Good Wide Angle Zoom?

My wife and I each have k10ds and we love them. Currently we primarily use the Tamron 18-250mm and the Pentax 50mm 1.8 for available light shooting. We're looking for a wide-angle zoom that will not break the bank and yet deliver reasonably crisp shots with a minimum of purple fringing. Any suggestions would be appreciated.

Hi James.
How wide do you need it?
The wider, the costlier it is...
I would suggest the Pentax DA 16-45, which is a little wider than the Tamron you have, but being a Pentax lens there will be some (not excessive) purple fringing in high contrast situations (very few lenses produce no purple fringing on digital SLR cameras, as it's mainly a feature of the camera as opposed to CA, which is a feature of the lens).

Otherise, if you like Tamron the 17-50 produced by them is excellent. Any wider, and you're looking at significantly more expensive ultra-wides like the Pentax DA 12-24, but the Sigma 10-20 may still be within your budget...

DA12-24/4 is out then cos PF is its major weakness. It has great sharpness however.

Honestly when I had my 12-24 I didn't notice much purple fringing. Anyway, you could try picking up a 10-20 Sigma locally used for a great price.

Thank you, All, for your replies. They've been great help since I was quite confused as to which direction to go. I'll study these lenses before making any decision.

I recommend DA 16-45mm.

I have the 16-45 and a kit 18-55...both are fine..but the 16-45 is better. I recommend the 16-45.

I haven't used a 16-45 but I can recommend the 16-50 and 12-24. I keep an eye on eekBay for used lenses and there a few there now, including a 16-45 for $200.00.

I am surprised everyone is suggesting the 16-45.

the OPis asking for wide angle, wider than the present 18-250.

16 is not a big change,.

I would suggest looking at sigma both 10-20 and 12-24 as well as the pentax 12-24 and tamron 10-24.

These are WIDE angle zooms

16-50 is more expensive, heavier, proned to bad CA (purple fringing) , also several bad copies around (look for the 16-50 bad copies serial database, sticky thread in the lens section). and has no superiority over the 16-45 in resolution and color rendition. It's only superiority is it's 1.5 stop faster oh also it's WR. Pick your choice.

Oh yes, 2 mm difference is huge, at least to me. I still keep the 18-55 kit lens, 16mm is what would I call as "wide" .

These are ultra-wides. Suggestions have been made for the 12-24 and 10-20 - but it *sounds* like from the OP that these may be beyond his budget?

Being a fish eye lens, it's less applicable to the variety of settings available, and it suffers quite shocking PF.

The 18-250 is a decent lens which is very capable of capaturing very nice, sharp, clear photos. I have one, not had any problems with fringing, thankfully...but in those cases where I need to remove fringing, Lightroom seems to clear that up very well.

Which PP software do you use?
