Good to see that Pentax took the time to ship after introduction to another level... ("spring 2018", "summer 2018")
Pentax are always late and lagging, I am wondering how are they capable of surviving
The reality set in for me when I weighed up that my coffin would arrive sooner than a K mount 150-600mm/500mm F4,
Three years later still no K mount long tele-zoom...
....... luckily still no coffin! :ph34r:
The 150-450mm is a good lens......but for me and many birders 450mm just isn't long enough even on APSc!
The DA 560mm was IMHO a strange offering, very long, telescope optics, only F5.6 and needs stopping down to be sharp, Pentaxians had been waiting for an affordable long tele-zoom and they got offered that lens with a 7,000 euros price tag.......that lens should have been affordable..........proof, barely a soul bought it!
Pentax are in a super position with their association with Tamron, IMHO they should bring out the 150-600mm G2 in the K mount.....as well as many others.
........Yes you may say.......it would spoil the sales of their own 150-450mm.....but, so what?..... it would prevent much brand migration.
A lot of Pentax birders have gone to dual systems now, with Nikon for birding for the availability of long glass, in the end I had to succumb to the endless new improved affordable glass coming out, 98% of which is unavailable in the K mount.
At this moment, I'd say e.g. a Nikon D500+200-500 or a third-party 150-600mm would be a better option for birders such as yourself.
As for Pentax, I believe their strategy should allow them to expand their product line with OEM products, rather than rebadges (as a birder, why would you get a Pentax with a weaker AF, and the same lens you can buy cheaper for Canon/Nikon?).
Even "killing" the 150-450 might be a mistake, while you'd love the added reach of a x-600mm lens, others might prefer the more manageable and shorter lens.
Last but not least, the DA 560mm f/5.6 is much more affordable than a 600mm f/4 from the other manufacturers.
Are you sure it's performance is worse than a Tamron or Sigma 150-600? You don't even say which Tamron or Sigma, and some of them are quite weak at 600mm.
