Canon Announces ME20F-SH Cinema Kit for Filmmaking and TV Production



Canon ME20F-SH camera





I have just returned from a rather successful wildlife photo trip to India. Witnessed two tiger kills from beginning to end on a Spotted and Sambar Deer plus Elephants and Monkeys mating, in addition to many new bird species for me. Trying to get back to writing my blog and catching up with the latest photography and NAB 2016 news. It will take me a week or two to get back to speed and precious little time to process the photos because by then, my next tour will be here already. I have a very busy Spring and Summer touring season ahead of me. You can see my works on MichaelDanielHo.com


MELVILLE, N.Y., April 13, 2016 – Canon U.S.A. Inc., a leader in digital imaging solutions, today introduced the ME20F-SH Cinema Kit, which bundles the ME20F-SH Camera with 10 accessories to enhance the user operation and provide significant savings compared to purchasing the accessories separately. The ME20F-SH camera’s CMOS sensor has pixels measuring 19 ?m square1, which is more than 5.5 times the surface area of the pixels on the CMOS sensor featured in select top-of-the-line interchangeable lens cameras2. Its large pixel size enables the ME20F-SH to deliver magnificent imagery in normal lighting conditions, while also possessing the high sensitivity to capture Full HD video in less than 0.0005 lux3 (at maximum 75 dB gain setting, equivalent to an ISO sensitivity of more than 4,000,000). Along with its modular body and compact size, the image quality delivered by the ME20F-SH camera allows users to capture clear images in even the most demanding of applications including cinematic production, reality television, and nature/wildlife documentaries.

“We’ve been using the ME20F-SH camera to simulate military-grade night vision goggles and no other camera can simulate night vision goggles like this – it’s the only machine that could do what we needed,” said David Klein, ASC, cinematographer of The History Channel’s upcoming drama series SIX. “The camera takes sensitivity to a new level; its high end is not just noteworthy, it’s mind blowing. When we shoot with the ME20F-SH camera, nearly every light is turned off or knocked down to nothing, and the camera does the rest,” added Dominik Mainl, SIX’s First AC.  “I know this camera is capable of over four million ISO, but we found a remarkable singular image around 600,000 ISO, where signal to noise ratio was suddenly irrelevant.”

Similar to Canon’s Cinema EOS System of professional digital cinematography cameras, the ME20F-SH camera includes Canon Log and Wide DR, which make possible a wide dynamic range, delivering high-image-quality video results across a range of illumination environments, from low- to brightly lit conditions. The ME20F-SH employs the same EF mount (Cinema Lock type) as Canon’s SLR cameras and Cinema EOS series of professional digital cameras, allowing users to make use of the Company’s extensive lineup of interchangeable EF lenses from fisheye to super-telephoto.

The ME20F-SH kit accessory list includes the Atomos Shogun Flame external recorder, Zacuto mini baseplate, a SanDisk SSD pack, Noga Arm, HDMI cable, additional battery, battery and cheese plate, D-Tap/D-Tap cable, XLR cable and a battery charger that can also be used as a power adapter. All of these accessories make the ME20F-SH Cinema Kit ready for film and TV production as well as documentary work across a number of genres.

“Since its introduction in 2015, the ME20F-SH camera has been an incredible tool for cinematic production,” noted Tim Smith, senior advisor, Film & TV Production, Canon U.S.A., Inc. “It produces phenomenal light sensitivity that enables incredibly clean images in standard lighting conditions, and remarkable color imagery up to ISO 4,000,000 even in extremely low light. This new Cinema Kit empowers filmmakers to have a turnkey solution to shoot with minimal lighting equipment or additional gear.”

The Canon ME20F-SH Cinema Kit is expected to be available in April 2016 at a suggested list price of $31,000.* For additional information about the camera and this new kit please visit : https://www.usa.canon.com/internet/portal/us/home/products/details/cameras/multi-purpose-cameras/me20f-sh.

Canon Interview From CP+ Show 2016




At the recently concluded CP+ Show in Yokohama, Japan, DPReview interviewed Mr. Go Tokura, Canon's Group Executive of Image Communications Products Operations. Below is an excerpt from the interview :

Canon has had a big year with the launch of the enthusiast-focused EOS 80D and the professional EOS-1D X Mark II. Can you summarize your strategies for catering to these two different market segments?

With regard to the EOS-1D X Mark II, this is an Olympics year.  In years when the Olympic Games are held, one of our objectives is to launch a flagship model within our DSLR lineup to try to capture the professional user market. So this is a big objective in terms of strategy.

As for the EOS-80D, we have entry-level DSLR models under the Rebel brand and the 80D is the level just above - designed to ensure that users can maximize its features in the best way possible. That’s in terms of price, operability, usability and that sort of thing. In recent years the entry-level market segment has been weakening, but the level above that, where we’re targeting advanced amateur users, is becoming an increased focus. The 70D is doing well and is quite popular among our users, and for that reason we expect a lot of interest in the 80D.

Some of our readers were disappointed that the 80D does not include 4K video. Why did you decide not to include this feature?

As you know, in our DSLR lineup we incorporate both video functions and traditional stills DSLR functions. Among our DSLR users we’re still seeing a strong emphasis on the stills photography function.

We’re promoting our DSLRs as providing both stills and video features - the best of both worlds, you might say. However with regard to the 80D, the main emphasis was to maximise the stills side of the camera. Then, with the aim of increasing the user base, we add movie features to this established stills shooting feature set.

Do you think there is space in the enthusiast DSLR market for a more capable video camera? Which maybe does offer 4K?

We are considering this and we recognize that this is a feature which might be in demand in the future.

Do you think that Dual Pixel AF will ever be equal to conventional phase-detection DSLR focus, and if so, when will this happen?

It’s very difficult to predict timing, of course, but we want to make Dual Pixel CMOS AF surpass conventional phase-detection in terms of performance.

Dual Pixel AF is a technology which has huge potential for mirrorless cameras. A lot of our readers are still very hopeful for future Canon enthusiast mirrorless models. Is there anything that you would like to say to them?

Obviously I can’t be particularly concrete when talking about our future product planning, but this is something that we are looking at. Something that is under consideration. There are some features, such as AF, which have not yet caught up with DSLRs, so given the current state of affairs it would be a little unrealistic to say that we will suddenly start offering a professional mirrorless camera. There’s still a performance gap that needs to be addressed.

If we assume that at some point in the future Canon will create an enthusiast or professional mirrorless camera, what are your benchmarks?

This is just my personal opinion. In my view there are two key features that have to be addressed. The first is autofocus, particularly tracking of moving subjects. The other is the viewfinder. The electronic viewfinder would have to offer a certain standard. If those two functions were to match the performance of EOS DSLR camera performance, we might make the switch.

Tremendous progress has been made in electronic systems.  However in terms of AF, pro-level AF functions, and the range of shooting situations that professional photographers can respond to, there’s still a gap between DSLRs and mirrorless systems.

When I spoke to Mr Maeda last year he told me that he was focused on increasing the speed of product development at Canon. Have you seen a change?

I can’t give any concrete details here but this is a goal that we’re working to achieve.

The reason I ask is that it seems that compared to the past, the entry-level ILC market seems to be moving rather slowly right now, whereas in terms of development speed, the enthusiast and semi-pro ILC market is moving quite quickly.

Yes, I agree. For this reason, it’s becoming increasingly important that we do increase development speed.  That’s why it’s considered a very important objective that we’re continuing to address.

What is your strategy for growth in this changed market? What do you need to do to differentiate?

One of the differences between us and our competition is the EF lens lineup. We have a very broad base of EF lens users and we don’t want to do anything that would sacrifice their loyalty, so it’s a very high priority for us to satisfy their needs and meet their demands.

With regard to the overall market, maybe there’s a lack of vigor and it could be viewed as shrinking. Looking at the compact camera market, the bottom end is dropping considerably and the competition is smartphones. Smartphones offer a very easy, convenient way of taking photos. However in the high-end compact segment, at the high end there are cameras that offer functions and performance that smartphones cannot compete with and here we’re seeing growth. So in the compact market, offering features that smartphones cannot compete with is a way of differentiating and invigorating the market.

You mentioned loyalty. How important is it to you to continue to update older models via firmware even perhaps after end of life?

Of course we’d like to provide every level of support we can, even to users of older models. Should an opportunity arise we’ll obviously offer firmware updates so that they can get the most out of the models that they have purchased. However a lot of the performance depends on the hardware itself. There is only so much you can get out of older or out of date hardware. There are new devices incorporated in newer models which make possible improved performance, so there’s a kind of tradeoff. Unless newer hardware is introduced, sometimes it’s not possible to get the performance.

One of the areas where we’ve been pleased to see improvement from Canon is in sensors. What are your priorities in terms of sensor development in the future?

Increasing resolution and increasing sensitivity are ongoing objectives and that’s not going to change, but on top of that, as I’ve mentioned there’s an emphasis on merging stills and movie functions. So two priorities for future sensors are lower power consumption and increasing processing speed.

As you develop semi-professional lines like the EOS-5D and EOS-1D series, where are you most focused in terms of improvement?

When we look at a model that we want to upgrade, we don’t take a single item of specification and choose to work on that and not other aspects. We try to improve all features to the same degree. The EOS 5DS however was an exception. Resolution was increased markedly, off the charts compared to anything we had done before. But that’s the exception. Usually we won’t try to boost any one feature over and above the rest of the feature set.

Our approach when it becomes time to launch the next generation of the EOS-1D X or the EOS-5D, is that we try to raise performance across the board as best we can.

Canon EOS-7D Mk II and Dual Pixel CMOS AF




* * *  EOS-7D Mk II camera announced  * * *


Last year, Canon announced the EOS-70D camera with the ground-breaking Dual Pixel CMOS AF technology to rave reviews. A few months later, I reported Canon is ready to take this new revolutionary system to the next level and introduce it to other cameras in their lineup.

With the imminent release of the Canon EOS-7D Mk II on September 5, my sources informed me the new camera will come with a brand new sensor to bring the Dual Pixel CMOS AF technology to new heights. In the last year, Canon has been filing patents similar to Foveon sensors, with one patent showing up to 5 layers, 3 layers for RGB, 1 for IR and 1 for UV.

The current EOS-7D camera has dual DIGIC 4 processors but Canon may even skip the DIGIC 5+ processors in favor of the DIGIC 6 to power the EOS-7D Mk II, in order to maximize the potential of this new sensor. You can see my works with the present camera from worldwide photo shoots on MichaelDanielHo.com. Keep checking back for the latest info and development as I get more 'leaks' from my sources.


Possible specifications of the EOS-7D Mk II camera :

  • 20+ MP APS-C Sensor ( With new, breakthrough technology. Stay tuned )
  • Advanced Dual Pixel CMOS AF technology
  • Dual DIGIC 5+ or DIGIC 6 processors ( Excellent for speed processing )
  • 8 - 10 fps ( Most welcomed by me ) 
  • Dual Memory Card Slots ( One CF and one SD. I prefer 2 CF slots )
  • 45 -61 AF Points ( Perhaps similar to EOS-1D Mk IV and X )
  • 3.2″ LCD monitor ( Excellent for reviewing images )
  • 100% coverage viewfinder. Magnification 1.15
  • Similar build quality as the EOS-5D Mk III with improved weather proofing
  • Comes with GPS and WiFi ( Not necessary, in my opinion ) 
  • ISO Performance may equal EOS-5D Mk III ( Most welcomed by me )
  • Latest video features similar but more advanced than EOS-70D 
  • Selling price between $2,000 to $2,199. Not finalized yet
  • May be announced with EF 100-400mm f/4.5-5.6L IS II lens
