DFA 24 mm f.2.8 ?

Mundus · 03-07-2016, 02:43 AM

Look closely in this pdf . Seems like somebody has *pasted* info about a 24 mm *Ultrawide angle* f.2.8 , in this document about the 28-105

Not f/1.8 ? Pentax is doomed!

Sweet finding.

This is clearly a mistake, a typographical error most likely.. An ultrawide-angle lens is shorter than the shortest edge of the format: in this case on the Pentax K-1 that would be any lens shorter than 24mm.

Great catch!

I doubt it. If it was a typographical error it wouldn't be *f.2.8 *

Its probably a mix up with 24-70/2.8, since pentax doesn't use SDM in any of its new lenses any more. (except for tamron made lenses of course)

**pres589** · 03-07-2016, 04:05 AM

Typo.

Kunzite · 03-07-2016, 04:11 AM

1. It's too early to leak lenses marked as "2017 or later"
2. SDM, that's a giveaway. No Pentax lens used SDM in a while... and there's no current Tamron 24mm I'm aware of.
It appears like an incomplete edit of the 24-70.

Yep. I would expect a DFA24 to get a f/2 aperture btw.

Part of the description of the D FA 24-70. If it were a prime it wouldn't say constant aperture. The 2.8 or maybe 2.0 wide-angle will be 28mm. De ultra wide angle will be a 24mm f1.4

Zygonyx · 03-07-2016, 05:37 AM

If this is 24/2.8, the world will laugh.... not only the PentaxIsDoomers

It seems to me - it's from DA24-70

The "constant F2.8" is proving it's just taken from a zoom description so it's from the 24-70/2.8.

pathdoc · 03-07-2016, 07:13 AM

Agree - I think the 24mm ultra wide angle bit is just referencing the widest zoom (to distinguish it from the common 28-70).
