Nowadays (among other projects) I'm shooting candle lights in churches (using mostly long exposures) using a Canon 17-40mm F4. (A small part of) The results are here.
I'm thinking now to buy a Tokina AT-X 16-28 F2.8 mostly because it gives me:
- One stop faster
- Much lower distortion
...but I'm concerned on how much the Tokina lens are flare resistant in the above situations (shooting candles & other light sources in a dark environment - see the link) and will not give me different green 'aliens', ghosting or any other artifacts in a much more percentage compared with Canon 17-40 F4. Perhaps I should note that I use a Canon FF camera.
