First of all, for the D FA*50 and D FA*85, they don't have equivalent, they have inferior.
Quote: FA series with a variable aperture that would be useful for any new user to start / start eg: 24-90 / 28-80 / 80-200 / 80-320 or a new one that Pentax has never had in its FA range 28-125 / 24-105,
They have the DA 28-105. They still have all the old FA. I still have my FA 35-90, although I don't use it much because the DA 28-105 is so much better, And carrying a little Sigma 24mm AF macro is convenient if you think you need 24mm. As for the 80-320... the DA 55-300 PLM is best in class.
The pattern continues, ignore what Pentax has done really well, sell half truths and fictions to support the notion that to shoot Pentax you have to punish yourself. Those of us who have proved that to be untrue will always object.
My carrying kit is the K-3, 55-300, DA 16-85 or DA 18-135, and DA*55 1.4. I lack exactly nothing I'd actually pay for. For the K-1 Sigma 24 macro, D FA 28-105, Rokinon 14 28, DA*200, DA*60-250. Tamron 300 2.8 (or DA*300ƒ/4) with the 1.7x AF adapter of HD DA 1.4. Anything I don't have is too heavy for me to carry. Not to mention that the DA 55-300 works acceptably well with a few caveats on the K-1 for a light weight fast focussing kit that can't be matched on any brand.
People seriously need to value what they have, instead of focusing on what they think they could take advantage of. I own 22 Pentax compatible lenses most of which I rarely use. Any lens I'd buy now would spend most of it's life in my lens cabinet.
Pentax has done a really good job of making excellent consumer grade glass and covers that with the most important FF pro glass, even if they don't cover every niche. Currently, anything they release is top shelf. If they aren't currently releasing it, there's something there you can use. Can't afford the D FA*50 1.4? D FA 50 macro, FA 50 1.4, DA*55 1.4, DA 50 1.8. Some folks seriously need to study the catalogue.
In medium telephoto. D FA* 70-200, or DA*60-250, or DA* 200, or DA 55-300, or FA 80-320 or FA*80-200, or D FA 70-210, or F 70-210 or D FA 100 macro with TCs. Seriously? What gives?
10 of those lenses are still in production.
I point these things out for the record. I wouldn't expect anyone who would make such a statement to change their mind.
