Is a photograph an accurate depiction of a scene, or is it art and to be manipulated to emphasize a feeling or a concept? Or is it both or is it neither?

remember folks..... we are talking about a FF camera with the same pixel size as the 7D2. It will have very similar IQ to the 7D2. It will have very similar ISO performance to the 7D2.

You can't have the megapixel count of tiny pixels and the performance of large pixels. You can have one or the other... or a compromise. You can't have both. The 6D, 5D3, and 1DX will be superior in low light.

That's why I think it will be a new series, not an update of an existing series.

I bough the 6D to be a low light camera.  I do not care if it has the ISO performance of the 7D II.  I want a very weak to non-existent AA filter High MP camera for landscape.  I would like an articulating screen because I to most Landscape on a tripod in live view.  It is very helpful be able to adjust the.   screen to a better viewing angle.

Yes tiny pixels = miserable ISO performance. 

I really do not see them replacing the 5D III for 2 more years.  As an event camera what is wrong with the 5D III?  I really do not see anything.

The 5D3 has to be about the best general purpose FF camera out there.... I can't see Canon messing around with it.... I really doubt that a new high megapixel camera would be a 5D4

You're off the rails.  Just making the sensor bigger - with the same sized pixels - will improve high ISO performance by 1 1/3 stops.

Oh, and in-general, smaller pixels perform better at all ISOs than larger ones.  The only exception is very extreme high-ISOs.

I wonder how the sarcasm impaired will act?

Thank you very much for the links (especially the first two).

I have found the following interesting link:

http://www.canonwatch.com/eos-5d-mark-iii-hacked-anti-aliasing-filter-removed-more-sharpness/

Wow - what a horrid test.  They lighting is entirely different between the two shots.

The exposure is different, the two shots are not framed the same and there is a huge difference in how clear the air is...

nothing to see here.... move along.... move along....

This is all beside the point anyway, as all it takes is ONE step, or even to stand up or start standing up, and your target could flee. Birds of the heron family in particular, for example, are extremely skittish birds. If you manage to get close enough to get a decent shot at all, then smaller pixels are going to be a bigger friend to you than getting closer. I can't count how many times just seeing my head barely rise over the top of a ridge was enough to make every heron and egret in the area fly off. Hawks are similar...they can be perfectly content with you sitting there watching them if your not moving. The moment you stand up, they'll leap off their perch and fly right over your head! :P (I've had this happen a few times.) Deer are content to get right up in your face so long as your sitting on the ground...stand up, they'll dance around and huff a few times, then wander off. Outside of wearing a ghillie suit, even in camo deer will spot me. If I stand up, they at the very least stand rigid and take notice. Start moving towards them, and they will often bolt.

It's not necessarily always as easy as taking a few steps closer to your target.

I have a startling inability to walk on water so zooming with my feet rarely works.....

The worst failure is not a catastrophic failure, it is subtle damage.

With a catastrophic failure , you know it, stop using the camera, and grab a backup.... With a subtle failure you go out and shoot an entire event, come home, and find that the focus is a bit off on every single picture and you have garbage.

Can you risk it? I'd send it back to be checked.


So you have been there and done that, too?
Did it in my daughter's wedding. Flash just didn't.
Luckily there was the Midnight Sun but still I felt like an idiot.

Been there, done that....a dropped lens...

There was a diagonal line through the center of the frame that was in focus... everything under it and over it was out of focus.... when I checked in the field by zooming in to the center in live view, it looked good, but when I got home and looked on the monitor, everything was garbage....

BTW, anyone want to buy an 18-200 not-quite-so superzoom?

Too true...


LOVE IT!

Mine just glide down from an 80 foot oak tree that's about 30 feet away.....

Some people are excited, some are denouncing this. One thing is for certain: this is a huge buzz that will not just affect Canon shooters but shake up the market for other brands as well. Studio/landscape shooters will be flocking to this 50MP body if all goes well, and suddenly Nikon and Sony will have to have something like this.

I think we all knew it was coming.... it was just a matter of time. With Canon being so conservative, it means waiting until they can do it right....

Ten years ago we were at 6 or 8 megapixels and high ISO meant 3200.... Now look at the 7D2 or the 1DX... they are a LOT closer to any new 50 megapixel camera that the cameras of 10 years ago.... probably 95 percent of the way there.... although it sounds like a big deal, going from a 7D2 to a 50 megapixel FF camera is really just a small increment... just a matter of scaling a sensor yet using the same tried and true geometry.

those are really nice shots, the red squirrels we have here in the u.s. don't have those comical ears. they look more annoyed than suprised but they are still entertaining to shoot.

I had this (http://www.canonrumors.com/forum/index.php?topic=12203.msg262313#msg262313) posted last year. I was also guessing about the long tufts then in March, but in discussing it we came to the conclusion that it's part of the winter coat.

From the linked thread:

... a Red squirrel (Sciurus vulgaris)

The American red squirrel is a different genus and species: Tamiasciurus hudsonicus.  I haven't seen ear tufts like that here, in any season.

*nods* Indeed so. From the looks of it Mario and I have the same variant in Belgium and here in Sweden. Met a couple from New York who were here in August, and they wondered why I was so interested in the squirrels here. To them they were more of a "pest", and I think that goes for both the grey and the red squirrels. Ours (the red squirrel) have a slightly better reputation and behaviour, and it wins the sexy ear tuft award any winter.
I have red, black, grey, and flying squirrels here...... you can't make a bird feeder flying squirrel proof....

A Canon sensor with the same technology 7D Mark II, but "stretched" up to 50 megapixel, would get much better score when DXO down convert to 8 megapixel, and the theoretical DR would overcome any camera that Canon has released to date.

nope, that's not how DR from Canon sensors scales, it's about the same at any scale
I don't think he is talking about real scaling..... he specifically said DXO down convert, which increases DR on non-Canon sensors and decreases it with Canon sensors :)

Increased resolution causes increased DR?   ???

It does if you believe in DXO and that you can "normalize" photos....

Take a 32 megapixel image shot with 12 stops of DR

Normalize it to 16Mpixels and 13 stops...
or 8Mpixels and 14 stops...

Then you say how much better it is than another camera which only has a native DR of 12 1/2 stops....

Once you can do that, you are ready to buy snake oil from DXO...

Ask yourself this question.  If an AA filter did nothing but decrease image quality, why would camera makes put it into a camera thereby costing themselves money and buying nothing but lower image quality rankings?

The answer is simple - they don't.  An expensive camera like the 7DII (which has the same size pixels as a hypothetical 50MP full-frame camera) has an AA filter because it is necessary to get the best possible image quality.

OK Lee..... this is your last warning about using common sense and logic in an emotional argument :)

and seriously, I agree!
