Gone are the days of f / 2.8 zoom as a reference: now we have zoom masterpieces that shift the brightness to the value of f / 1.7. This is the case with the LEICA DG VARIO-SUMMILUX 25-50mm F1.7 ASPH that with its companion LEICA DG VARIO-SUMMILUX 10-25mm / F1.7 ASPH can offer a new shooting experience.
It is a lens intended for Panasonic GH cameras where the conversion factor is 2X; the LEICA DG VARIO-SUMMILUX 25-50mm F1.7 ASPH lens therefore is equivalent to a 50-100mm in the 35 format. But above all it is the confirmation of what Panasonic announced at the time of the presentation of the S series, that is to say that they would not have abandoned in any way the development in the Micro Four Thirds.
LEICA DG VARIO-SUMMILUX 25-50 is ideal paired with the 10-25mm
The salient features of this lens acquire greater value when used in tandem with the 10-25mm. Panasonic ensures that there is no difference in rendering at 25mm, ensuring a continuity of performance from 10mm to 50mm. Inside we find 16 elements in 11 groups, including an aspherical lens and between lenses with very low dispersion to reduce aberrations.
Similar to his brother in many respects, such as the filter step, it same center of gravity or same positioning of the rings. Despite the differences in body length, having these aspects in common with the 10-25mm allows you not to have to make changes to the settings of instruments such as gimbal or follow focus. But we should also underline the excellent work done by the engineers who minimized focus breathing on the LEICA DG VARIO SUMMILUX 25-50mm. This is a very important aspect in the video field, which allows you not to change the framing during focusing operations.
The optic is obviously weather resistant and can be used at temperatures as low as -10 ° C.
The new Leica DG VARIO-SUMMILUX 25-50mm available from October at the retail price of € 1999.99.
