She safari sale | Quite compact for what it is. You are absolutely right about the maximum aperture. Regardless I love this lens. I can very highly recommend this lens for anyone who is comfortable with manual focusing and needs a wide to normal high-quality zoom. It's great to see you back on the forum! |

Laowa has just announced a new 20mm shift lens, and we were able to put it through its paces in downtown Calgary. What's the best camera for shooting landscapes? High resolution, weather-sealed bodies and wide dynamic range are all important.
In this buying guide we've rounded-up several great cameras for shooting landscapes, and recommended the best. If you're looking for the perfect drone for yourself, or to gift someone special, we've gone through all of the options and selected our favorites. These capable cameras should be solid and well-built, have both speed and focus for capturing fast action and offer professional-level image quality. Although a lot of people only upload images to Instagram from their smartphones, the app is much more than just a mobile photography platform.

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. 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.
Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use. The change of focal length is achieved by turning the zoom ring and the manual focusing - by turning the separate focusing ring.
The change of focal length and the manual focusing is achieved by one and the same ring. The change of focal length happens when the photographer moves the ring towards the mount or backwards and the rotation of the ring leads to change of focus. The lens features a zoom lock to keep the zoom ring fixed. This function is convenient for carrying a camera with the lens on a strap because it prevents the lens from extending.
The lens features electronically driven zoom mechanism. It provides smoother, more natural zoom movements than you could accomplish by hand. The Holy Trinity of lenses refers to a three-lens set that covers a focal length range from the ultra-wide focal length of mm all the way long to the telephoto focal length of mm. The set typically consists of a mm ultra-wide angle zoom lens, a mm standard zoom lens and a mm telephoto zoom lens and usually represents the best constant-aperture zoom lenses in a manufacturer's lineup.
The set is designed to cover almost every genre of photography, be it landscapes, architecture, portraits, weddings, sports, travel or even wildlife with teleconverter.
