Sigma also produced a 18mm f/3.5 some years ago, less popular than the Tokina and Tamron 17mm lenses. I've no idea of the IQ but if it's anywhere near as good as the 24mm/2.8 Superwide or 16mm/2.8 Fisheye it would be well worth a look.

John
I'll chase those lenses up.

Not easy to find as you say.
Zeiss Distagon T* 3,5/18 ZK ££££££££

or some old 3rd party 17mm Tokina, Tamron etc

John
Isn't the Zeiss the twin of the K/A 15/3.5?[/quote]Not as far as I am aware.

John[/quote]No, it's not. I was confused.

But do you want this all the time??

I can see uses for that, i.e archiving pics, but I've seen some landscape pics which look great taken at wider apertures where the narrower DOF has shown some depth.

I'm not really a landscape snapper, but most pics I've seen, which are sharp edge to edge and front to back always seem 2 dimensional and lack depth.
I just think for the money better sharpness should be part of the deal. The lens will inevitably be used for more than Street where edge to edge sharpness could be desirable.

Therefore I think the lens would complement your FA31mm very well. I can see the point of this focal length for street photography - if you are right on top of the subject you can frame them into the shot without them realising it. And while the 31mm is a more obvious focal length, you can have the 15mm in your pocket for wide angle shots of opportunity.
This is why I like my 14mm and 10-17mm for street stuff. You don't have to point the lens at people to grab them.

Street photography isn't about edge to edge sharpness, it's about vibe.

I often shoot at slower shutter speeds to capture the motion in the street, and I mostly shoot at wide apertures to capture depth in the image.
"You don't have to point the lens at people to grab them."

Exactly. Hence my desire for something like the DA 15/4.

looks like you exactly know what you need/want. many of us wouldn't mind fast, small, (limited?) glass around 18-20mm. recent pool on pentaxforums confirmed that. my next is probably da21...
good luck
Thanks Jane. Yeah, I know, the requirements (compact & fast), are mutually exclusive.

"I have NEVER come across a lens that won't produce good quality images without being stopped down to f8 to f11. Where are you reading these reviews?"

I guess as you have the 31 you're perhaps inclining to something wider. But the difference between 21 & 31 is still great.

You obviously know your needs, wadna, but 15 is a far from obvious FL for street photography. The 21 on aps-c is, on the other hand, a classic street FL.
Yes, thanks, but it's nearer to 35mm equivalent than 28mm equivalent. And, yeah, I know, Cartier Bresson used a 35mm lens on his Leica. At least I think he did.
However I would love to try the 21mm.
