Hello, I bought a tripod. For taking photos of metal and plastic plates of a few mm to taking photos and videos of metal and plastic objects of about 180cm from the ground, what else do you recommend me to buy for my iPhone 6s Plus? Is it advisable to buy lens (e.g. olloclip 4IN1 photo lens, olloclip Active Lens for iPhone 6/6s and iPhone 6 Plus/6s Plus) and flash? Which product do you recommend?
