Have you ever wondered how good your digital SLRs sensor is? Or you just want to compare some models before you buy your next camera. DXOMark shows a list of cameras and the ratings that they give are quite helpful in giving you a general idea of the camera’s sensor which is one of the most important parts of a camera.
This is one of the tools you can use online to compare cameras. Explore more and you will find more information you need for your future purchase. Or just gives you a general idea of what your camera sensor’s performance is. But best way is still to try out the camera yourself and check out more reviews online.
General things you need to consider when getting a DSLR camera:
- First thing you need to consider is, what system do you want to invest in? Canon? Nikon? Sony? This is important because once you are in a system and you have bought a lot of lenses and accessories… it will be very hard for you to switch to another system.
- What sensor size do you want to settle with? There are crop sensors (1.5x, 1.6x or 2.0x) which are smaller sensors than full frame sensors. Full frame sensors will have the advantage of allowing an ultra wide lens to be used than what is possible on a cropped system. Full frame will usually have better ISO light sensitivity performance with lower noise. Full frame will also be able to retain more color dynamics. But full frame cameras are a lot more expensive than a cropped camera. An advantage of a cropped sensor camera is that the telephoto range can be further… a 300mm will be equivalent to 300×1.5=450mm on a 1.5x cropped sensor. Some people will choose to buy a cropped sensor camera first and invest on full frame lenses. In the future they can just upgrade their camera bodies to full frame bodies. The only issue is a full frame lens may not be wide enough for use on a cropped sensor and they are quite expensive.
- Megapixels, nowadays anything above 10 megapixels looks good unless you want to print super huge photos. The more megapixels packed into a smaller sensor usually results in more noise when you crank up the ISO. But it also depends on each manufacturers noise reduction algorithms as well.
- Speed, most cameras can shoot 3 frames per second. But if you are into sports photography, you might want it to be faster.
- Lens, it is good to start off with kit lenses… but you might want to invest in better lenses further down the road. Or you can just get a camera body and buy a better lens to begin with.
- Camera bodies, do you need it just for normal use? or a rugged environment? If you are more adventurous, you might need a weatherproof or sealed cameras. One more thing to consider.
- Interface and feel, do remember to try out the camera. You might like the feel of the camera differently from another model. Also try out the user interface.
That is basically what I think is important when purchasing a digital SLRs
A great website you can use to check out reviews of cameras is from dcviews. They compile a list of reviews from around the web for camera models and are listed in numerous useful ways. Check it out.
