Question about Sony E 35mm f/1.8 OSS
I would like to have this lens for my Sony a6400. If I use the lens on the Sony a6400, does the focal length remain 35mm or is it multiplied by 1.5? Sorry, I come from the Nikon world and can't quite get to grips with Sony yet. The mount should fit in my opinion (both E-mount, right?). Thanks for the answer and have a nice evening :)
Helpful answer
I don't know how Nikon does it, but with Sony the focal length is the correct optical focal length. The optical ratio is independent of the sensor size. However, the angle of view depends on the sensor size - the smaller the sensor, the narrower the angle of view. You can think of it like an image section (often called electronic zoom in digital cameras, which then simply uses a smaller part of the sensor and thus becomes more pixelated).
I assume you are referring to the comparable focal length for a classic 35mm film camera (35mm camera). Since the 6400 has an APS sensor, which is smaller than 24x36mm, 35mm on an APS sensor corresponds roughly to 35*1.5= 52.5mm, i.e. roughly a normal lens.
The lens mentioned is specially made for the APS sensor (so it fits on your camera). It can also be used on a Sony full-frame camera (A7/A9...), but would then only utilise part of the sensor.
In case I have described this too complicated, there are some good Youtube videos that explain this quite clearly.
HI,
yes, both the Sony a6400 and the lens use the E-mount, so they are compatible with each other. So your assumption is correct.
Regarding the focal length: The Sony a6400 has an APS-C sensor, which has a crop factor of about 1.5x.
This means that the effective focal length of the lens on the a6400 is 1.5 times the specified focal length
corresponds. With a 35 mm lens, the effective focal length would therefore be around 52.5 mm (35 mm x 1.5).
