Canon G11

!±8± Canon G11

The Canon G11 is a great device for consumers looking for a camera that allows for ease of image storage and equal ease of image capture. This 10.0 megapixel camera offers image capturing properties in high resolution, and it has a 2.8 inch LCD display screen with zoom view finding features. The Canon G11 has several different zoom features too; users get a 100x complete zoom, a 5x optical zoom feature and a digital zoom of 20x. Like a number of different Canon cameras, this device is equipped with a nine point auto focusing feature ensuring image crispness and clarity.

For a camera that is simple the use, Canon has integrated an embedded, automated flash in the Canon G11. This makes the camera suitable for various environments and an additional flash can be added, but must be purchased separately. This camera is durable and has been crafted with shock proof and cold proof properties too. What's more, like other Canon models, the Canon G11 comes outfitted with an excellent Digic 4 processing unit.

For consumers that own a PictBridge compatible printer, the Canon Powershot G11 offers up direct printing features. A camera that has face detection technologies, a highly sensitive ISO setting, image stabilization, and a huge selection of scene modes, this camera proves superior over other digital cameras on offer today. The Canon Powershot G11 is equipped with a movie mode, a panorama mode, smart automated technologies, special effects, and it supports a variety of media.

The Canon G11 is compatible with Microsoft® Vista operating systems, it has a 35 mm lens, and automated, slow synchro and on- off flash functions. The Canon Powershot G11 has stabilization features that helps to prevent picture blur and improves handheld picture captures. The Canon Powershot G11 has an integrated orientation sensor, a vast focus range, a self timer, a USB interface, and PAL and NTSC video outputs. File formats supported by the Canon G11 include DPOF, RAW, MOV and JPEG. Several exposure control options, a 1/7 inch CCD imaging sensor, and a smile mode make this camera highly desirable. The Canon Powershot G11 is absent of touch screen features, it lacks a high definition movie mode, and it is not waterproof. However, the Canon Powershot G11 is superior in terms of ergonomic design; its light, easy to tote, and the menu button, and function setting access is simplistic to control.

An investment in the Canon G11 digital camera gets the consumer all that's needed to start capturing fantastic images. The Canon G11 is sold with the black camera body, the NBL7 lithium battery, the CB2LZ battery charger, the necessary neck strap, the IFC400PCU USB interface cabling, the AVCDC400 AV cable, and the Digital Camera Solution software application on CD-ROM.

SLR Camera Digital Lenses - Glass Or Plastic?

!±8± SLR Camera Digital Lenses - Glass Or Plastic?

SLR Camera Digital Lenses can be made of glass or plastics.  So why does it matter either way?  They are complex pieces of equipment and light is particularly sensitive to how it is treated.  Furthermore, camera lenses can be made of multiple elements that all work together to provide the desired zoom.  This all adds to the complexity  and therefore amplifies slight differences in optical quality etc. 

Some higher end complex lenses may have 20 or more elements.  These are most commonly made of glass, mainly due to its superior optical properties and also because if its relatively good resistance to scratching. Some other materials like Quartz glass, fluorite and various forms of plastic are also used.

Plastics are often used because they allow the manufacture of highly aspherical lens elements which are almost impossible to create using glass. Plastics in   can facilitate an improved lens manufacture process and improve the general performance quality of the camera too.  While plastic is often used on inner elements, they are only used on the outermost elements of all but the cheapest lenses as they scratch easily.

An indication of their utility is that molded plastic lenses are used in the manufacture of the cheapest throw-away disposable cameras. manufacturers of quality optics tend to use substitutes such as "optical resin".  While it is true that glass provides for higher quality performance than plastic, many modern and high performance lenses from big brand labels include some molded or hybrid aspherical elements.

So if you are deciding on which to go with, glass is pretty much an indication of higher quality relative to plastic.  Its properties simply treat light better and provide a truer picture.
