Questions & Answers

DANIEL H : I have used the Nikon version to make a nice telescope from an old Tamron 500mm lens. Picked out 3 stars in the Trapezium on average seeing. I have a Vivitar Series 1 210 FD mount that's another likely candidate. It's old but should make a reasonable scope. Will this fit the FD mount? Will I need a FD/EF conversion mount? If so, can you recommend something?
Ivo K : Will the image be inverted?
Edwin D : Will this lens fit a Canon EOS 70D and if so what kind of magnification can I expect? Thank You ahead of timeANDREW R : Does NOT mount on a camera. Uses Canon EF mount lenses to create a "spotting scope". Magnification would very depending on the lens mounted.

About Kenko K-LS10-CESB

Enhance your photography experience with the Kenko Lens2Scope Adapter for Canon EF Mount Lenses - Straight Eyepiece. This innovative accessory transforms any Canon EF Mount lens into a high-performance spotting scope, offering a versatile solution for photographers and nature enthusiasts alike.

Constructed with a lightweight composite body, the Lens2Scope Adapter is designed to house a top-tier roof prism, advanced optics, and an eyepiece akin to a traditional spotting scope. When attached to a lens, it seamlessly converts it into a spotting scope, perfect for detailed viewing and observation.

The lens mount and the housing for the optics are crafted from robust metal, ensuring durability and longevity. Meanwhile, some external barrels are made from high-quality polycarbonate, contributing to the adapter's overall lightweight design.

The Lens2Scope Adapter's optics are engineered to magnify the image by a factor of 10x. This means that a 100mm lens, when used with the Lens2Scope, delivers the same magnification as a 1,000mm lens, providing exceptional viewing clarity.

Focusing is a breeze with this adapter, thanks to the convenient use of the lens' manual focus ring. For extended viewing sessions, the Lens2Scope Adapter comes with a removable tripod adapter, allowing for easy mounting onto a tripod.

Despite its powerful capabilities, the Lens2Scope Adapter is compact and portable. It comes with its own carrying case and occupies roughly the same space in a camera bag as a standard lens. This makes it an ideal companion for photographers on the go, ensuring that superior viewing capabilities are always within reach.
