Pentax's lens roadmap is quirky. There really is no fast DA normal prime. You can make do, but your compromising something. The 31mm is an FA lens and doesn't have full time af override. Beautiful lens though. The 35mm Macro LTD is a 2.8.


So a 33mm F1.4 DA* would satisfy the need for a fast normal and still be quirky...
The lineup is already crowded in the 31-40mm range (4 primes). What Pentax really needs is a 24-28mm f2 lens. Make it a DA* lens and it forms a nice trio with the DA*55 and DFA100WR. It would be differentiated from the 21 pancake and actually fill a black hole in the lineup.

I say, enough with the cute pancakes…

What Pentax really needs, in my view, is to produce a set of regular (non-limited), fast (DA limited pancakes are slow), * quality (whatever that means), metal bayonet and WR, wide and normal primes that covers the same Field Of View of those for the 24x36 format:

• 16mm f2,8 - similar FOV to Pentax-A 24mm

• 19mm f2,0 (or f2,8) - similar FOV to Pentax-A 28mm

• 24mm f2,0 - similar FOV to Pentax-A 35mm

• 35mm f1,4 and f1,7 (or f1,8) - similar FOV to Pentax-A 50mm

I would also pre-order a regular, non-limited, * quality (whatever that means), metal bayonet and WR, small and light zoom like a 60-120mm f3,5 (90-180mm FOV in FF) or a 50-135 f4,0 (75-200mm FOV in FF).

Cheers,
R

Unfortunately, it means SDM!

Are you concerned about failures or performance? My understanding of SDM failures is that the primes rarely had issues compared to the zooms.

I thought SDM wasn't an issue in newer designs.

Love a DA* version of this…

I agree...there's nothing wrong with them, but it's time to fill out the line up with some real high speed stuff.

I don't have the 21, but I have the 40 and the 70. I like them too. I'd prefer a 24mm f/2 or f/2.8... and if there was a FF to come with it I'd purchase it immediately.

Samyang covers these,
except for the 20/2.8 that the DA Ltd zoom can now handle.

Sure, the Samyang lenses are MF,
but AF is questionable for fast lenses wide open anyway.

I have the impression that the Samyang lenses are full-frame designs…they're definitelly huge, as big as the AF 20mm, 24mm and 28mm f1,8's from Sigma.
Are they any good?

The 16mm is "only" APS-C, but it is f/2.

Yes, it would be great to have dozens of new lenses but Pentax isn't going to have a CaNikon lineup with that kind of lens spacing. There is already a fast 14 and a slow 15 so a 16 would never happen. The fast 35 is too close to the FA31 and there are 3 other lenses between 35 and 40mm's. The 24 f2 sort of completes the large(ish) aperture lineup of DA14, DA*24, DA*55, DFA100WR, DA*200, DA*300 and DA560. These aren't all * lenses but there are similarities (large apertures mainly). This would give Pentax 4 different prime lineups (loose groupings). *, FA limited, DA limited and budget (only 2 lenses).

* quality in the Pentax lineup is a loose definition but typically it means large aperture, SDM, weather sealing and expensive. It's kind of a complementary lens lineup to the DA limiteds and the zooms that you describe would fit into the limited lineup better since they are small, light and not large aperture.

The FA*24 would of course be a good starting point for a DA*24. They did an amazing job re-doing the FA 100 macro while retaining FF coverage.
