I asked this question some months ago on a beautiful X10 blog on Flickr. I received hundred of replies, all differents in the point of view. The question is: can the X10 be used in professional use, for istance as a backup camera during a wedding? Many people think not. After some months of use, I can tell YES, by sure. I used it for several professional services, also in situations where a more intrusive, noisy camera would have been impossible to use, like some concert in an ambassade and so on. There are also some guys that use it for professional war reportages, and the director of Magnum photo itself use only compact cameras. Please, tell me yours, I would be pleased to know how many of us use this little gem for their professional work. I think it is a reliable tool at least as many DSLR, and most of the time more practical. Thanks!!
