Which lens for Pentax K5?

I'm upgrading from the Nikon D70s to the Pentax K5. I've been studying photography for 3 years now and really want a new camera!

The photos I take are usually as close up as possible, so macro 70% of the time. However I do like capturing nice portrait photos which are not as close up. I really like to make the most of my lens and camera. I don't take landscape shots at all really.

These are the lenses i've been considering:

Why is the quality in this picture so bad?

This picture was taken with the kit lens on my Nikon D50, the standard 18-55mm.It was taken at 55mm, f/5.6, shutter 1/160, ISO 400. I'm a beginner photographer, still learning every day. I'm wondering, why is the general quality of this picture so bad?

Which Digital Camera? - 1

I'm stuck between the Nikon D3100 - Digital camera - SLR or the Olympus E-PL1 - Digital camera - mirrorless system. This will be my first "big" camera buy and I'm not sure which one is better. They both seem pretty good. But the Nikon is £100 more… Is it worth the extra money?

Little DSLR experience, need tips for job tomorrow?

Hi there. Tomorrow is my school's Homecoming pep rally and I am in charge of taking photographs. I recently purchased my first DSLR camera, a Nikon D3200. Our gym is like a typical gym, bright fluorescent lightening & many people will be moving around. What is a good setting (like what ISO) for taking photos of moving & stationary people at the pep rally? Thanks in advance!
