I reckon that you get a lot of requests for specific camera-lens combos, so much so that it must seem like fighting a deluge. And, on the whole, Pentaxians have been able to rely on DxO to provide optics modules for new and current Pentax lenses in a timely fashion. I also understand that Pentax has arguably become a niche brand that will likely not be your top priority when allocating your resources.
But, then again, given the consistent history of your brand support (and the somewhat patchy experience elsewhere), and the excellent processing results of Pentax PEFs and DNGs with PhotoLab, you may have a small but loyal customer base in the Pentaxians using your products.
Could it be, then, that the HD PENTAX-DA 55-300mm F4.5-6.3 ED PLM WR RE has somehow slipped under your radar? Because otherwise it would be hard to believe that such an absolute bread-and-butter lens, released in 2016, and likely one of the bestselling current Pentax offerings, is still without support. Over on PentaxForums, there is a long and increasingly disbelieving thread of users who are, shall we say, puzzled by how their formal suggestions via your site regarding the optics module seem to have yielded nothing but the usual apologetic responses for years.
Is that really going to be DxO’s last word on the HD DA 55-300mm F4.5-6.3 ED PLM WR RE?
