For tripod landscapes I can't see any disadvantage to an A7 or A7R. AF speed doesn't matter. EVF lets you judge exposure/histogram before shooting. Tilt screen is useful if your tripod is down low. What's the problem?

Hanging a big zoom lens on the front whilst tripod mounted is what the problem is.

A large lens will typically have its own tripod ring and foot. The EF adapters I've looked at also have a tripod foot so that the adapter bears the lens weight (for lenses too small to warrant a tripod ring).

How could you not know this? Hmmm...This is hilarious and reads like someone who has never actually taken a photograph. Do you actually go out and take any landscape photographs or are you just an Internet arm chair expert?  ::)

It's interesting that you keep going to IR as being the gods of testing and yet always fail to quote this part of the final remark: "Like all recent Canon SLRs, the higher quality scores are somewhat below average for a modern sensor. For example, the Nikon D7100 managed 10.1 f-stops at the highest quality level, almost 2 stops better. "  ;)

It's interesting that you still don't understand the difference between total dynamic range and dynamic range to arbitrarily selected noise thresholds.

Quote
And as for IR being sooo much more reliable and well defined than DxO and how can IR get so many stops more DR and the others are obviously wrong, etc. you always fail to quote : "As always, it's worth noting here is that ACR's default noise reduction settings reduced overall noise somewhat "  I.E. they do a potentially randomly manipulated by ACR test that involves all sorts of NR.

It's also interesting that you choose to lie and misrepresent to try and make your case.

A) NR does not affect total DR, though it does impact latitude. Likewise it would impact DR measurements which used an arbitrarily high noise threshold or "quality."

B) ACR's default NR settings are mild and fixed. They are not random nor "all sorts of."

C) ALL tested cameras have default ACR settings.

D) DxO is not testing system DR, but sensel SNR. There is no simple or direct conversion of sensel SNR to system DR. If DxO measured film "sensels" or grain they would report a DR of <1 stop. Yet a piece of Portra film held 12-13 stops and with proper development some B&W films can hit 16-18.

You always use extravagant talk about minor high ISO gains, but then use the most radically minimizing talk about low ISO differences.

No idea what you're even talking about.

I also still shoot film :)

Film...???

Was that something they used before Exmor?  ;D

Neuroanatomist wins the prize for best illustration.   ;D

Almost. I pushed the image 9,001 stops and there was shadow noise in the black lettering. He only gets second place because the image wasn't produced with Exmor  ;D

You don't even seem to understand the fundamental underlying concepts if you really, honestly think that the 70D has more DR than any other Canon camera on the market.

I never said that. I said it had more then the 7D.

So you're saying he TWISTED your words?   :o

Nah...he photographed that particular post with a 5D3, underexposed it for a DR test, and when he pushed the shadows the noise obscured part of what I wrote  ;D

DARN YOU CANON! DARN YOU AND YOUR SHADOW NOISE!!!

Isn't photokina still around 2 weeks away?

NDAs supposedly expire on Sept 5. Can't wait to find out what the actual specs are, though I doubt we will have any idea regarding sensor performance for a couple weeks after the announcement (at least). We need the standard suit of test scenes from various reviewers for that.

I would like to see an Exmor like sensor just to put an end to those threads  :P

But I'm very curious to see what the price is going to be. If it's in the stratosphere I'm not going to be interested in replacing my current 7D for sports. If it's priced similar to the original upon its release, then 65 point AF / 10 fps...if those are the specs...could certainly tempt me.

I think all jrista wants is the DR of the Sony sensors in Canon bodies, because the Sony bodies have a wealth of disadvantages that far outweigh the sensor (IMO at least).  You can't take a picture with just a sensor, and Sony is inferior with nearly all of those other aspects of the camera/lens.  If Canon incorporates an improved sensor in a future EOS camera, it would be the best of both worlds.

For tripod landscapes I can't see any disadvantage to an A7 or A7R. AF speed doesn't matter. EVF lets you judge exposure/histogram before shooting. Tilt screen is useful if your tripod is down low. What's the problem? Durability? The Sony's are weather sealed, though I would trust a 7D or 5D3 to take more abuse and keep going. Battery life sucks but those are fairly easy to carry.

I don't see a "wealth of disadvantages" either. A7 is smaller/lighter for street. EVF with peaking is great for MF lenses. It's not a sports/action camera. No question you would grab a DSLR for that. Despite mirrorless vendors claiming every other week that they have the "fastest AF ever" they are not up to DSLR standards. Not the 7D, 5D3, or any where near the 1DX / D4.

I could pick up and shoot either comfortably for most situations. Obviously Canon wins on AF. But if DR was driving me as nuts on landscapes as it seems to be driving jrista, I would order an A7R in a heart beat.

I don't think anyone else here agrees with you on that point, and certainly no one anywhere else on the net, reviewers or forum goers, would agree with you either.

I think you've twisted Photographic DR into something that handily "proves" (in your own mind) that Canon is right up there with their competitors, when that is the farthest thing from the truth.

I think I've said...repeatedly...that Exmor sensors have a bit more DR and noticeably more shadow latitude and that this sometimes matters. Just not all the time, and not to the degree you believe.

I think I've also...repeatedly...documented that I'm using the standard definition that's in every work on the subject dating back to Adam's formulation of the zone system.

I'm just...ticked off and frustrated.

But not enough to buy something to solve it  ::)

Canon's core technology hasn't changed in years.

Then write letters to Canon USA and Canon Japan. Print and mail them. I'm of the opinion...perhaps false...that printed letters in these situations get more attention then emails and web forms.

I'll never buy a Sony camera so long as they use a lossy compressed file format. Maybe that's just more of the high standards crap...I dunno. But, there it is.

You'll never buy a camera that's relatively cheap ($1,300 for the A7), can use your lenses, and solves the problem which you have spent countless hours making...hundreds?...thousands?...of posts about because of a file format that maybe, on rare occasion, might result in an artifact, even though otherwise the camera completely eliminates the noise and artifacts you're so upset about???

I'm done...I'm out...no more SoNikonSuperMegaDR threads. I can't help these people. They need therapists, not sensors.

This has absolutely nothing to do with technique. My technique is not the problem. Neither is it an exposure problem.

No, it's a problem of what you have built up in your mind. You imagine that with Exmor you could just ditch bracketing, HDR, GND. You can't. The cases were Exmor lets you get away with a single exposure are relatively rare. They come up. They are not the majority.

If your blend/HDR/GND shot is correct then you should NOT have to push shadows or deal with shadow noise. In my blends my shadows are typically brighter then I want them to be, and one of my final steps is pulling them back down. I have never struggled with shadow noise in a blend where I had a properly exposed frame for the shadows.

This is where your Photographic DR is unhelpful. Your Photographic DR tells you nothing about the literal, physical capabilities of the hardware.

Except, of course, for the system's DR  ::)

Quote
However, given Canon's trend...I fully expect RN at low ISO to INCREASE. The 7D had 8.6e-. The 70D has 13.5e- (and with smaller pixels to boot!)

Yet the 70D has...observably...2 more stops of total DR. Once again trying to convert sensel SNR ('engineering DR') to actual system photographic DR fails  ::)

Quote
IMO, HDR, sky replacement, tonemapping, manual blending, etc. shouldn't be necessary unless you have a truly extreme situation.

Landscapes involving bright skies and shadowed foregrounds have more then 13 stops of luminance range and require management (HDR; blending; GND) with ANY modern camera. Interior shots with windows also often require this.

Outside of this most scenes have less luminance range.

Quote
It's entirely possible I like to shoot scenes with more dynamic range. It's also entirely possible my standards are higher than yours (that's not an insult, people have different standards).

It's entirely possible your beliefs about the difference Exmor would make are based on little more then imagination, and it's time for you to buy/rent a Nikon or Sony and find out  ;)

What I really want is Nikon-level sensor quality in a Canon DSLR body.

You have the budget for a $12k lens but you haven't ordered one of the Sony A7's yet?  :o

If you can afford a lens that's the price of a small car...if HDR landscapes are that important to you...if you really believe Exmor will revolutionize how you shoot HDR landscapes...then order the A7 or A7R and an EF adapter.

You don't even have to switch. You don't have to give up your Canon lenses, or your DSLRs in situations where you need fast AF and shooting. (And please don't tell me you always need to push shadows 5 stops so the Sony doesn't solve anything. Most scenes don't have that great of a luminance range.)

Shooting sports, action, any scene that doesn't require shadows pushed 9,001 stops? Grab the 5D3.

Shooting landscapes or interiors from a tripod? Grab the Sony. That should hold you over until Canon changes their ADC architecture.

Problem solved.

As a Canon users, I feel no need to go on Nikon forums and bash Nikon. If I ever switch to Nikon, I'll feel no need to go on Canon forums and bash Canon. Seriously, what's the point?

To some users on here, DR is the most important aspect of their photographic needs. If that's the case, just switch to Nikon and call it a day. IMHO, choosing to live in a perpetual state of DR discontent with excuses like "it's too much of a hassle to switch systems" or "I'd lose too much money by switching systems" ultimately means that DR is not that important to you.

My advise: Switch systems, be happy, and STFU ;D

Yes. Especially when there are three Sony FF bodies that you can adapt Canon lenses to and still have aperture control, AF, and IS! You don't even have to switch, just add. AF is dog slow, but who cares for a high DR landscape?

If you're posting in thread after thread on a Canon forum complaining about DR but you haven't switched or added a Sony A7 body, then DR isn't actually the issue.

I thought it is not the camera, it is the photographer. Are they wrong?

It's not even the camera. It's the super high DR zero shadow noise can photograph a black cave interior with the sun in full view and get detail in both amazing Exmor sensor.

People tried photography before Exmor, but it didn't really work out  ;D

254
Glass has gotten better, film no longer exits.

Speak for yourself, I ran a roll of Kodak through my Pentax MX last week :) It is excellent DSLR detox

Yes...but...what was the shadow noise of the film like, and could it compare to Exmor?  ;D

Because EVF still sucks for action and sports.

Have you tried an X-T1, A77II or a6000?  Modern EVF's are completely capable of keeping up with action, no problem.

I don't think any of them are as good for action. And believe me, I want to see EVFs take over because they are far better for judging exposure and white balance and they're better for MF lenses (unless you have a custom focusing screen). But I just don't think they're there yet, and I imagine at least the next generation of sports cams (7D2; 1DX mkII) will need OVFs.
