A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

does full frame has benefits ob shutter speed on equivalent focal length and aperture? (alien.top)

it is said that full frame aperture equivalent of 2.8 to aps-c is 4.2. does it mean that shutter speed of aps-c is one stop slower that full frame on the same aperture? given the same focal length equivalent e.g. aps-c 23mm and ff 35mm.

Only in terms of depth of field, assuming you are matching field of view.

No. Unless maybe you're talking about comparing the same ISO noise level. But if so, it's more complicated than that.

what confuses me is aperture diameter in aps-c 23mm f/1.4 is 16 while 35 in f/1.4 is 25. we all know that the bigger the aperture diameter, the more light comes inside the sensor, the more light, means faster shutter speed.

aperture diameter is a part of mechanical (size) that affects the light.

Aperture scales at the same scale as the sensor size so it’s a wash.
