I've been using DxO products (Optics Pro and now PhotoLab) for some years now. One of the things I like is the availability of modules for most of my camera/lens combination.
The list of modules for each supported camera can be found here:
Supported cameras | DxO.com
There's often a lag in DxO bringing out modules for new lenses and cameras - sometimes up to 12 months. But it surprises and irks me that DxO haven't released any modules at all for the
Pentax HD DA 55-300 f4.5-6.3 ED PLM WR RE, which has been on the market since June 2016 and must surely be one of Pentax/Ricoh's most popular lenses. It's not just cameras that required a firmware update to use the PLM lens (like my K-3) that are unsupported; even new models like the K-P that have native support for the PLM don't have a module for it.
For some lenses the availability of a module is more critical than others. There isn't one for my FA*300 f4.5, for example, and I'm sure there never will be. But that lens doesn't need much correction anyway. The 55-300 PLM, on the other hand does - for example, it vignettes like crazy.
As far as I can see, all of the other DA and DFA lenses are now supported. In the FA series there's only the three Limiteds (31, 43 and 77) and the FA 50 f1.4. (Some FA lenses might get coverage accidentally: for example, I have the FA 50mm f2.8 macro, which isn't listed - but DxO treats it as the optically-identical DFA 50 macro, which is.) There are no older Pentax lenses supported. Most of the popular relatively recent lenses from Samyang, Irix, Tamron and Sigma seem to be there.
Are there any other conspicuous absentees?
I've filled in the suggestion box several times, but I'm thinking that a concerted campaign for a handful of lenses (and cameras?) might just have some effect.
