Help with Standard Zoom selection - Input Appreciated

It's time to get rid of the brave 18-55 kit lens and get a permanent solution for my regular-use lens but I can't seem to figure out which way to go.


$339.95 = Pentax SMCPDA 16-45mm Zoom f/4.0 ED/AL 28cm 365g 1:3.8
+ Pentax glass quality
+ Quick shift focus
++ Great feedback among pentaxian
++ 16mm wide
+ Good Price
- No macro
- 45mm kinda short


$369.00 = Sigma 17-70mm f/2.8-4.5 DC IF Macro 20cm 455gr 1:2.3
++ GREAT zoom range
+ Nice aperture at wide
+ Nice macro
- Not EX quality


$419.00 = Sigma 18-50mm f/2.8 EX DC SLD ELD Aspherical Macro 20cm 450g 1:3
++ f/2.8 all around
+ EX quality
+ Macro
- Okay range



I like the Pentax features and I wanted to support the branc, but I feel like both sigmas are better valued (though more expansive). The 17-70 has a GREAT range for the everyday pictures while the 18-50 has the EX quality and nice aperture.

Ohh geeez.. why not make a 17-70 f/2.8 EX ELD ??



Any thoughts welcome, and anyone that worked with both sigmas and give me inputs will get a HUG from me!

I'm with you in the same boat, I wish the 17-70 was a constant 2.8, but at the same time, I haven't found the variable aperture to be a big issue. I think it's the most versatile lens of the 3 and that's why I got it.

HTH,
Heather

I'm more inclined to go between either the 'tax or the 17-70. 2.8 @ 50mm is not that big a deal to me, IMO. 4.5 is still quite a good aperture at 50mm.

I'd probably go with the Pentax 16-45, for the wideangle coverage, quickshift, and reasonable pricing.

So I take you are content with the 17-70, correct? And yes, it is the most versatile of the 3 and that counts a lot. And even if not 2.8 constant, at least EX quality would be great... cause I am looking for a replacement that should be kept for a few years...


And Heather, you have the same 3 lenses I want to end up with: 17-70 (maybe), 55-300 and the DA35mm!! It does seem like I did my homework alright, because if another reputable pentaxian is using it, it must be some good!

I keep hearing good things about the Sigma 17-70mm ... although I am waiting to see more reviews on the Tamron 17-50 f/2.8 though ... the only one I have seen seems to have been a fault with the lens though.

I have the Pentax 16-45mm and it's great and is currently my main walk around lens. For the money is one of thoes lenses that's hard to beat. That said I think the Sigma 17-70mm would give you more flexibility and I've hear excellent things about it. Sometimes I wish I had a little more reach in one zoom. But, to compansate I carry my 77mm and 135mm (31 mm if I'm indoors) primes for a nice little travel kit.

yeah, i've seen a lot of GREAT input on the 16-45 and it is a good value ($$) too.... but it has limits like zoom coverage, macro and others..

Macro is a respectable ~0.3x magnification. Not bad, considering it really isn't a macro lens.

Why not wait for the Pentax 17-70 with SDM focusing?

I had the same question about 6 months ago. I decided to go with the DA 16-45. I have not regretted my choice for one second. I can't speak for the Sigma 17-70, but the DA 16-45 is my favorite lens.

that could totally be an option... but the word SDM rings $$$ and I have the impression it'd cost more than $500


Maybe I am wrong on the cost, anyone knows where it should be in the market? and when is supposed to be out?

Did you consider Tamron 17-50/2.8? I handled it once and it feels good. Manual focusing is smooth and oriented the same way as Pentax lenses. Can't say nothing about the pictures, but I hear it's getting good reviews.
I have the Sigma 18-50/2.8 DC EX (non macro). The focusing in manual mode wasn't smooth to start with and now it's really sticky. Focusing ring also tends to stick to the zoom ring and in vertical position lens creeps in/out especially when focusing (focus tends to stick to zoom remember). I liked the finish of the lens until I had to clean it, now I prefer shiny plastic or even better metal. I am still satisfied with pictures it makes thou. They are definitely better than with kit.

Of the three you mention, Sigma 17-70 all the way.
