The Fujifilm GF 45mm f/2.8 R WR Lens is a good choice for shooting documentaries and street photography. It has a G bayonet mount and is made with 11 optical elements arranged in 8 groups. One aspherical and two extra-low dispersion elements are included in the lens design to reduce chromatic as well as spherical aberrations. These elements have a Nano GI coating applied on them to provide a clear view with minimal glare. Additionally, the optical image stabilization minimizes camera shakes. You may use this lens in temperatures as low as 14° F without any worry, thanks to its weather- and dust-resistant design.
