Bingo. Thank you. I caught that same line myself this morning and wondered. Not long ago I read a post from someone at CR in the forums talking about how if this was indeed an upscaled 7D2, that mathematically you should see (if memory serves) a 1 to 2 stop uptick in useable shadow detail. Now I don't what what "traditional methods" vs current methods means in the grand scheme, but if the 5D3 gave us 11 stops and this new machine gives us closer to 12-13, then ok. IF WE ALL START HAMMERING AWAY about adding a Dual ISO function built into the firmware from Canon (as opposed to a ML hack) then we could easily see 14-15 on a 50MP monster like this. I've already posted it on CPS Facebook page. I suggest we all do the same. It seems so easy a thing to implement between now and June....Show more →
See, that's the way to do it! Not calling for a boycott. Instead, thinking of a positive and brainy way to assist your vision becoming a reality. You'll sure get more agreement moving in that direction. Thank you!

Oh, thanks for the correction. I thought most countries with VATs required businesses to always quote their prices with the VAT included. Is that not the case in Canada?
Not the case north of the 49th. AFAIK, that vat rule applies tomthe uk and possibly Aus.

By DxO's calculation, doubling the resolution yields a 1/2 stop improvement in dynamic range for sensors of equal technology/noise (source).

The lens is very intriguing - can't wait to see how it performs.
I'm just not sure about the new body at this point in time. I'm pretty satisfied with the 5D3. The excitation factor isn't there for me, but there's a good chance that it'll grow over time.
I am looking forward to seeing how it performs in the real world. Bring on the RAW images (and a suitable converter).

Though I mentioned this in another thread... I am repeating it here to get an opinion of other members and consider the possibility of fps improvement in firmware (as suggested by some)
Look at the section drive system -> maximum burst for 5Ds and 5Ds R. Both have a maximum of 14 RAW files independent of the crop.
Though processed file sizes are different between the two models due to different level of sharpness at image capture (you can see jpgs). The core RAW data from the sensor will be of the same size. My guess based on that is Its not the processing power (Dual DiGIC 6) that is limiting the fps. It is the sensor readout (the same area is also the reason for poor low ISO DR). I do not think Canon created a way to read out only a part of the sensor when they designed it. My guess is their column ADCs can only read all of the data from all rows and not selectively. This in a way imposes a limitation of having to read out the whole sensor data and then discard the portions not needed. Since Canon is doing this crop modes for the first time, i think they did not plan for it ahead of time when designing the sensor to make it possible to do selective readout. I believe, the whole "Crop Modes" is an after thought based on some customer interactions and is just something for their marketing material purpose only.

As it pours down very hard rain here in CA Bay area, I am reminded of shooting in the rain in AK the last two summers and how my 1ds3 was OK but my 7d crapped out for a day till it dried out overnight,
.
Wondering if this 5dsR has the extra weatherproofing just put into the 7d2? Can not find any info about this!

Doesn't seem like it. If the have done it they would have made some fuss about it and touted it. From what has been mentioned in the canon material it looks like a 5D3 body with new tripod base plate, that's all. It did not receive any body improvements like the controller dial etc from 7D2.
The 11mm f/5.6 sample looks a tad soft for the final 1/3 of the frame at least compared to the very sharp center but it sharpens up brilliantly @ f/11. The 24mm sample has sharp edges even at f/5.6. Very impressive.

I will own a 11-24 soon - If anyone has the numbers would you be able to help me calcualte if the the FOV of a 11 would compensate for the Shift adjustments on my 17mm? between that and the 16-35 F4 IS, I could afford this lens in a heart beat!
As long as the 11 gives me a cropable 17mm with shift correction, I think Id jump out of the 17 TSE. I dont use the Shift enough to make it worth it.

I do not see any f/11 images all are f/5.6
Oops you're right, I confused the focal length text for the aperture. Odd how the first 11mm image has soft edges whereas the second 11mm image does not (1st image on left vs 3rd image).

It's not the readout being too slow that is the problem. It's that it's very fast and the chip must run fast because the number of readouts is so low (just to clarify). There could probably be a slow readout mode with more DR. (just random, not really what you are talking about I know).
And the crop mode will have a point, almost certainly. Same reason as the crop mode on the D800--no one really cares about the tiny fps gain or the smaller file size, computing power is cheap. But you gain an uber buffer! If Canon is doing it right the crop modes should have a pretty nice buffer, adding versatility.

The 11 mm shot had flare towards the center, just like my 17TSE. Got to watch those bulbous front elements.
