The best to get cheapest DSLR body is to bargain. :bsmilie:
And have a network of people who is in the market or sales manager, they might be able to give u a good price. Or might even sell you at cost of sales. But sometimes, you need luck too. So good luck.
u know the sales manager of sony ????

Yeah...machine gun!!! when I use the A550, just 1 press & it burst twice! I'm like wha...I only press it very lightly & fast!

the feeling while hollding A550 is so much diff frm holding on A300.. wahaha... nice.. but hor.. i decided to wait 1 more mth.. wahaha
did you also try the 5fps mode? from what i've read, 7fps will lock the focus and metering during the entire burst, so you lose AF-C. i'm curious if you will end-up with more keepers with AF-C and slightly lower FPS =)
Which feature in particular?
I LOVE A550!!!! was thinking to get D90 but this A550 has wonderful and useful feature that you gonna love it... even if A750 is out, you will not regret having A550 first.. who knows ending up u keep both body...
depends on what you're shooting also. in good light AF-C is the way to go to getting more in focus shots.
like if you're shooting f1 cars @ SG night race you'll most probably need to manual focus & burst shoot else the cam will keep on hunting for a focus lock.
I would say the face-detection using phase detect is a fantastic feature ever implemented in cameras as a whole.
it's very fast, very accurate and it seems also to adjust the exposure settings accordingly. Great for portraits. :thumbsup:
haha the smile shutter is a little gimmick that makes all my friends go woooooo. its not really a PRO thing but well, who cares, its just to make me happy. Its also useful considering u dun need a remote or timer as it autofocuses on faces that are recognised. Perfect for group shots.

I hope not. If it's targeted at semi-pros or advanced users...
Hmm... a wedding/event photog can actually use it as a gimmick to make their clients smile... :angel:
"Hey Smile! Smile else my camera won't snap... it's got Smile shutter!"
The face detection and smile shutter functions are only available in live mode. So I am not certain if phase detection is used to detect faces, but I am more towards thinking it is contrast detection by the small sensor used for live-view. Contrast detection utilizes the whole live-view sensor for focusing which makes it possible to detect objects of certain shapes and colours. On the other hand phase detection focusing mechanism works by dividing the incoming light into pairs of images and comparing them with limited fixed focusing sensors. I'm not sure how well the two focusing mechanisms can work together to achieve face detection, but I think for A500's face detection is achieved the old fashioned way through its live-view sensor by contrast detection solely.
Still it is as fast as the Panasonic GF1 under contrast detection. Face detection through contrast focus is actually more convenient on a non-pro body which has limited focus points and is not as easy to manipulate as a pro body. The downside is that you cannot use the viewfinder to compose your image while on live mode. I suppose one would have more freedom to interact with the people being photographed instead of hiding behind the camera body.
I know it uses phase detect af, but I doubt face detection uses the phase af sensors as well. It is technically difficult/impossible to detect shapes with phase af sensors alone. Phase detection af works by analyzing light with a limited number of sensors whereas contrast detection focuses by contrast and shape with the aid of in camera computer chips. There must be a reason that face detection is only accessible through the Fn button when the camera is on live-view mode.
There is a simple way to prove this. Just try to use the face detection function to focus on a face that is located on one extreme corner of the frame where no phase detection af sensor is assigned to. If it still works then it must be face detection by contrast, at the same time with the availability of point focus by phase af sensors.
