I was amused enough to actually read dxomark Pentax 645Z sensor review as well as Hasselblad X1D-50c sensor review. I didn't know about this until now, unfortunately I know now, it's all your fault

Anyhow, 645Z review is much more nitpickier, the difference in the way words are chosen is striking. I don't bother to list everything but here's one example.

Look at color depth comments in 645Z sensor review, where Hassy (26.2 bits), 645Z (26.0 bits) and D850 (26.4 bits) are compared:
QuoteQuote:
This graph illustrates where the Nikon D850 wins for Color Sensitivity that is, at the lowest ISO setting. Once you push the sensitivity (ISO) above that value, it actually drops very slightly behind the two medium-format cameras. Nevertheless, if you want the highest possible Color Sensitivity, the D850 is the one to go for among these three cameras. Of the two medium-format cameras, the Hasselblad X1D-50c is very slightly better at the lowest setting.
OK. But in Hasselblad X1D-50c sensor review, where Sony AR7 II (26.0 bits), the camera with exactly the same color depth score with 645Z, fights instead of 645Z, they say this:
QuoteQuote:
With such slight differences among them as to be indiscernible in the real world, the Hasselblad X1D-50c, the Nikon D850, and the Sony AR7 II sensors all boast excellent color of around 26 bits at base ISO, and very good color of over 20 bits up to ISO 1600 for normalized print results.
Exact same set of scores, but in one report, D850 is the one to go and X1D-50c is slightly above 645Z, that's important enough for them that they needed to highlight the difference using one whole paragraph, in another report the same difference is indiscernible in the real world and they needed to highlight that these are all basically the same.

Sad, I was thinking about switching to dxo from adobe lightroom.

Well, they might make for lousy and compromised journalists, but apparently they write decent software ...

Exactly, i don't see the relation, unless revenge embargo.
This said, DxO's Photolab still lacks a few features to be a complete competitor for LR.

Regardless of how one thinks they have "dissed' the 645Z (which they have), Its very good software. I'm not into the Adobe Model of Digital Asset Management. I just use a simple folder tree sorted by date and use Zoner ZPS X to do my key wording in but I'm almost hopelessly behind on the key wording thing. What I really like about DXO PhotoLab is the "Prime" noise reduction mode which unfortunately works only upon RAW export or printing. That being said, I think its the best noise reduction available with the possible exception of Capture One Pro 10 which is over twice as expensive and has a Digital Asset Management that I don't need or want.

Another unique feature of PhotoLab is the extensive DXO database of camera and lens combinations called Optics Modules that the program uses and applies corrections as soon as you open a folder that contains RAW images, if you haven't already downloaded the proper Optics Module the software will prompt you to download the needed modules.

There are enough sliders to satisfy most slider freaks.

All in all I think its been a good choice for me and I'm just scratching the surface of its usability.
