EOS Bodies - For Stills / Re: How to differentiate crop vs. FF

What your test shows is that the later generation is better. No surprise there.
The 20D and the 5D were the same generation, and the T2i was really not much better per unit of sensor area, except for the higher pixel count.

I'm sure the better light-gathering capability of the T2i's pixels is irrelevant...at least insofar as ignoring it helps support your conclusion.

Neuro, who used to own the 5D MkII and 7D, sold the 7D after getting his 1DX and doing similar tests, AlanF used to categorically state the difference was massive until he got his 5D MkIII and on and on............

I initially compared the 7D to the 5DII, and came to the same conclusion you have – APS-C image compared to FF image cropped to APS-C FoV, the APS-C has slightly more detail and slightly more noise, and one can be traded for the other so in practice, the only difference is in the MP of the resulting image, and if ~8 MP is sufficient for your output there's no advantage to using the crop body from a sensor IQ standpoint.  Still, the 7D offered significant advantages in other areas - AF, frame rate, weather sealing, etc.  The 1D X obviated all of those advantages, so I sold the 7D.

What I am saying is 'in same generation sensors the differences between a crop camera, and cropping a ff camera to get the same fov
Baloney.  I specifically went out and proved you wrong

So, he states same generation sensors and cropping the FF sensor to the crop FoV, and you prove him wrong by showing (jugding by the image titles and pixel dimensions) a comparison between cameras from 2004, 2005, and 2010 (a 5-6 year technology gap), and upscaling some of the images. 

That was a complete fail.  Care to try again?

Third Party Manufacturers / Re: Woe and Pathos in the Sigma 50 Art?

Now I'm wishing Canon had a dock!!!
I imagine that soon all the lens manufacturers will have some connection, either a dock or a built in USB.  Or maybe just a pass through using the camera hooked up to the computer. 

But in any case a lens to computer link may become more common in the future.

Likely true for 3rd party lenses.  For OEM lenses, connection via the body makes more sense, IMO.  In the case of Canon, you can currently update lens firmware via the body (tethered or by loading the lens firmware on a memory card).

If you have a 1Dx getting a 7D MkII for 'focal length limited situations' will almost certainly make little sense...

I'm certainly not planning to get a 7DII, it really offers no meaningful advantage for me.

In spite of the naysayers, this will be a very useful technology for anyone shooting with a mix of fast primes and slower lenses, and innovative of Canon to work toward a dSLR implementation of the technology.

So are you saying that there is no such thing as "pro grade gear"?
My point is that there is, and it is up to the manufacturer to label it as such.

There is higher end gear and lower end gear.  Calling the higher end gear 'pro grade' is just a marketing tactic used by some manufacturers to label their higher end stuff.  As pointed out earlier, car makers use letters or numbers in the naming scheme for differentiation...that really has nothing to do with professional drivers.  "Pro" gear is just an arbitrary marketing designation, it doesn't connote anything about the intended use.

EOS Bodies / Re: Multilayer Sensors are Coming From Canon [CR2]

In the past, all GPUs were off-CPU.  Now they are 90% on-CPU.  In the past, 100% of computers were desktops.  Now, they are more than 70% laptops.

Lightroom and Photoshop have mobile versions for the iPad.  From a processing standpoint, that's about doing more with less hardware, not better leveraging the fastest hardware.

On the other hand, the typical non-pro (*not* CR readers!) would not understand most of the features ("Mirror lockup? Eh?"), the features wouldn't be part of their purchase criteria, and they wouldn't pay up for them.

My Rebel T1i had mirror lockup.  Apparently I had a pro camera way back then.   ;)

EDIT:  Canon omitted that feature from the EOS M, and Sony left it out of the a7 series.  I guess that makes all of those consumer cameras.   :P

I've been curious for some time why Lightroom doesn't make extensive use of the capabilities of my video cards...if games can render vastly more complex scenes 60 to 120 times per second using a GPU, Lightroom should be able to do what it does on a 5-layer RAW quicker than it renders a bayer RAW now.

Agreed.  DxO Optics Pro used to be rather slow at displaying images at 100% on my Mac, and even filmstrip thumbnails weren't very fast.  A version back (IIRC), they added GPU acceleration and it sped the rendering up significantly.

Neuroanatomist, here's a "pro" microscope for you: http://phys.org/news/2013-01-three-photon-microscopy-biological-imaging.html
Image the full thickness of a live mouse's cortex! But you must have seen this - I put it up here for the entertainment of other geeks.

Cool stuff!

Kinda my point, though...where is it called 'pro'?  I have scopes costing from $1,000 to $800,000 – none of them are called 'pro microscopes'.   ;)

Must be time to trade-up Dr Neuro...

I was wrong, it seems...

I had no idea pro microscopes were so cheap compared to my systems!!   ;D

Generally speaking, a manufacturers top of the range product is aimed at pros. Take knives, pans, laptops (the business lines), and I presume microscopes etc.

My Calphalon Commercial cookware was bought at Macy's, and my Wusthof pro knives came from Williams-Sonoma...not a restaurant supplier.  I've never seen a 'pro' microscope.  General Motors ran a marketing campaign for their Professional Grade trucks...I know a few people who use them to commute to their professional office jobs.

The top end is aimed at people who are willing and able to pay the higher price.  "Pro" is purely a marketing distinction.

Just look at cars. All Mercedes-Benz will get you from a to b, but the S series may do it in a lot more comfort and style than the lowly C series.

So the S series is for professional drivers?  Why are so many taxi cabs Toyotas and Fords, and so many limos Lincolns and Chryslers? 

However, Mercedes does make vehicles for professional drivers.  Here's one:   ;)
