How Crop Factor Works

Crop factor describes the relationship between a camera's sensor size and the 35mm full-frame standard. It affects field of view, depth of field, and effective light gathering.

Equivalent Focal Length Formula

To find the equivalent field of view on full frame, multiply the lens focal length by the crop factor:

Equivalent FL = Lens FL × Crop Factor

50mm × 1.5 = 75mm equivalent

Equivalent Aperture (Depth of Field)

Smaller sensors produce deeper depth of field. To find the equivalent aperture for matching DoF:

Equivalent f-stop = Aperture × Crop Factor

f/1.4 × 2.0 = f/2.8 equivalent DoF

Crop Factor Formula

Crop factor is derived from the ratio of sensor diagonals compared to the 35mm standard:

Crop Factor = 43.27mm ÷ Sensor Diagonal

43.27 ÷ 21.6 = 2.0× (Micro 4/3)

Sensor Area & Light Gathering

A larger sensor collects more total light at the same exposure settings, resulting in less noise:

Area Ratio = (Crop Factor)²

Full Frame collects 4× more light than Micro 4/3

Frequently Asked Questions

Common questions about camera sensor sizes and crop factors

Crop factor is the ratio of a 35mm full-frame sensor diagonal (43.27mm) to another sensor's diagonal. For example, an APS-C sensor (Nikon/Sony) has a diagonal of about 28.2mm, giving a crop factor of 43.27 / 28.2 ≈ 1.5×. It tells you how much narrower the field of view is compared to full frame.

Super 35 (24.9 × 18.7mm, ~1.4× crop) and APS-C (23.5 × 15.6mm for Nikon/Sony, ~1.5× crop) are very similar in width but differ in height. Super 35 is taller because cinema uses a 4:3 sensor gate area, while APS-C matches the 3:2 still photography format. In practice the horizontal field of view is nearly identical.

Multiply the actual focal length by the sensor's crop factor. For example, a 50mm lens on Micro 4/3 (2× crop) gives a 100mm equivalent field of view. A 35mm lens on APS-C (1.5× crop) gives 52.5mm equivalent. This tells you what focal length on full frame would produce the same field of view.

Yes. A smaller sensor produces deeper depth of field at the same field of view and aperture. To match the depth of field of full frame, multiply your aperture by the crop factor. For example, f/1.4 on Micro 4/3 (2× crop) gives roughly the same depth of field as f/2.8 on full frame.

The ARRI Alexa Mini uses a Super 35 sensor (28.25 × 18.17mm maximum sensor area). In common 16:9 recording modes it uses approximately 24.9 × 14.0mm. The RED Komodo also uses a Super 35 sensor. These are the most common cinema camera sensor sizes.

Crop factor is relative to the 35mm full-frame standard (36 × 24mm). Medium Format sensors like the Fuji GFX (43.8 × 32.9mm) are larger than full frame, so their crop factor is less than 1.0 (about 0.79×). This means they capture a wider field of view than full frame with the same focal length.

The RED Komodo uses a Super 35 sensor (approximately 27.03 × 14.26mm in its 6K full-sensor mode). This is slightly wider than the standard Super 35 4-perf motion picture gate but narrower in height. The effective crop factor is approximately 1.53× compared to full frame when shooting 16:9.

No. Canon APS-C sensors are 22.3 × 14.9mm (1.6× crop), while Nikon, Sony, and Fujifilm APS-C sensors are 23.5 × 15.6mm (1.5× crop). This means a 50mm lens on a Canon APS-C gives an 80mm equivalent field of view, but only 75mm equivalent on a Nikon/Sony/Fuji APS-C. The difference is small but worth knowing for precise framing.

The iPhone 15 Pro and iPhone 16 Pro main camera uses a 1/1.28" sensor (approximately 9.8 × 7.3mm), which gives a crop factor of about 3.5× compared to full frame. The ultra-wide and telephoto cameras use even smaller sensors. Despite the small sensor, computational photography compensates with multi-frame stacking, AI processing, and portrait mode simulation.
