When I bought my K100D w/18-55 years ago, the first lens I purchased was the Tamron 70-300. Despite the slow AF and extreme PF, I had much fun with it, and especially the 1:2 "macro" feature. After I bought a K2000D, I sold the Tamron and bought a Pentax 80-320... which was a mistake, as it was soft with poor contrast. I sold
that and re-acquired a Tammy 70-300. I eventually sold the Tammy along with my K2000D and acquired a Pentax K-x and a DA L 55-300. The 55-300 had better contrast and color and wide-open sharpness than the Tammy, and of course it went wider. However, after over a year of use, I was really missing the Tamron's 1:2 pseudo-macro, and for some reason never attained a true state of happiness with it... so I sold the 55-300 and bought a Quantaray 70-300, which is the Tammy in cheaper clothes. In spite of the return of the PF monster, I feel like I've been reunited with an old friend.
Anyone else have a lens - cheapie or not - that feels like an old friend?
