A new optical formula patent for a wide angle RF mount zoom has appeared. This one shows the formula for a couple of Canon RF 17-35mm f/4-5.6 designs.

The lenses in the two embodiments aren’t all that much smaller than an EF counterpart, and it looks like zooming is slightly external.

Canon RF 17-35mm f/4-5.6

• Focal length: 17.50mm 27.00mm 33.95mm
• F-number: 4.00 5.03 5.80
• Half field angle: 51.03° 38.71° 32.51°
• Image height: 21.64mm 21.64mm 21.64mm
• Lens total length: 121.00mm 118.39mm 121.18mm
• BF: 20.00mm 30.99mm 38.92mm

Canon RF 17-35mm f/4-5.6

• Focal length: 17.50mm 27.00mm 33.95mm
• F-number: 3.94 4.92 5.69
• Half angle of view: 51.03° 38.71° 32.51°
• Image height: 21.64mm 21.64mm 21.64mm
• Total lens length: 122.00mm 119.11mm 121.87mm
• BF: 20.00mm 31.62mm 40.07mm

Once all of the fast zooms ship this year, I think it’s safe to assume we’re going to see f/4 variants soon after.

Flat-Field Correction

You can now reduce shading, or lens cast, from your digital photos using the Flat-Field Correction feature. Shading can occur from a variety of different lenses and can result in both asymmetrical vignettes as well as color casts introduced by certain lens characteristics.

Flat-Field Correction is available in the Library module. To apply the correction, select all your photos in a natural interleaved order and choose Lightroom > Library > Flat-Field Correction.

For detailed information, see Flat-Field Correction.

Press Release:

Profoto, May 15, 2019: We are never fully satisfied with the products we make. We always strive to take steps forward, whether they be baby-steps or strides. That is why we not only will create ground-breaking products. But we’ll also continually evaluate and improve those products. Like we have done with the launch of Profoto A1X, the A1’s new and improved sibling. It has a little more of everything that made its predecessor a success. An even more powerful battery, faster recycling and Sony compatibility are some of the 30 and more updates that we have made to the product. Or put in other words – more when it matters.

Is this the next evolution of the Canon EF 200-400mm f/4L IS USM 1.4x? Here is a patent showing a dual teleconverter Canon telephoto prime, an EF 400mm f/5.6.

What’s cool about the dual teleconverters, is one is a focal length reducer, so you get the EF 400mm f/5.6 and the built-in focal length reducer converter brings the lens to an EF 300mm f/4, or at the other end, a 560mm f/8 lens.

There has long been a desire for a replacement to the classic Canon EF 400mm f/5.6L, even if Canon just added image stabilization, but this is definitely a unique direction to take the lens on Canon’s part.

Not much has happened with the EOS M camera lineup since the very successful EOS M50 launched back in February of 2018. The advent of the EOS R system has put a certain cloud over the future of the EOS M system, but Canon executives continue to say they will invest in the system in the future, though they’ve never really committed to how long into the future we’ll see new EOS M products.

We’re told that the EOS M camera lineup will be addressed in late August with a replacement for at least the EOS M5 and that the EOS M6 isn’t going to see a direct replacement. The source suggested the EOS M lineup will consist of 3 camera bodies in 2020, an EOS M500, EOS M50 and EOS M5 Mark II.

The same source said 2 new EF-M lenses will arrive alongside the new camera body, though what those lenses are was unknown.

This is [CR1], so take it with the needed grain of salt.

Last month we posted that a 32.5mp APS-C sensor was on the way and it looks likes that information has been confirmed through a Taiwanese certification agency.

Code Names K437 & DS126801 APS-C DSLR:

• Digital SLR
• Wifi and Bluetooth 4.1
• LP-E6N battery
• 6 level battery display, similar to the EOS 5D Mark IV
• Maximum image size: 6960 × 4640, 32MP
• This will likely be a 2019 release

We’d wager that this camera will be the replacement for the EOS 80D and potentially the EOS 7D Mark II.

Press Release:

Since the announcement of the Canon EOS R last year, there have been unrelenting questions about what a true next-generation professional mirrorless camera from Canon was coming.

We’re told that there are two bodies planned that will be marketed as “professional” bodies when they hit the market in 2020. However, neither one of them will be considered equals or a replacement for the EOS-1D series of DSLRs. We’re going to see an EOS-1D X Mark III next year and that will be the flagship camera from Canon through 2020.

The obvious first EOS R series camera will be the high-resolution body we’ve been talking about for months.

The other will be a “sports” oriented camera, with higher frame rates, lower resolution and some advancements in sensor performance. This camera will be designed for prosumer shooters as well as an ideal 2nd body to “professional” photographers that may be using the EOS-1D series of DSLRs. So it almost sounds like a mirrorless full-frame EOS 7D body.

We’re told that there is a general feeling professional sports shooters (and other professional EOS-1D shooters) will be the last to embrace mirrorless cameras across the board, and we agree with that. So making a complimentary camera body to the EOS-1D series that checks a lot of the boxes would make sense.

The same source says there has been no mention or talk about what sort of advancements in video are coming for the EOS R line.

More to come…

The Canon RF 85mm f/1.2L USM development was announced back in February along with 5 other lenses, including a second 85mm f/1.2L lens with defocus smoothing, the Canon RF 85mm f/1.2L DS USM.

We expect the Canon RF 85mm f/1.2L USM to be officially announced on or around May 9, 2019, and it will be available for preorder on that day.

A monitor calibration tool is something I’ve always recommended to photographers, from hobbyists to professionals. I’ve always been a bit taken aback by how many photographers I’ve run into over the years that don’t utilize a relatively inexpensive tool to get the most out of their monitors.

Full disclosure: Datacolor sent me a SpyderX Elite for free and they have been an active sponsor of Canon Rumors over the years.

Fuller disclosure: I am not a reviewer at the best of times, so this is an honest review of the feature(s) I use, and does not discuss every single feature available to you. I am not an expert on color science or printing. However, I do have eyes and matching my editing to third-party printing is very important to me.

I have been using Datacolor calibrators since the Spyder2 and I have always been impressed by their software and the performance of the calibration tools. I have always purchased or accepted each new version since the Spyder2.
