Main concept of MILTOL system

Kenko Tokina developed MILTOL as a system of interchangeable optical elements and accessories on the basis of T-mount adapter. Thus, MILTOL 400mm F6.7 ED can be used with any DSLR or non-reflex cameras. Moreover, using different optical adapters like Scope Eyepiece or Zenith mirror this lens can be converted into spotting scope or telescope. In Kenko MILTOL 400mm F6.7 ED Kit T-mount adapter (for Canon or Nikon) is included.

Overall optical performance

Optical system with minimum optical elements ensures minimum chromatic aberrations, that are specific for tele lenses. Thanks to high optical quality Kenko MILTOL 400mm F6.7 ED tele lens will give you the best result you can expect from the lens of similar category.

miltol_400_3 ED - Extra Low Dispersion Glass is used to reduce chromatic aberrations. Since average glass has a different refractive index for different light spectrum rainbow color aberrations on the edges of objects may occur. For this reason the image can be unsharp and fuzzy. The use of Extra Low Dispersion Glass minimize these negative effects and make image clear and sharp.

Multi coating and Extra Low Dispersion glass provides excellent resolution and contrast of the image. F6.7 helps to achieve good depth of focus field and useful in dark conditions.

Focusing

Kenko MILTOL 400mm F6.7 ED can focus only manually using wide with excellent rubber grip focus ring on the body of the lens. The rotation of focus ring is very smooth. Rotation range is 262 degrees. In spite of long focal length focusing process will not take much time.

Rotation of focus ring is smooth from "near" to "far" even in low temperature environment. There is no any sucking sound while rotating the focus ring, so there is no chance for dust in the air to be sucked inside the lens. Manual focus will be a good school for beginners and raise nostalgic feelings in the minds of elder generation photographers.
