Canon Confirms Development of 100-400mm DO & More DO/EF-M Lenses

By Anthony Thurston on September 19th 2014

One of the big rumors leading into Photokina was that Canon would be releasing the new 100-400mm replacement along with the 7D Mark II. It seemed like a likely scenario given that the two products are for similar markets, and would likely be used with each other for their intended uses. However, that never panned out and the 7D Mark II was announced without the 100-400mm.

In a recent c|net interview though, Canon confirmed the development of the 100-400mm lens, adding that it would be a DO lens – which means that it will have diffractive optics. They also confirmed that they are working to expand their DO (green ring) line of lenses, so we can expect more of those in the future as well.

“a new model is in the works […]. It’s definitely on the boards for replacement[…]Canon is working to spread a technology called diffractive optics, or DO, into more lenses”

In addition to the to the above revelations regarding the 100-400mm and their DO line of lenses, Canon dropped a nice teaser for fans of the EOS-M and the EF-M system. It seems Canon has not completely thrown in the towel, and has plans to release more lenses. According to the c|net post, Canon specifically said that more EF-M lenses are on the way.

This is great news, that – to me – almost confirms that we will see a new EOS-M in the near future (sometime over the next 1-2 years). If they were really giving up on the EOS-M at the EOS-M2, they would not be developing more lenses for the EF-M Mount. To me, this means that there must be work (or if not now, that there will be) on a new body as well, even if that was not specifically stated.

      I never really understood why it took so long for the camera companies to move to mirrorless. When they moved to digital, it was the natural place to rethink the design instead of sticking with a film design that was obviously going to be rapidly obsoleted.

    Love my M, and would seriously consider a mk3 that incorporates the Dual-Pixel CMOS AF in the 7d2. More native lenses-sure!

      and not just more updated kit lenses. I want some real, quality lenses, starting with more prime lenses in the same vein as the 22mm F/2, and a good 50-150mm F/2.8.

    I would fully support the EF-M line and M mount if Canon could come up with a way to compete with the Fuji X100 series.
