I thought AW was used on '*' lenses? Or am I confused?

Star★ lenses are always sealed, so in the past they didn't need an additional name.

It's AW; written on the lens.

Somebody should tell DPR to put their glasses on then.

They're writing "AW" everywhere except for one place. It's not that bad.
I also sent them some corrections about the lens' specs - namely the mount (KAF4) and motor type (ring-type ultrasonic).

On the other forum, Asahiman posted an image with the optical diagram:

15 elements, with no less of 8 elements in the focus group.

Ooh. We like

Man, look at that thing

Of particular note:

"Everything of this lens is developed and patented by Pentax and Pentax produced.

The tokina version is made by Pentax and tokina is using the Pentax patent."

That may quieten a few of the naysayers

A neat way to make the lens affordable by volume

He's made a small correction

"Sorry, little mistake....the tokina is made by tokina but uses the Pentax patent.

Different coatings."

As expected, I think

Ah, right... not unexpected that they'd manufacture theirs... Nice to know it's a Pentax design, though

Kunzite · 03-04-2018, 03:42 PM

We already knew that.

All 3 new 1.4 primes are developed and patented by Pentax, the new APS-C zoom is patented and developed by tokina.
Best regards
