Kase Lens 85mm 1.4 AF Nikon Z
Premium design and lightweight
The main body of the lens has a molded design for better tactile feel and significant weight reduction.
The back of the lens is made of metal for firmer attachment to the camera.
The front of the lens has a molded design for a good feel of the focus ring. The metal aperture ring on the back provides instant feedback when adjusting aperture settings.
Weight of lens with Z mount: 580 g (including lens hood is 610 g)
Lens design with magnetic attachment
The lens cap features a magnetic attachment design, which protects the lens 360 degrees all around, provides better protection, is dustproof and easier to attach and remove. It avoids the problems of loose snap caps and dust intrusion with two-point snap designs.
Magnetic filters can be attached directly to the lens, providing a more convenient way to use filters.
Design with two customizable function buttons
Kase designed two customizable buttons on the lens. The FN2 button is set to the minimum focusing distance. A single press switches the lens to the minimum focusing distance and a long press locks the current focusing distance. This feature provides more convenient and faster operation.
Aperture switching: position A defaults to maximum aperture F1.4
The aperture adjustment ring has precise click stops for each aperture setting, making it easier to set the desired aperture. When set to position A, the aperture automatically switches to maximum aperture F1.4, so there is no need to reset it. Every detail is designed with user convenience in mind.
Optical design: 10 groups of 13 elements
Excellent image quality, superior image resolution and true-to-life color reproduction. Even at the fully opened aperture of F1.4, the image remains clear and sharp. The use of elements with low dispersion and high refractive index significantly improves the optical quality of the lens and reduces glare and ghosting. Even in backlit conditions, the lens can produce high-contrast, high-definition images with high color accuracy. Preferably, use the lens hood to reduce glare.

Kase Lens 85mm 1.4 AF Sony E
Premium design and lightweight
The main body of the lens has a molded design for better tactile feel and significant weight reduction.
The back of the lens is made of metal for firmer attachment to the camera.
The front of the lens has a molded design for a good feel of the focus ring. The metal aperture ring on the back provides instant feedback when adjusting aperture settings.
Weight of lens with E mount: 580 g (including lens hood is 610 g)
Lens design with magnetic attachment
The lens cap features a magnetic attachment design, which protects the lens 360 degrees all around, provides better protection, is dustproof and easier to attach and remove. It avoids the problems of loose snap caps and dust intrusion with two-point snap designs.
Magnetic filters can be attached directly to the lens, providing a more convenient way to use filters.
Kase Magic Filter only for Sony E
Effectively regulate light exposure, in environments with sufficient light, the shutter speed is likely to be too fast when using a wide aperture, affecting the video viewing experience. With the Kase magic filter for large apertures, you can slow down the shutter speed and ensure the smoothness of dynamic shots.
Design with two customizable function buttons
Due to the limitations of SONY cameras' custom button settings, only one function can be assigned to a custom button on E-mount lenses. Based on feedback from many photographers, Kase designed two customizable buttons on the lens. The FN2 button is set to the minimum focusing distance. A single press switches the lens to the minimum focusing distance and a long press locks the current focusing distance. This feature provides more convenient and faster operation.
Aperture switching: position A defaults to maximum aperture F1.4

Kase Reflex Lens 200mm 5.6 Canon EF
This lens is optimized for use with the full-frame Canon EF mount, but is also suitable for SLRs with an APS-C sensor.
The entire composition has a donut effect on the bright part of the depth field. This lens is completely manual and therefore does not work with the automatic on your camera.
The center of the lens has a reflective mirror so that when the background is out of focus, the dotted light on the background appears as a donut effect.
2. Bokeh background and shallow depth of field
The donut effect appears in the bright part of the depth field
3. Low color rendering and fog effect
Show neutral colors and the edge of the main subject is soft but not blurry.
4. Light and convenient
Light and compact, easy to carry
5. Get to know more shooting scenarios
Widely used in floral, portrait and landscape photography
1. Maintain a certain distance while taking photos.
The focus point (subject) must be a certain distance from the landscape in front and behind so that the donut effect will be visible. Don't get too close to the background.
2. Choose a well-lit environment for the background.
When shooting, choose an environment with sufficient light and a background with dotted light, such as leaf reflections, light leakage in the gaps between the leaves, ripples on the water surface, various background dots, white dots, reflective dots, etc., so that the donut effect is even more obvious will be.
3. The greater the light ratio, the stronger the contrast.
The greater the light ratio, the stronger the contrast and the more brilliant it will be.
4. Find a good background and take pictures of the subject.
When composing a photo, you can first look for interesting small circles of light and then add the main subject.
5. Screen focus.
When focusing, you can zoom in on the screen to focus, or set the focus color reminder in the camera to focus.
6. Adjust the shutter speed.
Make sure the shutter speed is configured accordingly. (Adjust the ISO parameter to configure the shutter speed.)
7. Recommended device.
It is recommended to use a tripod and shutter cable together with the lens.
8. When you control the depth of field, you can move forward and backward to get the effect you want.
Because this is a prime lens, you can't zoom in and out, but have to move forward and back to find the sweet spot for the best effect.
