I'm really pleased about this. As a new Pentax user shooting K1 and 645z with all new generation glass I am not very keen to go back to older generation glass like the 55 or the 43 (despite the many positive things I hear about them). Plus 55 is too long. I am pining after my canon 50 f1.2 since I sold all my Canon gear so this looks like the perfect replacement. I hope it has world class image quality. I might even sell my 24-70 and buy the 70-200. 15-30, 50 and 70-200 seems like a good setup for my shooting.

DFA 20mm (or wider) up next!
*crosses fingers*
That would be seriously righteous. I've had my eye on the Rokinon 20mm for a while now but I'd definitely prefer some WR

I'm now getting nervous about what they'll do with the Three Amigos when they get round to updating them. Compactness seems to have fallen off the back of the Ricoh/Pentax truck.

I'm not sure about competing offerings, but do any of them offer image stabilization in a F1.4 50mm? It's not an intrinsic trait of the lens but, given that the K-1 has very effective stabilization, it will be a powerful selling point nevertheless.

Is there a law that says no FF lenses ever vignette?
From hanging around sites like lenstip or dxomark too often, a full-frame lens that doesn't substantially vignette seems a rarity. Particularly for fast-primes.

2-3 EV light-loss wide-open in the corners - even on lenses costing several thousand dollars - seems normal on full-frame.

For example, on FF at f1.4 the Nikon 50mm f1.4G light fall-off in the frame corners is 56%, and on the Carl Zeiss Otus 55 mm f/1.4 ZE light fall-off is 51% in the frame corners (-2.05 EV). It seems very visible.

I want a 24mm F/1.4 first.
Me too. There are very limited options at that FL. Hopefully 24mm comes next.

Sigma killer, finally!
Yes for sure, they need to not have sigma hanging around, forward with Pentax lenses is the way. I don't mind Tamron but not Sigma.

Nice one Pentax, look forward to it

The Princesses will be foresaken, thrown on a pile of wide-aperture glass and AF motors.

Sigma copy in fact: huge, heavy. not pentax any more
Maybe that's where a none star DFA 50 f1.8 will come in. Somehow that's the trend of modern lenses, in order to get ultra high performance, size and weight will definitely increase.

Awesome. Now where is the matching 35mm F/1.4 and the 85mm F/1.4?
+1, and a 135mm f1.8 please.

They stick to the plan, a normal angle lens first. Hopefully some friends will be around the corner.
f/1.4 calls for the same f-stop for a follow up 35 and 85 lens. Pentax is going the whole nine yards, I guess.

My DA*55 is bloody near perfect on the K-1. Vignetting is not a problem and chromatic aberration is minimal. Maybe I was lucky with my copy, but I won't be rushing out to buy the DFA*50. I'm delighted Pentax have produced it though

Some examples: pixel peeping and EXIF available in Flickr. Any cropping is mentioned.











This one is cropped a little, but to remove distracting elements, not vignetting.



a crop of the above for those who doubt the lens' resolving power

Given the length and girth and depth of the hood, I would have guessed a fast 85.
Yes, it looks like a 85mm. At first sight, this lens even looks like a 645 lens.

The 'Limited' line has always had a different design philosophy. No reason at all not to have a line of DFA* glass that is big, fast and weather sealed along with a line of small, slower Limited lens in metal craftsmanship. Different markets. I think we will see DFA*50, 85 and 135mm this year. And perhaps Limited 20, 31, 43 and 77 next year. Just speculating of course.

People were asking for modern lenses, I guess that means big also
