Would a new Canon Mirrorless ILC System replace the EOS System?

[JackM]

This is probably the most interesting thread - for years

I'm a bit surprised that no one mentions the problem related to
the uwa and wa lenses of the 'M-like' design. For a long time
the debate was about the technical ability of a FF-sensor to react
properly to the light hitting it at angles far from 90 degrees.
Has this problem been solved?

Gee I think so... at least judging from my experience with my 5DII and 17-40L. Is there something about the M-like design that would cause a problem?

you're so very right here

indeed M-mount short flange distance exacerbates the problem of
very oblique angles in UWAs even more in digital

...with a direct bearing on this problem few weeks back:

which discusses how efficiency might be increased on sensor's
periphery,

As far as I know the problem isn't really solved. You might change the position of the microlenses or deal with it via software/firmware.

On the other hand: Take a look at the Panasonic 7-14mm lens (14-28mm in the 35mm world) - results are great. So at least with 2x crop sensor of m43 the issue is not really an issue.

But for a large sensor design in a small body things get much more tricky.

However, I don't see a FF mirrorless camera in the near future (beside Leica of course and here you have to deal with issues in the corners).

I would seriously consider buying a CL- or M4-2-like body with
canon 5DII type sensor and electronics.

Sorry that I didn't read all the messages but only about half of them.

I just want to say that I want a mirrorless canon as well. If possible please add a sensor based PDAF and with a EF adapter, all current lenses can be used with no problem.

 

[buellom]

Well, that's the challenge. EF lenses work with phase detect AF, mirrorless systems can't and work with contrast detect AF.

Olympus gave up to bring together 43 (PD AF) and m43 (CD AF). Sony seems to introduce an adapter for E-mount cameras with translucent mirror that enables PD AF for all the alpha/ Minolta lenses. Smart appoach, but I don't like the idea to loose 1/3 stop of light.

What Canon (or Nikon) is going to do, is still uncertain. If Nikon really introduces a 2.7 crop system, I don't think it will be compatible with DSLR (PD AF) lenses.

As a matter of fact, talking of Panasonic m43, I remember the embarrassment here on DPR when it came out that the testing of the highly praised Lumix G 20mm F1.7Asph was flawed after it was disclosed that this lens was in-camera software corrected.

And talking about WA and UWA correction on FF sensors, have you ever turned the corrections off on DPP raw converter and compared the results?

I just mentioned these thoughts to underline that i.m.h.o. corner problems shouldn’t be an issue on the much expected FF digital mirrorless.

I.m.h.o. if Canon brings out a new line of a simple and stylish digital FF mirrorless camera with OVF (Fuji x100 / Leica M9 inspired) with small lenses, it would become an instant hit comparable to the Ipad success.

It wouldn’t replace the EOS/EF line. It would just enhance it for an other style of shooting.

There’s no question that it wouldn’t be ideal for certain applications such as BIF or Macro, but all the EF lenses are available and could easily be used with the provided converter and the live-view feature.

Believe me, it would not only be the camera of choice for all photographers looking for a lighter top quality day-to-day walk-around shooter, but also the 'must have' gadget for trendwatchers. An instant bestseller ..

I would order one today rather than tomorrow ..

...nothing of real interest in the recent announcements from
canikon, not only about any Barnak type but actually no ILC
of any type at all - disappointing !!

I think part of whats standing in the way of a FF mirrorless body is that the format is already reasonabley compact. A 5D really isnt that big a camera to lug around unless your using long tele lenses which mirrorless isnt best suited for anyway. When your talking a mostly ammature and not very serious crop market the weight saving is easy to sell.

Medium format on the other hand seems very different, the lightest option right now seems to be the Pentax 645D and your looking at over 2KG with the body and a pretty modest zoom and thats with a sensor only 25% bigger than 35mm.

Sony seems to have made a little more expensive APS-C based mirror less camera (attracting street photographers and Range Finder enthusiasts? but still aps-c).

Panasonic made a small/collapsible zoom "X" lens (future similar market as Canons L-lenses?) for their mirror-less cameras. This is what the mirror-less market needed.
(Oly have a cheaper and smaller version?)

For Canon to top all of this, they only need to make a micro-5DmkIII with collapsible micro-L-lenses and they will be the new RF/'Leica' ...
(Image stabilization need to be fitted in either the lens or body though)
