As digital imaging continues to make inroads into the world of professional photography, Nikons release of the D100 proves that far from being a flash in the pan, Digital SLRs really can make a valuable contribution. Styled around the more traditional F80, the D100 has a full-featured body, is nicely weighted and considerably lighter then you might expect given the amount of technology thats packed into it. The controls are nicely situated and navigating through the settings using the provided four-way movement pad becomes second nature very quickly. Picture preview comes courtesy of the built-in 1.8 inch LCD screen allowing a cursory check to be applied to any pictures taken. Unlike earlier Nikon products, its not possible to use the screen on the D100 as an alternate viewfinder, restricting its use in tight situations, but truth be told the results through the "traditional" viewfinder are perfectly adequate.
As you would expect from a six-megapixel camera, the image quality is superb at all levels from the highest resolution (a mighty 3008 x 2000 pixels) down to less intense 1504 x 1000 pixels. At any resolution, the output images are really very good, colour saturation is well up to par and overall the results stand up well. On the downside, perfectionists may well find theres a tiny amount less definition, but theres nothing here to raise anything approaching serious issues.
Power is provided from a supplied rechargeable battery pack which is both light and long lasting--up to a maximum of two hours depending on flash usage. To recharge from empty takes around two hours so it would be worth investing in a second pack. The D100 takes Type I and II CompactFlash as well as MicroDrive units which are invaluable for users looking to take any more than a handful of pictures in a single session--our tests showed a 256 MB CF card could handle around 40 hi-res uncompressed TIFF images, suddenly making a 1 GB Microdrive look extremely attractive.
The built-in flash unit, which pops up above the lens is powerful and efficient, proving effective in a variety of conditions. Unlike many digital cams it only ever fires off a single flash, effectively reducing red-eye without sacrificing performance.
Its difficult not to be impressed by the D100. Its a stylish and good looking camera which proves that beauty isnt just skin deep by providing results well above expectation. The inclusion of the fast charge battery pack means downtime is kept to a minimum and the software packages provided by Nikon (including NikonView 5) make it easy to manipulate your images and save them out to hard drive, CD or DVD. This is not a cheap buy, especially when you consider the base price excludes any form of lens, but for those with deep pockets the D100 is a force to be reckoned with. --Elly Russell
If you rely on a D100 for your paid job, then a second battery should be at the top of your purchase list. 
The Nikon CoolPix 2000 Is a must buy for any person who would like a good digital camera. This Camera is sleek, pretty and of course the quality of the pictures is incredible, (and I only have it on normal quality, It can go from basic to Excellent). This Camera has a great zoom function which keeps.. 
The MB-D100 is a beautifully designed adjunct to the Nikon D100 professional digital camera. But at more than £200, its not an impulse buy.
I recently took the plunge to digital mainly because I was getting sick of carrying round a big (but very good) SLR plus lenses, plus remembering to buy film, plus remembering to keep my processing slips, plus having to wait for a week after holidays to see the results.
The Coolpix 5400 will not produce satisfactory photographs in flash mode with the Wide Angle Converter lens fitted because the lens blocks the cameras photocell sensor.
