EF lenses are produced for Canon’s full-frame DSLRs. EF-S lenses are produced for Canon’s APS-C DSLRs. While there is a wide range of EF lenses, many of them are designed with advanced amateurs and professionals in mind. EF-S lenses, on the other hand, are designed to take advantage of the smaller APS-C sensor size.
Hereof, What does RF mean Canon? At the heart of Canon’s EOS R full frame mirrorless system is the RF lens mount. RF lenses use the same optimised 54mm inner diameter as Canon’s EF lens range but the flange distance (the distance between the lens mount and the camera sensor) has been reduced by more than half to just 20mm.
What does EF-M stand for? EF-M – a new lens format specifically designed for the Canon EOS M mirrorless camera system with EF-M mount. Just like the EF-S lenses, EF-M are designed for APS-C sensor cameras. They will only fit Canon EOS M cameras, though, thanks to shorter flange focal distance (distance between lens mount and film/sensor plane).
Accordingly, What does EF-M stand for Canon? Canon calls this the Canon Mount Adapter EF-EOS M. EF means “electronic focus,” meaning that there is an autofocus motor in the lens itself. All Canon lenses since 1987 have been EF. These are the lenses which attach to the front. EOS-M means that it adapts these lenses to an EOS-M camera attached to the back.

What is the difference between EF and PL mount?
The PL mount is built to accommodate that. It grips the lens firmly with a four-point friction lock instead of the EF mount’s leaf-spring bayonet, which is both more secure and more precise. A heavy cine-zoom lens is much more likely to shift slightly on an EF mount than a PL.
Are Canon RF lenses worth it?
Are RF lenses better than EF? Paired with a Canon EOS R5 camera, I also found the RF lens to be markedly better at face and eye tracking than the EF. Those improvements do come at a cost, though. Unlike the EF version, the RF 24-70 is entirely focus by wire, meaning the focus ring has no mechanical control over the lens.
What does EOS mean Canon? EOS stands fo Electro-Optical System. But like the other “names” is just a brand name by Canon. Powershot means nothing in itself but generally it is Canon’s line of P&S cameras. Numbers in the name just signify a difference in features and newer models.
What is the difference between EF and RF lens?
The RF version is also slightly sharper wide open, but not significantly, and still less sharp than the slightly slower EF Sigma 50mm f/1.4. In short, the differences are there if you’re looking for them, but they’re not as immediately noticeable as the differences between the RF and EF versions of the 24-70 or 70-200.
What does USM mean on Canon lenses? It’s easy to take the technology behind autofocus for granted. Find out about the history of Canon’s Ultra Sonic Motor (USM) and STM technologies and how they deliver fast, smooth and quiet AF capabilities.
Is EOS-M the same as EF-M?
The Canon EF-M lens mount, introduced in 2012, is a derivative of the Canon EF lens mount designed for use with the Canon EOS M mirrorless interchangeable-lens camera. The EF-M lens mount is one of Canon’s two new systems for mirrorless cameras, the other being the RF mount.
What is EF-M and EF-S lens? Put simply, Canon EF-S lenses are designed solely for use on Canon APS-C DSLRs. Canon EF lenses are designed to work with full frame and APS-C DSLRs from Canon. Canon EF-S lenses have a smaller image circle that is only big enough to cover the smaller sensor found on Canon APS-C cameras.
What’s the difference between EF and EF-M?
The difference is in the flange focal distance, i.e. the distance between the mounting flange for the lens and the film/sensor. Canon’s EF-M has an 18mm flange focal distance, compared to 44mm for the EF and EF-S systems.
What camera has PL mount?
Arri PL is a lens mount developed by Arri for use with both 16 mm and 35 mm movie cameras. The PL stands for “positive lock”. It is the successor mount to the Arri bayonet; unlike the bayonet mount, however, it is incompatible with older Arri-mount lenses, due to the larger diameter.
Which lens mount is best? Bayonet mounts are the most favored of these three mounting types, due to the ease and speed of installing and removing lenses from camera bodies, the ability to incorporate electronic contacts using this attachment method, and the repeatable precision afforded by a simpler design.
Can you mount PL lenses on EF? The Fotodiox Pro Lens Mount Adapter ARRI PL to Canon EF allows you to use select ARRI PL-mounted lenses to fit on a camera body with a Canon EF mount, allowing you to use your existing PL mount lenses with newer cameras that feature the Canon EF mount.
What is the difference between AF and EF lenses?
Why are RF lenses so expensive? 1 — They are new and therefore in short supply. 2 — there are a lot of r&d costs which have to be recouped and the market for RF lenses is currently smaller than the market for EF lenses. This means each lens sold has to pay back a larger share of the r&d costs.
Why are Canon RF lenses so big?
The RF mount’s large diameter allows wider lens elements to be placed closer to the sensor, reducing the need to bend the light rays as smaller-diameter lens mounts do: The larger-diameter Canon RF lens mount.
Why are Canon RF lenses out of stock? Canon today released a list of RF lenses that will be hard to come by due to shortages. Since Covid-19, manufacturers have been struggling to meet customer demand. Canon has been dealing with serious issues delivering RF lenses to market in a timely manner.
What does RF mount stand for?
2018: RF Mount (R Focus) was introduced with the EOS R, Canon’s first MILC (Mirrorless Inter-Changeable Lens) Camera.
