Canon Speedlite 550EX. I bought this a long time ago for taking pictures at weddings, but I haven't used it much since then, so I'm selling it. I don't smoke. Although it's old, I've confirmed that it works without any problems with TTL on my EOS 7D. I've also confirmed that it can be set to a wide angle of 17mm using the wide panel operation (see photos). There are no cracks or scratches on the lens. It's clean. There are some scuffs on the exterior, but there are no cracks or problems with the head movement. The flash works, of course, and I believe it functions without any problems. The guide number is 42 at a 50mm angle and 55 at a 105mm angle. It can produce a powerful and reliable flash. Accessories include the instruction manual, case, stand, sales card, original box, and all other items. There are no missing items. ○ Other Information The number of flashes is small, and it's currently working without any problems, but please understand that this is a used item, so please make your purchase with no claims. Returns are not accepted to prevent replacementトラブル. Please understand the above points before making a purchase. #Speedlite #550EX #Strobe #Flash #FullyFunctional
