No Blooming or White Disc problems with my X10.I am a scientific.biological photographer with over 36 years experience in cameras, optics, macro, micro and digital imaging systems, etc. I have followed this discussion and have owned an X10 for several months now, as a walk around pocket camera. I have not had a blooming or white dics problem, nor have I been able to create the problems if tried. I have extensively test the X10 against my main Canon 5D Mk II and Canon 40D with a variety of lenses and in many low light and super highlight situations. I have no more blooming with the X10 under extreme conditions than with the DSLR Canons. Otherwise the X10 is a great camera, vey well made, good exposures, great sharp lens and excellent IQ. So, I guess I am a lucky SOB or perhaps some of the X10's made it though the quality control gate in good shape. I will be interested to see how the 'X20' compares.
