Canon has released a 0.71x EF to RF speed booster adapter

by 3 Comments

Canon has announced a new EF to RF 0.71x speed booster adapter. Like the speed boosters from Metabones and similar items from Viltrox and others, it allows you to use lenses designed for a larger sensor on a camera with a smaller sensor while retaining a wider field of view and, as the name suggests, effectively increasing the light transmission.

The release coincides with the launch of the new Canon EOS C70 cinema camera, but could it add more fuel to the rumours that Canon is planning to ditch the EOS M camera system in favour of APS-C EOS R RF mount cameras?

Metabones has released a Canon EF to RF speed booster to reduce the EOS R 4K crop factor

by 2 Comments

It might seem strange to produce a speed booster that converts full-frame lenses to full-frame. But with the Canon EOS R and EOS RP mirrorless cameras, when you’re shooting 4K video, you’re not exactly using the entire full-frame view of the sensor. The Canon EOS R has about a 1.75x crop factor, and the EOS RP has a 1.64x crop factor (similar to APS-C).

The new Metabones EF-RF Speed Booster ULTRA 0.71x, however, helps to reverse this problem. It widens the view when EF lenses are used on the EOS R and EOS RP to 1.24x and 1.15x respectively when shooting 4K video.

Canon abandons EF mount lenses to focus on mirrorless

by 52 Comments

According to a report on Digital Camera World, Canon will not be releasing anymore EF mount lenses for their DSLRs, despite having just announced the Canon 1DX Mark III, their new flagship DSLR, only yesterday. They say they are open to the possibility of making new ones, though, if the market demands it. But for now, they want to shift their attention towards RF lenses for their EOS R system.

Canon EOS RF/EF hybrid will have a moving sensor to support both flange distances, rumor suggests

by 42 Comments

If the rumors are correct, Canon is working on an EF/RF hybrid EOS mirrorless camera. Now, Canon Watch suggests that this camera will support a moving sensor. And when they say a moving sensor, they mean a sensor that sits on some kind of rails and can move to adjust between different flange distances.

Canon rumoured to be working on an EF/RF hybrid mount mirrorless camera

by 7 Comments

This is the strangest thing I’ve heard in a long time, but according to Canon Rumors, Canon is working on an EF/RF hybrid mount mirrorless camera that doesn’t use any kind of lens adapters. They’ve marked the rumour as a “CR2”, indicating that the information has come from a known reliable source, but I just can’t imagine how this is even possible.

Canon explains why RF mount lenses are better than EF mount ones

by 5 Comments

The pursuit of ultimate optical clarity has been the goal of lens manufacturers for decades. When you look back on the lenses of old, they have vignetting, sharpness issues, weird bokeh, chromatic aberration and all kinds of “problems” (some people refer to this as “character” and is exactly the reason why they like those old lenses).

But Canon’s RF mount takes a step closer to that optical precision that they strive for. In this four-and-a-half-minute video, Canon explains why the RF mount is such a big deal, and what makes it so much better than the EF mount used in their DSLRs.

Yongnuo’s YN450 has a Micro Four Thirds sensor, Canon EF mount, Android OS and shoots 4K video

by 25 Comments

When this camera was first teased last October, my mind was stuck somewhere between “wtf?” and “this is so crazy, it just might work!”. They made the camera sort-off official a few days later by releasing some early specs, which just made me even more confused at this odd combination of tech. Since then, it’s all been a little quiet on the Yongnuo front.

But now, the folks at Cinema5D had the chance to chat with Yongnuo about the new camera during CP+ 2019 and hold one in their hands. It confirms a lot of the specs and answers some questions that had thus far remained unanswered.

New Canon patents hint at lots of long telephoto lenses in the works

by 3 Comments

As well as expanding their EOS R camera and RF mount lens lineups, Canon still seems to be going pretty hard on the long telephoto lenses for the EF mount. Canon News has discovered a number of US patents alluding to what appears to be the recently released 400mm f/2.8L IS III USM, which stole all of Sony’s “Lightweight” thunder, as well as new 300mm f/2.8, 500mm f/4, and 800mm f/5.6 telephoto lenses.

All Canon EF mount lenses may become soft focus lenses with new EOS R adapter

by 8 Comments

A new Canon patent spotted by the folks at Northlight Images shows a design for a new Canon EF to RF mount lens adapter. What’s so special about this one? Well, apparently, the purpose of this one seems to be to turn every Canon EF lens out there into a soft focus lens when used on an EOS R (or other, future RF mount body).

Samyang expands their “XPERT” lens lineup with the XP 35mm f/1.2 for Canon EF

by 1 Comment

While the brands battle it out over who has the largest mount and whose lenses can have the widest apertures, Canon’s DSLRs have proven they have no problem with wide aperture f/1.2 lenses. And Samyang has been adding to that f/1.2 collective again, expanding their “XPERT” line of lenses with another new announcement.

Starting off the XP series with a 24mm f/1.4 and 85mm f/1.2 lenses, they later added a 50mm f/1.2. But this left a rather obvious hole. Now Samyang is filling that hole with the announcement of the Samyang XP 35mm f/1.2 lens for Canon EF.
