D FA 21 Limited is one of the three.

If this lens was faster than f4, I’d expect the Depth of Field scale to reflect that, although the graduation marks are getting rather crowded toward the centre, so perhaps it is an f2.8 lens.

Let's see...
- FA 43mm f/1.9 Limited - DoF scale starts from f/4
- FA 31mm f/1.8 Limited - DoF scale starts from f/4
- FA 77mm f/1.8 Limited - DoF scale starts from f/4
- DA 21mm f/3.2 Limited - DoF scale starts from f/4
- DA 35mm f/2.8 Limited - DoF scale starts from f/11
- DA 70mm f/2.4 Limited - DoF scale starts from f/4
The only Limited where the DoF scale starts with the lens' maximum aperture is the DA 15mm f/4.

It looks quite big in the video. Not to big but a fair bit larger than the fa 31. He waves it around and filmed himself on what appears to be a wide angle common laptop webcam but if you play the video at slow speed (gear icon) you get a better impression of the size.

With some luck they've made it f1.8 but allowed it to have some "character" until 4 or so. I guess this is something the limited line might allow that the dfa* doesn't.

Using very rough techniques, I suggest that the DFA 21 Ltd will have 67mm filter thread and a body width of about 75mm. That makes it pretty close to the FA 20/2.8 in size...

so this is something in the " works "

and may be years in the future

In the video they said they’re trying hard to schedule for 2021. They’re rarely that explicit when discussing release dates.

That's the best news in a really long time. They are finally making up for making the 28-105 being 28 instead of 24 and giving us K-1 shooters a quality lens to shoot with.

wstruth · 05-15-2020, 06:55 AM

Its already haunting my mind and i only say the announcement an hour ago!

kdre · 05-15-2020, 06:57 AM

Yes! I am a huge limited fanboy and will buy it the moment I can preorder it. Thanks, Pentax!

I do wonder if they have moved the green pip to a location that makes it useful for what they were intended for or if they have just done it for cosmetic reasons.

Aluminum construction!

It certainly does, I have to say the built in lens hood is going to be a bit of a nuisance for users of square filter systems like myself. I use screw in filters a lot of the time, but use of square system GND filters can have issues with vignetting.

After all these years it would be more worthwhile to move the lens release button solving that problem once and for all.

Weird that they don't publish the lens speed......

Finally the DA 15 equivalent for FF. Oh yes, it will be mine. Just need to find an early MIJ copy....

My guess is because they haven't decided whether to put a weird aperture number a-al fa43. (f3.9 or f2.7

)

They probably aren't sure about it yet, perhaps the optical design isn't final... or they don't want to drop so much info at the same time, giving us a heart attack

. I'm betting on the second, two models (black/silver) with more or less "final" dimensions point to the lens being quite a way along development.

I wonder why they moved the release button in the first place. I don't think there was a pressing need to do it.
