Feature The 135mm f/2.8 FE UMC Lens from Lightdow is a manual focus telephoto prime lens useful for portraiture and most telephoto applications. Its fast f/2.8 maximum aperture is effective in low light and enables shallow depth of field control. With a rounded 12-blade diaphragm, shallow depth of field imaging will be rendered with pleasing out-of-focus highlights. Compatible with both full frame and APS-C format cameras, this lens provides a 35mm focal length equivalence of 202.5mm when used on APS-C cameras. Its minimum focus distance is 2.6'. The optical design includes one extra-low dispersion lens element to control chromatic aberration, contributing to sharp, color-accurate imaging, and each of its lens elements features Ultra Multi-Coating to improve light transmission and reduce ghosting and flare. An internal focus system prevents the front end from rotating which allows more effective use of variable filters.
