A Macro Focus Rail Slider That Fits Your Needs

A macro focus rail slider is a device that is used primarily for adjusting focus.macro focus rail slider It allows photographers to create images by focusing on one or more selected areas of a scene while moving the camera along the focus rail. Although slider cameras are a relatively recent technological innovation, they are quickly gaining in popularity. In this article we'll take a look at the many different types of sliders and how they can be used in your macro photography workflow.

The rock-steady focus slider, sometimes called a fine-tuned focus lock, has been around for years and is perhaps most associated with the Nikon macro lens.macro focus rail slider There are actually three separate motors that enable the focus to remain in place when the camera shifts. The first motor, often called the travel motor, remains in a constant position regardless of the angle of the lens. The second motor is called the knuckle, and it rotates when you make the necessary focal adjustment. Finally, the last motor, known as the toe, rotates at the same speed as the travel and knuckle motors helping to ensure a sharp, clean focus when changing from manual to automatic focus.

There are actually a number of manufacturers who designed dedicated sliders to meet the requirements of a macro photographer's workflow. Some manufacturers have produced a variety of different sizes and styles including those with a geared head rail and one or two locking knobs. Other manufacturers have streamlined their design but retain the general features of a slider. One manufacturer, though, takes it a step further by incorporating an extreme focusing ability into the frame. This is achieved by using a special camcorder style focusing screen that flips up and down along the focus rail. Sliders can also be purchased with an optical zoom feature that is beneficial when taking images of small objects.

Micro-focals are a type of slider that are mounted on a separate housing and consist of one or two lens balls and a cage made of rubber or metal. Unlike their large cousins, these sliders are equipped with a knothole design that allows for the use of an adjustable focus. These sliders, when coupled with a compatible camera, allow photographers to adjust the focus to portrait range by tilting the camera. As with macro-sliders, they are available in a variety of different sizes and designs, including those with one or two locking knobs and a lightweight design.

Another type of macro focused rail that is gaining popularity is the lightweight design. These sliders are most commonly used on smaller cameras such as the digital single lens reflex (SLR) and compact digital camera (CDA). The lightweight design allows photographers to achieve a smooth handheld operation that allows for macro focusing adjustments without having to sacrifice the extra weight. This allows photographers to choose a design that is right for them and their photography.

Many digital camera manufacturers now offer both SLR and CDA compatible models of the macro photography slider. Most manufacturers also offer the sliders in a variety of different sizes and designs. Most commonly found in five or seven-finder sets, these flexible cameras with focus rails can also be purchased in smaller sizes called micro-mounts. For truly flexible options, many professional photographers prefer to purchase a Canon macro lens mount because it allows them to easily adjust for focal length changes, manual focus adjustments, and other important macro photography functions. Whatever your photography needs, there is sure to be a macro rail system that will meet your expectations.
