PROMINAR MFT 8.5mm f2.8, 0.2m, 440g
The super wide angle manual lens “KOWA PROMINAR 8.5mm F2.8” has a diameter of 106 degrees. This greatly reduces TV distortion to a value of just 0.12% producing high-definition pictures and movies. Chromatic aberration is limited at the highest level due to XD lenses.
XD lenses
Kowa’s XD Lenses (extra-low dispersion glass), when combined with a concave lens possessing special dispersion properties, reduces a very high percentage of chromatic
aberration.
Dual Link Iris
A dual Link Iris system makes it possible to choose silent or click aperture adjustment. Aperture settings can be changed in an instant
Circular Aperture
The construction of the aperture blades with 9 elements makes it possible that the diaphragm shows a circle at all f-stops, creating a more natural impression.
Aluminium Alloy Body
All internal parts are protected by a solid and rigid aluminium housing.The body feels reassuringly well made with good balance and weightiness in the hand and when attached to a camera body.
Floating Mechanism System
The floating mechanism system is effective in preventing malfunction and increasing the life of the lens. High optical performance was achieved in all photographic subject distances.
Made in JAPAN
From design to inspection, these Kowa lenses benefit from our concept “Made in Japan”. At the forefront of technology, the lenses where designed and developed drawing on over 60 years of Kowa optical heritage.
