Photography Bay posted a short hands-on about the new Canon EF 50mm f/1.8 STM lens, initial thoughts and sample photos inlcuded. The conclusion nails it:

If you are a Canon shooter and you don’t have a 50mm lens in your bag, the new EF 50mm f/1.8 STM is the next lens you should buy. It’s useful enough and affordable enough that everyone should consider picking one up.

The technology behind the Canon EOS 5DS and EOS 5DS R – Interview with developers


Canon Asia posted an interview with the deveolpment team behind the Canon EOS 5Ds and EOS 5Ds R. An excerpt:

Question:What was the reason for not changing the AF sensor? Was it because the performance of the system on the EOS 5D Mark III was good enough?

Answer: Yes, you are right. The EOS 5D Mark III and the EOS 5DS series share exactly the same principles of forming an image on the focal plane. It can handle any number of pixels as long as the level of accuracy is maintained. The existing AF sensor is perfectly fine since it has a sufficiently high level of detection performance.


Question: What changes were made to the existing firmware following the upgrade of the pixel count to about 50 megapixels?

Answer: The huge amount of data has a significant impact on the firmware. In order to ensure speedy and smooth data processing under such conditions, advanced and complex processes are needed, such as parallel processing while switching between the memory spaces. As there is limited space in the built-in memory of the camera, it is important to consider how this space can be utilised most effectively.

This precision housing follows in the steps of a very time proven lineage of underwater camera housings for the constantly evolving 5D camera line up. Aquatica has been on top of the 5D program since they introduced the original one a decade ago, much like the 5D camera did, our housing has evolved into a fine imaging tool that mirrors the constant evolution of technology and the input of highly respected professional’s image makers from around the world.


Now offering original internal TTL circuitry from Ikelite as an option, this 5Dsr housing edition brings creativity to a new level, strobe exposure control is right there, were it is supposed to be, you can now tweak your lighting exposure or even go fully manual right at your fingertips. Controlling the amount of light entering your camera is paramount to the success of any image maker, and the A5Dsr housing controls for aperture, shutter, ISO and strobe exposures are all a “hands on the grips” approach. Every one of these is positioned to be intuitive, eliminating confusion and making the housing a natural extension of the photographer.

In2white is a 365-Gigapixel Panorama of Mont Blanc, shot with a Canon EOS 70D

Italian photographer Filippo Blengini contacted us to share an amazing project he led and contributed to realise. In2white, the project’s name, produced the largest panoramic photo ever made.

The team led by Filippo Blengini spent 2 weeks on 3.500 meters (around 11.500 ft) to shot 70,000 photos of the Mont Blanc (Europe’s highest mountain), for a total of 35 hours (most of the time at -10 degree Celsius). The 365 gigapixel, high resolution photo can be viewed (and zoomed in) here. Can you spot the climbers?

The project was realised in 2014. The team then spent around 2 months for post-processing the 46 terabytes of footage they have shot. You may wonder what gear they used: a Canon EOS 70D, a Canon EF 400mm f/2.8 II IS, and a Canon Extender 2X III.

Filippo and his team mates describe the concept:

How to celebrate Her Majesty the Mont Blanc? We just wished to represent it as it shows to our eyes : major beauty, astonishing magnitude, pure elation.

We were brave, crazy and ambitious enough to think about a gigapanoramic picture, to seize every single detail of the mountain. We are Filippo and Alessandra, passionate of mountain, beauty and photography: here’s our concept, our tribute to the Mont Blanc.

But we were not alone in this challenge: we built a Team of dreamers and passionates from all over the World, that shared with enthusiasm our same vision and embraced our project.

Below you can watch a short video about the making of the 365-Gigapixel panorama photo.

Notice to our readers – working on site [Update]

Update: it’s done. Hope everything works fine for you.

Hi all, just a short post to tell you that I am working on a new layout for Canon Watch, along with some fine-tuning and bug fixing.

I apologise for any inconvenience you may encounter. I am trying to keep things as smooth as possible but some downtime and maybe a quirk or another (which I missed) may show up.

Thanks for your understanding!
