The two main criteria that have been rigorously pushed by most camera manufacturers these days, and worshiped by camera users are surely megapixels count and high ISO performance of the camera. I do acknowledge the importance of advancing camera technologies and that mainly revolves around getting higher pixel count as well as cleaner low light shooting with high ISO sensitives, but in all seriousness, are these two the only two concerns which most people are considering, sidelining many other crucial factors of camera capabilities? I have mentioned this again and again, when it comes to real life shooting, photography in the field is practical, and in this blog entry I shall discuss these practical importance from my own experience.
If you somehow need to produce images with high pixel count (professional photography job requirements, eg commercial shoots), or if your photography assignment require you to shoot a black cat in the dark, unlit alley, then go ahead and get the right tool for the right job. However, 95% or more of the consumers in the market buying digital cameras are NOT professional photographers, that is the truth, and these end users purchase cameras to be used for pursuing their hobby in photography. For most situations, any entry level cameras in the market (yes, I am talking about any brands now, Canon, Nikon, Samsung, Panasonic, Sony, Fuji, feel free to add in any brand of your choice) can deliver more than sufficient image quality to produce beautiful large prints, and surely stunning images viewed on any electronic screen, provided that the camera user knows what he or she is doing with the camera. There is NO bad camera these days. And if you have more cash to spend on mid-level camera, or high end professional grade cameras, with better lenses, I do not see how any cameras or lenses cannot deliver high image quality.
The main question to ask now, to decide which camera to buy: how confident are you to nail the critical shot with the camera of choice? That confidence factor is what separates a camera that can deliver.
1) Fast, Accurate and Reliable Autofocus
To me, autofocus performance sits very high on the priority list of camera considerations. Imagine, a rare, beautiful moment is about to happen in front of you. Your camera is in your hands, it is already turned on, you have set the settings, ready to pounce on your subject. Now, you raise the camera to your eye level (viewfinder), or you may also choose to use the Live View on the LCD display. As you compose your subject in the frame, you half press the shutter button to lock focus. How confident are you that you will nail that shot perfectly? Even if you have that slightest hesitation that your camera/lens will hunt, or miss, then it is just not good enough, because the best photography opportunities happen at the least expected moments, as much as you have prepared for the shots, there are these times when things just decide to happen out of a sudden and you need the camera to be able to grab the shot without failing you. Speed is just one thing, as the camera locks focus, and you press the shutter button to capture the frame, how reliable is the focusing system? Is it accurate? Is it always, always accurate? What is the percentage of hit rate? 50%? 70%? Assuming that you did not do any mistake, your execution was perfect, will the camera decide to back focus or show some other erratic behavior? You see the importance of fast and reliable focus: it does not matter how many megapixels you have in your camera, it does not matter how clean your ISO 1 million image is. I would rather have a 5 Megapixels image with high ISO noise all over the image but have successfully captured the image as I have visualized it, than a 100 Megapixels image with clean ISO 1 million but an out of focus mess, and entirely missed moment.
2) Image Stabilization
Many people may not consider this to be an important factor when purchasing a camera, but trust me, once you have used some newer cameras with latest image stabilization capabilities, there is just no turning back. The question remains the same: when you shoot with your camera hand-held, how confident are you that you do not suffer any softness or blur of image due to camera shake? Yes, maybe you have super steady hands and you can hold your camera steady, but can you do that consistently, again and again? Many people have asked me how I get my images so sharp in my blog, the FIRST and MOST important thing to do: make sure you are free of any camera shake! Some people may argue that tripods and monopods will help, that is true, if you are shooting a planned event, or a session with nothing fast changing or dynamic. Landscape shooters, or studio work with use of tripod is common. However, out of the general mass camera users, how many actually shoot in a studio, and how many would want to lug around tripods or monopods just to gain the confidence of completely getting rid of camera shake? It all comes down to how sure you are to get the shot, when you use your camera, and a powerful image stabilization adds so much more confidence into that. Being able to hand-hold the camera at slow shutter speed also opens up a whole load of advantages: a) you can shoot at lower ISO numbers, producing cleaner images. Eg using a 50mm lens, instead of shooting at 1/50sec with ISO1600, I can choose to shoot at 1/10sec at ISO400. b) you can do creative shots, like panning or capturing motion in the images without the need of using a tripod.

Love for Mr Bean
This kid was rather camera shy, and would always look away when a camera was pointed at his direction. Knowing that, I remained by his side for a few minutes, and when he let his guard down, I immediately pointed my camera at him and snapped this shot, so fast that the frame was fired before he had a chance to react to me. This is the best example to describe the need for super fast and reliable Autofocus to nail the shot at critical moments. I knew with full confidence the camera won't fail me, I just needed the opportunity to present itself and I pounced on it.
