Specs: 40-megapixel XTrans APS-C sensor, 15 fps with full AF, 4K/60fps video, dual SD cards ★ Alternatives: the X100V has a fixed 23-mm lens (35-mm equivalent in full-frame). The X100V is a
I have a 24-105mm f4 lens, if it is used on an aps-c body such as the A6400, what is the equivalent f stop, if shot wide open? f4 on a ff = ?? on an aps-c. Thank you Dave. The lens will act (for depth of of field and angle of view) like a 36-158mm f6 lens would on full frame.
Because cropped sensor cameras have a smaller sensor, the actual focal length won’t be the same as on a full-frame. To make this easier, let’s look at some examples of focal lengths: 35mm = 52.5mm on a cropped sensor. 50mm = 75mm on a cropped sensor. 85mm = 127.5mm on a cropped sensor.
It's the same 1.5 conversion so F2.8 on APS-C is equivalent to F4.2 on full frame. DOF not light if we are talking optics. It's both DOF and light. That is, for the same DOF and shutter speed, the same total amount of light falls on the sensor for all systems, which will result in the same noise for equally efficient sensors.
APS-C is closest to the size of Super-35 cinema / 3-perf 35mm (approx. 24mm x 13mm); Full-Frame 35mm is closest to the 8-perf 35mm VistaVision format (36mm x 24mm). So the focal lengths used in APS-C for typical field of view would be the same if shooting in Super-35, and if you used any PL-mount cine lenses, they would be designed to fill the
All that happens is the "equivalent" 105-300 mm lens on a full frame sensor and our 70-200 mm lens on a 1.5x APS-C sensor simply see the same field of view (and because the smaller sensor crops its view smaller, normally it would need to use a shorter lens to compensate to still show the same wider view). It's like two different film sizes, IF 0gihAu. 249 76 445 24 263 434 2 85 356
