If this 52MP camera really is going to be the 5D Mark IV, then it really, really needs better ways to reduce file size in-camera, including cropping (i.e. 1.4x, 1.6x, 2.0x) and way better reduction methods than mraw and sraw, such as the ones used in the new DNG spec. I'm not really interested in 100,000 100MB raw files. That's 10TB!
I concur that better lossless compression would be welcome, but why does it matter what they call it? Seems weird.
Has nothing to do with what they call it.
Just making sure. The "if this is going to be the 5D Mark IV" leadin made it sound like you might live with large files in a for example 1DxS, but not a 5D4.
I like having all my files with me, and I don't like "smart previews" as they are not full resolution and so can't be used to determine focus or motion blur.
I agree, they're not as good as having native data local, but they're great for archived stuff. At the very least, they allow me to see on my laptop (which only has 256GB capacity) my full library as-processed on my desktop (which currently has 12TB capacity using "only" 4TB drives in addition to two SSDs for software and workflow), and know what images look like without the annoying 'not found' error I'd get if I merely broke the link between the catalog and the data (i.e. viewed a standard preview without the native data local).
But hey, to each his own.
