The best all-rounder is most likely the DA 35mm f2.8.
Second up would be the FA 35mm f2.0. But because it is no longer made and is much sought after, I think you'd have to be careful not to overpay for a second-hand example whether Pentax or Samsung.
I have an SMC A 28mm f2.8 (manual focus). It's OK for black and white but I haven't found it up to the standards of my limited lenses. Time to move on.
I would not buy an FA 31mm. I think it is far too expensive for what it is, and personally I would not feel much at ease strolling around with such expensive kit.

Why on the "other" site does the 30mm F1.4 Sigma get 9.7 rating?
Are people buying 2nd hand copies that are duffers?
If you had a crap copy and wanted rid, you just keep schtum and sell it, leaving the buyer to work it out?
Or are these new copies with some variation?

Depends on your priorities, but anything in the 28-35mm should do. Your in-production options are:
*Sigma 30mm f1.4 - fastest lens here and also the cheapest (relatively speaking). It has no resolution to speak of in the far corners wide open (and isn't great at borders either), but at f1.4 your extreme corners are going to be blurred (ie bokeh) anyway
*FA31 Limited - fabulous, but it's £1000. If you have £1000 to spend on photo gear (and don't, for some reason, want the DA*50-135 ), the FA31 is widely regarded as one of the best prime lenses ever made.
*DA35 Macro Limited - not a fast lens (only f2., but if your primary use for it will be outdoor/street work it is very well regarded indeed. It also has the advantage that, though 35mm isn't a great macro focal length, you never have to worry about the minimum focus distance for normal shots! Only weakness might be the slow autofocus, however unlike the others on this list it has Quick Shift (ie you can turn the MF ring while in AF mode) so you can give it a helping hand if it decides to hunt.
Of the used options, the FA35 is just under a stop faster than the DA35 and just over a stop slower than the Sigma. It's supposed to be very sharp wide open (ie it's likely sharper at f2 than the Sigma is at f2). Since it's only available used, you'll (perhaps rather obviously) pay less than you would for a new copy of the other lenses.

I tested it & returned it as it was a complete dog wide open being so blurry in the centre (not to mention the eye watering edge blur) as to be unusable.
So I'm back where I started but would still prefer AF operation.

Simon, that square one looks inadequate to me - I would go with the round one as it's deeper.

I would love to see more incisive, thought provoking critiques of photos posted here.

But that's your limitation then and not that of a camera which I thought it was
You thought you read something I didn't say.

[quote:3496ace15f="Anvh"][quote:3496ace15f="wadna"]I use RAW all the time for the flexibility & what I can get out of a file but at sport on 5fps I'm inclined to go with jpg.
What I am unsure about is what your point is Stefan.

I have always thought that JPEG is for experts, and RAW for amateurs and newbies.
It's all about nailing exposure. If you can be confident that you will get the exposure right every time, use JPEG. If not, use RAW.
I use RAW.

6. The reviewer's usage might conform to exactly what the lens is good for and nothing else. In the case of the Sigma 30, low-light portraits, with the subject in the centre, would work a treat. Who cares about soft edges and vignetting then? They are actually bonuses! But one would not want to use it for shots of walls and landscapes -- in these use cases the FA31 would blow it out of the water.
Clearly the edges are softer than the centre and there is vignetting in the corners. Oh...wait, no, there isn't any difference...
I'm sure the FA31 would be nicer. But as it would have cost me FOUR times the price the Sigma did, one would hope so!
