Canon announced the launch of four new RF lenses for use with the newly developed RF mount — the core of Canon’s new EOS R System. The four lenses, built on the unique characteristics of the RF Series, comprised of Canon’s initial lens offering.

The RF mount’s first true macro lens, the RF100mm f/2.8L Macro IS USM, is not only capable of more than life-size magnification, it also offers new functionalities such as a Spherical Aberration control ring.

A zoom lens is one of the most versatile types of lenses available. You can simply turn the zoom ring to change your framing. This makes them convenient, versatile, and easy for even beginners to use. It’s why kit lenses—the lenses that are sold in a set with new cameras—are usually zoom lenses.

Telephoto lenses let you fill the frame with a subject and create a creamy background blur, all with little distortion. Read on to learn more about them. (Reported by Tomoko Suzuki)

From close-ups of insects to stunning waterfalls and the sparkling Milky Way, the tiny and versatile RF24mm f/1.8 Macro IS STM is a great companion for exploring the outdoors.

For example, the RF24-105mm f/4-7.1 IS STM has a focal range of 24-105mm.  Its widest angle of view is at its 24mm “wide end”, and it zooms in to 105mm—the “tele” or “long” end.

The objective lens is the primary magnifying element in optical instruments. Positioned closer to the object being observed, it captures and magnifies the incoming light, bringing the specimen into focus. The objective lens is characterized by its varying magnification levels and includes the numerical aperture of the objective.

Our photographer fell in love with the excellent image quality and beautiful, creamy bokeh on this lens. See it for yourself.

Canon’s new RF85mm f/1.2L USM DS features the new Defocus Smoothing coating, which promises smoother, softer bokeh. Read on to find out more.

The EOS R system is Canon’s next evolution of EOS. At the heart of the EOS R system lies the 54mm large diameter RF mount. This revolutionary RF mount promises higher image quality – wider lens elements can be placed closer to the sensor, thus, reducing light refraction and aberrations.

Conversely, the ocular lens, also known as the eyepiece, is situated near the observer's eye. Its primary function is to further magnify the image produced by the objective lens. Ocular lenses are often interchangeable, allowing users to customize their viewing experience based on desired magnification. The most common magnification for a microscope ocular lens is 10x. Additional magnifications of microscope ocular lenses include 12.5x, 15x, and 20x.

There are four types of zoom lenses. Wide-angle zoom lenses enable you to capture a wide area of the scene. Standard zoom lenses and superzoom lenses cover a wide range of focal lengths including telephoto ranges. Meanwhile, telephoto zoom lenses enable you to capture close-up images of faraway subjects.

Fast, ultra-wide-angle, and compact, the RF16mm f/2.8 STM is a great option for walkarounds, vlogging, and even close-ups of nature.

The new RF50mm f/1.2L USM is a standard prime lens that is capable of handling subjects in a wide variety of genres from portrait to street photography.

Another way of categorising zoom lenses is by their maximum aperture, which is indicated in the lens name. If the maximum aperture changes as you zoom in, it’s a variable aperture zoom lens. If it stays the same throughout, it’s a constant aperture zoom lens.

The shrinking maximum aperture on variable aperture zoom lenses means less intense background bokeh at longer focal lengths compared to a constant aperture zoom lens.

The new RF600mm f/11 IS STM and RF800mm f/11 IS STM are set to make super telephoto photography more accessible than ever.

How wide or zoomed in a zoom lens can go is reflected in the lens name and on the lens body. It is expressed in terms of focal lengths.

The objective lens and ocular lens are indispensable components in optical instruments, each contributing uniquely to the observation process. Recognizing their differences and understanding how they collaborate enhances our ability to explore the microscopic world with precision and clarity.

The RF14-35mm f/4L IS USM is Canon’s latest ultra-wide-angle zoom lens for the EOS R system, and it promises excellent portability even with its wider 14mm wide-angle end, together with the traditional L series image quality.

Constant aperture zoom lenses are appealing because they allow the same amount of light to enter the lens even at longer focal lengths. However, they tend to be larger, heavier, and more expensive than similar variable aperture zoom lenses due to their more complex design.

As the diagram shows, maximum aperture aside, a 24-105mm standard zoom lens covers the same focal range as at least 6 different prime lenses.

Which recording resolution should you select, and why does it matter? Read on to find out why they exist and what they are for.

The RF24-105mm f/4-7.1 IS STM is a variable aperture zoom lens—you can tell because its aperture is stated as a range. It’s lighter and more portable than its constant aperture counterpart, the RF24-105mm f/4L IS USM, but the latter offers more flexibility.

What do you do when you see an interesting building from afar and want to frame it in different ways? Moving closer to the building might not be physically possible, and even if it were, you’d get a very different point of view standing right under it. A zoom lens helps you get wide shots and close ups from the same spot just by turning the zoom ring.

When using a lens on an APS-C sensor, the 1.6x crop factor applies. For example, the RF-S18-45mm f/4.5-6.3 IS STM, a popular kit lens for APS-C EOS R series cameras, achieves a field of view equivalent to approximately 29 to 72mm on a full-frame camera.

Compares the RF50mm f/1.8 STM and EF50mm f/1.8 STM in terms of its external design, resolving power, bokeh quality, backlight performance, real world image stabilisation effect, and operability.

To achieve optimal magnification and clarity, the objective lens and ocular lens must work in harmony. The process begins with the objective lens capturing light from the specimen, forming an intermediate image. This image is then further magnified by the ocular lens, delivering a detailed and enlarged view to the observer.

The RF24-105mm f/2.8L IS USM Z is the perfect lens for both photography and videography with its focal length and large aperture.
