Questions & Answers

Robert M : for full frame pentax k-1??MICHAEL T : This adapter turns your K-mount lenses into a telescope. Should work with any K-mount lens, though it's pointless on normal to wide lenses. Works quite well on a 200-300mm lens. The camera you take the lens off of is irrelevant. I've used mine with a 200-mm Tokina zoom I bought for my ME Super, which of course is a full-frame 35mm camera.JUSTIN D : This is an attachment for a lens and has nothing to do with the camera or its sensor size. It attaches to the lens and then you look through it like a telescope. Only thing that makes it "for Pentax" at all is the physical size and specifications of the mount.

Optically good, but....

Works very well. Good eye relief. Very clear and bright. Marginal build quality. I would not trust the tripod mount. I use it but only with a small lens. I would have paid more for better built unit.

Does the job, but rather poorly

This is an interesting item that turns any camera telephoto lens into a spotting scope. While the ideal has been intriguing to me for a long time since I have a spotting scope and many long telephotos. I acquired this item to test its performance....namely a Zeiss 30x60mm spotting scope versus some nice Pentax SMC Takumar 300mm and 500mm prime telephotos. While the Zeiss spotting scope has always been an outstandng performer, I was surprise to see that the optics provided with the Kenko adapter maybe compromised when converting a high end telephoto into a spotting telescope. The image quality was soft and difficult to focus properly through this optic (I realize the focusing is done with the telephoto) and may represent the weakest link in the optical train. I am very disappointed that I cannot effectively turn some excellent telephoto lenses into excellent telescopes.Also the plastic attachment for tripod attachment is plastic and is totally useless in that it flexes and is effectively worthless when using any telephoto with any weight.. Don't even bother with attaching to a tripod via this mounting mechanism.

About Kenko K-LS10-PKAB

Where innovation meets versatility, the KENKO Lens2Scope Adapter is a transformative accessory designed for Pentax mount lenses, offering a seamless transition from photography to spotting scope functionality. This adapter is a must-have for astrophotography enthusiasts and nature observers who wish to extend the use of their existing lens collection.

Crafted with precision, the Lens2Scope Adapter features a robust metal lens mount and housing that encase a high-quality roof prism and optics, akin to those found in traditional spotting scopes. The external barrels, constructed from durable polycarbonate, ensure a lightweight yet sturdy design, making it an ideal companion for fieldwork.

The optics within the Lens2Scope magnify the image by a factor of 10x, transforming a 100mm lens into the equivalent of a 1000mm lens for powerful, up-close viewing experiences. Achieving sharp focus is effortlessly accomplished using the manual focus ring of your Pentax lens.

This model boasts an angled eyepiece, enhancing comfort for users, especially those who wear glasses or prefer an alternative to the straight eyepiece design. The angled eyepiece also facilitates an ergonomic viewing position, reducing strain during prolonged observation sessions.

The Lens2Scope Adapter is compatible with a range of Pentax mount lenses, making it a versatile choice for photographers looking to maximize their gear without the need for additional, bulky equipment. The adapter's removable tripod adapter supports secure mounting onto a tripod, accommodating up to 800g for stable, hands-free viewing. For heavier lenses, it is recommended to utilize the lens's own tripod mount to ensure optimal support.

Included with the Lens2Scope Adapter is a convenient carrying case, allowing for easy storage and transport alongside your camera equipment. This compact accessory occupies minimal space, comparable to that of a standard lens in your camera bag.

Elevate your visual exploration with the KENKO Lens2Scope Adapter for Pentax Mount Lenses - Angled Eyepiece, where high-quality optics and user-friendly design converge to offer an innovative solution for photographers and observers alike.
