As an avid hiker in the northeast part of the United States (NH and ME), I consider this an ideal lens. With the twist of the aperture ring I can either capture what I see in front of me on the trail, or isolate something that has caught my eye, both of which will have incredible sharpness, wonderful bokeh, or both. Additionally, the inherent sharpness of this lens allows me, via cropping, to capture details of distant peaks. I could not n=be happier with this lens.
