(More customer reviews)Before purchasing my Pentax K100D, I had for years used all three models in the Canon Powershot S-series of "superzoom" fixed-lens cameras (S1, S2 and S3). I like my Pentax digital SLR a lot, but after I purchased it (and sold my Canon) I really missed the Canon's versatility. I have recovered most of that versatility with this Tamron 18-200 DiII lens, which is good at the wide angle end, good in the middle and pretty good at telephoto as well (I like to shoot birds) and which even provides some macro capability. This is now my default all-purpose lens. It's not the best choice for low-light shooting, but if the light's decent or you can use a flash, this is a good lens, takes good photos, and is a very good value. To do noticeably better than this, you will have to pay a lot more and probably give up the versatility, too.
I give the lens a rating of 4 stars rather than 5 simply because, by nature, this is a bit of a compromise lens. If you don't need the versatility - if for example you don't really need focal lengths over 70mm - then you can get a lens with slightly superior image quality for the same price or even less (perhaps much less if you buy used). The Pentax 50-200 may be slightly sharper in the telephoto range. My Sigma 28-70 F2.8 is faster in its range (the Tamron's max aperture is 3.5). And while it's fine for my needs, this lens deserves to be called macro only in a generous sense. But as a total package, it's hard to beat.
