Well not a new rumour, IIRC, there was a rumour similar to this earlier.

Pentax 12-24mm f/3.5-4.5 lens patent | Photo Rumors


One can only hope its a WR lens. Don't think I'll need a f2.8 for a wide angle, just a solid performer, tough and quiet lens with dc motors. I would like it to have sdm but that will probably make the price go sky high.

Can someone please explain why they'd want to remake a lens they already have, instead of expanding their lens range, like a 10-20/10-24/8-20mm???

I think we all know how good the 12-24mm f4 was, albeit its biggest bug-bear was its CA control and distortion. Well looking at the patent drawing, 15 elements in 12 groups with 3 asp and 3 ed elements compared to the older lens with 13 elements, 11 groups with 2 asp and 1 ed elements , and longer and bigger than the current 12-24mm f4. The new lens might be design to correct the current flaws. Furthermore the older 12-24 f4 was co-designed with Tokina, maybe they just want to step away from any affiliate of Hoya as well?

In regards to the lens design of the da 12-24 f4, I saw some conflicting info, Photozone states it as 15 elements and 12 group whereas bdimitrov has it as 13 elements,11 groups. In this case I followed bdimitrov.




Me? Like I said I want a WR feature, where I go hiking, I tend to get drenched.

If optical quality was as good as the current 12-24 then i'd trade mine in and buy a new one just cos of WR alone.

I think Pentax is gonna build this one considering i haven't seen many 12-24 available new online these days from B&H or Adorama. No new stock must be coming out...

If they make it WR I may just give up 10mm on my sigma to get it. Haha

Hi rumour, any idea when it would be released ?
Should I hold back purchasing Pentax DA 12-24mm lens first ?

Love my 12-24. But I do wish it was 10-24 F4. I think it will be great. WR is a good to have but not necessary.

Also hope the quality control tighten up as well.
