	imagen de tamaño APS-C Los lentes que crean imágenes de tamaño APS-C se diseñan sólo para cámaras digitales. No se pueden usar en cámaras que tienen un sensor de imagen más grande que el formato APS-C. Estos lentes tampoco son adecuados para cámaras de película. Sin AF Ultrasónico Los lentes con mecanismo de enfoque ultrasónico en general son más silenciosos y rápidos que los lentes de enfoque tradicional. No se usa elemento de lente de Baja Dispersión Los elementos de lente de Baja Dispersión tienden a reducir la aberración cromática. Sin estabilizador La estabilización de imagen ayuda a reducir el difuminado causado por el movimiento de la mano, especialmente con una longitud focal grande o en situaciones con poca luz. La estabilización de imagen puede dar una ventaja de 1 a 3 paradas sobre lentes sin estabilización, basado en la regla de reciprocidad.

Very good kit lens

8 de March de 2007

I bought my K100D bundled with this kit lens and took it around Europe for two weeks. I found it to be very light and easy to use. The provided lens hood works great for protecting the lens, and it's reversible when you don't want to use it. When the hood is reversed, most of the lens barrel is covered, so you can't reach the focus ring, but that's not really a fault. On a related note, the focusing ring feels very loose, but that's probably because this is an auto-focus lens.

I found that the 18mm wide end was usually good enough to get a picture of a medium to large room. The 55mm end felt a little too short at times, but Pentax also makes a 50-200mm lens that goes really well with this one. I found that I rarely need a very long telephoto zoom though, so this lens worked very well for me.

Both the 18-55mm and the 50-200mm lenses use 52mm diameter filters so you don't have to buy another set.

Some people have found that the focus ring on the 18-55mm and 50-200mm lenses feel unsmooth, like there's sand trapped inside the lens. From what I've read, this seems to be a pretty common thing. Both of my lenses have this issue, but it hasn't affected their performance at all. The only time that I notice the grittiness is when I switch to manual focus.

Overall, I think this is a good lens, especially for the price. It can be pretty sharp at smaller apertures, and reasonably sharp wide open.

Excellent kit lens: Give it a try first

I have switched to pentax from canon. Well canon is sure good with a large collection of lenses but pentax gave me somehting better like image stabilization in the body so any lens used becomes IS. I ordered the camera from Beach Camera through the Amazon.com. The service was wonderful and so were the sales support.

I got this lens as a kit lens with my K100D. I was looking for buying a Sigma f2.8 18-50mm. But after reading many reviews of the kit lens, i decided to give it a try first. I am happy i did it. The lens performs great between 24mm-50mm with an aperture fo f 8 or f 11. They are sharp the colours are acurate. While comparing prints (7x5 ") i cant find difference between the pentax kit lens and a prime 50mm f:1.7 on the canon Rebel. There is some difference at same apertures at very large prints. (but how many of us who are not professionals or take regular printouts will go for prints size more than A4 or 11x8.5 inches) I am sure you would like this lens after you try it out......it is perfect for a carrry around lens, you wont be dissapointed.

To summarize.
Pros:
Light in weight and small
very useful zoom range
Great pictures at around 24-50mm (f8-f11)
can move from auto to manual focus immediately
Not seen any ghosting or flare till now
Auto focus accurate
Smooth zooming
Works wonderful for macro shots (of course not comparing it to the true macros)
And all of this you get in under 100$.

Cons:
Vigenneting at 18 mm
soft and unsharp edges at 18mm
5,6 at the 55mm is not sharp.
not good for indoor shots where flash is prohibited.

In fact i have to think a lot to find out any more negatives about this lens.

This kit lens has taught me that :that a kit lens is NOT always bad. try this out first. A great lens will be very costly and buying a great lens will not give me great shots. It is you who can give you some good shots even with this cheap and great lens. if you get to know how to compose good photos.
happy shooting ....:)

A very good lens

16 de January de 2007

The basic kit lens for the *ist DL/DS and the K100/110D, this is very serviceable lens. Is isn't perfect: it gives a few issues at the extremes, and has just a small amount of play, rather than being 'tight' like more mainstream lenses from Pentax. Nonetheless, it is a very good kit lens, and its light weight and overall utility make it a handy general purpose lens.

The ultimate value. The best "kit" lens by far ...

2 de July de 2007

It's pretty universal, Pentax's DA 18-55mm f/3.5-5.6 AL "kit" lens is pretty much the best kit lens out there. Although it still leaves much to be desired, it does what it does for the price, and outclasses virtually all other dSLR vendor "kit" lenses on their bodies. I skipped this lens with my K100D and was planning on buying the much more expensive DA 16-45mm f/4.0. But after reading reviews on the select issues with the DA 16-45 (which is still a good lens overall, don't get me wrong), I decided to buy this lens and wait on the DA 17-70mm planned for 2008. Note that I use the Pentax AF 28-105mm f/4.0-5.6 as my default lens, and a Zenitar FE 16mm f/2.8 as my ultra-wide angle lens, so this lens doesn't see much action.

But for when I want a solid, basic image quality around 24mm, with the option of going slightly wider (with softness on the corners) or somewhat longer (with excellent IQ), I put this sucker on my K100D, often with a 52mm Hoya circular polarizer filter.

This lens, which was designed to go with my Pentax K110D camera works well with it and I am impressed with it light weight. I havent used it enough to make a definitive statement about it's pictures, but at first look they appear a little darker than those made on the same camera with my old, compatable Pentax lenses.
