Your iPhone is already more capable than many of the regular digital cameras money can buy. Some people still prefer having access to manual buttons and controls to adjust their settings though. The RetroVa Kit for iPhone 17 can help. It has a shutter button as well as a zoom lever, control dial, and multi-functional button that lets you capture shots, switch focal length, change ISO, exposure, white balance, and switch mode. RetroVa has a modular design, so you can try all kinds of lenses, filters, and straps.
The RetroVa Kit comes with a mechanical grip and 235mm telephoto extender. It has a microSD slot in the grip for expansion. You can record ProRes and RAW files to these cards. This gadget combines with the PGYTECH app to let you control shutter speed, IOS, and white balance. You can find this project on Kickstarter.
