Very sharp, and works well with in-body stabilisation, which is more noticable/effective at this focal length. Suprisingly good bokeh! This has now become my default lens bushwalking, with a shorter macro and wide prime in the bag. Very versatile thanks to close minimum focus distance. Not as big as imagined. About as heavy as expected (not light, but probably good for this class of lens). Overall GREAT and well worth the investment." bhphotovideo.com | Great telephoto lens | | 300 mm | | | Focus motor | Pentax SDM | | | Aperture | f/4 | | | | | Zoom range | 1x | | | Max focal length | 300 mm | | | | | Min focal length | 300 mm | | | Length | 183 mm | | | | | Fixed aperture | n/a | | | Weight | 1.1 kg | | | | | | | | | Focus motor | Pentax SDM | | | Aperture | f/2.8 | | | | | Zoom range | 2.7x | | | Max focal length | 135 mm | | | | | Min focal length | 50 mm | | | Length | n/a | | | | | Fixed aperture | Yes | | | Weight | 0.7 kg | | | | | | | | | |
