Voigtlander NOKTON 35mm F1.2 Aspherical III VM. Mainly effective for shooting still subjects. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images. Canon's Super UD, Nikon's Super ED, Pentax' Super ED, Sigma's FLD ("F" Low Dispersion), Sony' Super ED and Tamron's XLD glasses are the highest level low dispersion glasses available with extremely high light transmission. Corrects vertical camera shake during following shots in a horizontal direction. Corrects vertical and horizontal camera shake. : Elec. Voigtlander 10mm f/5.6 Heliar-Hyper Wide Aspherical Lens ... Nokton 40mm f1.4 and close up adapter in a photoshoot. The change of focal length and the manual focusing is achieved by one and the same ring. This is the simplest type of focusing used mainly in wide-angle and standard prime lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens. I can focus a 50mm F/1,4 wide open no problems, and as far as I can figure, 40mm at F/1,2 works similar depth of focus to a 50mm F/1,5. Hybrid IS dramatically enhances the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies. This article is a short review of one of my favorite Voigtlander lens – 40mm F1.2 Nokton Aspherical in Leica M mount. Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. Digital sensors are usually smaller than 35mm film, and this causes the lens to have a narrower angle of view than with 35mm film, by a constant factor for each sensor (called the crop factor). 50 mm/1:1,2 Nokton. I was importing Cosina Voigtlander 6 months before the first USA importer, THK. It has the advantage of introducing relatively little change in aberrations with respect to change in focusing distance. The distance from the front edge of the lens to the subject at the maximum magnification. Corrects horizontal camera shake during following shots in a vertical direction. It’s not a focus issue. This website calculates angles of view of lenses automatically by the following formula: 114.6 * arctan (21.622 / CF * FL). This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background. ... Voigtlander Super Wide Heliar 15mm F4.5 III E-Mount - Duration: 2… However, this lens has even shorter flange focal distance of 27.8mm. Hd. Aspherical elements (ASPH, XA, XGM) are used in wide-angle lenses for correction of distortion and in large-aperture lenses for correction of spherical aberration, astigmatism and coma, thus ensuring excellent sharpness and contrast even at fully open aperture. It is often thought that image blur caused by camera shake can be prevented by using a tripod. To avoid this, Canon, as the manufacturer most widely using fluorite in its telephoto lenses, never uses fluorite in the front and rear lens elements, and the white coating is applied to the lens barrels to reflect light and prevent the lens from overheating. The focus and aperture controls are just right! The lens features a zoom lock to keep the zoom ring fixed. Diffraction elements (DO, PF) cancel chromatic aberrations at various wavelengths. Corrects vertical and horizontal camera shake. Rounded ten-blade diaphragm contributes to a smooth quality of bokeh. It is partly the looks. In Mode 2, the movements of subjects can be captured with panning effects even when the camera is moved horizontally, vertically, or diagonally — regardless of the position of the lens. However, with constantly improving imaging sensor sensitivity, the advantage of a high-speed lens nowadays is the ability to use as a means of photographic expression the out-of-focus bokeh created by opening the aperture. The NOKTON designation is only given to high-speed lenses in the Voigtländer lineup with a maximum aperture of F1.5 or faster. Sony ILCE-7S Voigtlander NOKTON 40mm F1.2 Aspherical f/1.2 1/3200 ISO100. With glass adapter, the image quality will suffer, especially with fast lenses at large apertures (the most common adaptation and use case). The other distinctive features are fixed focal length and light-weight barrel. 2003年に世界初の35mm開放F1.2のレンズとして登場した『Voigtlander NOKTON 35mm F1.2 Aspherical VM』。その後、最短撮影距離の短縮などファインチューニングされた二代目を経て、今回ついに三代目となる『Voigtlander NOKTON 35mm F1.2 Aspherical III VM』が登場しました。 Apodization element ( APD ) is in fact a radial gradient filter, which is 44mm frame.
