1998 with a 2/3" sensor measuring 8.8 × 6.6 mm. Its crop factor is 3.93×, so a 50 mm lens frames like 197 mm on full frame. Every number below is calculated for this exact sensor.

The Nikon E3 sensor (highlighted) drawn to scale against common formats. Its area is 7% of a full-frame sensor, which collects about 3.9 stops less total light at the same exposure.

Focal length equivalents & field of view#

Multiply any focal length by 3.93 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.

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. (NPF needs a known resolution and is omitted here.)

Focal length500 rule
4 mm (16 mm eq.)31.8 s
5 mm (20 mm eq.)25.4 s
6 mm (24 mm eq.)21.2 s
9 mm (35 mm eq.)14.1 s
13 mm (51 mm eq.)9.8 s

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 Nikon E3 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 × 3.93.

Frequently asked questions#

What is the crop factor of the Nikon E3?

The Nikon E3 has a crop factor of 3.93× relative to 35 mm full frame (diagonal 11.0 mm vs 43.3 mm).

What size is the Nikon E3 sensor?

8.8 × 6.6 mm (2/3"), an area of 58 mm² — 7% of full frame.

Is the Nikon E3 full frame?

No — its sensor is 2/3", which is 14.9× smaller in area than full frame.

How long can I expose the night sky with the Nikon E3?

With a 5 mm lens (20 mm equivalent) the 500 rule gives 25 s.
