Customer Review: Pretty good lens
Not a bad lens considering that you would have to carry two lenses to do the same. The image quality is pretty good for a lens in this range. I’ve read three other ‘professional’ reviews that did more lab type test and they were all pretty impressed with the overall performance, at least they all agreed it was worth the money.
In reference to other reviewers, I didn’t find purple fringing a big problem. It is there, but not as bad as I’ve seen for other cameras. As far as the specks on the lens causing spots in photos, I totally don’t see how that is possible. I sprinkled a dozen or so grains of pepper on my filter in front of the lens and couldn’t see anything at all in the way of spots in the image. It could possibly happen if light was hitting directly on the lens but this seems more like a dust on sensor or bad pixels problem.
I felt the biggest letdown was the vignetting, especially at max zoom. It was quite noticeable in the corners especially in sky shots. You need to stop down to about f11 before it starts to improve.

Customer Review: DA 70mm vs. FA 77mm
A lot of people have a tough time choosing between DA 70mm Limited and the FA 77mm Limited. Both lenses have their merits, but I ended up going with the DA 70mm for a few reasons…

DA 70mm pros:
- Much faster autofocus.
- Much less CA (chromatic aberrations) and purple fringing.
- Much cheaper.
- Still works on film bodies, but you need a body that supports aperture controls.

FA 77mm pros:
- About 1 stop faster (f/1.8 vs f/2.4).
- Has an aperture ring so it works on all Pentax 35mm film bodies as well as digital.
- General consensus that the bokeh is better.
- Slightly longer reach.

Both lenses are sharp and render images beautifully, so as you can see, it really depends on what you want from the lens.

Since I wanted this lens for candid portraits, I needed the much faster autofocus capabilities. I also figured that I wouldn’t shoot at f/1.8 much anyways since I find it difficult to work with such a small depth of field when shooting portraits. While most people find the FA 77mm’s bokeh to be better, the 70mm still produces very pleasing bokeh. It’s just different.

All in all, the DA 70mm seemed like a much better deal to me and I don’t regret buying it over the FA 77mm at all.

 Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens for Pentax and Samsung Digital SLR Cameras  Good quality Versatile Lens
I purchased this lens for my Pentax K10D, and it works quite well. The zoom range is just right for most applications and the semi macro performance is handy. Performance wise it is very sharp, low CA, low vignetting and low distortions. At 17mm the performance sags a little with some distortion and when wide open some vignetting. In most cases I haven’t had a problem. At 17mm, however, the distortion gets pronounced at distances less than 3 feet (1 meter), so take a few steps back if possible. Aluminum construction is nice.
Overall highly recommended!

Sigma 18-50mm f/2.8 EX DC SLD ELD Aspherical Macro Lens for Pentax and Samsung Digital SLR Cameras The Sigma Corporation is pleased to announce the launch of the new 18-50mm F2.8 EX DC MACRO lens. This lens has a large aperture of F2.8 throughout the entire zoom range, a minimum focusing distance of 20cm (7.9..) and a maximum magnification of 1:3, making it ideal for close-up photography. Specially designed to suit the characteristics of digital SLR cameras this lens provides a high level of optical performance. Its design incorporates both glass-mold and hybrid aspherical lens technology which offers extremely high image quality as well as a compact and lightweight construction. Minimal vignetting and superior peripheral brightness is ensured. Special Low Dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass elements provide excellent correction of color aberrations. The super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. High image quality is assured throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood (supplied) plus circular polarizing filters.
Excellent alternative for kit lens
When ordering a Pentax K10D, I didn’t want to spend a fortune on a top notch camera and put a 50$ kit lens on it. The Sigma 18-50mm f/2.8 EX is an excellent alternative, several times more expensive and better than a Pentax kit lens and a few times less expensive (and also a class below) than a Pentax zoom lens (Pentax SMC DA* Series 16-50mm f/2.8 ED AL IF SDM). So this lens kind of fills the gap between Pentax entry level rubbish and Pentax hi-end super-expensive lenses.

I wouldn’t call this a true macro lens, it’s rather near-macro. When zoomed to 50mm, it can focus on objects just 20cm from it, which is excellent for a non-specialised default carry around with me lens.

The build quality is as usual for Sigma EX - top notch. This lens is much more compact than the superb lens Sigma 24-70mm f/2.8 EX they used to make for 25mm film cameras. The most annoying feature of this lens is the focus ring which rotates in autofocus mode. The lens is quite small and when holding the zoom ring while shooting, my fingers often touch the rotating autofocus ring. Please note that 18-50 tanslates to 27-75mm in 35mm terms. If you are a wide angle fan like myself, prepare to look for a second, wide angle lens.

I would recommend this lens for a K10D or a K200D. If K20D is in your price range, consider buying a Pentax SMC DA* Series 16-50mm f/2.8 ED AL IF SDM - possibly the best zoom lens for Pentax digital out there.

Customer Review: The Pentax 16-45mm f4 is a Keeper.
Ditto Dana G’s review. I migrated from a pretty extensive Nikon film system, and have used all kinds of other brands of film camera equipment, either on assignment or as a community college photo instructor during the 70’s and 80’s. I tried a variety of zooms, including varifocals with ELD glass. They were visibly softer than their equivalent single-focal-length counterparts. I noticed this after I had spent a long time using one particular varifocal. One day I switched back to a prime and when the prints came in, WOW! You could even tell with a casual glance at a 3X5 proof, that there was a huge difference. And the wide angle range in those 1970′5 and 80’s zooms alway seemed extra soft and distorted. So I just gave up on zooms until I experienced digital.

I’m not one of those people who photographs charts. But I’ve a LOT of experience looking at real world images. In fact, as long as the lens seems to be working I don’t really pay attention to it. However, in this case, I was shooting some photos of rocks along the Maine coast, from a tripod, and I decided to try to use a few Pentax prime lenses–a 40mm SMCP DA 2.8 and the Pentax FA 50mm 1.4–just to see if zooms had improved. All shots were in the 35-60 mm range, around f5.6-f8. When I uploaded these images into Photoshop, I was flabbergasted. The 16-45 mm gave nicer color and was at least as sharp as the two primes. Since then, I’ve had occasion to compare it against my Pentax DA 14mm 2.8, and I haven’t noticed any real-world difference at the wide range either. But it’s the fact that, if there were a difference, I would have to look really, really hard to see it that impresses me!

I find that I use the !6-45 more than any other lens that I own. I purchased it as an “upgrade” from the kit lens. And, as an aside, the Pentax K10D seems as if it were custom designed for migration from film or prosumer digital. The value for the money in this system is unmatched by any other maker. Amazon’s latest body price=$530 after rebate. Not bad for a camera with shake control, self cleaning ccd’s and the build-quality of a $1,500 Nikon.
