Bloggers, digital cameras and pixels

Why bloggers need digital cameras

I don't know about you, but I blog on all kinds of topics from A to Z. I have travel blogs, and for these kind of blogs, a digital camera is essential. Even "political" blogs like Blog for Positive Changes which one may think should be mostly text only content may need photos as you can see from the number of photos in this post - Long March for Justice and Rally for clean and fair elections. A blogger minus a digital camera is like someone confined to a wheelchair - handicapped.

Types of digital cameras

There are various types of digital cameras. Some cheaper ones only have a view finder with an eyepiece for you to peep at the subject but you will not see what is actually going to be photographed. Others have an LCD display which shows exactly what is going to be photographed. Some have fixed lens. Some offer optical zoom. Forget about the digital zoom as it is of no use to you. Some more expensive ones have anti-shake compensation so even if you moved the camera while taking the photo, it will not be blur. The game by digital camera manufacturers is to push huge megapixel digital cameras, of course, at higher prices. You should not fall into their trap and get sucked into buying a huge megapixel and more expensive digital camera than you need. Photographers who need huge megapixel cameras are those who intend to print their photos in large format prints. Most bloggers don't need that as large digital photos uses up lots of storage space and takes a long time to upload and, more important, download. You probably have to resize downward your large format photos with a photo editor like the free Irfanview photo editor before you upload it to your blog.

This is not to say that large format digital photos are useless for bloggers. Often, you may need to crop a small section of the photo especially if the object you want was photographed from far away, and in this case, cropping from a large format photo will help to preserve the size and sharpness of the photo. This is especially useful if you don't have a digital camera with a zoom lens.

SLR digital cameras for bloggers

The best digital cameras you can get are SLR (Single-lens reflex) digital cameras. SLR cameras gives you the ability to use different lens for different occasions. This can be very handy especially if you are blogging about scientific or industrial topics. Now, if you have owned a SLR film camera before, there is a possibility that you can use your old lenses for the new SLR digital camera. This is especially true for digital cameras like Nikon D40. Nikon D40 is cheapest of the Nikon's range of digital SLR cameras. Even more important is the fact that Nikon D40 uses the Nikon F-mount for changing lenses and a huge number of lenses can use the Nikon F-mount, so you will have plenty of choices. Nikon F-mount can be used for not only Nikon lenses, but also include other lens manufacturers like Zeiss, Voigtländer, Schneider, Angénieux, Sigma, Tokina, Tamron, Hartblei, Kiev-Arsenal, Lensbaby, Vivitar, and many others.

Another factor that makes me favor the Nikon D40 digital camera is that it did not join the megapixel race. It is only 6 megapixels and I believe that is sufficient for the fussiest bloggers. If you already have some old lenses suitable for the Nikon F-mount, you can go for the cheaper Nikon D40 Body Only Digital Camera.

If you insist on getting a larger megapixels digital camera, there is the Nikon D40x Digital SLR Camera which is 10 megapixel. The choice and the money is yours.
