Most microscopes come with at least three objective lenses, which provide the majority of image enhancement. The function of objective lenses is to magnify objects enough for you to see them in great detail.

Smooth focusing ensures precise control and produces images with incredible sharpness, making it the ideal choice for indoor and night shooting.

The Preset Aperture Control function operates only when shooting video(Movie mode) and the focusing mode of the camera is set to AF mode. Please set the aperture at f/1.8 before switching the "Custom Switch" to "Mode 2. It is recommended to set the "Exposure mode" as A mode (Aperture Priority AE) or M mode (Manual Exposure).

Before you use a microscope, it helps to know what all the different parts are for. Many people believe that the objective lenses are the most important components of a microscope. Basically, without them, your microscope experience would be very disappointing.

It is an extra-wide-angle manual focus lens designed for APS-C crop sensor mirrorless cameras. With low distortion and wide angle, photographers who want wide-angle photos such as landscape and architectural images can create satisfactory images. F2.0 is very bright so it captures clear and vivid images even in relatively dark environment. For the first time in Samyang Optics history, the independent NCS(Nano Coating System) technology was used. It creates even lower reflection rate than the original UMC (Ultra Multi Coating) and higher contrast. Also, the light penetration rate is very high to minimize flare and ghost. Optical construction of Samyang 12mm F2.0 NCS CS features 12 elements in 10 groups – among lenses, there are 1 aspherical lens(AS), 1 hybrid aspherical lens (H-ASP) and 3 extra-low dispersion lenses(ED) to provide high image quality. H-ASP minimizes color aberration to realize exceptional image quality and high contrast for center and corner of the image even when its aperture is fully opened. ED lowers unnecessary light dispersion to drop color aberration effectively. With such optical construction, it has 0.2m of minimum focal length. There are 6 aperture blades designed to be almost as a full circle when aperture is closed which expresses starlike ray clearly and beautifully in deep depth of field images. The frame of Samyang 12mm F2.0 NCS CS is compact and solid since it is made of high-strength aluminum alloy. Trustworthy images can be captured even under inferior environment. Also, petal-shaped lens hood to shelter lens from unnecessary light is provided. Available for 5 camera mounts: Canon M, Sony E, MFT, Samsung NX, Fujifilm X ※ Size and design may vary depending on the mount of a lens

The best standpoint from which to appreciate the full view of a subject is the distance of the diagonal length of the subject frame. This wider angle is superior to standing closer at a 50 degree angle to get a more detailed view. This notion of an ideal distance or view point is also applicable in the world of photography.

The perfect spacing and distance are always necessary when shooting all kinds of subjects, including people, to give them a proper relationship with the beautiful space around them. So, what’s the exact distance that helps you best appreciate a work of art, or a photo?

On the Preset Aperture Control function, the aperture blade operates smoothly like a "De-clicked lens", which is advantageous for video recording. Fujifilm cameras are engineered to control the aperture according to the minimum exposure value(F-stop), so when the camera controls the aperture, it blinks momentarily to set the proper exposure.

For still images, keeping a distance equal to the diagonal length of the full image surface is recommended. The full frame sensor of a digital camera is 36 x 24mm and the diagonal length is 43.26mm so any distance close to this number is nearer to the ideal than the currently accepted industry standard of 50mm.

The longest objective lens is an oil immersion objective lens, which magnifies 100x. The total magnification is 1000x if the eyepiece lens is 10x power. The oil immersion objective lens is used for examining the detail of individual cells, such as red blood cells. This lens requires a special oil to form a link between the edge of the objective and the cover slip. Before you use an oil immersion objective lens, ensure the specimen is in focus under the high-power objective lens. After you remove the high-power objective, put a tiny amount of oil onto the cover slip above the specimen, and then move the oil immersion lens into position.

Back when film cameras were common, 45mm was the industry standard and this continued as reflex cameras needed extra space to fit a mirror. However, as mirrorless cameras become more popular again, there has been a need to return to this industry standard…which is the impetus for the Samyang AF 45mm F1.8 FE. With less distortion than a 35mm lens and wider angles than a 55mm lens, the Samyang AF 45mm F1.8 FE is a perfect lens for portraits, landscapes, architecture photography, and pictures of pets.

AF 75mm F1.8 X intentionally disconnects the communication with the camera body and the lens itself on the Preset Aperture Control function, so it is possible to smoothly adjust the exposure without flickering. ISO and shutter speed are adjusted according to the changed exposure by controlling the aperture, so the exposure value can be changed even with the 1/2 F-stop.

A scanning objective lens that magnifies 4x is the shortest objective and is useful for getting a general overview of a slide. A low-power objective lens magnifies 10x, but remember that it is coupled with an eyepiece lens, so the total magnification is 10x times the power of the eyepiece lens. A high-power objective lens magnifies 40x, with total magnification 400x if the eyepiece lens is 10x power, and it is ideal for observing very fine detail, such as nerve cells in the retina or the striations in skeletal muscle.

Every microscope has an eyepiece lens, which is the lens at the top that you look through. A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. The eyepiece lens is usually 10x or 15x power (i.e., what you look at appears to be 10 times or 15 times closer than it actually is). A rotating nosepiece or turret holds two or more objective lenses, and you can easily switch between them to change power. A microscope's stage is the flat platform that holds the slides. Some microscopes also have a condenser lens, which focuses the light onto the object, and a diaphragm or iris, which is a revolving disk with holes of varying sizes. The iris is used to vary the intensity and size of the light that is streamed upward into the slide.

[What is Dolly shot?] A dolly shot, also referred to as a tracking shot or trucking shot, is a camera movement technique used by cinematographers to track and follow a subject in motion. To achieve this, the camera is mounted on a device called a "dolly," which facilitates smooth tracking movement. The dolly can move in front of, behind, or alongside the subject, which can be a person, a location, a product, or any other object of focus in the frame. Through this, you can control the emotional distance between the subject and the viewer by highlighting the audiovisual and dramatic effects.

[How to take a Dolly Shot simply by handheld] Tip. If the moving distance is long, the camera may shake, so please shoot at a focal length between 35 and 100mm. 1. Stand at a distance of about 1.5 to 2 meters away from the subject. 2. Set the custom switch to MF and Mode 3 and adjust the focal length to about 100mm. 3. After focusing on the subject, set the aperture to F8~16. 4. Slowly turn the zoom ring to the left (towards the wide-angle end) while using your upper body and arms to move the camera toward your subject. 5. Dolly Shot complete! ※ When shooting from a farther distance from the subject, use a cart or gimbal for more stable shooting.

Featuring 6 rounded blades, it adds an artistic touch to your pictures and creates a sense of soft dimension with incredible bokeh, perfect for out-of-focus portraits and night city landscapes.
