Patent: Full-Frame fixed lens camera

security camera lens maybe?

Swerky · Feb 22, 2021

15-45? If it's meant to be a fixed lens for something like a full frame G1X, I imagine at those apertures, it would be much more useful to have a 20-70. Or 18-60.

why it needs to be a fixed lens?

Market segmentation, it would be a beefed up P&S which have been decimated because of their small sensor size.

I’m with Craig on this, I always wanted a Canon RX1 as the high quality 35mm fixed lens suits my walk around style perfectly. But goodness the actual RX1 ergonomics put me off every time I pick one up!

I’m sure there is a small market for fixed lens >$2,000 P&S’s, I’m not sure that includes f4.5-8 lenses though so I’d see this much closer to the $1,000 price point.

Those two front elements aren’t going to be cheap to make.

It is a bit strange to me that Canon did not announced anything this year and we are in March almost. Was like this before of this is just pandemic delays?

I think the reason to make such a "thing" for fixed lenses is maybe the group near the sensor which is very close to the sensor AND has to be moved for focusing.
At f/8 some 30 MPix seem reasonable in my thinking - maybe some EOS R sensor reusage project without OVF and lower number of controls (no touchbar

. First I thought the RP sensor would be good but I think a little bit more DR would fit an ultra wide which usually captures a lot between bright light sources and dark shadows.

I think this is a big reason because they make lots of profit from selling large numbers of e.g. M50s or similar cameras during holiday seasons and holidays aren't close if schools are closed (at least here in Germany).

Looks like it. Drawing 7 of the patent shows an implementation for a surveillance camera.

Larsskv · Feb 22, 2021

Why would you buy a full frame surveillance camera with a slow lens like this?

I could see myself wanting a small FF camera with a small and slow lens, for hiking and certain travel and daytime photography, but the market for such a camera is probably quite limited.

And I was hoping for the Canon version of an X100 oh well

Tangent · Feb 22, 2021

I wouldn't mind a digital version of the good old Olympus Stylus Epic -- fixed 28 f 2.8 lens. Fixed fl: no longer than 35, no slower than 2.8. Simple and affordable, too -- that was part of the charm of the Olympus!

(An Epic in good shape is worth more now than it was new... that kind of indicates there would be a market for such a cam.)

LOL 15-45 f/4.5-8. I'm sure the fan boys with squeal with joy becuase it will be soooooo light.

ozwineguy · Feb 23, 2021

Absolutely with you on the desire for a Canon version of a Leica Q. I'd be all in on that for my walk around. Love my R5, but give me something with an f2 fixed focal length lens (28mm, please, not 35mm) and you've got me. Especially if they implement a leaf shutter a la X100. I had an X100F and it always had the 28mm-equiv converter on there. So give me full frame, Canon colours (I do like Fuji colours, but prefer Canon), and a solid lens, and I'm sold.

Robolon · Feb 23, 2021

That 15-45 on a FF-Sensor seems interresting. The f/4.5-8 can be compared to some P&S cameras on the market (if you account for crop factor). I imagine, Canon might put that 20MP Sensor of the R6 or the 45MP Sensor of the R5 behind that lens. That would be an interresting combination.
15mm beeing wide enough for these vloggers. But I am sure people will complain about that dark aperture...

Antono Refa · Feb 23, 2021

I don't see a market for a P&S that doesn't have both wide and tele long enough to shoot portraits, say 24-70mm in FF terms, all the more so if its an expensive FF camera.

Why would security cameras have FF sensors, rather than m43? What's the usage scenario?

With today's sensors' high ISO performance, and shallow DoF not being a priority for UW, I can see Canon offering an RF 15-35mm f/2.8L and a 15-45mm f/4.5-8 side by side.

Patents are also here to avoid competitors to make similar things. It is a kind of defensive tool, not only a plan for a new product

From what I know, security cameras have small sensors, not even m43. With the low resolution those operate (often 1080p or even 720p) they still have large pixels. The dark aperture on the other hand isn't a preoblem for security cameras, you often focus to some distance and you want the maximum DOF...

A 24-70 on a P&S camera would certainly be more useful. But even a 24-70 f/4 would be rather large and heavy on a P&S camera.

You are right.
This might never even be a real product, just a patent so noone makes that product.

The fact that security cams have traditionally had bad image quality does not mean it always has to be like that. I can imagine a demand for mor resolution and low light capability to enable for instance face recognition. Even in non-totalitarian countries.
