Somebody asked me today to recommend a new lens for an old Canon 10D camera. He wanted a lighter version of the one he had for general outdoor photography. I asked him if it had to be a lens for this ageing camera and he answered with a no. What I did recommend was this combination of an Olymus E-PL1 and the mZD 14-150 lens. I seem to have taken this combination with me on vacation quite a few times and it has always given me pleasant images. I'm really pleased with this combination. However, wheather he takes my advice is another question altogether.
BTW, these can be has on ebay for a pittance, and for those who are thinking about something like this, go for it. A refurbished unit plus the lens will cost you no more than a €250.
