The Sigma 17-70 vs Pentax DA 17-70 debate (again - sorry)

I've just sold my Sigma 17-70 having enjoyed using it over the past months, it's a great lens. Having had a couple of questions regarding why I'd sold it & what has replaced it I though I may aswell creat another thread.

During the past week I've had the chance to tryout the Pentax 17-70 on my new K20D body and here are my thoughts vs the Sigma, nothing scientific just my perceptions..

Sharpness between the 2 is pretty close, if I had to pick a winner it would be the Sigma - I think it's just very slightly sharper

Build quality - I'd give this to the Sigma too, feels a bit more substantial.

Colour/contrast - this is where Pentax definitely wins me over, whilst there's nothing wrong with the sigma there's just something that little bit more striking about the image contrast/colour the Pentax produces

Functionality - the Pentax gets my vote here too, SDM is very nice. I'm not 100% sure but I also got the impression that the SR worked slightly better, although maybe not?

In conclusion I'm very pleased swapping the Sigma for the Pentax, love the colour/contrast & SDM - however I don't think that a full price the Pentax quite justifies itself, the Sigma is definitely a very nice lens.

Just to remind everyone these are just my perceptions so nothing scientific !!

Pentax is now £529.I am so glad i picked one up a couple of weeks ago for £330.This only leaves the 55-300 and 16-45 as bargain lenses now.I would love to hear a convincing argument for the massive price hikes.

I'm not surprised on the comparison.
I too would like the Pentax's SDM (having tried a D40 with kit I was amazed with silence), it would be nice, but its just too expensive (even before the hike) and no one is selling used. I'm also not surprised the Pentax looks better in contrast.

Any-hooo... Got me a Sigma 17-70mm soon , I think I'll be very happy anyway .

Interesting to hear - I guess if the prices are close then the Pentax is definitely worth getting, but with the current increasing gap the Sigma looks like one of the better reasonably priced standard zooms to get for PK fit. Eduardo - I have the Sigma and like it very much - I'm sure you'll be happy too, but pleased that Simon has got a lens he's even happier with...means I'll have to make a future visit back to his website to see the use he'll put it to!

Mr Wu-Hoo, Pentax's marketing man, read an article in the Wall Street Journal, tranlated into Japanese by a person on work-experience, which said that the pound sterling was kaput, and would be worth only 25% of its current value by June 2009.

Being on the ball, Mr Wu-Hoo immediately re-priced all UK-bound inventory, and sat back, expecting to be hailed for his foresight.

Meanwhile, the work-experience chappie was too embarassed to admit that he should have said fall BY 25%, not TO 25%, and when he finds out, Mr Wu-Hoo will keep quiet rather than lose face by admitting it was all a mistake.

By September, the catastrophic fall in Pentax's UK sales will have become apparent to Hoya-San, the head honcho of Hoya, and Mr Wu-Hoo's head will woll (if he doesn't fall on his samurai sword).

By that time, Pentax User will have been reduced to a core of elderly curmudgeons arguing over their twin obsessions - bad English and good Scotch.

Convinced?

Talisker. Without doubt.

Oh, that wasn't the kind of bad English obsession you were talking about was it?...

What do you mean 'reduced to... elderly curmudgeons'? I thought that was all there was to begin with and the only Scotch malt whiskies worth considering are Springbank and The Native Ross-shire. So there.

I would consider Highland Park to be a 'bridge' whisky suitable to those moving from a P&S like The Famous Grouse onto more serious stuff; Talisker is more of an entry level Nikon being a bit rough around the edges without any substantial build quality.

Pentaxians, being a bit different, tend to prefer Islay whiskies.

After much deliberation, I bought a Sigma 17-70 this morning.

Hopefully, if it stops raining, will be trying it out tomorrow
