This is why 35mm at F2 on an APS-C sensor will produce a wider (more in focus) depth of field in comparison to a 50mm at F2 on a full frame sensor, even if the focal length appears the same. Because technically, it's like you’re shooting a full frame 35mm F2 lens on the APS-C camera, just cropping it 1.5x due to the APS-C sensor being
It offers a full-frame equivalent focal length range of 15-30mm, making it an ideal choice for vlogging and content creation. With its compact and lightweight design, this lens is perfect for everyday shooting applications and is particularly well-suited for use with APS-C mirrorless cameras like the Sony ZV-E10. The focal length and field of view is the same for EF and EF-S lenses on the same camera. however, when reading a lens review that was made on a FF camera, note that the overall experience of that lens on a crop camera may be different (for example, I love the 70-200 on full frame, but rarely use it on my 7D as it gets "quite long" on that camera).The 35mm lens has a 35mm focal length, while the 50mm lens has a 50mm focal length. This does not single-handedly determine how wide your photo will be, hence the field of view. The field of view is also dependent on the sensor size, and a wider sensor will obtain light from a wider area, giving you a wider field of view.
Remember, the focal length given represents the result on a full frame body. Let’s take the example of a 50mm. It doesn’t matter if it was originally designed for APS-C or FF format, the focal length of a lens doesn’t change. It is the field of view that varies depending on the size of the sensor on which you place the lens.
