A7 & A7 R Spec: http://www.sonyalpharumors.com/a7-and-a7r-specs/

A7 seems to fit my needs - Faster AF, with 117 points (phase-detection AF),

I hope their PDAF in mirrorless body works well. On the Nikon V1/J1, they are next to useless when light levels fall (see DPReview write-up on V1/J1 PDAF).

50mm on FF format.

I think IS for Sony isn't in the lens.  It's in the body.  One major advantage for mirrorless is the fact that there's no mirror and the form factor is smaller than a DSLR.

If the rumored specs are correct, Sony A7/A7r do not have in-body image stabilisation. A pity. :o

It's fairly clear the small body form factor isn't too popular, otherwise Sony would not have released the A3000 (mirrorless body that accepts NEX/E-mount lenses but with a DSLR camera form factor). ;D As Thom Hogan says, Sony is going all over the place without any clear direction, as they desperately try to grab more market shares.

But so do the new FF mirrorless Sonys.  The appeal isn't so much the size (it might be a nice upgrade from the Micro 4/3 equipment I have, but it's so good that I'm not sure how important that is) but the fact that they're mirrorless, with all the advantages that come with that.  New, small lenses would be nice, but I'm as interested in trying some of the highly regarded Minolta lenses, which might be a bit awkward to use on a tiny body...

Toss in the new sensor technology that Fuji and Panasonic are supposedly working on - which may render FF obsolete - and it all becomes simultaneously confusing, interesting and enticing....)

Since Sony is rumored to release the following lenses: 35 f/2.8, 55 f/1.8 and 24-70 f/4 (all without stabilization), I am curious how their weights will compare against Canon's equivalent offerings, 35 f/2 IS, 50 f/1.4 and 24-70 f/4 IS. If they are similar to Canon's offerings, then I really do NOT see any advantage to Sony's concept.

Having used the EM5 for a year, I find that I intensely dislike mirrorless cameras for 2 reasons: (i) EVF (color and brightness never the same as OVF, no matter how fast and high resolving they are) (ii) poor handling, difficult to grip. Since Canon has demonstrated what they can achieve with weight reduction in the 100D, I am hopeful they can produce low weight DSLRs bodies in future.

FF can never be made obsolete, just like medium format never really goes away. Larger sensors will always have shallower depth of field and better resolution.

I am not a die-hard DSLR fan. I am willing to try out mirrorless stuff too, but at the moment, they simply cannot match my DSLR experience. I plan to use my 6D and 70D until 2020. Hopefully, some breathtaking technological breakthroughs happen by then. :)

You mean that test DPReview did trying to focus on the white eye of a white marble horse?? Then they tried to use the USB dock and stated that it took several hours to configure it?

Curiously, because the new Canon 24-70/2.8 wasn't that great on the 650D, they felt the urge to specify that "As always, though, it must be noted that focus speed and accuracy is dependent upon a number of variables, including the camera body used, subject contrast, and light levels."

My experience with the Sigma 30 f/1.4 (ART) lens exhibits the same symptons of inconsistent AF even with highly contrasting subjects. All the microadjustment won't help inconsistent AF.

Oh my God! ... the lens isn't even out yet but people already know it has "inconsistent AF" and that too from just knowing that it is "much heavier" and that it has "82mm filter size" ::)

On Sigma website before it was taken down:
    Lens Construction: 19 elements in 14 groups
    Dimensions (Diameter x Length): 3.5in x 4.3in
    Maximum magnification ratio: 1:4.6
    Weight: 885g / 31.2oz
    Minimum focusing distance: 45cm /17.7in
    Angle of view (35mm equivalent): 84.1°-23.3°
    Filter size: 82mm
    HSM delivers high AF speed and quiet performance
    Offers F/4 brightness throughout the zoom range
    OS (Optical Stabilizer) functionality
    Super Multi-Layer Coating reduces flare and ghosting
    Rounded 9-blade diaphragm
    Mount conversion service available
    Sigma USB Dock compatible

As for inconsistent AF, well, I had the latest Sigma 30 f/1.4 DC (ART) lens. Used it for a week and got rid of it. DPReview had similar problems with the Sigma 18-35 f/1.8 lens. The Sigma 24-105 f/4 won't be any better... of course its f/4 aperture may help to mask some of its AF problems.

Much heavier. 82 mm filter size. The same old same old Sigma inconsistent AF.

No, thanks. I'll pass.

I never read about the "they spent a lot of time" and onwards part before. Where did that get documented?

You'll need to comb through Rob Galbraith's website: his long series of articles on 1D Mark III AF, various preludes to aforementioned articles as well as his criticism of Canon's offerings after the 1D Mark III. The info is all there.

Ultimately, like what others have pointed out, why do you think Rob Galbraith finally had to quit his job?

Except that the "fix" never really fixed the problem completely.
http://www.robgalbraith.com/multi_pageb10a.html?cid=7-8740-9068-10086

So says Rob Galbraith... who has since then retired into anonymity.

Also, Canon at least had the courage to own up to the problem. Nikon, on the other hand, has never really fessed up to their issues.

"The sad thing is that this isn't the first time Nikon's been unable to fess up to a problem. This is now endemic with them. As Michael Johnston at Online Photographer points out, this sort of problem denial goes way back into the film days for Nikon..." - http://www.dslrbodies.com/newsviews/the-early-nikon-d610-headli.html (Thom Hogan, a loyal Nikon supporter)

Its good for all of us. Don't get wadded up on the fact video features are part of the team now too.

It all sounds good except Canon seems to be crippling the video capability on their DSLRs... Don't believe? Just look at what MagicLantern did with video features on Canon DSLRs. Ironic isn't it? They are afraid DSLR sales will eat into their camcorder business. ;)

We’re also told any follow-up to the EOS 7D will get a new sensor and not use the 20.2mp sensor that is found in the EOS 70D.

The sensor may be different, but the still image quality will be nearly the same, just like the 70D 20 MP sensor vs 700D 18 MP sensor. IOW, zero improvement in dynamic range. ;)

Depth of field isn't everything to everybody.

Then, why get FF? The EF-S 60 mm f/2.8 macro is just as good. :)

Make it an EF 50mm f/2.5 USM IS Compact-Macro with the same 1:2 magnification, and perhaps weather-sealing, then I'll be interested. Otherwise, what's the point of it either not being f/1.4 or super-cheap? It's one or the other.

The difference between f/1.4 and f/1.8 is merely 0.67 stop. Change in DOF is not significant.

Now, between f/1.4 and f/2.5, the difference is 1.67 stop... that is significant. I will not get a 50 f/2.5 lens, useless to me.

Here’s what’s probably one of the last deals we’re going to see on this camera.

But when is the replacement coming? Still no CR2 info... What's Canon waiting for?... Clear their warehouse goods or for Sony to announce their NEX-FF systems...

Maybe Canon will come up with a comparable pancake?

Pancake lenses are never very fast (f/1.4).

The closest lens is the Canon 35 f/2 IS.
