I am looking for a recommendation for a small, flare resistant wide-angle lens (anything up to 14mm, either zoom or fixed focal length). I already have the 12-40 in this focal range, and no intention to replace it, so my main consideration is size. I will only use it in good light, so it does not have to be fast, and I would likely use it most at f/5.6 or slower. Corner-to-corner sharpness is less important than good flare resistance.
