DR is the same. So is resolution.
Let's think in terms of thresholds rather than absolutes. If you have 16 stops of DR, and only 4mp of resolution-- another stop of DR is probably going to feel worthless compared to 10 or 20 extra MP or resolution. If you have 100MP of resolution, but 8 stops of DR-- 10 to 20MP more resolution is going to feel worthless compared to 4-8 stops extra DR.
I voted #2, btw. DR is important to me. Resolution is important to me. Color accuracy and noise characteristics are important to me. When one of those areas is lagging compared to the others-- that's the thing that I set my sights on rectifying.
When I went from my 5D2 to A7rII (a transition many have made, or are considering: 5D1,2,3, 6D -> )... I was able to get significant jumps in all those areas (DR, resolution, color accuracy, noise characteristics). The 5D4 offers something similar, but with a bit lower resolution jump. The 6D2 does not offer much (noise).
As I see it, the reasons DR comes up so much:
i) It's probably the only area where Canon has lagged dramatically, and now, only recently, has caught up.... in some of the line (the 6D2 is a disappointment there).
ii) Every time it comes up as ONE of the important factors (not the holy grail), a small group of people go on a crusade against DR mattering at all or much at all as if their needs are the only needs and those of us who value DR are fools. Side note: That small group often accuses the folks who seek DR as one of a number of qualities as: lazy, low-skilled, spec-chasers rather than thoughtful, balanced, skilled photographers.
We've seen this over and over and over again with different measures with different manufacturers. FF doesn't matter-- until it does. Resolution doesn't matter-- until it does. CFA or color accuracy or metamerism doesn't matter-- until it does. DR doensn't matter-- until it does. "Until it does" seems to mean, "Until my manufacturer of choice embraces it as an important area to improve-- and takes steps to improve/offer it."
Trying to corral all talk of DR to one thread is like trying to corral all talk of resolution to one thread. It's silly and futile. Cameras and systems are a complex mix of specificiations, real-world use, and compromises. Picking one metric to ignore... is just as silly as picking one metric to rule them all. DR is neither. It's just one more IQ component-- an important one, no matter where you set your threshold... you set it somewhere-- neither without importance or the holy grail when speaking broadly across a mix of photographers and needs. Same with resolution and ......Show more →
All of what you say is true. So why do these conversations get so heated? The reason is because this is a gear forum and 1/000th's matter to some, plus a good slice of brand and model loyalty.
I've just got used to it.
