Great shots Pea-n-Me, I hope you enjoying the 510 still... I love the pier shot, and the last sunset shot in that post.
I think Code mentioned earlier he had an extra lens or two that he enjoys.
The lenses I have beyond the 2 kit lenses are the Olympus Zuiko 11-22mm f/2.8-3.5 and the Sigma 30mm f/1.4.
I bought the 11-22 f/2.8-3.5 used for $600 and it is a FANTASTIC lens, and an even better value when you compare to other brands fast wide zooms ($1250+). Also, image stabilization isn't available in any brand's wide lenses so the fast wide angle + in-body stabilization is a really awesome combo. Image stabilization isn't as effective in general at the wide end but still about 2/3rd to 1 stop advantage which is definitely significant. I have sharp shots down to 1/2 sec handheld

Here is an example of a 1/2 sec shot, along with a some other 11-22 shots from our January trip, mostly stuff I've already posted elsewhere (picture of the day thread, my trip report, etc)...
The Sigma 30mm f/1.4 has gotten very popular on this board, and I love it. (Paid $400 new) It is definitely my most used lens as I like to shoot our evening family gatherings in natural light. My copy had a significant front-focusing problem (common in this lens) that I didn't notice at first, but after a trip to the factory is works well. This is another lens that really benefits from in-body image stabilization, as there is no such thing as a stabilized prime in any system. Some more samples, stuff I've already got uploaded...
I was recently pondering if I was going to stick with 4/3rds for the long haul and decided that I was, but my goal before our next trip is to upgrade to the E-3 (working hard on the DW for this one

). Also I have a wish list of lenses, it goes like this:
- Olympus 50-200 f/2.8-3.5, ~$625 used
- Macro lens, either Olympus 50mm f/2.0 or Sigma 105mm f/2.8, ~$325 used
- Olympus 14-54 f/2.8-3.5, ~$300 used
- Lensbaby for 4/3rds, $384 new
Also looking to get an Oly FL-50 flash
There are hundreds of pics from our Sept 07 trip in my trip report (link in my sig), and hundreds more to come from that trip and Jan 08.
