Interview

About two years after the launch of the EOS R, the EOS R5 and R6, which deserve to be called the second generation, have appeared. It has been highly evaluated by users, and even if you make a reservation from now on, it is difficult to get it by the end of the year. What do you think based on this result?

While I am very happy, I am sorry that it took a long time to deliver the product to the customer due to the great response. Without the problem of the new coronavirus, 2020 was the year of the Tokyo Olympics and Paralympics, and I thought that Japan's economy would improve. Therefore, Canon was preparing a new product, but starting with CP +, all domestic and international events were canceled, and I felt frustrated that I couldn't give a presentation as I expected. However, I was just trying not to delay this new product. We have been preparing for the simultaneous announcement on July 9th, but at the beginning of spring we couldn't see the future and were worried at first. As a result, thanks to the efforts of domestic and overseas stakeholders, we were able to announce and launch the product as originally planned when the market conditions were returning a little.

Is Mr. Tokura confident that you can answer what the user has been waiting for?

To be honest, it's as expected (laughs). Anyway, you can't fail. As you can understand from the thoughts put into the naming, since we are releasing the EOS number series, we will put more effort into all related departments, including not only the development team but also the business and production departments. I have the pride that I was. First of all, I am relieved that the result has come out.

As for the EOS R5, the development announcement was announced from a fairly early stage, and the specifications were gradually revealed, but it turned out that there was a secret ball or EOS R6 as a simultaneous announcement. Did you think about launching two models from a long time ago?

Actually, I was thinking from the planning stage, and that was exactly what I wanted to prepare for the customer.

@Sunscreen

It is just chink of copper, right?

By idea it must be special vapor chamber, as efficiency is much better.

Love the test chart results

Canon EOS R5 and Sony α1 and IBIS performance comparison

We experienced a 1/3 – 2/3 stop advantage with the Canon camera. That difference is not dramatic, and the bottom line is that IBIS is valuable in both camera brands. This feature adds substantially to the versatility of non-stabilized lenses, such as the 50mm f/1.2 models tested here. IBIS is one more reason to love the latest mirrorless camera models

Well, the R5 actually does not overheat outside in cold temperatures. My pocket 8K RAW rig: the R5 + RF 35mm lens - fits in my parka pocket. And it is very versatile, indoors and outside:
