Photographers/videographers in Seoul, I am looking to buy two gimbals. One for my phone, and one for my dslr. I’m looking at the DJI OM6 and the DJI RS 3. First, do you use and recommend these two models? If yes, why: if not, why not? Second, where in Seoul can I go to purchase these? Somewhere that sells compact cameras, too—for recording up to 4K video. Either a big place—or a smaller place where you personally know and trust/like the owner. Thanks in advance!
