Create lighting effects you've always dreamed of. The Optical Spot is a unique lighting tool that allows you to achieve a range of lighting effects that were never possible before. Whether you're aiming for a modern, eye-catching light pattern on your subject or a subtle texture on your background, the Optical Spot will give you what you need.
The Westcott Optical Spot and included accessories, designed by Lindsay Adler, are ideal for creating selective lighting, dramatic special effects, subtle textures, and creative patterns on any subject, surface, or background with precise focusing and control.
The included high-quality 150mm f/3.5 EF lens projects a sharp-edged circle of light without discoloration or halo effect that can be focused or defocused for complete control. The Optical Spot includes four built-in adjustable metal leaves for creating precise shapes and slices of light on your subject or background.
Create subtle or dramatic effects with the 8 gobo designs that project focusable images or patterns of light onto a surface or subject. Combine with a gel filter for adding color to your scene or model. Extension packs are available with a variety of gobos patterns and color gels options.
As with the EOS 2000D that we recently reviewed, the new Canon 4000D is heavily based upon the previous EOS 1300D model. There are also a few key differences between the EOS 4000D and the slightly more expensive 2000D - 18 versus 24 megapixels, a plastic lens mount versus metal, just wi-fi connectivity versus Wi-fi and NFC, a manual pop-up flash versus an automatic one, and a lower-resolution, smaller 6.8cm screen versus a a higher-resolution, larger 7.5cm LCD - but otherwise there's very little to tell them apart.
The only real ways to tell the EOS 4000D apart from the 2000D are the plastic lens mount and the blank, non-printed buttons. Although we kind of hate the idea of a plastic lens mount, out of the two cameras we'd probably pick the EOS 4000D and save a few pounds/dollars to spend on a nice camera bag or towards a second lens. The durability of the lens mount is much less of an issue if you're not actually changing lenses that often, which probably applies to most would-be buyers. Turning to the buttons, the EOS 4000D has all of the graphics printed on the camera body itself, rather than actually on each individual control, presumably to cut costs during manufacturing - you probably wouldn't even notice the difference if you looked at the cameras side by side.
When it comes to shooting, the Canon EOS 4000D will switch on and fire a shot in around 0.7 seconds, although it takes a second or so longer for the LCD screen to display anything. Focusing speed is largely dependent on your choice of lens. Our 4000D test sample came paired with the EF-S 18-55mm III kit lens, which is a competent enough performer, but crucially doesn't offer built-in image stabilisation, unlike the EOS 2000D's kit lens.
The EOS 4000D is Canon's cheapest ever DSLR and is clearly aimed at students on a budget and photography beginners interested in buying their first interchangeable lens camera without having to break the bank.
Compared to the EOS 2000D that was announced at the same time as the 4000D, and to the older EOS 1300D, as you'd expect this cheaper model has made a few concessions to hit the lower price point, most notably the very poor quality LCD screen and non-stabilised kit lens. Some of the other key differences, such as the lighter plastic body, non-printed buttons, plastic lens mount and the manually activated flash are much easier to live with, as is the 18 megapixel rather than 24 megapixel sensor.
In summary, the whole point of the new Canon EOS 4000D is to make DSLR photography available to a wider audience thanks to its out-right affordability, and in that regard it largely succeeds. If you're looking for your first interchangeable lens camera but thought that a DSLR was out of reach, the Canon EOS 4000D may make you think again...

The Canon EOS 2000D and EOS 4000D are new entry-level DSLR cameras. Both cameras offer APS-C sensors, DIGIC 4+ image processors, seamless Wi-Fi connectivity, 3fps continuous shooting, straightforward in-camera feature guides, wi-fi connectivity, 500 picture battery life and Full HD movie recording. The EOS 2000D (Rebel T7) additionally features a new 24.1 megapixel APS-C sensor, 7.5 cm LCD screen, Near Field Communication (NFC) and a metal lens mount, while the EOS 4000D (Rebel T100) has an 18 megapixel APS-C sensor, 6.8 cm LCD screen and a plastic lens mount.
Both models include simple in-camera feature guides, perfect for those looking to improve their storytelling potential as they upgrade from a smartphone. Both cameras include six image settings outside of basic auto modes and a variety of creative filters, enabling experimentation with manual control and the artistic freedom to tell dynamic and vibrant stories. Those embarking on their first DSLR adventure will also benefit from the Canon Photo Companion app, which provides the necessary tips on getting the best out of the cameras.
Both DSLR models are compatible with over 80 Canon EF and EF-S lenses and range of accessories, giving beginners the greatest choice of systems as they grow and develop their photography skills. The new cameras will be sold as a body only option or with a selection of lens kit options, including an 18-55mm f/3.5-5.6 IS II lens.
The EOS 2000D and 4000D are very similar, very cheap DSLR cameras aimed at new photographers. There are a few key differences that differentiate them - 24 versus 18 megapixels, metal lens mount versus plastic, NFC connectivity versus just Wi-fi, automatic pop-up flash versus manual, and a 7.5cm LCD versus 6.8cm - but otherwise there's very little difference between them. They both use the venerable Digic 4 processor, which first made its debut back in 2014, and the 4000D has a sensor that purportedly dates back to 2009...
The Canon 2000D and 4000D are very much built to a sub-400 price point. With fixed LCD screens, small optical viewfinders, and plastic bodies, they're hardly at the cutting edge of design. What they might lack in looks, though, they make up for in familiarity, as they inherit key EOS traits such as the logical menu system, a control layout that provides more direct control over the camera's key settings than the more expensive EOS M50 mirrorless camera that was also launched today, a proper flash hotshoe and a built-in pop-up flash, shooting mode dial and control dial on the top, and of course full support for Canon's vast range of EF lenses (although we'd hesitate to use the longer, heavier optics on the plastic-mounted 4000D).
Sunglasses or sun glasses (informally called shades or sunnies; more names below) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. In the early 20th century, they were also known as sun cheaters (cheaters then being an American slang term for glasses).[1]
Since prehistoric times until the spread of contemporary UV-shielding spectacles against snowblindness, Inuit made and wore Snow goggles of flattened walrus or caribou ivory with narrow slits to look through to block almost all of the harmful reflected rays of the sun.[4][5] In many different forms and with many different materials, the indigenous peoples of North America and northern Asia crafted highly efficient equipment to protect their eyes against the damaging effects of strong sunlight in icy circumstances.[6]
James Ayscough began experimenting with tinted lenses in spectacles in the mid-18th century, around 1752. These were not "sunglasses" as that term is now used; Ayscough believed that blue- or green-tinted glass could correct for specific vision impairments. Protection from the Sun's rays was not a concern for him.
In 1913, Crookes lenses[17] were introduced,[18] made from glass containing cerium, which completely blocked ultraviolet light.[19][20] In the early 1920s, the use of sunglasses started to become more widespread, especially among movie stars. Inexpensive mass-produced sunglasses made from celluloid were first produced by Sam Foster in 1929. Foster found a ready market on the beaches of Atlantic City, New Jersey where he began selling sunglasses under the name Foster Grant from a Woolworth on the Boardwalk.[21] By 1938, Life magazine wrote of how sunglasses were a "new fad for wear on city streets ... a favorite affectation of thousands of women all over the U.S." It stated that 20 million sunglasses were sold in the United States in 1937 but estimated that only about 25% of American wearers needed them to protect their eyes.[2] At the same time, sunglasses started to be used as aids for pilots and even produced for the gaining aviation sector, eventually adding to sunglasses as cultural icons and to their popularity. Polarized sunglasses first became available in 1936 when Edwin H. Land began experimenting with making lenses with his patented Polaroid filter. In 1947, the Armorlite Company began producing lenses with CR-39 resin.[22] 2ff7e9595c
