The Panasonic Leica DG Vario-Summilux 25-50mm F1.7 ASPH is Panasonic’s latest lens for the Micro Four Thirds system.
It covers a slightly unusual 50-100mm equivalent range and maintains an F1.7 maximum aperture throughout. But it makes immediate sense once set alongside Panasonic’s video-optimized 10-25mm F1.7, to which it makes a natural companion.
If the 10-25mm could be seen as a set of wide to normal primes, slotted into a single lens barrel, the 25-50mm lets you extend this set to include 50mm, 85mm and 100mm equivalents.
