This is horrible!. How can you be expected to produce fine images with such hor rendous cleaning marks on your lens? Please send this monster to me immediately and I will make sure it receives a proper burial.... right inside my camera pac k. Please be sure to also include a Zone VI 8x10 lensboard with it. As far as computar symmatrigons are concerned - I think a good virus program wil l be able to eliminate them from your computar.
