Question What to look for in a digital camera

i want to buy a digital camera but i have no clue what to look for in one. what makes a camera good? it can only cost around $250 canadian.

i'm going to be buying one not next paycheck but the next because i still have a bit of my computer to pay off.

i don't really want anybody to look one up for me but links to examples would be nice.

The 7.2 costs about 50 more than the 5.1, it comes to about 300 english, plus 150 for the underwater case and about 100 for the 1GB memory card im gonna get...

about 550 english for the complete camera (with 40m underwater case)

well, thats what gives you clarity in your photos, so thats the most impoartant point, also you have to get a good manufacturer, like sony, which uses good technology in their cameras, some cameras have a delay, which blurrs the shot, which isnt good... also if your taking a picture of something moving, then the delay is bad also...


i cant think of anything else... if you want a really thin camera, your going to be paying more for it... but the thickness really isnt an issue for me...



yeah, the one im getting is expensive, but i need a good digi camera for diving, and it would be usefull for next summers trip to have it...

its not just megapixels that matter though:

MEGAPIXELS:

Megapixels don't really affect the quality of the final image, but the size of the image.

For instance, a 2 megapixel camera will take a 6x4 shot.

CCD SENSOR:

The CCD which captures the image is also very important as this is what actually sees the light and is what is behind the lens to focus the image to digital film.

So when looking for a camera, it is also good to look at the Sensitivity rating of the image chip that takes the film. A higher ISO number means a higher sensitivity, and this also means you get high speed of shots, since it doesn't need as much light to capture the final image, and so this is good to look out for for someone taking fast shots.

The right lens is also very important of course to focus the light onto the sensor chip:

Even with a good chip, the wrong lens could produce devistating results... like chromatic aberration and vignetting...

These can present themselves as halos of light along edges of objects, or dark patches in the corner of photos, and some good optical lenses can outweigh some of the minuses of a low resoloution sensor by increasing colour depth and detail of the picture, telling you how important this is to get right

I'd say to go for a glass lens and opt one of the big brand name lenses if you can. Panasonics Leica, Sonys Carl Zeiss, or Fuji's Fujinon, though for that price, I'm not sure if you could get one of these lenses or makes though it would make a difference in image quality.

FOCAL LENGTH:

Also look out for the camera lens Focal length, usually quoted as an equvalent value range for a 35mm film camera. A short focal length allows you to capture a wider scene, while a longer length results in a narrower picture angle.
So, the greater the focal range, the more versatile the camera is going to be.

OPTICAL ZOOM BETTER THAN DIGITAL ZOOM:

Optical Zoom is also very important, and this is usually about 3x but 4+ is best, and this type of zoom actually makes the lens move in and out, and change size to aqctaully zoom in, rather than a Digital zoom which will just use the built in computer to stretch and crop a certain part of the image, resulting in a sometimes stretched and dotty image.

So when looking for a camera with these stated, it is best to get one with a better optical zoom than a larger digital zoom which simply emulates the zooming in, and doesn't increase detail but decreases it, and so aim for a really high optical, and if available, you wouldn't need the digital zoom, though you might as well go for it if its there as well, but not instead of.

LCD SCREEN:

An LCD screen is also good to look out for to view the images so you can decide if you want to keep them or not, and many have 2.5 inch displays which most video cameras also have as fold out displays, and some allow you to do simple editing of the images before printing them or sending them to the computer.

SHUTTER LAG:

Digital Cameras are also famous for Shutter lag, and this is what alot of mobile phone cameras suffer from, and other cheaper models, and it is the time in which it takes for you to press the shutter release button, and for the actual picture being taken which is very important for fast shots in which, the action will only be there for a certain amount of milli seconds or less.

The most common way of determing this is how quickly the electonic auto focus works, exposure meters and auto white balance settings, so check the features.

OTHER SETTINGS FOR PROFESSIONAL RESULTS:

With Digital Camera,s most come with alot of manual settings as well as Automatic settings, and these can produce very professional results if used carefully and really poor ones if not

The S setting for example is good to look for, for fast shots, as this gives you control over the shutter speed, (1/500 for example will get a fast shot nicely in bright conditions with less motion blur)

CONCLUSION:

Alot of features though, are just that, features you won't need, though some can be useful and with that price, I'm not sure what you can get, but you should still be able to get a good camera if you follow some of these guidelines while looking, so don't go looking at just the megapixels for quality, which isn't true, but ends up being the case in most models, though isn't always the case as with cheaper cameras.

It is always best to try them out also, so if you have a camera shop, a good test try of a few might help you choose for web buying if thats what you would do. (Some of the values stated above are actaully stated on the lens on the camera itself, like for example the sensitivity, and focal range)

i hope this helps

for your basic fun photos you dont need any more than 1 megapixels for alittle more qaulity id say about 2m

unless you plan on blowing your pictures up huge and doing some real proffesional photography you would need more than 4

i have a 6m for my proffesional pics that i blow up and sell, i then have a 4m for my holiday photo's etc, then on my sony erricson k750i i have a 2m camera
