 Tremendous lens, a bargin compared to... |
| Review Date: November 25, 2007 |
| Reviewer: Hiram Grant, |
If you've read my previous reviews, you know that I'm a retail camera salesperson. I get to use a wide variety of equipment, but I'm a bit picky on what I buy myself. I own this lens.
I couldn't be more pleased with this lens for my K10D. The images are crisp at all focal lengths and apertures. The focusing is both fast and smooth. (Note: it will require updating to firmware version 1.3 for the K10D to autofocus properly.) Build quality is top-notch, and the weather-proofing is nice, although I doubt I'll test that often.
Pentax has also equiped this lens with the older drive system, so that it can be used on older digital cameras, but the noise level goes up, and the AF performance, while decent, goes down.
This is an amazingly good deal compared to either the Canon or Nikon lenses in the same range. The Nikon has about the same build quality, but costs considerably more. The Canon has the IS system built into the lens (not necessary with Pentax); therefore, it costs about the same as the Nikon. A very good lens, it still doesn't have the build quality "feel" of the Pentax nor Nikon. Additionally, the 16mm makes the Pentax a bit wider, a big advantage for my type of shooting.
Simply put, without this lens, I'd be shooting Nikon. |
EXCELLENT LENS TO OWN

Best walk around lens to own. With a K10D, you can have a weather proof combo for around $1,350. Where else can you find this kind of deal? If you add on a DA 50~135 with them, you can have an award winning camera with lenses range from 16~135 f2.8 for $2,100.
Both of these lenses have EXCELLENT SHARPNESS and BOKEH. DA 50~135 has "cleaner" picture though.
These are my 2 favorite lenses now. period.
If you want to buy something that is worth every penny, the combo I have listed above will do!!! |
A bargain...just buy it!!!

For Pentax K20D users:
(Older model owners: upgrade already, you're missing all the fun, what are you waiting for? ;-)
I reviewed tons of sites before purchasing this lens. Here the lowdown after some extensive K20D (real world studio with people, not charts) testing:
-"Famous urban Internet legend" QA issues: Are done and over with. Blast from the (2008) past. All current lenses in stock do not have any issues anymore (in case you heard).
-Sharpness/Focus: Much, much better then lower grade zooms, especially if you stop down an f-stop or two (which you really should anyhow). It really shows all the (detailed) glory of your sensor. Do not settle for a third party lens (Sigma, Tamron, etc.) if you can have the real thing.
-AF: Way more accurate then kit/consumer lenses. Dead-on 95% of the time (versus non * lenses: More like 50%-70%). And in case you're comparing: Yes, it's better then the 17-70mm Pentax.
-A real bargain compared to Nikon/Canon glass: you would have to pay over a grand for the same quality.
-Bottom line: the best zoom glass you can get other then the (new digital) * primes. Even there, I think you would have a hard time to see a difference.
And yes, I do this for a living (shooting, not reviewing, that is).
I'm just flabbergasted how professional Pentax has become: The Nikon D300 with any glass shoots like a Coolpix in comparison (yes, I own an entire Nikon outfit). |
Great all-around lens

Pros:
- Build quality is excellent
- Weather sealed
- Very sharp from F/4 across the entire zoom range
- Great colour rendition
- SDM works as advertised: fast and quiet
Cons:
- A tad soft at 16mm F/2.8

Excellent lens

| Review Date: March 25, 2009 |

The Pentax DA* 16-50mm is a lens that I have wanted for sometimes, but have avoided getting because of numerous comments about Quality Control issues in its manufacture. Finally, I could resist no longer and purchased the lens.
It is a solidly built lens. While it is nearly the same weight as its big brother, the DA* 50-135, it handles a lot better due to being much shorter. The zoom action is very smooth and the auto focus is quite rapid.
From a photo stand point, the lens seems quite sharp. At 16 mm and f2.8, it is less sharp at the edges, but still has good center sharpness. Others have commented about vignetting at 16 mm and wide open as well, but I have not noticed any issues with my copy.
The most amazing thing about this lens is the contrast and color rendition. I feel as though this lens is able to render scenes in ways that make them 'pop,' even when there isn't anything particularly special about the scene. If you don't need f2.8, then probably go for the 16-45 f4.0; otherwise I highly recommend this lens. |
Great lens

| A great wide to standard zoom lens. It is fast, sharp, and has an extremely rugged build. It is definitely a large, heavy lens compared to the DA 18-55MM, for example. On the other hand, the weather sealing is evident and the focusing ring is large. The SDM is virtually silent, quick, and silky smooth. Overall this lens is well worth the investment. |
Great Lens!

I've been using the Sigma 18-50mm f2.8, and upgraded to the Pentax because of the SDM, the wider wide angle, and the Weather Resistance, and I don't regret it. The Sigma isn't a bad lens, considering it costs ~60% as much, but this lens is far superior.
Initially, I thought it was broken - when I pressed the shutter button I didn't hear *anything*. Then I realized that it had focused, and was amazed. It's much faster focusing than my other short zooms, nearly silent, and very precise. Contrast is great, bokeh is very nice. It also focuses closer than I expected - down to around four or six inches. Not a Macro, but definitely useable for lots of close-ups.
The images I've gotten from it in the days I have had it are extremely sharp and contrasty. The Sigma I have tended to underexpose by about half a stop; this one seems dead on.
This thing is huge, too. It's probably 30% bigger than the Sigma, and much heavier. Prepare to spend money if you want to put filters on this baby. Make sure you have a good strong back before strapping this thing on your camera, too!
Pentax continues to amaze me with the quality they produce at such low prices. If you're one of the people that just snorted when I said "Low prices", I suggest you go check the price on the Nikkor or Canon equivalent of this lens (L series in Canon lenses). Then report back. |
Fabulous Lens

| This lens produces excellent contrast and color rendition. The weather-resistant sealing really works, as the lens held up in wet (Colorado River) and dusty (Antelope Canyon, Arizona) conditions. There is, however, a QC issue as it took me a few returns before I got a keeper. This lens is so good, it was worth a little hassle. |
Stunning lens

It's too bad there are bad copies out there because the only thing thing I can say about my copy is "stunning." Well, there are other adjectives but you get the idea;)
I've had mine for a little over a month now and it's by far my favorite lens. Crystal clear sharpness, incredible colors, great bokeh, and wonderful contrast. For me it's the perfect walkaround lens--although I wouldn't mind getting my hands on a 31mm Limited!
My copy does have very, very slight vignetting at 16mm at 2.8 but it's never been annoying, but it can be easily PP'd out if need be. I didn't mark it down for this because it is so slight and is actually pleasing to the eye, imo.
One thing, however, is you should buy it from a reputable dealer with a good return policy so if you do get a bad one it won't be a hassle to return it. I have to say, though, that this lens is so good it's worth taking the risk. |
Fantastic lens!!!

This is very very nice lens!
I was little bit hesitant to buy it mainly because of the QC problem
However I'm so happy to get this one and want to encourage anyone to try it.
For this price tag of $650, this is a steal.
Very very sharp lens at the price of Nikon or Canon bundle.
Just get it, you will never gonna lose it. |
