EOS Bodies / Patent: 10-22mm f/3.5-4.5 With a Liquid Element
« on: Today at 09:56:31 AM »

A patent showing a 10-22 f/3.5-4.5 optical formula with a liquid element has shown up. I think it’s safe to say that this isn’t going to end up as a consumer product any time soon, but it’s still pretty interesting.

EOS Bodies / Patent: Canon EF 2.0X TC With Diffractive Optics Element
« on: October 19, 2014, 11:07:08 AM »


A patent showing a 2x teleconverter with a diffractive optic element (DO) has surfaced. The 2.0x teleconverter could use a little length reduction, though I’m not sure if DO would reduce the size of the current TC all that much.

« on: October 17, 2014, 02:57:51 PM »

According to Amazon and another local retailer, we should start seeing the Canon EOS 7D Mark II shipping on October 30, 2014. If you select overnight shipping, you should have it for Hallowe’en and that’ll be a great evening to test the ISO abilities of this new APS-C camera.

B&H Photo and Adorama are still showing November for availability.

EOS Bodies / Canon Announces CN20x50 Cine-Servo Ultra Zoom Lens
« on: October 16, 2014, 08:31:45 AM »

Canon introduces new 4K cine-servo, ultra-telephoto lens with world’s longest focal length

United Kingdom, Republic of Ireland, 16 October 2014 – Canon today bolsters its cine servo lens line-up with the new CN20x50 – a high performance, ultra-telephoto zoom lens for sport and nature TV production. Leveraging Canon’s long-standing and unparalleled expertise in lens design, the CN20x50 delivers superb image quality and exceptional creative control, and is the first lens of its type to combine a built-in 1.5x extender, class-leading 20x magnification and a removable servo drive, with a native 50-1000mm focal range that expands to a huge 75-1500mm.

Designed to be a portable solution for broadcast productions using super 35mm cameras – whether HD, UHD or 4K – the CN20x50 is a tool of unprecedented quality, versatility and usability. Featuring a completely removable updated servo drive unit that enables an agile shooting style that’s difficult to achieve with typical cine lenses, the new cine-servo lens helps to meet growing demands for Ultra High Definition (UHD) resolution sport and nature television production.

Versatile and reliable

With productions today expected to shoot in demanding and unpredictable environments, a huge level of lens flexibility is required. For wildlife television, operators typically work in hostile and sensitive conditions which often necessitate shooting from extremely long distances, while sports productions typically require extremely high resolution for close-to-the-action stadium work. In both situations, operators require fast, reactive positional changes, shooting flexibility and nimble hardware that allow them to respond to changes in the scene.

Weighing just 6.6kg, the CN20x50 is conveniently portable and lightweight and offers an unrivalled focal length and zooming capabilities for its class. It enables sport and documentary crews to capture footage at a distance, while maintaining the highest quality throughout the zoom range. The lens’s huge zoom range also significantly reduces the volume of hardware that crews are required to carry, offering a superb solution for location shoots.

The latest in Canon’s cine-servo lens line-up, the CN20x50 is also user-friendly and robust. The design has been developed to ensure high levels of ruggedness and reliability, even in unforgiving broadcast environments – combining the finest quality optics with a weather-and-shock-proof construction that makes it suitable for use in the most hostile conditions when on location, to the same level as conventional Canon broadcast lenses.

Flexible operability

Compatible with a wide range of cameras, the CN20x50 also supports communication between lens and camera and will be available in both EF-mount and PL-mount variants. The EF-mount version utilises Canon’s own system, while the PL-mount variant supports Cooke’s /i Technology standard. Both models feature a 12-pin serial connection for integration with typical broadcast equipment.

The focus ring rotation is 180 degrees, balancing the accuracy required for 4K imaging with the speed needed for broadcast use. In scenarios where every second counts – and operators only have one opportunity to capture a shot – high speed zoom, iris and simple focusing operation mean that even rapidly changing scenes can be captured with ease and accuracy.

The lens’ design supports a range of cinema and broadcast accessories including operational zoom and focus controls, matte boxes and 0.8- and 0.5-type gear module accessories such as follow focus units, to provide a truly versatile solution.

CN20x50 key benefits:

  • Ultra-telephoto lens with class-leading focal length

  • Capture every detail in sports and nature TV broadcast

  • Achieve stunning shots in outstanding 4K quality

  • Enjoy a wide variety of shooting and expression

  • Portable and durable with intuitive operation

EOS Bodies / Patent: Variable Diffusion Focusing Screen
« on: October 15, 2014, 07:47:05 AM »

A patent for a variable diffusion focusing screen from Canon is out there. The patent shows a focusing screen capable of showing sharp areas as well as giving the shooter a better idea of depth of field. Current DSLRs are quite difficult to manually focus accurately using fast primes with the default focusing screens. There are focusing screens out there you can swap out, but having it all in one screen would be ideal.


Patent Publication No. 2014-191184

  • Published Date 2014.10.6

  • Filing date 2013.3.27

Canon patents

  • Spreading factor variable finder screen

  • First diffusion rate

  • Brightness priority

  • Setting of low diffusivity and high transmittance

  • Second diffusion rate

  • Blur priority

  • Setting of high diffusivity and low transmittance

  • The partially changed spreading factor according to the focusing range

EOS Bodies / EOS 6D Mark II to Move Upmarket? [CR1]
« on: October 14, 2014, 09:05:34 AM »

We’re told that Canon hasn’t been fully satisfied with the sales of the Canon EOS 6D, a camera which I personally love for its size and simplicity. We’re told that the next iteration of the camera is likely to move upmarket in features and pricing. As it sits, there’s about a $1500 difference between the EOS 6D and the EOS 5D Mark III.

I think most people would rather see a $1499 full frame camera, but Canon seems to be marketing the EOS 7D Mark II on par with the 6D as far as image quality goes, so that might drive the 6D upwards, which in turn could also move the next EOS 5D body up as well. This is the opposite of where I saw things going, but increasing margins to offset decreasing sales numbers is good business.

Lenses / Review: Canon EF-S 10-18 f/4.5-5.6 IS STM from DXOMark
« on: October 14, 2014, 07:38:21 AM »

DXOMark has completed their review of the Canon EF-S 10-18 f/4.5-5.6 IS STM lens. This relatively inexpensive lens has been receiving a lot of accolades for its performance/price value ratio.

From DXOMark:

“This lens isn’t a replacement for the existing, near pro-level EF-S 10-22mm f3.5-4.5 USM; it doesn’t match the range, speed (or build-quality) but with a similar optical performance, lower price and quiet STM AF motor this lens certainly has its place in Canon’s line-up. Knowing it will appeal to both stills and budding moviemakers it’s likely to be a popular addition, but it doesn’t really plug any holes in the maker’s range.”

EOS Bodies / "Cello" Short Film Shot With the Canon EOS 7D Mark II
« on: October 13, 2014, 01:14:34 PM »

Canon USA has posted a short film shot entirely with the Canon EOS 7D Mark II and a bunch of different Canon EF and EF-S lenses.

There’s one feature pointed out by The Digital Picture that looks to be a great feature for videographers:

“While Movie Servo AF isn’t exactly new, the EOS 7D Mark II brings a very important feature to the party – the ability to customize focus speed and responsiveness while shooting video. Take a look at the focus pull at the 2:13 mark; it’s absolutely beautiful. The ability to slow down the camera’s focus transition allowed for a very natural-looking focus pull.”

Canon General / More Canon Lens Mentions [CR2]
« on: October 10, 2014, 08:29:31 AM »

We’ve received a couple of more confirmations from people that the EF 11-24 f/4L we first reported back in August is in fact legit. The speculation on pricing for the EF 11-24 f/4L seems to be consistent across the board at around $3000 USD.

EF 11-24 f/4L

EF 11-24 f/4L

The following information is [CR1]. A separate person has told us that the EF 100-400 f/4.5-5.6L IS II was supposed to be announced at Photokina but was delayed, no reason for the delay was given. Canon themselves have come out and said that a replacement is coming, of course they didn’t specify when. We’re told to expect an announcement in November, with availability coming in December of this year. We’re not holding our breath on this one, as the 100-400 replacement has haunted us for quite some time now.

EOS Bodies / High Megapixel Camera to Come in Two Variants? [CR1]
« on: October 09, 2014, 04:48:05 PM »

An unknown person has sent us a bunch of cryptic information about Canon’s roadmap over the next 6-9 months. I have been unable to confirm any of it, but hopefully this post will help shed some light on things.

We’re told that Canon will introduce a high megapixel camera in Q1 of 2015 and it will be released in two variants. What those two variants are wasn’t mentioned. I do not see Canon doing what Nikon did with the D800 and D800E, I’m thinking that the second variant could possibly be an astronomy version, like the 60Da and 20Da. The other possibility could be an EOS and Cinema EOS version of the camera, and everyone can drool at the possibility of an affordable 4K DSLR from Canon.

It was also stressed that the cameras being talked about wouldn’t be in the $8000-$9000 range like has been discussed recently, and likely cost half of that.

More to come
