Tired of trying to keep updated with the highest mega pixel resolution digital camera? Well even if one has tried to do that, most certainly he will soon find out that his few months old digital camera is outdated in terms of mega pixel resolution. It's an ever changing kind of product that has become very hard to keep updated, unless one is willing to spend more money by making purchases every six to twelve months.

If the main intention of purchasing a photo camera is enlarging the image, then mega pixel resolution indeed will become the main factor. In this case one might consider a different option, which will keep his product updated for years to come. I'm talking about a used 4x5" film photo camera, together with a high resolution flat bed film scanner. All of this for less than one thousand US dollars. With all of this, one will get over 100 mega pixels in fine detailed film resolution and fine scanned digital images that can be enlarged up to 30x40" in size with professional quality. These 4x5" film cameras have done a remarkable job in general personal and commercial photography such as wedding, portraiture, product, documentary, advertising and landscape for nearly a hundred years.

Where to find 4x5" used film cameras? Since some of these cameras were mostly used in the past, until the 1960's, it should be no problem in finding them in American auction web sites. Anyway, a good used 4x5" camera with lens can be found for less than four hundred US dollars.

As for the flat bed film scanner, one can find brand new ones for less than five hundred US dollars. Just make sure the scanner is able to scan films.

Whenever purchasing a 4x5" film camera, one should look for the following features: folds into a compact box, flexible bellows, lenses that can be easily interchanged, accepts sheet film, ground glass focusing screen, easily handheld and optical viewfinder accessory.

As for the lenses, there are four main categories: 1 - general purposes; 2 - wide field (mostly used for close up work and landscape); 3 - extreme wide angles lenses; 4 - special effects lenses (telephoto). However, one might use a general purpose 127 or 152mm lens for most of his photograph sessions. In cases where it requires special lenses, such as architecture or macro photography, one will still find lots of them available in auction sites. Used lenses for 4x5" cameras made after World War II have excellent performances comparable to today's modern lenses.

Whenever making a purchase of a 4x5" camera make sure that: 1 - the bellows have no light leaks, 2 - the lens shutter works accurate at all speeds; 4 - the lens elements have no fungus and scratches of any kind; 4 - the focus is working properly between the ground glass and the film.

The option of using a 4x5" film camera, together with a flat bed film scanner, for enlarging images with professional quality is viable and accessible. Cheaper than top digital cameras, the 4x5" film camera offers better image quality and will always be updated in the future, maintaining its original value.

For those who wishes the very most detailed image enlargement, one can always use the 8x10" film camera. Four times the physical film size of the 4x5", this option offers so much film resolution that it is considered by many as the ultimate step for photo image enlargement.

Sometimes analog products deliver better results that its digital counter parts. If you are doing the job of enlarging photo images, you should give it a try with a 4x5" camera. You might just surprise yourself.

Nikon is in a very competitive market, so that has to do other producers a direct impact on the direction of Nikon products. Twenty years ago, followed, established in possession of the Nikon professional 35mm photography, and then came to AF camera. Canon has traditionally been the company No. 2. However, with autofocus, Canon procedures performed, since both companies updated their product lines with new technologies. Then came digital photography, Canon has taken the opportunity andthrough innovation and aggressive marketing as Nikon, have taken the number one. Have become the camera of choice for most professionals, the early 21st Century. Nikon responds hard at the end of 2007 with the launch of the D3 and D300 - which is precisely the Olympic Games in Beijing, about half of the witnesses have been shooting professional Nikon, Canon and the rest. Four years ago in Athens, Nikon were few and far between.

Now is the second half of 2008, and Canon is firing back overArch Nikon.

The new Canon EOS 50D comes in a few hundred dollars less than the Nikon D300 and D300, but the beats in the megapixel race (15.1MP vs 12.3mp) and, therefore, called for a higher maximum ISO (12,800 against 6400 ). The D300 on paper seems a better AF and faster frame rates are, but someone new publications on the market will be long and difficult the cheaper, higher resolution, higher ISO Canon.

A few weeks later, another shot with the full CanonFrame EOS 5D Mark II also has a price a few hundred dollars less than the Nikon, is aimed at - the D700. Offers compared to 21.1 MP Nikon 12.1 MP, while the maximum equivalent of 25,600. Once again, the D700 has a faster frame rate, etc., but from a marketing standpoint, Canon has today a strong platform to go after the serious amateur photographer / prosumer, especially if they are not shooters.

However, it will be better. The end of August, the Nikon D90 - the first announced DSLR camera with video Capture, sporting a full 720p. The ability of SLR lenses for video capture and use of a very shallow depth of field is significant - it is not a function for everyone, but for some it is huge, and it could save tens of thousands of dollars available for devices video. Less than 3 weeks after the thunder from Nikon, Canon, again with the Canon EOS 5D Mark II, a sport full 1080p video capture mode in a prosumer camera (compared to the more basic model Nikon D90). Obviously> Canon is also serious video and seems to have the superior system.

Then there are the 24.6 megapixel Sony that shipping will begin in a few weeks.

So far Nikon has once again push the megapixel race, trying to sound, not to slow the flow of work and a higher megapixel camera is not necessary. Higher megapixels also show problems with the lens to cause problems of diffraction and the introduction of a new set of problems. Very few people really need more12 megapixels, but the average user or a beginner does not know. Listening to people in marketing, and make the comparison of bullet points on the websites of the cameras for their decisions. In terms of marketing, Canon now has the upper hand in the semifinal of serious amateur / pro-market. Nikon has to educate respond - with a series of new products or with an aggressive marketing campaign for consumers, because megapixel play does not matter. Experience has shown, time andonce again by many different companies, the introduction of new products to meet demand is almost always cheaper and / or more profitable to try to re-educate the consumer.

These are exciting times in the world digital SLR, Canon has a year to respond to the Nikon D300 and several months to respond to the Nikon D700. A response from Nikon will, maybe not this year, but as it should.
