Pros

Trackpad – this is definitely a most welcome upgrade. RIM outdid themselves on this part – I thought the trackball was good, this trackpad is great! The older Bold’s trackball was great, as long as you kept dirt and dust out of it. Which turned out to be somewhat difficult, since there was a depression surrounding the trackball, and so if too much dust or dirt got in, the ball needed to be replaced. Also, if you used it too much, the ball would lose its grip, and become less responsive, also – once again – needing to be replaced. Both those problems are now gone with this new trackpad. For former trackball users, it may take a little use to get to know it, but once you do, trust me – you’ll never go back.

Speaker – the speakers on the Bold are nothing less than stunning. My friend has an IPhone, and my speakers for playing music and speakerphone blow his out of this century. Not only can they get very loud, but they also are quite clear and crisp, for the volume you can put them to.

OS – the new BlackBerry 5 OS, which comes preloaded on the phone, is a major improvement over the 4.6 version in most other phones. It’s snappier, and quite more responsive.

Camera – RIM upgraded the camera from a 2 MP in the older Bold to a 3.2 MP in the Bold 9700. The pictures that the phone takes are quite good, even in poor light conditions. Of course, if you try to take pictures in the club with it – prepare to be somewhat disappointed. Ha. But for regular, everyday camera uses, that “quick shot”, the Bold 9700 actually takes decent pictures. Nice for when you forget to bring that digital camera with you.

Cons:

Battery – battery life is still somewhat bad, although it definitely is an improvement over the older Bold. I normally use Pandora – an App that plays Internet Radio, trust me, this should be one of the first apps you download, it’s free – the other is Google Maps, also free – anyway, back to the review, so I normally use Pandora, and I can get about 6 hours out of the battery, with small breaks in-between receiving phone calls. So, in normal use, you could probably get about a day out of the battery, which isn’t terrible, but also is somewhat worse than comparable phones out there.

Hardware – this is probably my biggest negative I had. Normally, when they say upgrade, you would think they would put better hardware in the thing, right?? Well, think again. With the exception of the upgraded camera and trackpad, there is NO difference in hardware between this and the older Bold.

Product Description

Incorporating Canon’s Optical Image Stabilizer technology, this Canon 55-250mm telephoto zoom lens captures long distance, low-light shots far better than many comparable lenses, helping you photograph the far-off action of athletes or zoom in for an intimate portrait with a blurred background. The high-zoom-ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses). More significantly, the image stabilizer effect creates an equivalent shutter speed of roughly four stops faster than the same size lens without an image stabilizer. In other words, if the slowest shutter speed you can hold a 250mm lens steadily is normally 1/250th of a second, this Canon lens will let you hand-hold shutter speeds as slow as 1/15th of a second.

Used Camera For Sale

Every month, a new series of cameras enters the market, and the uninformed or undecided buyer has to make a tough decision when choosing among the wide range of morels. With the smart buying choices that we will point out in this article, you will hopefully pick one for its real features instead of the bells and whistles that the sales people are boasting. Because of these reasons, there are a lot of used cameras for sale. There are many considerations before buy used cameras for sale.

Number of megapixels

Most stores, both online and brick-and-mortar, concentrate on promoting megapixels – the more, the better. This is only a marketing technique and is not always true.

The image produced by a digital camera is comprised of a series of spots called pixels. The more pixels make up that photo, the more details it can show; in other words, the more megapixels a camera has, the more you can zoom into the image, or print in a big enough size, before it becomes fuzzy and unclear.

Total zoom

Most, if not all nowadays’ consumer cameras come with zoom feature. This functionality can be particularly useful when taking a shot of something that is too far away and you can’t get close to the subject, or you want to frame a portrait without shooting much of the distracting background.

Optical zoom is the “real” magnifying feature, the camera magnifies the image through an assembly of lenses before the picture gets to the image sensor, while the digital zoom enlarges the photo already stored in the camera. Make sure you understood the camera’s technical specifications clearly

Last day , I have found new used camera for sale in AMAZON, here I review it for you.
