I have never been interested in using such items because of the impact on sharpness. But after I got test-results my opinion about the converters has changed partly. Anyway, the user needs to keep in mind other effects like increasing exposure time, DOF, bokeh, etc. Maybe it can help if a photographer is going to mountains and needs to save every gram in his backpack. So, my conclusion: instead of buying off this converter, it would be better to get cheap MD lenses with needed focus distances.
Yes, the converter works, not bad at least, but has no meaning for today. Minolta MD 24mm F2. Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle 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.
Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.
Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly.
A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens. More than just a camera lens database. Minolta SR system. Manufacturer description The Minolta S and L 2X Tele Converters are sophisticated optical accessories that double the effective focal length of the lens they are used with.

One of the best According to lens-db. Unable to follow the link You are already on the page dedicated to this lens. Cannot perform comparison Cannot compare the lens to itself. Image stabilizer A technology used for reducing or even eliminating the effects of camera shake. Original name Lens name as indicated on the lens barrel usually on the front ring.
Format Format refers to the shape and size of film or image sensor. Angle of view Angle of view describes the angular extent of a given scene that is imaged by a camera. Mount A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.
Lens construction Lens construction — a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc. Focal length The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc. Speed The largest opening or stop at which a lens can be used is referred to as the speed of the lens.
Closest focusing distance The minimum distance from the focal plane film or sensor to the subject where the lens is still able to focus. Closest working distance The distance from the front edge of the lens to the subject at the maximum magnification.
Magnification ratio Determines how large the subject will appear in the final image. Manual focus override in autofocus mode Allows to perform final focusing manually after the camera has locked the focus automatically.
Electromagnetic diaphragm control system Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting. Number of blades As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be. At maximum aperture, the opening will be circular regardless of the number of blades.
Weight Excluding case or pouch, caps and other detachable accessories lens hood, close-up adapter, tripod adapter etc. Maximum diameter x Length Excluding case or pouch, caps and other detachable accessories lens hood, close-up adapter, tripod adapter etc.
For lenses with collapsible design, the length is indicated for the working retracted state. Weather sealing A rubber material which is inserted in between each externally exposed part manual focus and zoom rings, buttons, switch panels etc. This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.
A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts. Lens mounts of competing manufacturers Canon, Nikon, Pentax, Sony etc. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.
The flange focal distance FFD is the distance from the mechanical rear end surface of the lens mount to the focal plane. Lens construction — a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.
Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements. Group — a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.
The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.
The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be.
Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow. In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both. The minimum distance from the focal plane film or sensor to the subject where the lens is still able to focus. Determines how large the subject will appear in the final image. For example, a magnification ratio of means that the image of the subject formed on the film or sensor will be the same size as the subject in real life.
For this reason, a ratio is often called "life-size". Allows to perform final focusing manually after the camera has locked the focus automatically. Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.
Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting. As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be. Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape.
However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges. Excluding case or pouch, caps and other detachable accessories lens hood, close-up adapter, tripod adapter etc.
A rubber material which is inserted in between each externally exposed part manual focus and zoom rings, buttons, switch panels etc. Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired. Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise.
Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images. A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.
The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.
Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle 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.
Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space.
