I took a series of photos using the Minolta 500mm F8 autofocus reflex lens and my Sony a99ii. The lens is a little soft and lacking saturation and contrast but these are easily corrected in Photoshop, if required. For the photographs I took bokeh is not an issue. This is the best hiking lens for full frame cameras made to date by anyone. Try carrying my Minolta 600mm F4 in your backpack?
