Sony Alpha DSLR-A390L and DT 18-55mm lens

The Sony Alpha DSLR-A390L + DT 18-55mm lens is a camera kit designed around a 14.2 MP CCD and is aimed at the amateur and beginner photographer. It features a BIONZ image processor to help capture shots at up to 2.5 frames per second and the body of the camera has a smooth, stylish design and is very lightweight.
For great auto-exposure it has a 40-segment metering system along with Sony’s D-Range Optimizer to balance things out in case your subject has very tricky lighting. For example, sometimes your subject is heavily backlit or the overall shot just has extreme lighting conditions. In these cases, the D-Range Optimizer will pull back the exposure on the bright parts and increase the exposure on the darker parts automatically.

Nikon Nikkor AF-S DX VR 55-200 mm f/4-5.6G Review

The Nikon Nikkor DX VR 55-200 mm f/4-5.6G is an entry-level telephoto lens designed for use with DX format digital SLR’s like the Nikon D80. This lens is designed to compliment an existing general-purpose kit lens so if you have the 18 – 55mm kit lens this one takes over where the other one stops, extending your coverage to an equivalent of 300mm. That’s a pretty respectable telephoto performance and will allow you to get really close to your subject.

Nikon Nikkor 35mm f/1.8 DX lens

The Nikon Nikkor 35mm f/1.8 DX lens has the highest cost-to-benefit ratio of any lens you can get for your DX camera. With a maximum aperture value of 1.8 this is a great lens for a shallow depth of field as well as for low light photography. It is a prime fixed-focal length lens so you will be using your body to do the zooming with this one. The AFS written on the side of the lens means it has an onboard focusing motor which is nice if the camera you have doesn’t have internal body focusing.

Nikon D3100 AF-S DX 18-55 VR lens Review

Nikon have managed to produce a truly amazing camera in the Nikon D3100 and at a price that is somehow still affordable.

It’s clear that Nikon put all their effort into making a camera that produces great images and didn’t worry too much about the specs or any wacky features that won’t add much value.

Optical Distortion explained

Optical distortion is a serious problem, low-cost or high quality lenses produce distortion. This post explains the origins of these anomalies, how to reduce their results while shooting or using computer programmes.

Aberrations are caused by the shape and the design of a lens. These aberrations lead to optical distortion which does not affect so much some subjects, for example, landscapes. Optical distortion, instead, makes obvious in buildings or in highly geometric structures such as chess boards. The degree of distortion a lens produces does not depend on lens focal length: so we have the same grid pattern from 18mm up to 300mm. However, wide-angle lenses usually originate stronger optical distortion than tele-lenses.

Canon EF-S 18-135 mm f/3.5-5.6 IS lens review

The Canon EF-S 18-135 mm f/3.5-5.6 IS lens is considered to be an economical choice but with clutched image stabilization and an amazing 7.5x zoom range which is equal to 29-216 on a 35 mm camera is everybody’s pick. The image stabilizer assures sharp shots at shutter speed up to four stops slower than without stabilization. The look of the lens is pretty eye catchy with barrel of the lens made out of texture finished plastic and silver ring besides focus control. The zoom ring can be managed easily because of the broad rubberized grip. Focus execution takes place internally because of which front filter does not rotate while zooming thus making polarizing filters easy.

The purchase of the kit is especially convenient for those who prefer to spend little and are not very practical in digital SLR photography.

The EOS 1000D had been surpassed by other manufacturer’s offerings in it’s price range and it’s features were starting to look a little weak. It was time for Canon to step their game up and they did just that. The EOS 1100D was introduced in early 2011 has all the bells and whistles to reclaim the budget DSLR crown with:
