Question About Lens?

[ROB123]

On the information for a lens it has "The Carl zeiss Jena 35mm f2.4 M42 lens"

I know that carl zeiss is the brand jena is the model ,

now 35mm is the zoom on it, but is this the actual length of the lens aswell?

Also f2.4 this is the shutter speed isn't it? The lower the faster?

Also how do i know this will fit my camera?

Thanks again

35mm is the focal length so it's kind of like the zoom (although it isn't a zoom as it's a fixed focal length). It also isn't the physical size of the lens.

f/2.4 is the maximum aperture of the lens. Lenses don't have shutters.

It's an M42 mount lens so unless you've got a very old camera then it won't fit. It certainly wouldn't fit the Canon or Sony you've posted about previously without an adaptor ring. Lenses this old also have no electronic functions so you'd get no autofocus, no DoF preview and potentially no metering either so you'd have to do everything manually.

I take it you mean, don't buy it! There's no point!
