The common feature of the models using fixed lens is that the zoom lenses are often very large and the prices are usually higher than with point and shoot entry-level cameras. Conversion lens can be added to some fixed lens cameras to improve the zoom and wide angle capabilities.

As fixed lens models have shared some common features with DSLR cameras, but they are not DSLRs. Therefore, sometimes they are called “entry-level” DSLR models or DSLR-style models and ranked in the class of DSLRs. Such models are very nice in cases where a photographer at the intermediate level wants to change from an entry-level camera to a DSLR camera.

Also Called: beginner DSLR or DSLR-style camera.

An external flash is located on the top of a digital SLR camera

With entry-level digital cameras, you often see a built-in flash unit and the firing of the flash is often automatic whenever there is a need for more light. With the digital SLR models, the built-in flash units are not available, so you have to use external ones.

This flash is connected to a camera via a hot shoe that is commonly found at the top of a camera. Without this hot shoe, you cannot make your camera to work with the flash. You also find batteries of an external flash separated from the camera.

You can understand the definition of the flash as both the flash of light in the firing and the actual unit which produces the light.

Also Called: Flash

HDMI

203626

HDMI, as abbreviated from High Definition Multimedia Interface, refers to an interface for transferring uncompressed digital data among devices. To make use of the HDMI, you’ll need certain types of cables as well as linking slots.

A HDMI is commonly used with high definition TVs to link to devices that produce HD signals, for example a Blu-ray playing device or a set-top box. For several digital models, especially the ones with the capability to record full HD movies, you can make use of the HDMI connector for transferring the movies to a HDTV or computer faster.

16:9 Ratio

203140

16:9 ratio refers to the measuring unit of a photo’s dimensions that can ensure a nice display of photos on a large screen, for example HDTV. 16:9 means that the image measurement has the ratio of sixteen pixels in width and nine pixels in height, so the width is 1.78 times of the height. You can see this ratio in HD movies more often than in still photo photography.

There are other typical aspect ratios available in a digital camera, including 3:2 and 4:3. For most digital models, you often work through the menu for the aspect ratio setting.

Also Called: Aspect Ratio

Flash

203709

Flash refers to an artificial source of super strong light that is used for bringing more light to photos when needed. The firing of the flash is just before you shoot the photos so that there will be more light for the lens as well as image sensor to capture a digital image. Flash can be known as either the flash of light during image capturing or the physical flash unit which produces the light.

You will often find a built-in flash unit in cameras that are aimed at entry-level photographers and the firing of the flash is commonly automatic whenever there is a need for more light. The flahs configurations can be changed through the menus of digital models and you can also fully turn of the flash. But when you use these available small flash units on entry-level models, you possibly encounter a redeye issue with your images.

For high-end digital models, you can control the flash better, both the flash firing and the amount of the light from the flash. The sizes of these flash units are often larger and they are stronger. In addition, you are able to remove the flash from high-end cameras.

A powerful flash of high quality will be very useful for making the image quality better while for some other tiny built-in flashes, the range for working well may be just several feet, for instance.

When the autofocus function is being used and the camera needs addition light from the flash, there may be at least two flashes. The first one is to bring more light for the camera to make use of the autofocus feature while the second one refers to the actual flash for shooting the photo.

The word “flash” can be also known as the flash memory, even though these two things of a digital model has no relation.

Below are the two common kinds of viewfinders found in a digital camera.

An optical viewfinder refers to an actual window that tries to match the going line of the main lens. Several advanced digital models connect the optical viewfinder with the lens. By using a set of built-in mirrors and prisms, now you can easily find the viewfinder look through the camera lens.

An electronic viewfinder, or abbreviated as EVF, refers to a small LCD which shows the photo that shall be taken. You can see the settings of the camera through the EVFs but it can be hard to see these EVFs when there is a lack of light.

Three types H, M+, or M cannot work well with several Olympus or Fujifilm digital models of the older generations.

Olympus as well as Fujifilm has used their own xD cards since 2002. The shape of xD cards is a little bit rectangular, with one slightly curved edge. The measurement of xD cards is 20 mm x 25 mm x 1.78 mm (equivalent to 0.79 x 0.98 x 0.07 in.)
