Soon I will publish here in the blog my report about the first inserts of the new Sigma 100-400 L-mount lens with the Panasonic DC-S1R in the photo area and with the Panasonic DC-S1 in the video area.
The Sigma 24mm F1.4 Art wide angle lens is designed for full-frame Cameras, and when used on digital cameras with an APS-C size image sensor, it effectively becomes a 38mm.
The Sigma 24mm /1.4 lens is ideal for capturing a variety of photography subjects, including cityscapes, mountain ranges, astrophotography and weddings and is great for videography work as well.
The 24mm also excels at indoor photography in low illumination thanks to the combination of exceptional focal plane sharpness, and gorgeous bokeh rendered by nine rounded aperture blades. The lens achieves a maximum magnification of 1:5.3 with a minimum focusing distance of 9.8 inches.
The 24mm incorporates both "F" Low Dispersion (FLD) glass and Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups to minimize chromatic aberration of magnification especially in the edge of the image field. Moreover, the optimized power layout includes aspherical elements that are positioned in the rear of the lens for improved wide open performance. This helps to ensure minimal distortion through the correction of axial chromatic aberration and sagittal coma flare. The new lens element design also delivers excellent peripheral brightness. Other updates to this lens include a new full-time manual focusing mechanism that switches to manual focusing, simply by rotating the focus ring, even when AF is being used, first introduced on the 50mm Art. This allows the photographer to make fo c

Das SIGMA 70mm F2.8 DG MACRO Art-Objektiv ist darauf ausgelegt, die optische Leistung in den Vordergrund zu stellen und somit die anspruchsvollen Anforderungen an die Bildqualität zu erfüllen,
die die Art-Produktlinie definieren. Aus diesem Grund wurde auf die Innenfocussierung verzichtet. Das 70mm Objektiv liefert eine für den mittleren Telebereich beeindruckende Auflösung und
unglaubliche Klarheit, die deutlich über die Erwartungen an ein Makro-Objektiv hinausgehen. Der eisenlose Gleichstrommotor verbessert die Bildqualität weiter, während ein optimierter Algorithmus
für eine außerordentlich gleichmäßige Autofokus-Leistung eines schwereren leistungsstarken Objektivs sorgt.
Um bei jedem Aufnahmeabstand Höchstleistungen zu erzielen, verfügt das Objektiv über einen ausfahrenden, zweigruppigen Floating-Fokusmechanismus. Für optimale Ergebnisse bei allen
Aufnahmedistanzen minimiert diese Konfiguration Aberrationen. Um Farblängsfehler zu minimieren, enthält das optische System zwei FLD-Glaselemente, zwei SLD-Glaselemente und ein Element mit einer
hohen Rate anomaler Teildispersion und einem hohen Brechungsindex. Zusätzlich tragen zwei asphärische Linsenelemente dazu bei, bei kurzem Aufnahmeabstand die Auflösung zu erhöhen. Dieses optische
System ermöglicht einen gestochen scharfen Fokusbereich, der im Kontrast zu einem Bokeh-Bereich ohne Farbschlieren steht.
Das Fokus-by-Wire-System verhindert die direkte mechanische Verbindung zwischen Fokusring und Fokusantrieb. Ein entwickelter eisenloser Gleichstrommotor, gesteuert durch den neuesten Algorithmus
von SIGMA, regelt die Fokussierung leise und mit optimaler Geschwindigkeit.
Der manuelle Fokus ist auch während des Autofokus verfügbar, sodass der Fotograf durch einfaches
Drehen des Fokusrings die Schärfe manuell präzisieren kann. Darüber hinaus hilft der große Drehwinkel des Fokusrings dem Fotografen dabei, die für die Makrofotografie erforderliche äußerst
präzise Fokussierung zu erzielen.
Panasonic LUMIX S 24-105mm F4 Lens, Full-Frame L Mount, Optical Image Stabilizer and Rugged Dust/Splash/Freeze-Resistant for Panasonic LUMIX S Series Mirrorless Cameras - S-R24105 (USA)
My experience with this lens on the DC-S1R
The full-frame lens Lumix S 24-105 mm / F4 / OIS is an excellent standard zoom, which is to the credit of the Lumix DC S1R. Its sharpness performance is outstanding in the low and medium focal
length range of the 47.3 megapixel camera.
Sigma MC-21 Mount Converter to use Canon EF - EFS Lens with Panasonic S Serie L-Mount
With the SIGMA Mount Converter MC-21, owners of SIGMA interchangeable lenses with SA connector or EF connector (for Canon) can use their lenses on L-mount camera enclosures. This converter
provides more choice for L-mount cameras, which improves the extensibility of the L-mount system.
Effective use of lenses
By using the MC-21 on the compatible SIGMA interchangeable lenses with SA connector or SIGMA interchangeable lenses with EF connector (for Canon), these can be used as L-mount system lenses to
promote the effective use of existing valuable lenses.
29 interchangeable lenses are available for use on L-mount cameras
The MC-21 increases the number of sigma-manufactured interchangeable lenses that can be used with the L-mount system by 29 lenses. Thanks to compatibility with the Auto Crop function, the DC
lenses designed for THE APS-C format can also be used on a camera housing with a 35mm full-frame sensor.
Construction
With the MC-21 mount converter, SIGMA interchangeable lenses with its own SA connector and SIGMA interchangeable lenses with Canon connection can be connected to the L-mount camera system.
Fast and precise autofocus
In AF-S mode, a high-precision AF is achieved. (Not compatible with AF-C mode.)
Simple interface
The LED display and the colour of the LED display make it immediately clear whether the mounted lens is compatible or not. The LED also indicates whether a lens firmware update is
available.
Pre-implemented lens data
Due to the utilization of the data of the respective lens pre-implemented in the MC-21 by the special control program, autofocus and aperture control were optimized. With respect to lenses that
will be published in the future, the data for the operation of these lenses are stored on the MC-21 in the lens. This means that no firmware update will be required for the use of future lenses
on the MC-21. In addition, the MC-21 also supports camera correction functions such as vignetting, color cross error, and distortion.
