Oh, the great thing about 1.4 lenses is you don't need a flash - but smaller apertures get weird because the depth of focus gets really short, so you have to learn out how to deal with that. Example: with a 1.4 lens if you focus on the G key on your keyboard the T and B keys will be out of focus. Some 1.4 lenses have back/front focus issues, where you focus on G but the picture is actually focused on T (back focus) or B (front focus). This gets more complicated the further away you are from your subject, since the DoF will be small; you might accidentally focus on someone's nose instead of their chin, etc. OTOH you can take great pictures with a 1.4 in 1 lumen (essentially 1 candle).
