this goal is quite fine, but if we add the hood (which can not fall back on the goal) and the cap is already a little less compact, having said that it is very beautiful photo, it is substantially the same size as the 16mm pancake but it seems he has a slightly higher image quality, and then I wanted a goal "pancake" but I prefer a focal slightly more "flexible" than 16mm, and then my nex is black ... but that's really not a criterion. it is ideal for you travelers with my nex I'm very happy, but I would have preferred to see the sun visor before buying, because it is not like I thought, it looks like a large cap lens with a hole in it and the cap comes over, when we put the hood and lens cap doubling its size ... so I do not put 5 stars, but other than that it really is well.
