After alot of reading these past hours and looking at samples of what some different lenses can perform I'm pretty sure I'll go with the
Tamron Macro SP AF28-75mm F/2.8 XR Di LD, it looks like a very nice allaround lens for the things I enjoy taking shots of(atleast from what I've seen).
As wideangel and for alot of landscape photography and such I will then get myself a , I will later this week order a Sigma EX 10-20/4,0-5,6 DC in the near future, together with somekind of cheap telezoom just becuse I want to try it out.
Anyone got some input if this could be a pritty good way to start? I'm mostly making my decision based on what I've seen them done, and I've really liked the results. The 28-75 tamron looks to fill my needs as a everyday lins with good portrait capabilites, decent for everything else and a macro function just to play around with.
