There is no shortage of digital cameras these days.
The new generation of interchangeable lens compacts all offer a degree of compatibility with the respective manufacturer's SLR mount via lens adapters, but in general performance is compromised to some extent - in particular autofocus is often slow and hesitant.
Prime Zoom lenses have become almost ubiquitous over the past few years, and at first sight buying a lens which is restricted to a single angle of view might seem pointless. But prime lenses still have some very real advantages; compared to zooms they tend to be smaller and lighter, have faster maximum apertures, and give sharper images.
These factors make them extremely useful for specific purposes, for example low light shooting where a large maximum aperture is advantageous. Fixed focal length 'prime' lenses are often much smaller and lighter than zooms covering the same angle of view. This is Pentax's 15mm F4 lens alongside a typical wideangle zoom, the Tokina mm F4 - the size advantage is obvious.
Some popular lens types Standard Zoom A standard zoom is a general-purpose lens that covers a range of focal lengths from wideangle to moderate telephoto. The most obvious example is the kit lens that comes with the camera generally an mm F3.
Most manufacturers offer general-purpose upgrades to their kit lenses with expanded zoom ranges suitable for a wide range of subjects, such as this Sony mm.
Telephoto zooms such as this Nikon mm allow you to zoom in on your subject. Superzoom Superzooms are all-in-one lenses which cover a full range of focal lengths from a moderate wideangle to long telephoto.
They combine in one package the range of the kit zoom that came with the camera, plus that of a telephoto zoom, and therefore make perfect general purpose travel lenses. The technical image quality is often not quite as good as two separate lenses, but for many users this is more than made up for by the convenience.
Superzoom lenses such as the Tamron mm F3. It's therefore a popular choice for landscapes, architecture, and interior shots. Wide zooms such as the Sigma mm F Some zoom lenses use 'macro' in their name to indicate closer-than-usual focusing ability, but true macro lenses tend to have fixed focal lengths.
In general, the longer the focal length, the further away you can be from your subject. Nikon calls these lenses 'Micro' instead. Macro lenses like the Olympus 50mm F2 allow you to shoot closeups in fine detail. Once an endangered species, this class of lens has seen a resurgence in recent years, and undoubtedly the most popular is the 50mm F1.
On a camera with an APS-C sensor this makes for a short telephoto perspective, ideal for snapping pictures of friends and family using natural light. Fast prime lenses such as this Canon 50mm F1.
These have enjoyed a resurgence recently as a natural companion for Interchangeable Lens Compact cameras, but are also available for SLRs most notably from Pentax and more recently Canon.
Three slimline 'pancake' lenses, from Olympus, Samsung and Pentax. Other lens features There are a few other aspects of build and operation which you may wish to consider when buying a lens.
Autofocus The autofocus system used by a lens can have a large impact on its focusing performance, particularly in terms of noise and speed.
The focus motor can be positioned either in the camera body or in the lens, and in-lens focus motors come in a variety of types with different characteristics.
Here's an overview of the most important types: Screw drive lenses don't have an internal motor, and instead are driven from the camera body via a mechanical coupling, which tends to be fast but comparatively noisy.
Entry-level Nikon bodies don't have built-in motors, and so can't autofocus with this type of lens. Micromotor drives use conventional DC motors to drive the focus group via a gear train. These tend to be found in cheaper lenses from the camera manufacturers and in many lenses from third party manufacturers particularly Tamron and Tokina.
AF performance is highly variable - at worst slow and noisy, at best reasonably fast and quiet. They come in two main flavors; the cheaper micro-type has similar characteristics to micromotors, while the more expensive ring-type has a number of advantages.The focus motor can be positioned either in the camera body or in the lens, and in-lens focus motors come in a variety of types with different characteristics.
Here's an overview of the most important types. Before choosing a camera many people will ask, what is the best camera to buy?, or what camera should I buy? While those are logical questions to ask, it is more important to first know what types of digital cameras are on the market.

The Leaf shutter or more precisely the in-lens shutter is a shutter contained within the lens structure, often close to the diaphragm consisting of a number of metal leaves which are maintained under spring tension and which are opened and then closed when the shutter is released.|
