EOS Bodies / Re: Patent: Improved EF to EF-M Adaptor
« on: February 24, 2015, 02:15:02 PM »
The master lens is called   EF-M 70-200  f/2.8 IS    in the patent (strange?!) ...

But I am confused by the EF-M 70-200 ...

The patent makes no such reference.  Egami's blog does.
The lens isn't named in the patent filing.
Egami refers to is as EF-M 70-200 in one place, and just as 70-200 elsewhere.

I wouldn't take machine translations as gospel  ;)

To be clear, it isn't a patent for an "EF to EF-M adaptor", as the patent makes no references to any particular Canon product line. Rather it applies to "interchangeable lens devices" when using contrast-based AF (and is not specific about mirrorless).

In fact the patent primarily uses the term "D-SLR" to describe the camera the adaptor is used with. (but that's just an example I think - the patent isn't specific to DSLR)

They have also updated "EOS Remote" and you can download the full resolution JPG files:

If you are shooting JPG+RAW, you can download the full JPG file. If you are shooting only RAW, you get a downscaled (1920x1280) JPG file only.

I can only see 1.2 available for iOS in UK.  Not 1.3 available yet.

Working fine with my 70D and iPad.

Except I couldn't find a way to get the preview to AF without taking a shot at the same time.
I can use the MF controls to manually focus.
But if I press the shutter release it AFs and takes a photo in the same action.
So I can't see a way to pre-focus.

UPDATE:  Found a "show AF button" in settings. That solved it.

After watching the video over and over again I am now convinced that the focusing speed is still the weak point of this camera if you look at the video at 2:15.

I don't think that particular clip is a valid indication of single photo AF speed, as he is shooting a video at that point, and is pulling the focus from one point to another. In a video you often want a smooth, slow transition and the M purposefully does that.

If you look at the lens used at location around 2:22 in the video, you can make two observations:
1) the front lens element is quite large. EF-M 11-22, 18-55 and 55-200 lenses all have a large front element too, but
2) the text around the front lens element takes only about one third of the full circle around the element. In EF-M 11-22mm, 18-55mm and 55-200mm lenses the text takes about half of the full circle around the front element. Also the text is different from Canon EF 50mm f1.2 L, and like noted, the lens is too small to be EF 50mm f1.2 L.

So a new EF-M with large 1.2 aperture after all...?

I don't think so as if you look closely that lens appears to be on an adaptor.  It seems to have that distinctive shape where it gets larger to accommodate an EF lens.  Of course it could also be an adaptor for another mount. Perhaps it could be an old FD lens even.

OK. Seek and you will find. :)

With a special mount adapter you can even use other Canon lenses. In our work as photographers we shoot with 5D cameras and lenses of the L-series, which we could also use on the EOS M3. For example; we’ve tried the 50mm f/1.2 lens on the EOS M3 camera while filming and we were so impressed with the results; super crisp quality with a beautiful and dreamy depth of field.


So there you have it

I think the clip might be edited and the view being showing on the LCD is not from either of the cameras the man and woman are using. Its from the cameraman who is filming them both.
You can see the lens the are both supposedly using in the clip at 2:15 onwards as they show each of them taking photos of each other, with the LCD showing F1.4 and F1.2 in their cameras.  But the lens on the ladies camera that is supposedly shooting at F1.2 has quite a small front optic.  It doesn't look F1.2 capable, though perhaps a M mount requires a smaller than FF.

Also at 1:26 in the antique store it looks to me like she is using the EF adaptor - you can see the shape of it in a couple of shots, and is clearly not using an existing EF-M lens.

EOS-M / Re: Official: Canon EOS M3 and It's Not Coming To North America
« on: February 06, 2015, 11:55:28 AM »
Of course $799 mirrorless will sell poorly compared to $799 DLSR, when it has slower AF, less FPS, shallower buffer, NO viewfinder, weaker flash, and we could go on and on. It´s really poor. Did Canon people sh!t themselves in pants? What do they smoke? I like M3 very much, but there is NO chance to buy it for that price. It IS DOA in Europe for sure.

The M3 is cheaper than the new DSLRs in Europe though.
The M3 kit is £90 cheaper than the 750D kit.
The 760D price hasn't been announced as a kit yet, but the body only is £50 more expensive than the M3 kit.

Whether £599 for the M3 kit is still competitive with new MILC cameras from other manufacturers is another question of course.

Just to add to the suggestion it could be an EF-M lens, Canon did patent it
http://translate.google.com/translate?sl=auto&tl=en&u=http://egami.blog.so-net.ne.jp/2013-10-25

Canon is 35 mm F1.4 , 50 mm F1.4 , 50 mm F1.8 of patent and, with a accessory shoe mount adapter is pending a patent on. Since the patent application of the optical system corresponding to the APS-C mirrorless, I want to expect the expansion to the EOS-M.

If it has IS, I will be tempted.
But somehow I doubt it. I think this will be priced too cheaply as a replacement for the current 50mm F1.8, and the price point won't accommodate IS.

That said they manage to put IS in their kit zooms. But even they are priced higher than the current 50mm F1.8.

However, if the price point is something more like $200+ in keeping with the 40mm F2.8 STM then I would think there is more chance it will have IS

I would like to see a EF 50mm F2 IS
This would be consistent with Canon's updating of its prime line in recent years, bringing out IS versions.

I've tried 70-200 f2.8 IS II + adapter on eos-m Vs native 22mm. AF speed is not the same. Why? I can't tell you.

Neuro confirmed his adapter + L lenses is faster then native 22mm. Maybe, other members can give their feedbacks.

Hardly a valid comparison though as it is two different lenses. It doesn't demonstrate that the adaptor makes a difference....

The fastest focusing lens I have used by far on my M is the EF-S 55-250mm IS STM - via the adaptor - it is faster focusing than any native EF-M lens hence demonstrating the adaptor has no impact I can see. My belief is because it is able to house a bigger STM motor than the EF-M lenses, and the M is optimised for STM lenses. It is faster than my EF 70-200 f2.8 IS II. Nothing to do with the adaptor AFAICS.

So, I can't see any reason that a new adaptor is needed for the M

The MOST important factor for Canon to gain ground in mirrorless world is EF adapter to mirrorless. If they can come up with adapter with decent AF speed, better than current ones on the market, I think that will give Sony, Fuji etc... good run.

Enlighten me on why they need an (EF adaptor to mirrorless) "adaptor to mirrorless with decent AF speed"?

In what way does the current EF-EOS M Mount Adaptor affect "AF speed"? And how would you improve it?
Or are you talking about some other adaptor?

For Canon shooters, standard EF and L lenses are as good as gold. These lenses can still be used with EOS-M system with an adaptor, however, AF speed becomes slower.


The adaptor doesn't make AF slower though does it?
It is the EOS M body that has slower AF.  All the adaptor does is pass through the signals, doesn't it? It is just electrical contacts.
I can already put my EF and EF-S lenses on my EOS M.  I don't need a new adaptor for that.
What I need is a new EOS M AF system that focuses them quicker.

I will repeat, in what way does the current EF-EOS M Mount Adaptor affect "AF speed"?  (I am actually interested to know, as I am not aware of it.  Not keen on having to buy another adaptor as well as a new M!)
