Q: 1. what does "23mm (35mm Equivalent)" means?

A: All Fujifilm cameras have a smaller sensor than a frame of 35mm film. For this reason all lenses have a 1.5X crop factor. So a 23mm lens on a Fujifilm camera will have the angle of view of a 35mm lens on a 35mm film camera.

Q: 2. Is the manual focus a "wire focus"? I mean, what actually rotates the focusing mechanism: a motor or your hand?

A: This lens is focus by wire.

A: The Voigtlander Nokton 23mm f/1.2 Aspherical Lens for FUJIFILM X is a manual lens and the FUJIFILM XF 23mm f/1.4 R LM WR Lens supports autofocus. So most prefer a lens with autofocus and would go with the Fujifilm brand one.

Q: 8. Would this be a good travel lens? The older 1.4 was very light and compact.
