I have had a Pentax 6x7 for a very long time with a whole group of lens for that camera. I just got the Pentax K100D, a digital body that will take my 6x7 lens. I am looking for a good all propose lens that was designed for a digital camera. I don't take many zoom shots, I prefer normal to wide angle ones. A guy at the camera store is trying to sell me on Tamaron 18-200. I don't know much about Tamaron. Any suggestions? Is a fixed lens going to be better or is a zoom with a shorter range going to still get good results?
