Lens Description: The 135mm f/2 Apo Sonnar T* Lens from Zeiss is medium telephoto lens that offers a wide maximum aperture, vibrant color rendition and attractive out-of-focus background. It maximum aperture of f/2 provides substantial light gathering for sharp, high resolution imaging and lovely shallow depth of field photography. A nine-blade circular aperture will offer harmonious background blur when shooting with minimal depth of focus. Special anomalous partial dispersion glass minimizes chromatic aberrations in this apochromat lens and anti-reflective coating reduces reflections and ghosting. It is a compact lens for its focal length and its "floating elements" optical design consists of 11 lens elements in 8 groups with minimal glass-to-air surfaces. The lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. A rotation angle of 268º enables precise manual focusing and its all-metal barrel provides longevity and protection for its high-quality design.

I cannot fault this lens: color, sharpness, bokeh, handling, build quality… it has everything. Full aperture is fully usable and nearly as good as the others, the only obvious difference being the depth of field. This contributes to camera parameter separation: Aperture controls the DOF, speed controls the movement, and ISO controls the lighting.
