Μου είχε κάνει εντύπωση που στα specs έλεγαν οτι ο Sigma 500mm/5.6 δεν είναι συμβατός με τους TC , προφανώς εννοούσαν για το Εmount όπου δεν υπάρχουν.
Στο L mount o Nickols είπε οτι δουλεύουν κανονικά οι πολλ/στες της εταιρίας και θέλω να ελπίζω οτι θα είναι συμβατός και με τους αντίστοιχους της LUMIX . Έχω κρατησει τον Panasonic 1.4Χ γιαυτο ακριβώς τον λόγο να τον ταιαριαξω με ένα ελαφρύ τηλεφακό στο Lmount .
Ο 500mm/5.6 φακός δείχνει εξαιρετικος και είναι σχετικά ελαφρύς 1350γρ. οποτε πληρει τις προδιαγραφές
Η τιμή του όμως είναι τιμή FF και πολύ δυσκολα να τον πλησιάσω . Ίσως στο μέλλον αν πέσουν οι τιμές ή τον βρω μτχ.

It was designed for mirrorless cameras, characterized by a combination of exceptional image quality with an extremely compact and light housing. By using multiple specialized low dispersion glass lenses, SIGMA has managed to significantly reduce the lens structure without the use of diffractive optical elements. At the same time, the lens achieved high resolution, which meets the expectations of a fixed focal length 500 mm lens. The lens body, composed primarily of precision polymer parts, features excellent build quality and weather resistance, including a dust- and splash-proof design**. SIGMA 500mm F5.6 DG DN OS | Sports offers a completely new photography experience for wildlife, aviation, sports and other high-speed action photographers.
A handy 500mm lens with unrivaled optical parameters
Sigma 500 mm f/5.6 Sony E Thanks to the latest engineering techniques, it was possible to effectively minimize the size of the lens and maintain a high level of image sharpness and beautiful visuals.
The front of the lens uses complex lenses made of special low-dispersion glasses, which ensures both high aberration correction ability and a short overall length. SIGMA’s only production base in Aizu, Japan, guarantees high precision in the assembly and processing of each lens. The lens perfectly corrects all aberrations, especially axial chromatic aberration, which the camera body cannot correct, ensuring stable, high resolution from the center to the edges of the frame
Great work against light – Sigma 500 mm f/5.6 Sony E
SIGMA 500mm F5.6 DG DN OS | Sports uses refractive lenses in its optical system to prevent glare and ghosting that are characteristic of diffractive optical elements. Thanks to this, we can obtain sharp and contrasting images even when working against the light.
Fast AF with HLA linear drives
The lens uses an original HLA linear drive (High-response Linear Actuator), which is characterized by high speed and accuracy, as well as very quiet operation. Combined with the camera’s AF system, we achieve very effective tracking of moving objects, which is particularly important, e.g. sports, nature or aerial photography – Sigma 500 mm f/5.6 Sony E
Extremely efficient OS2 image stabilization system
The latest OS2 optical stabilization algorithm ensures exceptional vibration reduction efficiency of up to 5 EV (based on CIPA guidelines). The lens has 2 OS operating modes:
Convenience and the highest quality of workmanship – Sigma 500 mm f/5.6 Sony E
The body of the Sigma 500 mm f/5.6 Sony E has been designed to be small and light, making the lens extremely easy to use when shooting handheld. Thanks to the optimized optical construction and the use of a body made of a combination of TSC (Thermally Stable Composite) and magnesium alloys, the lens is only 23.5 cm long and weighs only 1370 grams.
A wealth of functions supporting demanding photographers
The manual aperture ring allows you to conveniently control exposure. The ring rotates smoothly or with a characteristic “click”, and if necessary, we can lock it in the Auto position. The lens also features a Focus Limiter switch that allows users to limit the range of the AF system, allowing for quick and precise focusing. Additionally, we have three AFL buttons that can be assigned a number of functions via the menu of selected cameras. The AFL buttons are easy to use regardless of camera orientation and provide quick and easy access to important settings. In the L-mount version, the SIGMA USB DOCK UD-11 can be used to set operating system behavior or the focus limit range for the custom mode switch*.
Reinforced housing body – Sigma 500 mm f/5.6 Sony E
The lens has increased resistance to weather conditions, in line with the specifications of the SIGMA Sports line**. The mount bayonet, manual focus ring, switches and external connectors are equipped with seals to prevent dust and dirt from entering the lens. Moreover, the front element of the lens is coated with a waterproof and oil-resistant coating, which makes maintenance easier if water droplets or dust enter the lens.
