Exclusive design with performance and functions that meet the expectations for mirrorless systems by leveraging the short flange back.

In this article we will explain what a spectral camera is and how it works, and its different uses and applications for drones.

Because each pixel records different information, a variety of data can be captured and results can be obtained for specific analyses, which can be useful for a variety of purposes.

Multispectral cameras work by using specialized sensors that can detect radiation in different bands of the electromagnetic spectrum. The multispectral sensor is composed of several pixels sensitive to different wavelengths, meaning that each pixel is designed to detect the amount of radiation in a specific band of the spectrum.

Drones in agriculture with spectral cameras are a valuable tool for farmers in making the right decisions in the management of their crops, as they offer the following benefits:

This service converts specifications of the mount of SIGMA lenses to that of a different camera body. Users can “tailor” their favorite lenses to the camera body if they plan to get a new one in the future. This allows continued use of their favorite lenses over the long term regardless of the camera system.

Precision agriculture is one of the most relevant uses for drones with multispectral cameras. By having a multispectral camera for environment and agriculture, they offer farmers the ability to manage their crops, soil, fertilizer and irrigation more efficiently.

Fully compatible with in-camera aberration correction (corrections for peripheral illumination, chromatic aberrations, and distortion). By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.

On the other hand, a thermal imaging camera captures infrared radiation emitted by objects. This makes it possible to visualize temperature differences and create thermal images.

A multispectral camera captures images in different bands of the light spectrum, beyond what our eyes can see. This means that it can capture information in colors that we cannot normally perceive.

With the AF drive control program and high-speed communication tuned for each lens, shooting at speed with high-precision AF control is achieved. The lenses also support the AF-C mode.

Making the lens mount native provides a much more rigid and stable feel to the lens than using an adapter. Featuring a surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.

At UMILES University we give you the opportunity to train professionally through our complete drone pilot course, but you can also specialize through the course of precision agriculture with drones, so you can master everything related to the use of drones and their various components, such as multispectral cameras that have become essential elements for this field of application.

As we have mentioned in previous articles, the uses of professional drones have been expanding more and more thanks to the wide range of advantages they offer. One of the most outstanding features of drones is that they allow to adapt different elements to improve their performance, and multispectral cameras are an important part of these components.

As its name suggests, it is a type of camera that has the ability to capture different spectra or images beyond the range visible to the human eye. This is because they can detect radiation in different wavelengths or spectral bands, such as near infrared (NIR), mid-infrared (MIR) or thermal infrared (TIR).

Multispectral cameras and thermographic cameras are two types of cameras used for different purposes, so the main difference between them is the type of information they capture.

The L-Mount Alliance is a partnership between Leica Camera, SIGMA, Panasonic, Ernst Leitz Wetzlar GmbH and, more recently, DJI. Its aim is to provide photographers with one unified lens mount standard. Developed by Leica Camera, the L-Mount allows photographers to combine lenses and cameras made by the five Alliance partners. A new era of creative freedom has begun.

Compatible with in-camera image stabilization, the camera automatically detects the focal length of each lens and optimizes image stabilization performance.
