Guys.. nowdays we often see camera offering very high mega pixels.. 12MP, 10MP and so on.. but izzit necessary to have such high mega pixels? Because the higher the MP the bigger the picture.. dont u all need to resize it to a smaller size later on? So whats the use of it?

Bigger picture means better bigger prints. It's that simple

and of course the amount of details that the camera can take in also increases.

high MP = higher magic power ? or mana power?

^Im assuming you're being sarcastic

btw to others mp = megapixels

more detail/sharp when croping rite?

I think higher the MP, higher the image quality, you'll get to take even a small dot at the face like a nyamuk, black dot (or qi) and so on...resize photo to smaller is other talk liao lor..

not sarcastic la....kidding only.....

Can u explain more?
Thanks..

higher mp means bigger prints although not necessarily better quality... for PnS, 6mp is quite sufficient. You increase noise when you increase MP due to the sensor size... so don't get fooled by mp!

Heck, how many of us have noob friends that look at our bulky DSLRs and say "what?, 10mp only??"

I have encountered many of those kinda people eventhough I am a noob myself.

ya, u know nowadays pns could easily go to 7 to 8mp, while my d40 only 6mp..

cant imagine when someone say..walao..6mp only ???

wah, u are here oledi

he is right, higher pixels means u captured more details (details here can be information u want or noise!) and enable u for more cropping opportunity.

BUT, higher pixel on small sensor means u get noise. Let's imagine we both have a land with same area and u build a lot of buildings made it so cramped, while i only build few houses or building made it much spacious.

For sensor in PnS, like 1/1.8" size (as in F31fd), maximum MP for minimum noise is 6MP. Now i wonder how those PnS/prosumer with 1/2.5" size sensor can fit in 10MP

It's not the amount of MP you have, it's the pixel pitch that counts if quality is concerned.

As a rule of thumb, higher MP means you can print bigger photos but not necessarily better quality. Sharpness do not depend on MP, it's lens dependent.

Having more MP also means that you have more freedom of cropping should you only print 4R size.

FYI, a PnS with 12MP will never outperform a dSLR with even as low as 5MP.

Hehe gathering information ma... mana tau i could get a dSLR

I lost u in the bolded word

Yea i know.... no matter how expensive a PnS is it cant out perform a dSLR.. dSLR win hands down in many areas.

The only downside about DSLR vs P&S to me is the P&S's ability to take video.

I miss having that on my digicam.

higher mp=higher mb per picture=higher headaches occurance.

For PnS 4-8mp is enough for 4R prints. If you want to print a poster or Billboards might as well grab a DSLR or Hasselblad for higher mp.

film pawns all MPs.. lol.

actually i think we cant really compare pixel by pixel.
sensor size will also make a lot of difference.
although the d40 is only 6 mp, its sensor size is like almost 10 times much larger than conventional pns cameras.
therefore, it can capture a better dynamic range pictures with less highlight clipping than pnses.
cos if the sensor size is small and have like 12 mps, its photocells get much smaller and therefore less sensitive to light which then contributes to noise.
try comparing a 800 iso pic from a dslr and a pns(except fuji f31) then you'll know the difference.
the largest sensor for a pns ever is the sigma dp1(full frame) which is not released yet. it has a 12mp sensor but only have a 4mp effective pixels.
if you really wanna print a good quality poster sized photo, you must go for full frame and above.
one of the best to do that is the hasselblad cf-39ms digital back which sports a 39mp medium format sensor. the details of its pics are just simply stunning.

We can always get a dedicated DV cam..

That's obvious... it's better to have one set for both uses for convenience right?
