I know that Nikon cameras APS-C sensors has a crop factor of 1.5 but if we apply this to calculate the equivalent focal lenght in 35mm format for the Nikon P1000 camera we will not get the exact values mentionned in the specifications.

Focal lenght is 4.3mm to 539mm

Equivalent Focal Lenght is 24mm to 3000mm

3000/539= 5.58 This is not the 1.5 crop Factor of APS-C sensors of Nikon cameras.

    \$\begingroup\$ You are correct. The Nikon P1000 does not have an APS-C sensor. Did you have a question, or just this observation? \$\endgroup\$

  • \$\begingroup\$ That was a question i did not understand the crop multiplication as i thought P1000 has 1.5 crop factor because i think i have read in some comments P1000 has APS-C sensor \$\endgroup\$

The P1000 unfortunately isn't an APS-C, it's far smaller at 1/2.3-inch, which gives it a crop factor of 5.6.

Compared to a 35mm sensor it is tiny.

From ApoTelyt.com - Nikon P1000 Comparison Review

The Nikon P1000 features a 1/2.3-inch sensor and has a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the Nikon P1000 among the smaller-sensor digicams that favor affordability and compact design.

  • \$\begingroup\$ Thank you i have two questions If the tiny sensor has more megapixels will this make the crop factor even bigger ? And how they calculate the crop factor if we take these values in the picture 864mm² and 28mm² ? What is the name of the sensor used in P1000 if not APS-C ? \$\endgroup\$

    \$\begingroup\$ The name is unimportant, just call it a 1/2.3" & then avoid it like the plague. I had my eye on this camera until I discovered there are phones with bigger sensors. There's a whole lot of physics which frankly I don't understand - though there are many here who do - which basically says 'tiny sensor == bad picture'. \$\endgroup\$

  • \$\begingroup\$ @Tetsujin 'tiny sensor == bad picture' - in low light? Maybe (depends on quantum efficiency, algorithms,...). In good light? Not necessarily. \$\endgroup\$

    \$\begingroup\$ @P.Kod Megapixel have nothing to do with crop factor - it simply refers to the size of the sensor. See the field-of-view tag's information text for further information. \$\endgroup\$

It is simply that the P1000 does not offer an APS-C sensor - as its manual and marketing site state it has a 1/2.3" sensor, which offers a crop factor of ~5.5.
