Panasonic Leica DG 10-25mm f/1.7 lens MFT
- announced Sept 2018 - world 1st f/1.7 zoom lens!
- Micro Four Thirds system mount
- “Since image quality of each focal length is [as] strictly controlled as prime lenses, this lens can be seen as equivalent to five prime lenses: 20mm, 24mm, 28mm, 35mm, and 50mm,”
- a “Holy Grail” lens for Panasonic videographers although it is expensive and somewhat heavy
- much heavier, larger and much more expensive than the Panasonic Leica DG 8-18mm f/2.8-4.0 ASPH lens but you get 2-2.5 stops more light and shallower depth of field (DOF), longer focal length, plus the MF clutch and clickless aperture ring.
- covers 20-50mm in FF terms - this is a unique and very useful range which is not covered by any full frame lens as most systems have 16-35mm or 24-70mm lenses
- click-less aperture ring
- 1st Panasonic lens to have a MF clutch
- extends in zooming but not by much
- close focus 0.28m
- 77mm filter
- 128mm long
- minimal CA, coma or distortion, very sharp wide open across the range and into the edges
- sharper corners wide open than the Panasonic 25mm f/1.4 even when the 25mm is stopped down to f/2.8
- significant field curvature can make corners out of focus at 10mm and 25mm - the Panasonic Leica DG 8-18mm f/2.8-4.0 ASPH lens is much better in the corners at 10mm but not as good at 18mm, while the Panasonic Leica DG Summilux 25mm f/1.4 ASPH lenses has similar field curvature and once corrected, the corners are not quite as sharp wide open and has more CA than the 10-25mm at 25mm.
