10x High Definition 2 Element Close-Up Lens for Pentax K-01 - Macro

Our review of the 10x High Definition 2 Element Close-Up Lens for Pentax K-01 finds it useful for photographers who want a quick, affordable way to get much closer to small subjects without changing lenses. The single biggest reason to buy is its straightforward screw-on design combined with achromatic optics that preserve image contrast while correcting chromatic aberration. For hobbyists shooting flowers, insects or product detail with a 52mm front thread, this close-up lens is a compact, easy-to-use option that keeps the camera's native lens performance largely intact.

Key Features

• Beveled High Definition Design: The beveled +10 close-up element improves edge-to-edge sharpness when working at short subject distances, keeping fine detail readable in macro shots.
• Two-Element Achromatic Glass: The paired high-index, low-dispersion elements reduce color fringing so images show more accurate color and less chromatic aberration.
• Fully Multi-Coated: Multi-coatings and anti-reflection layers lower flare and ghosting when shooting toward bright highlights or backlit subjects.
• Threaded Filter Mount: The lens screws onto the front of any 52mm lens like a filter, enabling instant conversion to close-up work without lens removal or complicated adapters.
• AF and IR Compatible: High speed auto-focus remains usable and the optic is compatible with infrared focusing systems, so routine focusing and metering are preserved on compatible bodies.

Who It's For

This accessory is best for amateur and enthusiast photographers using a Pentax K-01 or other cameras with a 52mm filter thread who want a fast, reversible way to explore macro photography without investing in a dedicated macro lens. It is particularly handy for field work where changing lenses is inconvenient or when carrying minimal gear is a priority.

It is not a substitute for a dedicated macro lens when highest resolving power, working distance, or focus stacking capability are required. Professionals who need extreme magnification control or optimized corner sharpness at all apertures should look elsewhere for specialty macro optics.

Pros & Cons

Pros

• Corrects chromatic aberration with two achromatic elements, yielding cleaner color in close-ups.
• Quick screw-on use for 52mm threads makes it fast to deploy in the field without lens changes.
• Multi-coating and anti-reflection treatments reduce flare for higher contrast macro images.
• Maintains high speed auto-focus and infrared compatibility on supported bodies.

Cons

• As an auxiliary close-up lens, it cannot replace the working distance and ultimate sharpness of a dedicated macro lens.

Frequently Asked Questions

Can this close-up lens be stacked with other filters?
Yes, it uses a 52mm threaded mount so it can be combined with other 52mm filters, though stacking may affect image quality and flare.

Will autofocus still work with this lens attached?
High speed autofocus remains usable on compatible camera bodies and lenses, and the optic is labeled as infrared compatible.

Does it correct color fringing?
The two achromatic elements and low-dispersion glass are designed to reduce chromatic aberration compared with a single-element diopter.
