Interesting interview with Canon executive

It was on google tech web
This give more idea what direction Canon goCanon 1D C Canon
RedShark Editor in Chief, David Shapton, sits down with Yuichi Ishizuka, President and CEO of Canon Europe, Ltd and Managing Executive Officer - Canon Inc.
When you think about it, we have a strange relationship with a lot of companies. We know their names so well that they could almost be part of our families. We know their products because we have probably grown up with them and seen them grow through multiple generations. We may even have met staff from the company at trade shows, and met other end users, especially if weíre professionals.
But how well do we really know the company itself? My guess is not very well.
But all of that changed for me in the space of half an hour, when I sat down to interview Mr Yuichi Ishizuka, President and CEO of Canon Europe, Ltd and Managing Executive Officer - Canon Inc.
Mr Ishizuka is a cultured and thoughtful person. Heís also steeped in the history of his company. Thatís important, because a recurring theme is that Canonís heritage - which stretches back over seven decades - is an essential part of the modern company. When you have that sort of history, itís going to be much, much harder to make products that arenít good.
Of course, in 30 minutes, we were only able to scratch the surface. We are going to follow up this interview with a much more in-depth one as soon as we can. But hereís what I learned, just to give you a flavour - in the order that follows, simply because the course taken by our conversation.
R system
While this is a very new lens mount system, the planning behind it went back a long way: hardly surprising when you consider that its predecessor lasted over thirty years. The new system needed more bandwidth - physically manifested as more pins on the mount.
The R system is NOT just for mirrorless cameras. It is relevant to all of Canonís camera types - including video
C500 II.jpg
Speed to market
Canon has three fundamental technologies that are world-leading: Optics (lenses), sensors and processors. Because it makes these, it has full control over them. So itís not surprising that Canon wants them all to work together to their full potential. Thatís not easy. Theyíre working at such a high level of performance that any discrepancy could seriously affect the performance of all three elements in this technology stack.
So Canon prefers to wait until everything is just right before launching a product. Thereís obviously much more to it than this but this is the essence of it.
Mirrorless vs SLR
Even though mirrorless can create incredible images, there are still some areas where DSLRs are better. Currently Autofocus is better with DSLRs, and some photographers prefer to have zero latency in a viewfinder - although viewfinders are improving. So it might be between three to five years until mirrorless cameras are better in every way than DSLRs.
Co-operation
Canon is very open to working with other manufacturers where to do so might speed up the availability of a product. Working with Atomos is an example.
R&D
An astonishing 8% of Canonís revenue (note: revenue, not profit) is spent on R&D. Itís a never-ending quest. Some of this research goes back a long time. Canon was the first company to put a CMOS sensor in a camera. The first product was in 2003, but CMOS had been in R&D since 1985!

I not sure I can copy full and paste here interview but k mount not only one issue
They claim no interest from Pentax to cooperation and to small number order
They basically they can’t offer production with very small number-order.
Interview was 2014 nothing to much change in 2019


KY: Yes. So, we'd like to make as many lenses for Pentax as possible, but with very small demand we cannot make them frequently. For such a lens, the long back-order times are a big problem for us. So we cannot make too wide a product line for Pentax. For example, a 300mm f/2.8 -- maybe we can produce this for Pentax once every few months; but some people may need a 300mm f/2.8 now. We cannot make it so often.

DE: Ah -- you can't afford to carry a large inventory given the small sales volume, but you also have a minimum production run that's economically viable. So you end up having long lead times, sometimes. I see, that makes sense, very interesting.

[Ed. Note: I'd originally misinterpreted Yamaki san's comments here, so he clarified what he was saying in a further email exchange I had with him. I had thought he was saying that Pentax lenses were different simply because they used a mechanical aperture coupling, vs an electronic one. As several astute readers pointed out, they do, but so do lenses from Nikon and Sony.

Yamaki san's point is that lenses with mechanical aperture mechanisms require separate production runs to produce each type, vs an electronic system that would just need a different arrangement of contacts and reprogramming of the lens's CPU.

The problem for Pentaxians is that there just aren't enough of them, so demand for Pentax-mount lenses is small to the point that it's economically difficult to produce them, or at least to do so in a way that would keep Pentax users happy.

The issue is that the smaller a production run, the more costly each individual unit is, due to inefficiencies associated with switching the production line from one lens to another. As the run length becomes smaller, that fixed switchover cost become a bigger and bigger part of the cost of each unit. From a practical standpoint, there's a lower limit on run length, below which it's just not profitable for them to produce a product.

For popular lens models, the minimum production run isn't too big a problem for Pentax users, as there's enough demand that Sigma can produce a batch of lenses often enough to more or less keep them in stock in the retail channel. As you get into slightly more obscure, specialized, or perhaps more expensive glass with less demand, though, the minimum affordable production run for a given model might amount to 6 months, a year, or even a couple of years' worth of demand on the Pentax mount.

As Yamaki san explained to me, it wouldn't be viable for him to produce and market a lens that might be unavailable in the market for 6 months or a year at a time - Potential customers would become very unhappy with Sigma over the poor availability. (And, adding my own interpretation here, how could they efficiently let people know "hey, remember that cool lens we said we were making for the Pentax mount that hasn't been available for the last year? It's available now, so get out your wallets!")

At first thought, you might say "well, what's the problem, they can just build a batch of them, and warehouse them until that batch runs out, then do another run." The problem is, doing so would again increase costs, because holding large quantities of lenses in inventory would tie up Sigma's capital, meaning it wasn't available for other things that would give a much higher return. Even if Sigma were able to borrow additional money to use to hold that inventory, they'd be paying interest on it, which would again increase costs.

So, that's the full story: In my latest email with him, Yamaki san expressed what I believe was very genuine regret that he isn't able to bring more of their lenses to the Pentax mount, but can only do so for the most popular models, that will generate enough demand to be

One of our readers asked why you offer so few of your lenses with the Pentax mount, and he also asked about longer telephotos, in particular. If the mounts are fairly simple -- if it's really just a matter of changing out the mount, shouldn't it be possible to make more Pentax lenses? Or is it still just a cost issue, even for a relatively small investment?

[Note, this section has been edited 4/12/14, as I had misunderstood what Yamaki san was saying, see the editorial note following this exchange]

KY: Pentax still uses mechanical parts to control the aperture. So, mechanically, it's totally different from other mounts, even though it uses the same optics. Making a Pentax mount means we have to use special parts just for Pentax mounts.2014 interview with Sigma CEO about Pentax
