Originally posted by biz-engineer You forgot the D-FA*50 and the DA*11-18. So in total that's 3 new premium lenses in 4 years, plus the coating on other lenses and the Tamron rebrand, that a lot of new lenses for a small brand like Pentax (3% market share, or less).
If you go for 4 years, the "easy updates" list should be shortened accordingly.
In terms of lenses, between 2017 and 2020 we had:
- one Tamron rebadge, the 70-210
- two HD versions of existing lenses, the 10-17 fisheye and the 35 f/2
- three new Pentax designs, all high end
On the camera side, the KP should be included (besides the K-1 II).
No HD DA Limiteds, no kit lenses, no multiple Tamron rebadges - as those happened earlier.
Expand the interval, and you'd have to add more new lenses and more cameras - including the K-1.
