ePhotozine (Click here) posted the full Leica 15mm f/1.7 lens review and writes:
The Leica name is like a seal of quality for Panasonic’s Micro Four thirds lenses, and this lens lives up to the reputation in many ways. One surprising way that it doesn’t is with the price. Yes, it may be more expensive than the closest equivalent lenses, but it’s not the kind of price that would have your bank manager asking questions.
The lens gets “reocmmended” with 4/5 stars.
