I ran into David Bailey - yes, that one - yesterday in central London at the Camera Cafe in Museum Street*. We have some ancient, trivial, history. He was carrying a Panasonic GF3 with an external viewfinder and the Panasonic 20mm 1.7. I had the OMD with me with the identical lens mounted. He was extremely enthusiastic about the GF3 - and particularly on its focus speed, which surprised me a bit being used to the same lens on the Olympus camera and on cdf generally. He hadn't seen the OMD before and immediately assumed that it was a DSLR. When I let him try it with the same lens he was disdainful of the focus speed - and this was in summer daylight. So I mounted the Oly 45 1.8 which restored the OMD's credibility a bit.
I think it's interesting that a photographer of Bailey's status would be wandering about the West End with a GF3/20 1.7 dangling off his neck when every tourist you see that isn't using a cellphone camera or a compact seems to be lugging a DSLR around these days.
He was also very dismissive of Leica, having tried all the digital bodies. And he remarked to one of his assistants, who was interested in some Nikon zooms, that he'd "never used a zoom in his life."
*Recommended for a visit if you're near the British Museum - excellent noodles and an interesting selection of used pro hardware.
