EOS Bodies / Re: Canon 7D: Buy now or wait?
« on: August 09, 2012, 11:44:29 AM »
What new camera are you afraid of appearing?

7D Mark II? Nope.
6D? Nope - well even if it is announced, you won't be able to buy it this year.
70D? Maybe but nobody really knows for sure what its specs will be.

EOS Bodies / Re: I doubt they would miss Photokina
« on: August 09, 2012, 11:39:08 AM »
If Canon has the product ready to announce, it does not make sense that they would skip Photokina with it.   The Nikon D600 will be out there; it would make sense for Canon to be able to talk about their lower-priced FF as well --- unless the Nikon D600 will smoke the Canon 6D so completely that Canon wants to avoid putting a spotlight on it.

I think the D600 will be better spec'd, but the 6D (or whatever it will be called) should be a good camera as well.  It just doesn't make sense for Canon to take a walk on Photokina as far as this new model is concerned, even allowing for the declining importance of trade shows in the age of the internet.

Two thoughts: maybe the real situation is that the announcement will be at or near Photokina, but the rumor source meant to say that availability will be in October -- that Canon is ready to put this camera in the pipeline quickly.   (That should give it a big advantage over the D600 -- good luck getting one before mid-2013!)

or...  There is something even bigger to announce that Canon wants to have the full spotlight!    A new 70D with new sensor technology, perhaps?  :)

though canon doesn't always put things "in the pipeline" quickly. Look at the new mirror-less M camera. It won't be out until October. This being said I hope the new "6D" DOES come out in October like this rumor stated...

With Canon's recent delivery reliability, we'll be lucky to see it before Christmas if it has an October announcement.

Actually, that's my bet for the October timeline: if Canon announce at Photokina, then people will expect it before Christmas and will get upset if they can't have it and will likely defect to Nikon for the holiday season buying.

By announcing in October (my bet will be on mid to late October), it'll be fresh enough in people's mind that as the holiday buying season starts a few weeks later, people will wait for the 6D rather than give up on Canon and go with the D800.

Thus Canon can't deliver it before the end of the year but if they don't announce something, then people will jump ship in the leadup to Christmas.

Actually, no. A 20 year-old-intern would have included a "lol" somewhere and other crap. The person that wrote this review has been writing camera reviews for years for a newspaper and is old enough to have used film SLRs.

.
That rather florid copy was probably written by a 20-year-old intern who fancies himself a "photojournalist."


From a local newspaper:

Verdict: This is a wonderful camera. If you hvae Canon lenses and want to move into the blissful realm of full-frame capture, then the 5D Mk III is for you. But the MkII is just as good for stills and costs $1600 less. If you already have a 5D Mk II (as we do), there is no pressing reason to upgrade. If you are starting from scratch with nothing invested in lenses and accessories, then look at the Nikon D800. It has superior ergonomics, a more luxurious feel and higher resolution sensor, and produces uncompressed video. And it is several hundred dollars cheaper.[/u]

His chart claims that a D3100 has 0.0 read noise! 
That should give a clue as to accuracy / credability.

Why, you have your own data from doing the same measurement with a D3100 sensor that contradicts it?
Or you have another source that you can cite to show that it is wrong?

No, I didn't think so.

Is one necessary? If I told you that I dropped a penny and a bowling ball off the Leaning Tower of Pisa, and both of them flew straight up into the stratosphere, would you need a source to prove I was wrong?  0.0 read noise is an electronic impossibility (if it had stated below the LLOQ, or something similar, fine, but not zero).

First, "0.0" is not "0". Second, it could mean LLOQ, but I don't know enough about the method, etc.

Generally speaking, if you want to criticise someone else's results of a scientific method then you do so by doing your own experiments that prove your point. And yes, I'm willing to bet that the method DxO use to generate the raw numbers that goes into those calculations and the method of arriving at the calculations in that table is a lot more scientific than the process of saying "That 0.0 is wrong and because that 0.0 is wrong all other results lack credibility."

Further, all of the results (except for that line) seem completely reasonable which tends to suggest that there is more than fiction behind them. If it was Ken Rockwell posting this information then I'd be extraordinarily suspicious. But it isn't and more to the point, the page is free of ads so quite clearly there's no need by the author to generate lots of page views by creating sensationalist content.

Finally, as the "About" page says (http://www.sensorgen.info/Calculations.html), all of the calculations are based on DxO data. If the "0.0" seems outrageous then you're free to download the data for yourself and see if the published methodology confirms that "0.0" is correct (or not) and also to contact DxO and challenge them on the accuracy of the data for the Nikon D3100 or even start threads all over the Internet about how the true extent of Nikon fanboy-ism at DxO is revealed by results that are obviously bogus for the D3100.

How about this post regarding a big megapixel camera.....


http://www.canonwatch.com/rumor-canons-medium-format-camera-tidbits-and-maybe-no-pro-i/


Medium format camera using EF lens....

Sure, if you use the EF-17 TS/E.

Otherwise none of the lenses create a big enough circle of light to cover such a sensor.

No, I didn't think so.

There's a whole bunch of very information available in those tables if you take the time to read them. For example, they generally agree with people saying that the 5D3 is slightly less noisy than the 5D2 but not significantly so.

I think the D800 has Q.E. of over 55%, which is one of the best on the market.

See this thread:

This guy uses the raw sensor data from DxO (remember, they're worthless!) to create some different measurements:

http://www.sensorgen.info/

ModelQEMin Read Noise (e-)Max Saturation capacity (e-)
5D2333.264600
5D3492.467531
D800562.644972

This table also makes the 60D better than the 50D and 7D.

I just re-read the posting and it says...

"Both comments mention an announcement sooner than later."

Canon has been big on announcements this year and low on delivery. Remember the 1DC and C500 announcements? Well they're not even products yet and they were months ago.

And then there's the 24-70 MkII which was announced and... does anyone have it yet?

So even if Canon did announce it tomorrow, it would be March 2013 before there were any rumors of it actually being in stores.

Now the D800 exists so that is now the yard stick by which every other DSLR of that form factor will be measured when it comes to IQ.



I find it strange that one of Nikons biggest fanboys says  "The Canon EOS 5D Mark III is the world's best digital SLR. It easily lets us create smooth, clean, beautiful and colorful images in any sort of light."-Ken Rockwell

He isn't a Nikon Fanboy, he just writes whatever will get people to visit his website and paste his urls on other websites for people to click on.

True, Im not denying that. But D800 was announced on 7th of February and 5D Mk III month later. What Im trying to say is that 5D Mk III development could have ended months before D800 announcement so no possibility to respond.

I think both cameras were finished in terms of hardware design at least 6 months before they were released, possibly longer. That is to say that Canon was committed to the 5D Mark III in its current form from probably a year ago now.

I think that Canon is aware of DR/high MPx problem

High MPx, yes. DR problem, I wouldn't be so sure of that Canon recognising that problem if I were you.

If the leaked image of the D600 LCD panel is anything to go by then it will have DPS, 51 point focus,  WiFi support and HDR.

How many of those features will be in the next FF Canon DSLR?

Lots of nice features there.

as far as I can remember, complanis about 5D Mk II were mainly in regard of its AF and maybe slow burst rate - nothing about not enough reoslution and dynamic range - so Canon responded to complains upgraded AF to best and gived us 6 fps and all-in-all better all-around camera

That was before the D800 existed.

Now the D800 exists so that is now the yard stick by which every other DSLR of that form factor will be measured when it comes to IQ.

The D800 ushered in a new era of DSLR with its sensor just as the 10D with its price and the 5DMarkII did with HD video.
