Pentax 16-45mm f/4 ED AL SMC P-DA

This lens is fantastic, it is the "must have lens" on the K10 and the k20. Really spectacular. I think the only reasonable alternatives are the new tamron and Sigma but they lacks in colour and aren't 16mm!

These days the old DA 16-45 f4 is getting strong competition - the Tamron 17-50 f2.8 with Pentaxmount, the new Pentax 16-50 f2.8 and Sigma EX DC 18-50 f2.8 macro - they are all quiet better in the optics and buildings.... the DA 16-45 is really NOT a...

This is a significantly better lens compared to the Pentax 18-55 kit lens, which itself is pretty good for a kit lens. Quite good optically except for chromatic aberration correctable in Photoshop.

I bought this lens on eBAY noting it was supposed to have been used only a couple of times. When received, it was in like new condition. I have only had this lens for a couple of weeks at this writing and so far I like it very well. Like many users...

This truly a great piece of lens, consider getting this lens with the K10D body instead of the kit lens. You get much wider angle at 16mm and constant F/4. I tried several close up shots even though this lens wasn't meant for close ups it still produce...

Ok this lens is great kit lens.

This is my main lens and covers my favorite ranges. it gives really good quality images and has a nice grippy zoom ring. Like most modern lenses it's a little too plasticky feeling for my tastes, but seems well made.

This is a must have lens for any Pentax users. It is a very sharp lens with an excellent wide angle zoom range. Flare is VERY well controlled as well, this lens easily has the best flare performance of any lens I have used.

Although the focus ring is at the front of the lens, it does not rotate when focusing. Circular Polarizers and Gradient Filters, as well as the included lens shade, work just find with the lens.

This is a much better choice for the Pentax pro digitals than the kit lens that is usually bundled. It's a constant apeture zoom, and stays sharp even when opened wide.
