This 100mm f/2.8 lens features a Pentax K mount, and is compatible with full-frame sensors or APS-C sensors, where it will provide a 150mm equivalent focal length.

A bright f/2.8 maximum aperture is useful for working in a variety of lighting conditions and the minimum f/32 aperture helps to attain a long depth of field when working with close-up subjects.

One high refractive index element and one extra-low dispersion element help to control chromatic aberrations and minimize distortions throughout the focusing and aperture ranges.

An Ultra Multi-Coating has been applied to lens elements to reduce lens flare and ghosting for increased clarity, contrast, and color fidelity.

Featuring a macro design, this lens affords a 1:1 maximum magnification ratio along with a minimum focusing distance of 1'.

Benefitting working with especially close subjects, this manual focus lens features an internal focus design to maintain the overall lens length during use. Additionally, the front filter mount does not rotate when focusing to better enable the use of polarizers, graduated ND, and other filter types that require precise positioning.

A rounded nine-blade diaphragm contributes to a pleasing out-of-focus quality when using selective focus or shallow depth of field techniques.

This lens features a mechanical aperture coupling that permits the use of aperture priority and automated exposure modes, as well as the ability to control the aperture setting with Pentax DSLRs.

Q: 7. Is the lens so heavy that it needs a support when using with the Sony A6000? If it doesn't come with a tripod collar, so how would you support it?

A: This lens is very heavy. It does not need a support however. Usually when I shoot with this one, I hold the lens instead of the camera body (hard to explain, but the lens takes the weight, not the body.) I spite of the weight, this is a spectacular lens. The color and sharpness are vibrant. The bokeh is just the softest (even with high f stop). Worth the weight.
