UWA predictions

**todd** · 03-02-2015, 11:35 AM

Apologies if there is discussion elsewhere but what are your predictions/fantasies for the next Pentax FF UWA release that will control our minds? Could they actually pull off something in the 15mm range? How many thousands of dollars would it cost?

I just closed a deal over the phone for an A 15mm f3.5. SEK 3500, ~ USD 420. A fair price if you ask me.

Update and re-release the FA 20 as D-FA, HD WR. 20 is plenty wide for me.

Considering the apparent hogginess of Pentaxians with the existing stock of FA20, I'm with you!

Sigma's 15 fisheye may not do mind control but it is a very nice lens!

**Ash** · 03-05-2015, 05:16 PM

The FA 20 will be interesting to see perform on a FF dSLR.
On APS-C, I'm so far ambivalent, as the DA 12-24 and DA 21 both produce better images at all comparative apertures.
Sigma's 15 will be plenty wide on a FF, just like the DA 10-17, but that A 15/3.5 will be something special, bilybianca...

**Ash** · 03-05-2015, 05:27 PM

There is a DFA and a DA UWA zoom on the roadmap. The DFA version sounds like a 20-35 of sorts. They do, of course, have the FA 20-35 to base a FF upgrade from, but if the DFA version is WR it would have to have quite a different construction.

"Careful" examination of the red bar on the roadmap suggests 15-30mm. (Not the best way of identifying precise details!) Speculation is f/2.8.

D FA(*) 15-30mm f/2.8 AW would be good competition.

I own a sigma 15-30mm f/3.5-4.5 EX IF which is a very useful focal length range on both APS-C and on full format.

**Ash** · 03-06-2015, 05:02 AM

I've tried Sigma's offering and found it to be an interesting option for FF but wasn't overly impressed by its IQ in comparison to the DA12-24 on APS-C. 15mm rectilinear FOV is incredibly wide on FF that it has such limited shooting application, but the fact that it's a zoom helps the lens's utility.

VoiceOfReason · 03-06-2015, 08:08 AM

12-28 WR or AW of some sort.

But would that be called (on the roadmap) a D FA Large diameter wide zoom?

The lens that was called (on the September 2014 roadmap) a Large diameter telephoto zoom is now known to be the HD D FA* 70-200mm f/2.8 AW.

I think there are some code words here. "Large diameter" may mean "large aperture", perhaps even "constant large aperture". (But perhaps I'm reading too much into this).

DeadJohn · 03-06-2015, 10:52 AM

The estimated 15-30 zoom on the roadmap is logical. That fills the gap below the FA 31 in the current lens lineup for FF. Ultrawide primes (a refreshed FA20, maybe a new 15) can come later. The name on the roadmap suggests f2.8 for the zoom but nothing's officially set.

I would be okay (yes, it's not all about me, this is just my opinion) with a constant f4 or maybe f2.8-f4 variable if it keeps the lens size and cost down. I don't care about thin DOF when shooting ultrawide, and wideangle+SR is forgiving enough to be used handheld in low light at f4. If Ricoh decides it has to be f2.8 to meet customer expectations/needs, so be it.

no an f/3.5-4.5 wouldn't be called a large diameter zoom - Considering that aperture range the sigma 15-30mm is still, a substantial lens.

Pentax K 24mm f/2.8, SMCP-FA31mm f/1.8 Limited, Sigma 15-30mm f/3.5-4.5, Sigma 18-35mm f/1.8.

Physically the sigma 15-30mm it is wider than the Sigma 18-35mm f/1.8 ART*, making an f/2.8-4 version of the 15-30mm would be an interesting prospect, the front element alone would have to be much larger than this:

* Considering it can cover full frame, it is a remarkably light lens.

I agree with all of that. And a smaller aperture lens may be more likely to accept screw-on filters of a reasonable size.

At least I have at least 7 months to think about this! Given that I have the DA 12-24mm f/4, I have no use for a high-spec FF wide angle lens until I have an FF camera.
