Anything I should be concerned about? It's a second-hand Sigma 85mm f/1.4 HSM on Canon 5D Mark II. Cheers! Zexun

Mike ugly when I'm sober  More info | Jan 12, 2012 09:04 | #3 Must be something there somewhere. Checked the rear element of your lens? I doubt it would be on your sensor as at this aperture gunk on the sensor would have to be huge to show up and as it is in every highlight it also confirms that it is not the sensor. www.mikegreenphotography.co.uk

yogestee "my posts can be a little colourful"  More info | Try shooting a blank light coloured wall at different aperture setting, ensuring there are no highlights. Try a few shots where the wall is OOF. Jurgen

ZoneV Goldmember More info | Jan 13, 2012 09:49 | #7 I would suppose this could be a hair inside the lens, near the iris blades. Or probably something on a lens in the near the iris. Worst case could even be a crack in a hybrid aspheric lens, or a kind of scratch there. Look at the wolly bokeh of some of the Samyang 85/1.4, I suppose that is caused by not very good molded hybrid lens. DIY-Homepage
