The other DA limiteds also face these design objectives and constraints and are within the $400-600 mark
Compared to the other lenses in the limited series range, this lens seems a bit overpriced. It would be hard to convince the buyer at $1000.
I also think that this zoom may have relatively prominent CA as Pentax design philosophy has historically been to not fully correct CA due to the ability to fix it in post-processing. This is not necessarily a bad thing if the CA level is not excessive like in the 16-50mm.
Originally posted by lytrytyr Basic kit lenses have poor edges at their short end,
and the better Pentax zooms have excessive CAs there.
The design challenge is to avoid these issues,
in a small package.
