What Does Eos Mean Canon

What Does Eos Mean Canon – 2018 has been a big year for mirrorless cameras with Nikon, Canon and Panasonic all announcing their first full-frame mirrorless systems. Nikon was first to strike when it released the Nikon Z-series cameras in the summer, but Canon wasn’t far behind when it introduced the EOS R a couple of months later. Over the years, Canon has built a reputation as a company that likes to sit on their eggshells a little too long, and it can certainly be argued that their first entry into the full-frame mirrorless market is relatively late. After all, it usually takes two or three generations of cameras to finally get things right and with other camera companies like Sony, Fuji, Olympus, Panasonic and Leica already having years of experience in mirrorless technology, Canon doesn’t have the privilege of an Advantage.

Therefore, it was crucial for them not only to develop a reliable and ready-to-use camera system from the outset, but also to enable full compatibility of existing EF mount lenses without serious drawbacks and limitations. With the EOS R, Canon has avoided the trend of introducing separate pro and entry-level bodies (such as the Sony A7/A7R or Nikon Z6/Z7) and instead opted to use a single entry-level full-frame model.

The EOS R is based on the familiar 30.3 megapixel full-frame CMOS sensor it shares with the Canon EOS 5D Mark IV DSLR. The sensor is integrated with Canon’s impressive Dual Pixel CMOS AF system, which has a whopping 5655 selectable focus points covering 88% of the frame horizontally and 100% vertically. In particular, the focus is said to work down to -6EV when used with an f/1.2 lens and -3EV with an f/2.8 lens. The camera also has 5fps burst shooting with continuous AF, a 3.69 million-dot electronic viewfinder with 0.76x magnification along with a 3.15-inch fully articulating touchscreen, an SD card slot, and 4K video with 10-bit output externally via HDMI.

With mirrorless technology being the future, it was crucial for Canon to devote sufficient time and resources to building a highly desirable and future-proof camera system that will one day replace EOS DSLRs. Canon has always understood that high performance lenses must accompany a powerful camera system and has invested a lot of resources in the design of the new RF lens mount. With a large internal diameter of 54mm and a short flange back distance of just 20mm, the new RF mount allows Canon engineers to build optics with larger rear elements and better performance than their EF counterparts, such as the exceptional RF 50MM F/1.2L USM. Canon is clearly placing a lot of emphasis on building a strong ecosystem of lenses, with four RF lenses already released and six more on the way in 2019.

With only a handful of RF lenses available at launch, it was imperative for Canon to find a way to complement existing EF lens kits alongside their first full-frame mirrorless camera. Using a mount adapter was the obvious choice, as it allowed Canon to design an entirely new and more cost-effective RF lens mount while retaining full functionality with existing EF lenses.

Unsurprisingly, when the Canon EOS R was first launched, the first accessory available was the Canon Mount Adapter EF-EOS R. The Canon Mount Adapter EF-EOS R is a simple adapter that allows you to use all Canon EF, EF-S models and TS-E lenses on RF mount cameras. It provides full autofocus and autoexposure support along with a weatherproof design. The second adapter is the Control Ring Mount Adapter EF-EOS R which offers similar functionality to the EF-EOS R, but adds a lens control ring. Finally, there are the EF-EOS R Drop-In Filter Adapters which eliminate the need to mount an ND or polarizing filter to the front of the adapter-mounted lens. This makes it especially useful for using wide-angle EF lenses that traditionally don’t accept filters due to their bulbous front elements.

On paper, the EOS R looks like a mirrorless version of the Canon EOS 5D Mark IV and the two cameras have some similarities, but there are also some key differences between the two. The most obvious difference is in their unique core technologies: the Canon EOS R is a mirrorless camera that feeds the image directly from the image sensor into an electronic viewfinder (EVF), while the Canon 5D Mark IV is a DSLR camera that reflects the image . through a pentaprism to an optical viewfinder (OVF). Not only does this affect the overall size and weight, with the 5D Mark IV being both bigger and heavier, but it also completely changes how the two operate in the field.

A second notable difference is that the two cameras have completely different mounts. The EOS R has the new Canon RF mount, while the 5D Mark IV has the older Canon EF mount. This has a big effect on which lenses you can use with the two cameras. The EOS 5D Mark IV is based on a large selection of Canon EF lenses, while the EOS R can only fit new Canon RF lenses, currently limited to a total of four (Canon RF 24-105mm f/4L USM IS, Canon 28 -70mm f/2L USM, Canon 35mm f/1.8 IS Macro and Canon RF 50mm f/1.2L) and six lenses due for release in 2019. To use EF mount lenses on the EOS R, you need to use the Adapter for Canon EF-EOS R mount which allows all Canon EF, EF-S and TS-E lenses to be used on RF mount cameras.

Thirdly, the mirrorless design and electronic viewfinder have the distinct advantage of showing you a live feed of exposure and camera settings at all times. This “what you see is what you get” approach allows for far greater control over exposure and the final image. For this reason, the EOS R offers several distinct advantages over the 5D Mark IV for landscape, travel, interior and street photography.

On the other hand, there are some serious drawbacks to this design that mainly affect the EOS R’s performance for sports and action photography. The EVF suffers from a small lag in the video feed when a picture is taken, and this greatly hampers your ability to track a fast-paced subject as it moves across the frame. In terms of autofocus characteristics, the EOS R’s Dual Pixel CMOS AF system, featuring 5655 AF points covering 88% of the frame horizontally and 100% vertically, allows for a much greater reach on the subject. whole frame compared to the 5D Mark IV whose AF points. they are mostly clustered around the center of the frame.

The extreme coverage makes focusing techniques such as back button focusing on the EOS R almost redundant and allows for greater compositional freedom. However, when it comes to which camera can consistently track a moving subject across the frame, the nod goes to the 5D Mark IV whose excellent autofocus system is better at keeping up with erratic subjects. .

The 5D Mark IV’s advantage for sports photography also extends to its 7fps burst rate, which, while not groundbreaking, is still better than the EOS R’s 5fps (without live view) and 3fps (with live view). The advantage of the EOS R is a deeper buffer depth of over 60 RAW images with a UHS-II SD card compared to just 21 images on the 5D Mark IV with a CF card. Overall, the 5D Mark IV’s optical viewfinder/AF system is more effective than the EOS R’s EVF/Dual Pixel CMOS AF combination for sports and action photography.

Fourth, the two cameras have different controls and ergonomics. The 5D Mark IV takes full advantage of its larger size and traditional controls to deliver a nearly seamless handling experience. Comparatively, the EOS R features an experimental control layout with no mode dial, but rather a mode button on the right side. It also forgoes the dedicated AF joystick and Canon rear stick.

The EOS R does, however, have the multifunction touch bar. It’s an innovative button that offers a high degree of customization, but a fiddly one that feels awkward to use. Overall, the EOS R is much less intuitive to use than the 5D Mark IV. The 5D Mark IV also benefits from two card slots, longer battery life (even though the two share the same battery), and sturdier weather protection.

Fifthly, the EOS R has improved video specs over the 5D Mark IV, with a more efficient codec, C-log recording options and the option to export 10-bit log footage to an external recorder via HDMI. The EOS R also has a fully articulating flip-up screen while the 5D IV’s screen is fixed in place.

Comparing the Sony A7 III, now in its third generation, to the EOS R is a relatively one-sided affair, as Sony has had plenty of time to perfect the A7 III and we recently ranked it the best mirrorless camera on the market.
