Sigma Might Make An Important Canon RF Mount Related Announcement Soon

Canon Rf Mount

Sigma might be set to soon announce something important about Canon RF mount lenses (i.e. for the Canon EOS R system).

A new rumor suggests, coming from various sources, that Sigma will soon announce their long term plans concerning RF mount lenses. Moreover, it seems that the development and upcoming release of the Canon EOS R5 might have sped up Sigma’s plans to have RF mount lenses available by 2021.

The interesting part in the rumor is that Sigma will not convert existing ART lineup lenses to the RF mount but come up with an exclusive RF mount lens lineup. And that, in our opinion, is very interesting.

Let’s hope Sigma really comes up with an exciting RF mount lens lineup but we recommend you take this rumor with a grain of salt for the time being.

More RF mount information is listed here.

More to come, stay tuned.

Canon Speedlite 600EX II-RT Replacement Might Be Announced Soon, Report

Canon Speedlite 600EX II-RT

Canon might soon announce a replacement for the Speedlite 600EX II-RT, a new rumor suggests.

Since the Speedlite 600EX II-RT saw a price drop in January, the possibility of a replacement was on the table. Apparently the replacement has been delayed along with both the Canon EOS R5 and Canon EOS R6, and should be announced together with the R5 and R6 in the next months.

While there are no rumored specifications, the source of the rumor states that the upcoming Speedlite will be a “big step forward”.

Stay safe, stay tuned.

Above: There Are No Bad Cameras, Only Bad Photographers – And Some Other Harsh Camera Truths – Robin Wong

There have been a lot of complains about how recent camera releases are not good enough and some even claimed a camera being “dead on arrival”. The chase for camera perfection is getting out of hand and honestly, quite pointless. The camera is just a tool, and seriously, the cameras we have today are so much more powerful and capable than any other cameras released more than 10 years ago. We should shift our focus away from demanding more and more and more and truly look into ourselves and ask ourselves – why are we not happy with our own photographs? Is the camera truly to be blamed?


HDR PQ HEIF: Breaking Through the Limits of JPEG – Canon Singapore

As Canon’s latest flagship professional DSLR camera, the EOS-1D X Mark III boasts amazing continuous shooting speeds and support for 5.5K RAW movie recording, but let’s not ignore its various improved still shooting features. In this article, we take a closer look at its support for the HDR PQ HEIF format, which takes still image shooting to a whole new frontier.


Gear that changed my (photographic) life: the Canon PowerShot G3 – DPReview

It’s hard to believe that the Canon G-series is almost 17 years old, and while technology has certainly marched forward, ‘G cameras’ have consistently been a favorite of enthusiasts and even pros.


The gear that changed my (photographic) life: the Canon EOS 10D – DPReview

The 10D was a substantially new camera compared to the models that preceded it, and it replaced the D60 with an almost indecent haste (the D60 had been on the market for little more than a year before the 10D came along). Compared to the plastic-bodied D30/D60 it was better built, featured a far superior rear LCD (with a usable magnification feature) offered a more rounded styling, closer in spirit to the EOS-1D series, and was much quicker in operation.


8K and then some: what the Canon EOS R5’s video specs mean – DPReview

Canon kickstarted the success of the stills/video hybrid ILC with the introduction of the EOS 5D Mark II in 2008. Since then it appears to have focused most of its video efforts on its Cinema EOS line of professional video cameras.

However, as part of its drip-feed of EOS R5 specs, Canon has spelled out a lot more about its video capabilities. And, from what’s been said, it looks like the biggest leap forward in video for Canon’s main EOS line since that launch 12 years ago.

We already knew that the EOS R5 was going to be able to shoot at 12 fps with its mechanical shutter and 20 in e-shutter mode and that it was going to shoot 8K, but the more detailed video specs are worth digesting…


Canon’s change of direction – News Shooter

It wasn’t that long ago where we were wondering what Canon was doing. While their competition was releasing new and innovative products, Canon seemed to be content to move along at its own pace. Well, how times have changed.

The ‘new’ Canon is now bold, innovative, and releasing products that are once again exciting the filmmaking community. With the release of the C500 Mark II, today’s announcement of the C300 Mark III, and the EOS R5’s specifications coming to light, Canon now seems to be firmly back on track.


Unboxing the new Canon EOS-1DX Mark III – Photofocus

I opened the shipping box only to find another box inside. The fine print on the white box’s label revealed that it was from Canon. I found that this box held even more boxes. Inside was the EOS-1DX Mark III box, a SanDisk CFexpress 64GB card box and another one with a CFexpress card reader.


EPFL & Canon Work Towards 2.2µm-small SPAD Pixels – Image Sensors World

It’s something I’d been dreaming of for a long time,” says Edoardo Charbon, an EPFL professor and head of the Advanced Quantum Architecture Laboratory in EPFL’s School of Engineering. “MegaX is the culmination of over 15 years of research on single photon avalanche diodes (SPADs), which are photodetectors used in next-generation image-sensor technology.

A similar paper has been posted in Arxiv.org a couple of months ago.


Canon EOS RP Review Conclusion: The affordable Canon RP brings full-frame fun to a wider audience – Imaging Resource

While it’s not the newest camera under the sun, the compact Canon RP is an important camera, particularly given its price point for as a full-frame camera. The little Canon EOS RP is, at this point in time, Canon’s second full-frame mirrorless camera, coming after the mid-range EOS R.


How 1987 Led to Canon’s Domination of Photography – Fstoppers

Perhaps the single biggest seismic shift in the camera market took place in 1987 with the announcement of Canon’s EOS (Electro-Optical System), crucially unleashing the EF lens mount, which removed all mechanical linkages, introducing significant improvements to autofocus. It additionally incorporated the largest throat diameter of any SLR of the time, which enabled Canon to produce the fastest SLR lens in the shape of the EF 50mm f/1.0! However, the EF mount broke compatibility with the previous FD mount, requiring users to use mount converters or upgrade their lenses.
