My answer is always the same:
The best digital SLR camera is one that helps you take photos that you love.
All digital SLRs on the market today are very similar, and they all take great photos.
Comparing digital SLR cameras is a lot like comparing apples to apples. Faced with a large pile of apples, how do you pick the best one for you?
You can pick from a variety of apples because you know exactly what you like (i.e. crunchy, tart, green, no spots).
Finding the best digital SLR camera is not really different.
Discover Your Inner Photographer
Let's start with a self-assessment.
This one won't help you quit smoking or discover your true calling in life, but it should help you pick out the best digital SLR camera for you.
The question you have to ask yourself is: What do I love to photograph?
Think of this exercise as finding your photographic sign. Once you know your sign, it will be easier for you to find a digital SLR you're compatible with.
In the next section, I'm going to list of a variety of photographic styles. See if one of them appeals to you more than the others.
Action and Sports
You may not think you're an action photographer. If your joy in life is photographing children and pets, you are! They never stop moving around, and they rarely sit still for a photo.
Faces are fascinating to you. When you go on vacation you are more inclined to take photos of the locals than the scenery. There is something about the human face and the expressiveness of the eyes that is captivating.
Landscape photographers are somewhat opposite to portrait photographers. While the portrait person likes to interact with people, the landscaper is more at home in the beauty of nature without another single person for miles.
The devil is in the details - and you want to try to find it. Macro photography is for those who love the small things in life, and pay enough attention to their surroundings to notice all of the tiny details.
You enjoy prowling around in the dark or are fascinated by the way night-time can change a city. That, or you really enjoy taking photos inside dim galleries and museums.
You want your camera to go EVERYWHERE with you. Whether it's hiking, biking, or jumping out of an airplane, the best digital SLR camera for you will be small and light.
You are most inclined to pull out a camera when your small child is reaching for his favorite toy. You take photos of birthday parties, dinners, and other events that occur inside a house.
You want to be able to react on a moment's notice, and know that speed is essential to capturing the photo of a lifetime. You have a habit of waiting until the last moment to bring out the camera.
No photo you take is without some form of preparation. Whether it's a child's portrait or a still life of your favorite flower, you like to get everything set up so that the light, color and mood are just right.
