Hi, I have been using a Nikon D70s for 5 years and have been really happy with it, but it was stolen with the lens I most used. I bought a minimal second hand kit (Olympus e500 with kit lens) because I was abroad when my camera was stolen, but now I'd like to improve my system . As I don't have a high amount of gear invested in either system, I have been considering different brands, and I've found the Pentax system quite interesting quality wise and at a reasonable cost. I've been looking at different combinations to start up. I mainly use standard and wideangle lengths (I previously had a 17-35mm 2,8-4 and a 50mm 1.8, which suited my style quite well). This is my projected set-up: - Pentax k20d: I find this body quite interesting and the build quality seems to be really high. - Tamron 17-50mm 2.8: I prefer to spend a bit more over the standard kit lens in a larger aperture lens, as I like to take photos in available light. I have read quite good reviews about this lens, and combined with the SR and the quite good high ISO performance (yes, I'm aware of the so called banding, but I don't find it to be such a big problem in the k20d) it should be really interesting. - Tamron or Sigma 70-300: I don't use these focal lengths so often, so I feel any of these lenses should suit my needs. I have looked at the Pentax 55-300, but I think it is quite expensive to the use I'll give to it. However, I could sell the Tamron/Sigma in the future in order to buy that lens if I don't feel confortable with it. So, what do you think about my "project"? I am willing to start using whatever I decide to buy now that the weather starts to become better! Thanks for reading and any suggestions are really welcome.
