Polarisation meaning in Physics

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.

A unique lens that combines an ultra-wide-angle focal length with a compact, lightweight body, the RF16mm f/2.8 STM promises to inspire new perspectives.

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.

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.

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.

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.

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.

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.

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.

With up to 8 stops of image stabilisation through Coordinated Control IS, be amazed by what you can shoot handheld on this fast medium telephoto prime lens.

Increasing your lens collection to cover more focal lengths? Consider the compact RF70-200mm f/4L IS USM telephoto zoom lens, which will bring you one step closer to owning a zoom lens trinity.

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.

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.

Circularpolarization

Canon’s RF800mm f/5.6L IS USM and RF1200mm f/8L IS USM pack professional grade optics and build into smaller, more portable bodies, offering ultra-long reach with unprecedented mobility.

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.

Zoom from 200mm to 800mm with the RF200-800mm f/6.3-9 IS USM, which provides an unprecedented focal range in one compact, lightweight body.

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.

What is polarization ofwaves in Physics

As you zoom in, the shrinking maximum aperture reduces light entering the lens. You will have to use a slower shutter speed and/or higher ISO speed to maintain the same brightness. The bokeh intensity also changes.

Want to try something with more reach than what your standard zoom kit lens can provide? Consider the RF100-400mm f/5.6-8 IS USM, which is around the size of a typical 350ml tumbler.

Light waves are transverse: that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. A beam of unpolarized light consists of waves moving in the same direction with their electric vectors pointed in random orientations about the axis of propagation. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In circular polarization the electric vector rotates about the direction of propagation as the wave progresses. Light may be polarized by reflection or by passing it through filters, such as certain crystals, that transmit vibration in one plane but not in others.

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.
