Manual Focus Lenses
Smart design for an advanced manual focus family
We have applied our experience in the design of compact and lightweight thermal imaging optics to the manual focus requirement for handheld applications.
The result is a growing family of smart manual focus lenses, available off-the-shelf.
Manual focus lenses are especially suitable for systems where the user wants to achieve the sharpest image possible whether the object is close by or far away.
Typical applications are wildlife spotting scopes or handheld surveillance systems.
Our lenses have an attractive black anodized finish, and smooth and positive focusing action.
They interface to the camera body with an M34 x 0.5 (6g) fitting. Both HEAR and iDLC® versions are available, though we recommend the iDLC® hard coating for standard handheld use.

Barrel focus ring versus top focus knob
We offer two different focus mechanisms. Focus rings are the most common focusing system but when the lens diameter is larger, a focus knob provides a more comfortable option.
The focus knob can be positioned anywhere on the lens barrel when the camera is assembled. That could be top, right, left, or anywhere in between. This flexibility is specifically intended to maximise the ease of use.
Both focus mechanisms have a visible marking to indicate the direction of movement to infinity.
