Thank you both. I have been under the impression previously that 4/3 system lack a bit compared to aps-c system. But when I now compare with Oly's top model I have to reconsider, at least up to 3200 ISO. As for walk about, this is especially with quality prime lenses, a delight to use and also with its stabilisation in the camera when using old lenses of different brands with dedicated adapters. I shan't elaborate on this too much, but its fun when one can use a Pentax 50mm/f1,7 and a Nikon 105mm/f2,5 on it and have stabilisation. And as for me, eye sight even being as young as I am, may att times be problematic. In this camera, by pressing a button on top, I get a hundred % enlargement in the viewfinder or on the display if preferred. Just great. Enough of commercial. But if any are looking in the direction of Olympus OMD-EM1, launched 2 years ago, I can heartily recommend it, and as mark ll has come about, the EM1 has dropped in price. Take care everyone. And may I ad, when I also see Julian's superb series from the swim in Penanze, done with an om5, I am totally convinced. No comparison though.
