**I think I posted this is the wrong area the first time, so I'll try here :idea: **
First of all- I just wanted to say hi! I'm new here, and hope to get to chat with everybody!
Second of all- I'm shopping for my first SLR. I was at a camera store today and found these 2 cameras that I was interested in. The Pentax was on sale for $250. It seemed nice, but i'm not sure if I liked the look of it. Something about it bugged me. The Olympus was really nice and was $450 for the camera and 2 lenses. I really liked the camera, but since I'm new to SLRs, I'm worried that I won't be able to learn it.
The camara I want needs to be able to shoot a WIDE variety of styles. I've been shooting landscape for a little while now, and want to start into newborn/children, bands, and weddings. But I also want to do macro. So I want something thats versitile and can work multiple duties.
If you wouldn't recommend either of these, is there another you'd think would be better for me just learning the SLRs?
I've been using my older Olympus Camedia 3040Zoom and its one of the regular digitals that I really like using~ but its on its way out.
