The Zeiss name lives upto its standard.
The Iphone lenses deliver excellent photo quality & video quality.
No artifacts and great sharpness. No distortion and vignetting.
The lenses are well constructed in aluminum and glass. The frame to hold the lenses is sturdy.
The screw mount can be awkward for quick swaps.
The bracket mount blocks the camera’s flash and
you’re bound to lose the tiny back caps. And they’re pretty expensive.
The bottom line
Great lenses that have increased the flexibility of shooting on the Iphone. A great set of lenses for serious photographers who are ready to spend. The lenses will be a big boon for guerilla film makers, people web streaming using iphones etc.
