FWIW I noticed the Sigma (with a B+W MRC filter on it) is sometimes prone to flare from off-scene light sources, as shown in these pictures. The fact that the flares are all on the right hand side is a coincidence, but all the flares are confirmed to be from bright street lights just outside the frame. I haven't seen any occurrence of the lens flare in horizontal position.
These shots were all taken hand held, with (near) open aperture (<f/2.5) and the lens hood is on. The camera is gripped but obviously the lens extends beyond the grip. I'm not sure that I like this effect, and it is something I may want to avoid in the future but on the positive side it does have something reminiscent of the anamorphic lens(flare) effect as seen in some movies.
Does anyone recognize this flare, is it something to do with the MRC filter? All of my UV/clear filters are B+W but this is probably the ony one I have with a multi reflective coating (MRC). Cheers.
