Adding shutter buttons and lenses to an iPhone should improve the shooting experience. The Telesin Master Grip Kit produces usable photos, but it doesn't improve the experience or the output, and it is too expensive for what it offers.
AppleInsider's reviewer loves iPhone photography and notes that Apple has invested heavily in its computational photography system to deliver the best and most personal results. Accessories can sometimes enhance that experience and elevate the final image, but that isn't always the case here.
After testing the Telesin Master Grip Kit for several weeks, the reviewer struggled to find a reason to add it to their photography workflow. Unlike other iPhone lens kits tested, such as those from ShiftCam or Sandmarc, Telesin's kit is awkward to use and comes with some odd caveats. The lenses do get the job done when the right conditions are met. The resulting photos are optically better than digitally zooming beyond 100mm, but they require special hardware and an app.
The kit includes two lenses, but they are sold only as a pre-configured bundle, so buyers cannot choose just one. Either lens attaches to the Main or Telephoto camera using the grip case. The Grip includes a mode dial, zoom lever, function button, shutter button and a 3,200 mAh battery that charges the iPhone via MagSafe. The reviewer is not a fan of the grip, particularly its lanyard, which provides a false sense of security.
