How to Choose an Appropriate Digital Camera with a High Quality Camera Lenses

A digital camera as the name suggest is capable of capturing, recording and storing images in a digital format. Other than storing digital images new models have Wi-Fi functionality enabled, which allows users to transfer images wirelessly on their preferred social networking sites. If you are a photographer then digital camera with good lenses is all you need, this will help you save already taken photographs on your online photo album for sharing with friends, family members anywhere and anytime around the global.

For a digital camera to be of great value to a photographer it must have a camera lens with the following attributes. Focal Length: This defines the camera’s Lens’s angle of observation. There are various types of lenses available in the market namely fixed focal span lenses which are not zoom-able and sometime referred to as primes, having a single number and the zoom lenses with two numbers indicating the extremes of the range. The other component of a digital camera is the aperture which describe amount of light gathers by the lens, normally expressed in many different ways including f4, f/4, 1:4 which offer the similar meaning. A digital camera with a smaller number indicates that the lens has a larger maximum aperture which enables it to gather more light. Having a lens with a larger aperture will allow a photographer to capture images in a lower light environment. With a digital camera having these lenses you are capable of taking photos indoor with no flash. As you go for a camera lens with larger apertures you need to note that their bigger sizes reduce the depth of the field.

The other important feature of a camera lens is the image stabilization which different manufacturers having different implementation method. Below are some references uses by various manufactures when describing Image Stabilization:
IS known as image stabilization is used by the Canon Company, OIS which refers to optical image stabilization is used by three giant companies namely Panasonic, Samsung and Fuji film, VR known as Vibration Reduction is deployed by Nikon, OS which stand for optical stabilization and not operating system is associated by Sigma Company. The Optical Steady Shot (OSS) is used by the Sony Company while Tamron uses Vibration Control (VC) to describe the image stabilization. The other two features to be considered when choosing a camera lenses are the format and the lens mount. The format is the sensor size designed for a lens to use while the mount is used to determine whether your lens will physically fit your digital camera.

Questions to ask yourself before buying Digital Camera and Camera Lenses

Does it have the ability to automatically and smartly select aperture speed based on the shooting surroundings, how much does it bring the subject into focus, how does the camera react in a low and high light situation.

The joy of weather stations

Nowadays, with Wi-Fi-enabled devices there to give us the weather forecast at the touch of a button, many would find it increasingly difficult to remember some of the alternatives once in widespread usage. Whilst some of the more rudimentary devices have since been consigned to the annuls of history, many weather stations are still available, forecasting conditions in a much more in-depth and localised fashion than basic apps ever could.

In celebration of these devices, below are a number of variations, many of which are still made today, which show a little more information about the weather than a colourful image of the sun peeping from behind a cloud.

The origins

Barometers and thermometers are most certainly not new inventions, but instead have been around for hundreds of years. The first widely-used devices, in fact, were manufactured in the 17th century, when Galileo and his contemporaries began laying the foundations of what would end up influencing modern-day weather forecasting.

Despite giving his name to an early thermometer, however, Galileo didn’t invent the device; it was instead a protégé of his. At around the same time (the mid-1600s), a simple syphon and vacuum device began exciting mathematicians and physicists, who would go on to create the earliest barometers.


These days, barometers aren’t the huge-scale devices of old that needed a 20-metre hill to work. Instead, they can be fitted into the smallest of spaces, including smartphones which use the devices for quicker and more accurate GPS placement.

On domestic weather stations, these barometers are placed onto the outdoor sensors, which can then relate information back to the individual via their user-friendly interface, which gives an accurate, up-to-the-second report on weather conditions.

Analogue barometers, on the other hand, offer similarly exact readings but do so directly, instead of feeding the information through a digital programme. Often set up to look similar to a wall-clock, these barometers have a hand which indicates the level of pressure, which illustrates what the weather is set to do. The higher the reading, the better the weather.

Rain gauges

Rain gauges are devices for those who need to be aware of minuscule changes in rainfall which work, quite simple, by catching precipitation then relaying the in-depth measurements back to a hub device. Some can also be fitted with user-set alarms so that if levels reach dangerous thresholds then they can alert the individual straight away.

These not only offer rainfall volumes, however, but also indicate outdoor temperature, giving the user a much clearer idea of the outside conditions. They can prove invaluable to farmers or anyone growing vegetation, as rainfall volumes can often mean the difference between a bumper crop and a spoiled one.


Similar to barometers (and often featuring jointly on the same device) are hygrometers, which are used to measure moisture content in the air. Utilised indoors, hygrometers can be vital to warning their owners of high levels of humidity which could prove vital in such places as museums or galleries where it could be damaging for the exhibits.

So whilst smartphones are now many people’s first port of call when it comes to checking the weather, there is still a whole host of other devices to not only offer a more old-fashioned way around it, but also a more in-depth one too.
