Έχουν κιαλλες διαφορες κυρίως κατασκευαστικες :

For one, it uses an all-metal housing which may make it more resistant to the elements — weather resistance is a repeated theme of importance to Leica. Additionally, Leica removed all buttons and switches from the exterior of the lens — even the manual focus/autofocus switch — which means that can only be adjusted from the camera itself, but also may make for fewer weak points where moisture or dust could sneak in and damage the internals. Additionally, Leica’s lens hood is made of metal.

There are some other minor differences, too. While the Leica weighs more (no doubt due to the additional metal parts), Sigma states an 84.1 to 34.3-degree field of view while Leica states an 82.3 to 35.3-degree field of view. Leica also has published a 7.1-inch minimum focusing distance while Sigma states a 7.09-inch minimum focusing distance — minor, but different.

Εκτος από αυτά είναι σίγουρο οτι το firmware για την DFD εστίαση το έχουν μόνο οι φακοί της Panasonic το οποίο έχει νόημα μόνο και εφόσον κανείς χρησιμοποιεί L σωμα της Πανυ.

Τωρα αν ολα αυτά δικαιολογούν την κατά πολύ υψηλότερη τιμή είναι αλλου παπά ευαγγέλιο

εδω εχει ενα συγκριτικο μεταξυ των 24-70 leica & art με τον leica 24-90 και αποτι ειδα η σειρα απο τον καλυτερο στον χειροτερο και παντα μιλαμε για image quality
ειναι οπως θα ηταν αναμενομενο leica 24-90>leica 24-70> sigma 24-70 .
Με μονη παραφωνια οτι στο 24 ηταν ο νεος leica καλυτερος απ'ολους .
Η διαφορα των 24-70 ειναι ουσιαστικα στην καλυτερη δυνατοτητα του νεου leica εναντι του art στα ακρα του καδρου .
Οποτε δεν τον δινω τον canon 27-70 2.8 mk2 : ) εκτος αν πιασω joker και παρω τον παλιο leica ....

Panasonic has announced its Lumix S 24mm F1.8 lens for L-mount. This lightweight lens features 12 elements in 11 groups, including three aspherical lenses. Three extra-low dispersion and one ultra extra-low dispersion elements help suppress chromatic aberrations. It uses a linear motor to drive the focus group for swift and silent autofocus, and Panasonic says that the lens has been designed to minimize focus breathing. The minimum focus distance of the 24mm F1.8 is 24cm (9.5") and the maximum magnification is 0.15x.


The 24mm F1.8 is designed to fit alongside the 50mm F1.8, 85mm F1.8 and upcoming 35mm F1.8. Those lens are the same size, roughly the same weight, and have controls in the same locations, so gimbals, drones and follow-focus systems will need little-to-no adjustment when swapping lenses. The lens is sealed against dust and moisture.


The Lumix S 24mm F1.8 will be available in mid-October for $899.

Panasonic Announces Compact, Lightweight LUMIX S 35mm F1.8 (S-S35) for the LUMIX S Series

The New 35mm Wide-Angle Fixed Focal Length Lens Features F1.8 Large Aperture

Newark, NJ (October 9, 2021) –
Panasonic is pleased to introduce a new large-aperture wide fixed focal length lens, the LUMIX S 35mm F1.8 (S-S35), as the fourth addition to the series of four F1.8 large-aperture lenses based on the L-Mount system standard. A total of four F1.8 fixed focal length lenses from the LUMIX S Series including 85mm(S-S85), 50mm(S-S50), 24mm(S-S24) and the new 35mm(S-S35) lens feature a common size and position of control parts to provide practical advantages in use. The center of gravity of these lenses is comparable, allowing easy and quick exchanging of lenses with minimum balance adjustment when the camera is on a gimbal. Consistent diameter also enables the use of common filters, and users will benefit from its descriptive performance.

The LUMIX S 35mm F1.8 is comprised of eleven lens elements in nine groups including three aspherical lenses and three ED (Extra-Low Dispersion) lenses. The use of three aspherical lenses realizes both high descriptive performance and beautiful bokeh, which are common advantages to the series of all F1.8 lenses. The ED lenses also effectively suppress chromatic aberration. The LUMIX S 35mm F1.8is suitable for versatile situations including landscapes, snapshots and portraits. Minimum focusing distance of 0.24m also produces high-quality close-ups.

The LUMIX S 35mm F1.8 is capable of smooth, silent operation, working with the camera’s high-speed, high-precision contrast AF system with the sensor drive at max.240 fps. For the non-linear setting, focus is shifted with a variable amount according to the rotation speed of the focus ring, while focus is shifted with a designated amount according to the rotational quantum of the focus ring for the linear setting. Sensitivity, or the amount of focus shift per rotational quantum, can be selected from 90 to 360 degrees by 30 degrees to enable intended focus operation. The LUMIX S 35mm F1.8 also excels in video recording performance with a mechanism that suppresses focus breathing, which was a fatal problem of all interchangeable lenses designed for still image photography. Together with a micro-step aperture control for smooth exposure change, the lens achieves professional quality video recording.

With its approximately 295g compact size and light weight, the LUMIX S 35mm F1.8 features stunning mobility to fit the S5, LUMIX’s smallest full-frame model. The rugged dust/splash-resistant*1 design withstands use under harsh conditions even at 10 degrees below zero for high mobility. The filter diameter is 67 mm, with a 9-blade circular aperture diaphragm.

To further strengthen the S-Series lens system, development is underway for a new 18 mm ultra wide angle fixed focal length lens with F1.8 large aperture. Alongside the development of new lenses, firmware update programs*2 are also available for the conventional S-R70200, S-E70200, S-R70300 and S-R24105 lenses to improve the stability of Image Stabilizer during video recording. In addition, image stabilization performance of Dual I.S. 2 has been increased from 6.5 stops to 7.5 stops*3 for photoshoot when the S-R24105 is mounted on the LUMIX S1H, S1R or S1.

Panasonic and L-Mount system alliance is committed to further expansion of L-Mount lens lineup, as well as the enhancement of performance, to fulfill the needs and maximize satisfaction of customers.

*1 Dust and Splash Resistant does not guarantee that damage will not occur if this lens is subjected to direct contact with dust and water.
*2 Firmware update programs for S-R70200(Ver.1.2), S-E70200(Ver.1.1), S-R70300(Ver.1.1) and S-R24105(Ver.1.2) are available at https://av.jpn.support.panasonic.com/support/global/cs/dsc/download/index4.html
*3 Based on the CIPA standard [Yaw/Pitch direction: focusing distance f=105mm.] Performance is guaranteed when the S-R24105 is mounted on the LUMIX S1H, S1R or S1, as of November 9, 2021.

The LUMIX S 35mm F1.8 (S-S35) will be available at the end of November for $699.99
