Third Party Manufacturers / Re: Dynamic Range - Try it for yourself, conclude for yourself: 5D III vs. A7r« on: October 03, 2014, 11:00:42 PM »
What gets boring about this discussion is that those who attack the 'high DR advocates' are invariably coming from one of the following flawed perspectives:
1. It does not matter to me, so it should not matter to you. Sorry, around whom does the universe spin?
2. You do not understand how to expose correctly. Condescending and ignorant view point.
3. If Canon pros can make great photos, then you must think you are better than them. This ignores entirely the plethora of factors that lead to some people shooting Canon versus other brands. It also has no bearing whatsoever on the facts being discussed here. What's more it is about as logical as saying 'Mr X, the Formula 1 racer uses a BMW 535D as his daily driver so I cannot see why its not good enough for YOU.... without recognising that you might live on a remote farm in Scotland, accessed via a track passable only to 4x4s!
4. When buying a camera, DR is only one consideration. You should look at the whole camera! Yes, but it may be that amazing AF and live view matters not to a given person, whereas high DR is actually more important for specific applications. Some people don't want to 'work around' the issue when they don't have to, or own multiple systems just to cover those high SBR moments that a Canon will struggle with... and carry both 'just in case'.
5. Show me the paper or monitor that has 14 stops of range - there are none that are close so this 'data' is wasted! Sorry, but this shows a total lack of technical understanding of the issue. You need to learn about the relationships between subject brightness ranges, capture and output. This is basic stuff and its sad to hear how many people get their teeth stuck in while showing their ignorance on this one.
6. A five stop push is unrealistic and therefore shows us nothing about real life application! Sure, 5 stops is extreme, but you try even 2 stops when those shadows are on the floor and the Canon still falls apart, especially if you want to make large prints. And yes, you can encounter these scenarios every single outing if you happen to shoot the sort of subject matter that will require you to expose to include hot highlights and then lift deep shadow. Sony sensors are dramatically better here and its visible in an 8x10, never mind a 30"
7. Shadows are supposed to be shadows you fools! They aren't supposed to be lifted that much. Once again, you don't understand the basics of exposure and tonal placement in relation to the exposure latitude of the materials you are working with. Put in crude and simple terms, the photographer decides what is shadows and if the exposure means they fall darker than desired, its better if the photographer has recourse. There was the same issue in the darkroom, when you did your best with exposure and development, but due to various factors were left with heavy dodging in the darkroom....
8. All cameras are compromises. You are getting all upset because Canon is not perfect, but neither is Nikon. Sure, this is true, but as everyone's needs differ and as the compromises differ from one manufacturer to the other, this is a non-point. We can still prefer one compromise over the other. Besides, now that Nikon has sorted LOTS of issues out with the D810 and D750, if Canon does not nail the DR and banding issue, its going to be difficult to show a strong reason to be selected. Besides, none of this diminishes the frustration that far smaller companies with much lower budgets produce much cheaper cameras with much smaller sensors with much more dynamic range! Canon has ZERO high DR options. None at ANY price.
There are a lot of people commenting here like they are real pros, who are clueless on the issues about which they are commenting. Then there are those who just think that anyone whose needs differ from their own are delusional. Either way, its really boring hearing the same tired old counter-arguments from people you'd think are having their identities attacked.
....So I would be interested to know if there is anyone out there who will disagree with the following statement. If not, there is not a lot more to say:
"Sony sensors do have measurably higher DR than existing Canon sensors. They have measurably and visibly lower read noise and banding too. The lower DR of Canons and the appearance of banding can be a factor in some photos and significantly reduce the quality of the end file. While this may not be important to most people most of the time - and here the Canons are just great - it is hugely important to some people a lot of the time because of how they use their cameras and what they use them for."
So? So you are right. I agree with with your thought process.
