This new lens joins the current family of interchangeable GF Lenses, designed for the GFX large format Camera System and covers some of the most frequently used focal lengths by photographers. The GF45-100mmF4 R LM OIS WR lens has an equivalent focal length range of 36mm and 79mm on a smaller 35mm format system, a maximum aperture of F4 and is a natural fit with two other GF Zoom Lenses--the GF32-64mmF4 R LM WR and the GF100-200mmF5.6 R LM OIS WR. Together, these three lenses provide photographers with a broad range of focal lengths, accommodating a wide range of shooting styles and enabling them to become incredibly versatile and creative.
