Whenever you change microscopes or switch eyepieces or objective lenses, remember to repeat the FOV calculations with the new field number and magnifications. When dealing with objects observed at higher magnifications, it may be useful to convert your measurements from millimeters to micrometers. To do so, multiply the FOV diameter in millimeters by 1,000 to convert the diameter to micrometers.

Everything you need to get started shooting with the Ronin-S comes with the gimbal. A sliding camera mounting plate for attaching your camera and balancing works with the included lens support and riser to secure your mirrorless or DSLR camera of choice. USB Type-C and Type-B cables are included for camera control functions like start/stop and focus pulling (depending on camera compatibility). A 24W USB charger is included for quick-charging the gimbal. The gimbal and all included accessories can be stored inside the included case, which helps protect your equipment during storage and transport.

Knowing a compound light microscope's field of view (FOV) allows you to determine the approximate size of objects too small to measure with a standard ruler. To calculate field of view, you need to know the magnification and field number of the microscope's lens currently in use. Divide the field number by the magnification number to determine the diameter of your microscope's field of view.

Once you've taken note of the eyepiece magnification, field number and objective lens magnification number, if applicable, you can calculate your microscope's field of view by dividing the field number by the magnification number. For example, if the microscope's eyepiece reads 30x/18, then 18 ÷ 30 = 0.6, or an FOV diameter of 0.6 millimeters. If your microscope only uses an eyepiece, this is all you need to do, but if your microscope uses both an eyepiece and an objective lens, multiply the eyepiece magnification by the objective magnification to find the total magnification before dividing the field number. For example, if the eyepiece reads 10x/18, and the magnification of your objective lens is 40, multiply 10 and 40 to get 400. Then divide 18 by 400 to get an FOV diameter of 0.045 millimeters.

The DJI Ronin-S is more than just a miniaturized version of the larger Ronin gimbal stabilizers; it represents a scalable ecosystem for integrating DSLR and mirrorless cameras into professional-grade workflows. The single-handed form factor of the Ronin-S lends itself to lighter camera payloads, up to eight pounds. But don't let its size fool you; the Ronin-S has a lot going on under the hood. Separate modules are available for the handle and accessory docks, allowing you to customize the gimbal based on how you wish to operate it. While using the conventional battery grip, the Ronin-S will last up to 12 hours on a single charge.

To determine the FOV of your microscope, first examine the microscope itself. The microscope's eyepiece should be labeled with a sequence of numbers, such as 10x/22 or 30x/18. These numbers are the eyepiece magnification and the field number, respectively. Also, take note of the magnification of your objective lens at the bottom of the microscope, if applicable – generally 4, 10, 40 or 100 times.

Compound light microscopes are valuable tools in the lab. They magnify our ability to see in detail by up to 1,000 times, allowing us to study things as small as the nucleus of a cell. With them, we can determine the shape and structure of cells, observe the movements of microorganisms, and examine the smallest parts of plants, animals and fungi. Because the objects under a microscope's view are so small, it is often impossible to use a ruler to determine their size. However, calculating a microscope's field of view (FOV), the size of the area visible through the microscope, allows you to determine the approximate size of a specimen under examination.

Between the front trigger, the rear mode button, and the joystick, precise gimbal control lets you obtain the shots you require. The front trigger can lock the gimbal when held, re-center the gimbal when tapped twice, and engage the Selfie mode by turning 180° when tapped three times. Press the mode button to engage three customizable operation profiles, each with tuneable speed and response for different shooting scenarios. If fast-moving subjects are your forte, the Sport mode delivers extra-quick response times and fast gimbal movements, up to a maximum speed of 45 mph. With this operation flexibility, the Ronin-S will fit into documentary, event, and feature film workflows.
