EOS Bodies / Re: 9% larger pixel size on 1D X - how does that translate IQ-wise?

« on: October 18, 2011, 12:22:05 PM »

9% larger pixels seems less significant to me (and I think the numbers back this up) than just the typical generational change in the sensor production technology and other patented elements that are esoteric and do not follow this easy (and I think misleading) apparent mathematical relationship - like improving microlenses, or most importantly improvements in the photon to signal capture chain (including the ADC).

That seems sensible. It's just interesting that a Canon USA engineer chose pixel size as the one thing to highlight, and not all the other aspects.

Well, since the number of pixels got smaller, he sure as heck couldn't highlight that, right?   

I think that's the definition of marketing and PR

Don't expect too much from our main man Chuckie, he's the same guy who said the 50D was two stops better than the 40D at high ISO. 

Ahh... we're only just getting acquainted!

EOS Bodies / 9% larger pixel size on 1D X - how does that translate IQ-wise?

Here's a comparison of relative pixel sizes. Quote from Chuck Westfall (Canon USA Pro Engineering division) via dpreview: (http://www.dpreview.com/articles/5149972341/canon-eos-1d-x-overview)

When asked to for the biggest improvement in the new camera, Westfall stresses that every aspect of the camera has been re-assessed but finally concludes: 'If you had to highlight just one thing, I'd say the sensor. It's a new level for us in terms of image quality.'

'There's a couple of things that we consider when we think about IQ: number one on this sensor is noise. It's clear the noise level is better than in the 1D Mk IV or the 1DS III. The pixel size is larger than in the 1DS III or 5D Mark II (6.95 microns, versus 6.4) and the difference is even more striking compared to the 5.7 micron pixels in the 1D Mark IV. That helps us in terms of light capturing ability and increases the signal to noise ratio. In turn, that does nothing but help the dynamic range of the camera.'

The pixel size is 8.5% larger in the 1D X compared to 1Ds3 or 5Dm2.

Everything else being equal, how does that translate into real-world image quality improvement? (I accept there'll be other factors to consider other than pixel size)

Fantastic call CR guy.. when it really mattered!

EOS Bodies / Great call, CR guy

Fantastic call with the Oct 18th 1D announcement.... you sure got the biggest one of the year right.

That's for your many detractors out there!!!

Keep it up, Craig!

What does a "possible" press release mean?

It's not a real press release? Someone could've made this up?

i might have entered this website around 30 times today waiting for an update that never comes

You may well be in the majority!

Its Monday today, tuesday is apparently the announcement day. I am staggered there are no details leaked already.

Agree. Somewhat odd isn't it, particularly as it's slated for a multi-continent same-day announcement?

It's amazing that some (certainly not all) people read the rumors posted on this site and take them at face value and then proceed to sell a lens or a camera thinking that they will fund the new whatever on release date.  The CR guy is posting based on "best guess" so why would that be enough information to start selling equipment to get a jump on buying "vapor equipment".  I don't understand. 

Good point, very true indeed.  However, one of the reasons people come to this site is to hear about rumors or leaked info about upcoming gear and the implied value is that CR Guy has knowledge of the industry and contacts that are better than us mere mortals.  On that basis we have an expectation that CR Guy vets the rumors, can spot the crap, can look for corroboration, and wouldn't post nonsense without saying so... i.e. putting a CR1 or even 0 rating on it.

In the case of this "Sept 22 pro product announcement" I think the ball was dropped a little bit and CR Guy has owned up to that by posting an apology and commenting that he'll be more careful about posting anything from DigitalREV.  Props for that.

Other reasons some people might come to this site are to talk about gear with fellow gear heads and to be entertained by bold and ridiculous claims by certain members.  And on that point, this thread certainly delivered! 

To CR guy's credit, I've been following this site for at least 6 months, and this is the first time (as far as I can recall) a rumour about an announcement hasn't materialised (in terms of presence/absence of one, not of the content). This speaks volumes, as you'd expect any other run-of-the-mill rumours site to be filled with many more false dawns.

Meanwhile, the only new products on the Canon Japan home page from today are a couple of new calculators, so I guess that must have been it.

Calculators? Lol! Really scrapping the bottom of the barrel, aren't we?

Any word about how big of a rebate?

And does the end date of the USA rebate suggest that any DSLR announcement will more likely happen after?

Software & Accessories / Re: What raincover solution do you use?

« on: September 21, 2011, 06:20:49 PM »

I posed this question too a while back, and got some useful responses. http://www.canonrumors.com/forum/index.php/topic,1184.msg16117.html#msg16117

Blower idea is great for keeping the lens clear of large droplets.

I used the Op/Tech rain cover on my 7D (upgraded to this since my post) - it was OK. Sort of did the job - there's an opening on the rear end of the cover which is supposed to stay on the camera once you have the eyepiece clipped in place over it. Unfortunately, my eyepiece would not 'click' in place, kept falling off, and thus it all become somewhat annoying.  Actually, it was more than annoying. As a last resort (I was already in the midst of the water spray), I decided not to clip the rear opening of the cover under the eyepiece, i.e. I ended up with a small mobile unsealed opening in the rear cover and a few drops of water got to the outside of the camera body. Low and behold, I had an error message on my 7D for over an hour after that. It's been fine for the past 2-3 weeks since - guess it dried out!

So if you want to use the Op/Tech, make sure you spend more time than I did tweaking it and making sure it fits under the eyepiece and the latter clicks in place.

Maybe the trash bag would be better after all!

When will this be available?
