Mr. Ueno: Yes. The maximum aperture of XF18-55mm is F2.8 at wide and F4 at telephoto. A typical kit lens is F3.5-5.6, but that wouldn’t create enough bokeh nor photographic expression for an APS-C sized sensor.
We made it f/2.8 to achieve both brightness and high image quality. Consequently the cost would be higher, so there was the problem with the price even though we wanted a wider range of people to use our product. This is why we then created the XC lens “XC16-50mm” and “XC50-230mm” as the beginners’ model. The only difference is the material used for the lens exterior. The inside is the same optical design and technology as the XF lens.
