Bunnahabhain is my ideas of heaven, although a glass of Laphroaig on a winters night is really relaxing. P.s. I have neither lenses but you can't have everything.

Hi,

I've only owned the Pentax 17-70 for a couple of weeks and the weather has limited my chances of using it..these are the only 2 decent shots I've taken with it so far..







I'm sure others could post more samples.


If you're torn between the Sigma/Pentax 17-70 options what I would say is that both are very good lenses and at new prices the Sigma is by far the better "value for money".
However the Pentax does produce nicer colour/contrast (IMHO) and the SDM is a nice addition - I bought my Pentax 17-70 used from on here so if can can find one as a 2nd hand buy I'd go for it !!

I'm completely sold on it now..I'm convinced the colour/contrast is much nicer than the Sigma, here are a few more recent photos - apologies for the watermark but they're hosted on my website

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 !!

Simon

Interestingly, Photozone gave the IQ of the Pentax DA17-70 3.5/5 and the Sigma 3/5 and also said that the build/mechanical quality of the Pentax was 3.5/5 and the Sigma was 3/5. The Sigma did win on price performance as it is cheaper, the Pentax getting 4.5/5 and the Sigma 5/5.

I now have the DA17-70 and think it is a superb all round zoom, just like the DA16-45 with an extra 25mm at the long end.

The Sigma or the Pentax one? For the Pentax one visit the Pentax Gallery website and do a lens-search.

I have just purchased the Sigma 17-70. Not used it much yet but I like the macro facility.

I looked at both lenses but just couldn't justify nearly double the price for the Pentax - it simply cannot be twice as good, although I would have loved to purchase a Pentax and also the SDM focusing.

I am hoping the money saved will go a long way to purchasing the forecast 1.4x SDM converter which is supposed to be on the cards!

Hi All,
Not posted before but finding this discussion particularly useful right now as I'm having this exact dilemma. Just need a bit more of an all-purpose walk about lens for when with the kids and out on Dartmoor etc, would love the pentax but just can't believe it is worth twice the sigma. Also fortunate enough to have the FA 43 and 77 if I think I will need that special pentax magic. Don't think the 16-45 will have the reach and it sounds like folk are generally pretty happy with the sigma, right then where's the wallet!

By the way Ardberg gets my vote too!

I agree, having owned both the Pentax definitely isn't worth twice the price, I bought my Pentax 2nd hand for a decent price..I certainly wouldn't have swapped the Sigma for it had I needed to pay the full list price...the Sigma is an excellent lens & you won't be disappointed

Thanks Simon, have ordered it today and hope to get out with it at the weekend - what's the betting this lovely autumnal weather comes to an end as soon as it arrives!
