.......On another topic, a mother said to do photos and videos of the children, and someone recommended Canon 24-70 F2.8L + 70-200 F2.8L. For me, seemed a snobby comment, or sadistic.
Actually this forum may not be a good place for such questions. Do not get me wrong, this is in itself a great forum with knowledgeable contributors about gear and rumors. Even for some technical stuff this is wonderful. But this is definitely not a forum where the photography part is the prominent element, the gear is more prominent element here. But that IS the characteristic of this forum. If someone here just recommended 24-70 F/2.8 and 70-200 f/2.8 to a mother for kids photography that is still fine - the recommender may have used that gear and is happy to recommend that. (For me at least) When such recommendation become sadistic and snobby is when the recommender tries to "prove" that there is no life/world/existence beyond those particular pieces of gear and anyone trying to work with lesser equipment has no idea about photography.
