I have just sold a Canon DSLR and 3 Canon L series lenses to fund the purchase of a lighter, interchangeable lens camera. The 'problem' with Canon's L series lenses is that the results are so good, you are spoiled for using anything else. Initially I bought a Canon 550D and Canon EF-S 18-135mm zoom, but the results were so disappointing that, for the first time in my life, I sent the camera and lens back to the supplier. I had been considering a Panasonic GF1 but had initially been put off by the lack of an eyelevel viewfinder; however, on the basis of David Clapp's 'GF1 in the landscape' article ([...]) I bought a GF1 with the 14-45mm zoom and the optional EVF electronic viewfinder. The inital results are very promising; to my surprise, far better than the 550D (which was very well reviewed). My options for a mid-long zoom were Panasonic's 45-200mm or their 14-140mm which was designed to go with the videocentric GH1. On the basis of multiple reviews I opted for the 14-140, and I am very happy. The GF1 is not an 'action camera', the G2 would be a better choice for moving targets, but setting the GF1 to continuous focus and motor drive, the results with this lens are very impressive. Normal photos, i.e. not of moving targets, are beautifully sharp, even at full zoom in dull conditions, so the OIS lens stabilisation obviously works well. Bottom line: not cheap, but great results. An excellent travel camera (particularly when matched with Panasonic's 7-14mm) which I am looking forward to taking to Arizona next year.
