COSINA Heliar-Hyper Wide 10mm F5.6 Aspherical VM
・ 130 ° angle of view, ultimate super wide angle The image is the largest angle of view in the world without distorting the image like a fisheye lens.Thoroughly pursuing optical performance to capture straight lines as a straight line.Distortions are thoroughly eliminated by adopting aspherical lenses. -The optical design that optimizes an incident rays angle to the sensor is used to eliminate the color covering of the peripheral part caused by the structure of the imaging device unique to digital cameras specific to digital camera.It has excellent contrast and resolution from the aperture open state to every corner of the screen. ・ Pan focus shooting The depth of field is very deep (the range of focus is wide), for example, the f5.6 is open to about 0.5m to ∞ if the focus ring is adjusted to the 2m position, and the F8 matches 1m.The focus to ~ ∞ is focused and there is almost no need to focus. ・ The shortest shooting distance is 0.5m The shortest shooting distance from the subject to the image surface is 50cm.The possibility of drawing that takes advantage of the intense perpetrive peculiar to ultra -wide -angle lenses is expanded. ・ Manual focus that allows for sure focus The adoption of a high -quality grease that produces and adjusts a high -quality metal helicoid unit and a high -quality grease that produces a moderate torque has been realized.It enables subtle focus adjustment. ・ Bayonet type VM mount A VM mount is used for the lens mount.In addition to the Vessa series (excluding Vessa L, R), it can be used with a camera that uses M mount. ・ Full -size image circle We have a margin image circle that supports 35 mm full size.In addition, it has a very compact style compared to the replacement lens for SLR.
