EOS Bodies / Re: Canon 6D Under-Exposing?
« on: December 05, 2012, 02:18:19 PM »
These shots confirm what I've noticed with other 6D test shots: that the 6D has a tendency to 'expose to the left'.
Reminds of my 40D, which does the exact same thing.

Not sure why Canon decided to implement the 6D exposure like that but I can tell for sure that this was their intent.
Overall, nothing to worry about. This is not a 'bug' but a feature ;).

EOS Bodies / Re: Canon 6D vs 5D MKII (Focusing?)

My final words are.. the center point from the Canon 6D might be better for accuracy from any Canon camera ever build.. believe me, this thing is very powerful..
Hmm. LensRentals did a controlled test and the results don't support your enthusiasm.
In terms of AF accuracy, the 6D is closer to the 5DII than the 1DX/5DIII.

EOS Bodies / Re: 6D Likely Price Trend

The price will drop eventually.
The 6D is not overpriced as the 5DIII, though, so I wouldn't expect a very quick price drop.
More like the normal, gradual drop over the product lifecycle.

IMO, by the end Q1 next year it will be clear what the demand is for the 6D.
The price will be adjusted if necessary (by $100-200 max) and then will stay stable until the holiday season.
After that, it’s anybody’s guess what the price will be.

Hard to believe that the 7DII will be more expensive than the 6D.

As per Canon's nomenclature, the 6D is a more premium model than the 7D.
So, unless Canon's marketing guys are out of wack, the 7DII won't be more expensive.

As I said in a previous post, I'm expecting that the 7DII price will remain the same as the 7D at introduction ($1699).
This is based on the expectation that the 7DII will be a warmed-over 7D but with a better sensor.

I could be wrong, of course, and the 7DII might get a price as high as the 6D.
Certainly not higher (again, unless Canon's marketing department has gone out of control).

Overall, it looks like the 6D will get a higher DxO score than the 5DIII when DxO does their thing.

This is one of those weird things that I don't understand about Canon:
The cheaper 7D has a better AF system than the 6D, which in turn has a better sensor than the (much) more expensive 5DIII.
Why would someone do these things ???. Wouldn't it make more sense if the more expensive product is also the better one?

Here is what you asked for: iso3200 and 6400 comparisons

Many thanks.

There's no discernible difference At ISO-3200 but at ISO-6400 the 6D seems a trace better.
Look at the black patches at the bottom of the frame to see the difference (between the circuit board and the grey card).

One thing missing....what is your expected/suggested price for the 7D MKII?

$1699, same as the 7D at introduction.

they will not trump the 5d3 so res is below 22, noise is terrible as usually with crop.

Agree about the resolution. I believe the 7DII will have 20mp.

Not sure about the noise, though.
As previous rumors suggested, the 7DII might indeed use newer sensor tech.
If that's the case, I'm expecting ISO performance on par with the 1DIV.

In general, all those recent 7DII rumors suggest a 1DIV ... at a 7D price.
Hmm, don't know about that.

Since wishlists and speculations are fun, here is what I think we can expect from the 7DII:

  • Sensor: a better 20mp sensor with ISO on par with the 1DIV.
    Positive surprise: ISO is even better.

  • Frame rate: remains the same at 8fps.
    Positive surprise: maybe 8.5fps or 9fps.

  • AF system: same as on the 7D but a tad snappier.
    Positive surprise: more AF points (maybe 27 or 33; certainly not 61).

Overall, the 7DII will be a warmed-over 7D but with a better sensor and other minor improvements.
The 7DII will be like the 1DIV ... but only in image quality.

Other than that, it will remain a 7D: an excellent offering but not a 1D series.

There, you heard it here first  8).

Opened with capture one 7.0.1 (preliminary support)

Many thanks.
How about the same but both the 6D and 5DIII at ISO-6400.

There's no doubt that the 6D is better than the 5DIII at super high ISOs.
I'm also interested to find out what 'happens' at ISO-6400.

EOS Bodies / Re: First Round of EOS 7D Mark II Specs [CR1]

from the B&H link:
"the DIGIC 5+ processor also delivers overall speed and power to the 6D and utilizes dual 4-channel A/D converter"

Looks like the same 8-channel setup to me. At the minimum, I'm betting on dual DIGIC 5 (non '+').

According to Canon CPN Europe, it's a four-channel readout. See the 'Key technologies' section here: 

But you might be right, after all, that both the 6D and 5DIII have an 8-channel readout.

In any case, if you've seen the size of the Digic 5+, you know that Canon is not going to use two of these in a non-1DX body.

The 1D X has dual Digic 5+, so presumably that's needed for 18 MP at 14 fps.  Guess what?  18.1 MP x 14 fps = 253.4 MP/s, and that value divided by the rumored 24.2 MP equals 10.5 fps, very close to the rumored 10.2 fps

Right. I'm sure that this is how this lame 7DII rumor came into being in the first place.

But the 7DII will not have dual Digics. Take my word for it.
It will have a single Digic 5+, same as the 5DIII and the 6D.

Here's another math that you can do:
The 1DX has two Digic 5+ processors and a 16-channel readout (official specs).
And the 5DIII has a single Digic 5+ and an 8-channel readout (again, official specs).
Therefore, it can be concluded that the Digic 5+ processor has an 8-channel readout.

Also, the 6D is capable of 20mp @4.5fps with a single Digic 5+ ... and just 4 readout channels (again, official specs).
This puts the throughput of the Digic 5+ processor at 20*4.5/4 = 22.5 MP/s per channel.
That's a throughput of 180 MP/s total for all 8 channels on the Digic 5+ processor.

Realistically, Canon will not go over 10fps in 7DII and will not put dual Digics in it.
So, I'd say that the 7DII will be spec'd anywhere between 16mp @10fs and 22mp @8fps ... with a single Digic 5+.

I'd prefer if Canon puts 16mp/10fps in the 7DII but it's more likely that they will go for 20mp/8fps.

One thing is certain, though: the dual Digic V spec is fake and this whole 7DII rumor is a lame [CR0] rumor.

This spec is enough to tell that the rumor is fake.

The Digic 5+ processor is a dual-core (quad-core?) Digic.
So, no need to put two Digic 5s in a camera when a single Digic 5+ will do.

This is [CR0].

Canon have an inflated price structure ...


Canon released very good products this year, actually.
But most (all?) of them are overpriced.

EOS Bodies / Re: Next year's APS-C vs. this year's FF
« on: November 21, 2012, 11:04:49 PM »
Ditto if the new 7D as an APS-C camera had IQ = to the 1Dmk4 it would be pretty awesome.
However I would not hold my breath for this being the case

1DIV-level of performance shouldn't be all that difficult to achieve with a 1.6x sensor made on a newer tech.
Provided that MPs are kept in check, of course.

The question is, what will Canon do with the 7D successor.
Will they go for a more pro-oriented body or a more general-purpose body?

If the former, I could see the 7DII using an improved 16-18mp sensor, which I'm sure will match the 1DIV in image quality.

But Canon might as well decide to crank up the megapixels.
In that case, it's hard to tell if the 7D successor will be even called 7DII  :-*.

« on: November 21, 2012, 07:04:50 PM »
Question: If Canon does implement this tech in a 7D.2, could that APS-C camera produce lower noise at low ISO than current FF cameras?

Even if the 7DII sensor is made on the rumored new tech, the best we can hope for is performance similar to the 1DIV and 5DII. 
Just consider that for 1 stop better ISO performance, the sensor needs to be 2x better, basically.
