Canon EOS 7D

While it has automatic shooting modes like most modern digital SLRs (or more commonly referred to as dSLR), the EOS 7D really shines with manual controls. The reason is that Canon Inc actually designed the camera around the specific needs of professional photographers. As such, they have built into the camera very exciting features and functions that can best be achieved through creative manual controls.

Minus points for the Canon EOS 7D

• It does not have setting for landscape, portrait, sports, etc.
• It lacks a full size sensor even though the images and video are outstanding. Unless you require very large prints very often, you may not want to spend more for this feature as the current sensor is more than sufficient for most people.
• There is a tendency for the Canon EOS 7D to overheat in warmer areas for example at warmer climates or in rooms where there incandescent lights. Even it does not always happen; the camera may shut down for 5 to 10 minutes to cool down.
• Limited video shooting. Unlike your video camera, the 7D provides you about 15 minutes of shooting mode. It will automatically shut down when you pass this time limit. This is basically a camera with a video mode!
• Its quality may not be that brilliant at very high ISO. As such you may want to look for other models like the 5D MkII instead.
• If you want simplicity, this camera may also not be for you. As it is designed based on feedbacks from professional and semi-professional photographers, Canon has put in a lot of flexibility to customize the options, buttons, settings etc It would be a waste of your money for you to use only the automatic mode.

Plus points for the Canon EOS 7D

• The Canon EOS 7D is very solidly built and fits comfortably into your hands.
• It is water proof. The weather seal of my 7D was very well designed as I was caught in heavy rain many times without any problems.
• Almost all the buttons can be reconfigured. This is especially helpful if you have been using another camera for some time and is used to the buttons of that camera. It is also useful if you have other cameras and you want to standardize the buttons as much as possible across your cameras.
• It has an excellent AF system that you can customize to suit your needs.
• The EOS 7D is self-cleaning. Every time you turn it on or off, it will vibrate quickly to remove dust from the camera and lens. You can switch this function on or off.
• It supports both Compact Flash or Microdrive card to provide you the storage for plenty of those beautiful shots.
• Framing the shot is easy with the advanced view finder.
• It has a great battery life.
• You get more focused action shots – courtesy of the 19 points AF point focusing system.

Tablet PC

For those in the know, there are two different touch screens available, either a resistive or a capacitive touch screen. iPad uses a capacitive touch screen whereas many other brands use the resistive touch screen. This difference is quite important. With the capacitive touch screen, you can only use fingers for essential on-screen navigation. It also allows features such as multi-touch support, great visibility in sunlight, and a high sensitivity to finger touch, making the screen fast and efficient. Resistive touch screens are sensitive to any touch, because they rely on pressure to register input. This makes it useful for stylus and navigating on your tablet, and is easy to use with gloves or pens, but at the same time it lacks multi-touch functioning. It is worth noting that the resistive touch screen is ideal for people wanting to use a handwriting recognition system.

When it comes to choosing a screen size, it largely depends on the resolution that you are looking for. For those largely wanting media files, video and TV, then resolution is the most important aspect. For others more interested in notebook, e-mail and word processing, then a larger screen and lower resolution is more suitable. Android can support an incredible 1920×1080 pixel resolution display but most current Android tablets are 1024 x 600 and under, as opposed to the iPad 1024×768 pixel resolution. Generally, the larger the screen the heavier the tablet, so for those traveling, a smaller screen size such as 7 inches is definitely better, but for those who want to use the tablet for entertainment purposes a 10 inch screen might be preferable.

The two main operating systems, storming the market are the Android and the IOS. There are other operating systems such as the RIM, but they tend to have fewer app options available at the present time. Androids’ app store currently has over 200,000 apps, whereas IOS (Apple) takes the lead with 300,000 apps. The main differences between the operating systems are that because IOS is licensed exclusively to Apple, applications such as Adobe Flash are not supported by the iPad. This is where Android comes in and takes the lead. With over 79 software/hardware companies assigned to their Open Handset Alliance, the sky’s the limit with where and what the apps might be available. Of course, this gives the Android significantly better usability, especially for multi-tasking professionals, and for gamers, who have the ability to play flash games. The Android operating system is used by more than 95% of all current tablets.
