The SMC Pentax 28/2 is a very different lens from the Pentax-m and Pentax-a 28/2 which are much lighter and more compact. The SMC Pentax is actually a Distagon. _________________ pentaxian |

From these 28mm 1:2 lenses i only know the Hexanon. I would not recommend it for landscape, since its corners aren't that sharp even at f5.6.
The best 28mm lens i've ever used was the Zeiss Apo Distagon 1.4/28mm. Slightly lower contrast at f1.4, but enough resolution wide open even for the 42MP A7RII corners! At about 1.5 kg this lens was way too heavy for my kind of work ... it is nearly as heavy as my FD 2.8/300mm Fluorite (1.9kg) ... _________________ www.artaphot.ch |

If you don't need a bright aperture, f/2,8 or even f/3,5 lens may be sharper wide open.
My 28mm f/2,8 Rokkor version III is very good, but my OM 28mm f/3,5 is better. |

I don't own a Hexanon 28mm f2 but I do have the Hexanon 28mm f3.5 (7element) and it is a very good lens and I like it a lot. Having said that I mostly use it on my APS-C Sony A6000. What it's corners on full frame are like I don't know.
Anyway, I don't understand the obsession with how sharp a wide angle lens (or any other lens for that matter) for landscape use is at full aperture. Maybe someone shoots landscapes wide open but I, and the majority of landscape shooters I suspect, use apertures in the range of f8 to f16. To me, it's the quality of results at these apertures that interest me. _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |

Edgar,
Might I suggest the Distagon 28/2.8 (MMJ) in C/Y - great lens on the A7r and on film (where it started out).
I think I saw someone else mention the CV 28/1.9, which I liked but had some corner issues on the A7r.
One other option if you don't mind going up from 28mm to 31mm is the Pentax smc-FA 31/1.9 Ltd: I love it and good on the A7r across the frame. And very good going from mid-far distance.
For those lenses, I can't really talk to performance wide open as that's not how I used them. _________________ Lochlann

That was me. The corner issues are gone on the A7R II, but Edgar looks for APS-C usage anyway. _________________ Thomas Bernardy

Lochlann. the Distagon 28mm, I think, would be perfect. I'll have to sell a few lenses to afford one though! _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |

Not too bad at all. Not sharp into the corners but then I didn't expect it to be. Allowing for a little cropping at the composition stage and the lens performs very well, especially when you consider how much they sell for. _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |
