If they release a digic 6+ with the same kind of performance gains the 5+ saw, it will be very capable.

True, and then I would have been proven wrong. So that is why I am very interested to see what Canon puts inside the upcoming 7D2 camera.

How much space are you actually saving with a Sony A7 mirrorless camera as some have recommended?  Since you can't take a picture without a lens attached, the answer is not much at all!

See below comparisons:

But look at the differences in height and weight.

I feel that as soon as you start even considering the 6D, then the perceived mediocre AF of any mirrorless camera falls away.

That was a camera developed for release in 2009. They probably don't need dual processors to do the same in 2014 (the pixel throughput of the 5D3 is nearly 93% of the 7D even though the former only has one processor).

The 1DX also has dual-processors, plus a third to lend a hand ... for 18MP @ 12fps.

The fact that in a camera developed for release two years ago they didn't use a modern core indicates they don't have a modern core now?

The very fact that there are more capable processors than the (old'ish) DiG!C 5+ can only mean that Canon is behind ... either in terms of actual know-how or due to patent constraints. So it will be very, very interesting to see what processor(s) are placed inside the 7D2.

139
The 1Dx does 12 fps raw or 14 fps jpeg and is 18mp.
So 36mp at 6 or 7 fps is no problem with a 2 year old dual processor.

(1) Processing data is not quite linear; (2) stills might be fine, but what about video (the more photosites the sensor has, the more photosites must be processed to downscale the video ... very processor intensive); (3) if it really was this simple, then why haven't we seen a 36MP FF camera from Canon (as they certainly do have the sensor technology for it).

The new generation processors will probably have no problem with 8 or 10 fps at 36mp  so why do you think they need quad processors?

This was directed at the current DiG!C 5+ processor and high-MP sensors.

140
Canon can do dual processors even in a half sized body (7D), ...

And that is the sore thumb ... Canon already needs to dual-configure these little rascals to produce a decent frame rate with 18MP sensors. So to get a decent frame rate with a 36MP sensor they'll need to quad-configure 'em ... 'cause who's gonna buy a 36MP FF camera that can only do 2 frames per second?

Also, can these DiG!C 5+ or 6 processors even be quad-configured?

... and they can do it with modern cores.

True, but the big question is whether Canon has any "modern cores". The very fact that they have not used it in the 1DX tells me that the answer is a very sorry no, they don't.

141
Just once digic5+ is good for at least 180MB/sec (5D3 raws at 6FPS). Given Moore's "law," it would shock me if something like the core logic chip fundamentally precludes higher-resolution cameras.

That's the transfer rate of data, i.e. throughput, of already processed data. What is important is the number of instructions per second that the little guy can do ... and then how many instructions are required to process the data from the sensor's A/D-converter. Not stuff that Canon gives out readily, but it can be deduced from current camera models.

Third Party Manufacturers / Re: New Nikon D800s... Why?
« on: May 29, 2014, 11:57:06 AM »
I don't think the D800s is meant to be a new camera design, but rather (as some have said) an update model with new features added. You know, like we used to get with cars ...

143
I have looked very hard at Canon before I ultimately decided to invest in another system. My conclusion was that Canon cannot really produce a "High-MP" camera (or a decent mirrorless camera) for the very simple reason that the DiG!C processor has hit the wall.

144
all I know is that I look with longing eyes at the the Sony A7R....( and sometimes the D80OE )

and dream up all sorts of ways of how I am going to fit my EF lenses on those  bodies...

Sony A7r + Metabones adapter = QED.

Third Party Manufacturers / Re: FUJIFILM'S latest, X-T1 ?
« on: April 24, 2014, 08:23:51 AM »
One day after making the previous post, the camera store called and said my X-T1 had arrived. I've been playing with it for eight days now (two of which were in pouring rain), using my old Asahi Takumar lenses as my only lenses, i.e. MF all the way. My assessment, seeing that this is a forum dedicated to Canon gear, and you may freely quote me, is simply: "Goodbye Canon."

Your arguments are almost childlike.

Almost? Just almost? I was aiming for completely.  :'(

But seriously, would you take a 1DX to Antarctica for that once-in-a-lifetime, all-important assignment, knowing the camera is not rated for that environment?

Thanks, it really helps.  :)

Good call on seeing what the WR lenses bring. If FUJIFILM brings out a weather-sealed, internal zoom lens in the 50~200mm range (constant f/4 would be sufficient), that'll be my choice.

A friend of mine ditched all his Canon gear in favour of Pentax and is slowly acquiring the WR lenses he needs. It doesn't rain very often here where I live, but when it does he's outside with his Pentax gear taking beautiful pictures while my Canon stuff sits on the shelf.

I ordered the X-T1 about four weeks ago ... they said they'll have stock in about two or three weeks. Then I'm going to try the MF lenses first. I still have all my old Takumar lenses, including a 24mm.

I was thinking of also getting the X-M1 as a carry-everywhere camera, possibly with the 27mm lens. Comments?

When shooting in eagles sub-freezing temps with my 1D X, the LCD stopped working...but the OVF didn't, and I kept on shooting.

The Olympus E-M1 is rated for -10°C (minus ten degrees Celsius); the FUJIFILM X-T1 as well. But the Lord of DSLR's (i.e. the Canon EOS 1D X) is only rated to 0°C .... bwahahahahahahahahahahahahahahahahahaha  ;)

However, a modern SLR with live view is almost exactly the same as a MILC plus a mirror plus an OVF.

No, it is not.

But the problem that many people don't realize is the the Bokeh you lose with APS-C at smaller apertures. ... Basically, the bokeh at f2 on FF is equal to f3.2 on APS-C. ... Then your bokeh is up to f6.4 FF equiv.

Bokeh ... I do not think that word means what you think it means.
