So, in summary: a new Canon sensor with virtually no improvement in DR and low ISO performance, even after several years of stagnation (T2i, T3i, T4i, T5i all pretty much the same) and at least a couple years being significantly behind the competition. Just another sign, IMHO, that they simply don't care much about the landscape niche and are content marketing primarily to other segments.

Preparations for switching to a D600 are underway for this Canon loyalist since the 300D. It wouldn't surprise me at all if landscapers on this side of the fence who hold out another 2-3 years for the 6D/5D3 successors are ultimately greeted with a similar fate. Based on the responses in this thread, and many similar ones here recently, the lion's share of Canon users simply don't care much about DR, regardless of how far behind the pack they fall and for how long.

I think they would be praising the DR if the shoe was on the other foot. If the Canon sensor was the clear leader in DR, we would be seeing it as one of the major benefits of Canon. Just the nature of the human beast.

I thought we were just talking about image quality here. I found the image quality from the D800 was much better than what I got our of the 5D2. Now, this is a base ISO's which is where I shoot. Also, at base ISO, the image quality from the 5D3 and 5D2 are basically identical...did that test as well.

Better where??? you have pictures to prove it? download raw files from here

Yeah, "LOL"... imagine that, the need to expose for highlights in a scene with large DR! I mean, that only happens like every other scene you encounter outdoors, particularly with landscapes... and quite often during the best lighting/weather conditions.

I truly do not understand why so many people here poo-poo the value of DR. When it's Canon with 25 stops vs. Nikon with 27, rather than 10 vs. 14 or whatever we have now, then maybe I'll start buying into your POV.

Quite right. I must say that we forum members are often guilty of over-the-top hyperbole. Suggesting that the image quality of the D800 is "much better" than the 5D II or III is a bit too much. If a camera has "much better" image quality then that quality chasm should be readily apparent on photography sharing sites like Flickr. In a real world setting like that do D800 photos really stand out from 5D II photos as much better? I don't see it. But, I do see an apparent image quality differential (on such sites) between modern DSLRs and Point and Shoot cameras. In fact I can see more of an image quality variance between full-frame (any brand) and crop-frame (any brand) than between D800 and 5D II or III.

I loved having and shooting the D800 - it's a superb camera and I am absolutely a D800 fan. But, I'm also a big fan of my 5D III; it's my favorite camera I've ever owned/used....until recently. ;)

No need to LOL, there is a fix for that and is to use GND filters, you guys make it sound like canon is worthless for landscapes which is a big lie..

I don't get that either. Absolute brand loyalism I guess. :) I find workarounds, but no doubt: I wish my 5D III would give me more recoverable usable shadow detail than it does.

GND only really works when your transition zone is basically a straight line. How do you deal with say shooting a waterfall in dense foliage along with the sky peering through some tall cedars? There is no GND filter in this world that will rescue your shot...the sky will be blown out.

Not worthless...in fact I use a 5D2 for my landscapes. But Canon is definately behind Nikon when it comes to landscapes...and that is what we are talking about. Please don't take it to extremes...no one is claiming worthless.

Well there I would probably bracket my shots, no big deal D800 is a great camera also and if I did buy one I would get the E version, but owning dual systems would be expensive.

Bracket becomes a pain as there is usually a wind from the waterfalls and the trees and bushes are all moving between shots. Overall, to get quality, crisp images, bracketing is very challenging for many occasions.

If you could expose for the sky and lift the shadows all from one shot, that would be the best, and this is where the D800 shines.

If that's the case I would not add the sky in my image, but I do get where the DR would be useful, BTW I see you are from Vancouver BC, I was born in Haney but was raised in Marysville wash;)

And there you go.. the equipment is affecting your photography.. negatively. You have to alter your image... settle, as it were. And they say that equipment doesn't matter? ;)

This. Even aside from moving subjects, I've found that if I don't use a remote shutter release with AEB, I very often end up having tiny movement between frames from my finger pushing the shutter button. And this is on a heavy Manfrotto tripod.

So essentially, if your sensor can't handle the DR, you have two options:

1. Bracket. Requires a tripod, non-moving subjects, and setting up a remote shutter release mechanism.

2. GND filters.

Both options take too long to set up, for most of what I'm trying to do, and the latter is also very cumbersome and limiting in other ways.

To act as if having the DR to spare in your sensor to begin with is some trivial feature that only gearheads care about just doesn't make sense to me.

Truth be told in the shadows!! :lol: A gnd is nice but, it doesn't solve every high DR scene.

You should buy a second system. It's not that expensive.
