A company like Canon has no product roadmap? That is completely laughable. Every large corporation lays out roadmaps for their products, releases, etc.
What I heard was:
- Other companies produced roadmaps for lenses that never came true, so they aren't going to publish their RF roadmap and look like dolts.
- They have to catch up with the mirrorless competition so all efforts in 2019 is to build up the RF base because they are behind
- Their EF lens collection is quite large and complete as is (and he is correct), so they don't have a publishable short-term roadmap of new EF lenses at this point
What I saw is exactly what we go through internally when we have meetings about how to talk to our customers. Marketing speak is rehearsed and laid out long before one of us in management or marketing or customer service sit in front of a customer. Been there, done it, many times...
That doesn't mean they are done with EF, EFS, or EFM lenses, unless you take that out of context and ignore all other things that was said. It just means the EF line has reached a product maturity level where they don't need to keep introducing MKIII and MKIV version of the same lenses they have been creating for years, and other areas require their attention currently.
First Canon has to get the mirrorless to the level of the 5D4 and 1DX2, then nobody will really care about DSLRs and new lenses for those bodies. However I see no reason why there won't be 3-4 DSLRs introduced in the next few years along with a few EF/EFS/EFM lenses. Past that, I am sure that well will dry up, but that provides time for Canon to develop and tune the mirrorless line, while still retaining marketshare.
Soccer parents don't care about any of this, they just want an economical camera with 2 or 3 reasonably priced lenses to shoot their kids events, and they still make up a large part of Canon's customer base. That means DSLRs and cheap lenses for a bit more yet, or enhance the M series and EFM lenses. The only alternative to this is that the next EOS-R camera announced will be a Rebel replacement with some new low cost RF lenses.
Maybe we will get an RF 75-300, won't that be fun! Can't wait for an RF 18-55, RF 55-250, RF 18-135, RF 100-400, RF 24-70, RF 12-24, etc. Of course I would be more interested if they create some unique ranges this time around with a bit faster glass. That will catch my attention.
