Refined design using aluminium outer casing and comfortable sense of operation
A new sleek machined aluminium outer casing is used for a refined lens appearance. The focus mechanism has been completely revised to enable smooth focusing when using the manual focus and a comfortable sense of operation. The hood is made of plastic.

Simple drip-proof construction for high reliability even when outdoors
This lens uses a simple drip-proof construction to prevent water from getting inside the lens. Combined with PENTAX digital SLR cameras using a drip-proof construction enables use in rainy or foggy conditions or other locations exposed to water for enhanced durability and reliability.

High delineation performance
This lens has a focal length equivalent to 153mm in the 35mm film format.
The FREE (fixed rear element extension) focusing system is used to minimize ghosting and flare and provide clear, high-quality images from the infinity end to macro distances. Closeups up to a maximum of 1:1 (1X) are possible. The working distance is longer than the macro of 50mm for enabling effective shooting of subjects that are difficult to approach.

Round iris diaphragm for natural out-of-focus (bokeh) effect
A new round iris diaphragm is used from open to F5.6. This reduces the beams of light when shooting point light sources to enable a more natural out-of-focus (bokeh) effect.

SP (super protect) coating
A SP (super protect) coating is used on the front lens for repelling water and oils to enable shooting with peace of mind even in outdoor environments.

Quick-Shift Focus System
If you turn the focus ring after focusing by the AF, focusing instantly switches to the manual focus. This enables smooth focusing operations without the need for a switching operation.

In short, the Pentax 100mm f2.8 SMC D-FA WR Macro Lens is a must-have for any serious photographer looking to capture stunning, detailed images in any condition.

Understanding: Aperture

Aperture is the opening in a camera lens that controls how much light enters the camera. It's measured in f-stops like f/2.8 or f/8. Lower f-stop numbers mean wider openings, letting in more light and creating a shallow depth of field (blurry background). Higher f-stop numbers mean smaller openings, letting in less light and creating a larger depth of field (more of the scene in focus). Aperture also affects the quality of out-of-focus areas in the image (bokeh).

Understanding: Lens Types

Different lenses have different purposes to achieve different styles of images, some popular ones include:
Prime Lens: Fixed focal length, sharp images, great for portraits and dark settings.
Zoom Lens: Variable focal length, versatile for different shots and everyday use..
Wide-Angle Lens: Captures wide scenes like landscapes.
Telephoto Lens: Magnifies distant subjects, ideal for sports & wildlife.
Macro Lens: Perfect for close-up photography of small subjects.
Fisheye Lens: Ultra-wide perspective, creates unique images.

Understanding: Lens Mounts

Different camera brands use different lens mounts, which are like connectors that attach lenses to camera bodies. Each mount is specific to a particular brand and camera series. For example, Canon uses the EF and RF mounts, Nikon uses the F mount, Sony uses the E mount for its mirrorless cameras. These mounts dictate which lenses are compatible with which cameras. Some brands offer adapters to use lenses from other systems, but it's essential to ensure compatibility for proper functionality and autofocus performance.

Understanding: Manual and Autofocus

Manual focus and autofocus are two ways to adjust the sharpness of a camera lens. With manual focus, you turn a ring on the lens to bring the subject into focus yourself, giving you full control over what appears sharp in the image. Autofocus, on the other hand, relies on the camera's built-in technology to automatically adjust the focus for you, usually by detecting contrast or phase differences in the scene. Autofocus can be convenient, especially for fast-moving subjects or when you need to capture a quick shot, whereas manual focus allows for precise adjustments and creative control over the final image.
