Then why DA 15mm Limited? Or the DA 35mm Macro Limited, for that matter.
Now this one, I agree with.
For cannibalization I'd add the DA*16-50. There's your weather-sealing, and your profit margin.
Generally, if you're able to spring for primes, you've got a top zoom in your sights as well. Generally the same market—people who take their optics seriously.
The DA line replaces the FA line, and 35mm is to APS-C what 50mm is to the old standard. That one makes sense. Or the 30mm. Not both. Add the hand-crafted legacy legend 31mm and the field is crowded. Too crowded for Pentax's market share. They need a very long zoom, and a longer prime, amongst other priorities. A 30mm (sealed or not) is a lesser priority. They'd also have to compete with Sigma. Very crowded.
They've gone with the DA 35 and dropped the 30mm from the roadmap. It's development is suspended until further notice. The DA 35 represents the sunk cost and the investment case. It also boats legitimate macro capabilities. Pentax is marketing flexibility, not specialities. It lost market share being the uber-prime dealer. Now it has to use more market savvy and a great deal more care.
