The thing about this lens is that flare levels are extremely low wide open. I haven't figured out what exactly causes this flare problem at around 5.6, but if the sun (or other bright area) is just out of the picture it can get quite bad; if the sun shines through the hole in the hood, the flare is at its worst. I was talking last week about this with Tom Abrahamsson, and he has noticed exactly the same phenomenon with his lens. Turning the hood 180 degrees is not what one should have to do with a $100 lens hood. Not that other camera companies are immune to putting out idiot products, but Leica, with its relatively small size, puts out a number of them. The finders for the wider lenses spring readily to mind. * Henning J. Wulff /|\ Wulff Photography & Design /###\ henningw@archiphoto.com |[ ]| http://www.archiphoto.com
