Bro, manual focus can do some things that auto focus cant..lik focus on one object and leave others blurr.. snap mini mini objects and taking fast moving objects i mean really fast which af cant cuz the shutter time is controlled.. rite?? mayb i'm wrg.. well i'm new.. tats why i'm opening this thread for advices and tips on photography.. AF surely hav it's own advantages..

yet i still wan to experiment and try new things.. i'm keen and willing to learn bro.. as long u're will to teach i'm willing to learn.. u can always start to teach me with af then tell me more on mf.. i'm using a 8mp sony cybershot camera.. anyways to improve my photography shoots?
i try my best to make u understand more

1) manual focus can do some things that auto focus cant..lik focus on one object and leave others blurrthat's not the effect of manual focus, it is the aperture, (aperture, the hole of the lens that the light passes thru),
the bigger the hole, the lower of the depth of field, focused object is clear, out of focus area, often called as 'bokeh', a Japanese word for blur.
Google
Aperture and
Depth of field, u sure can learn more on there..
just some conclusion for you :
things that affect depth of field (DOF) (High DOF, less blur background)
1) Sensor size - Point And Shoot camera has small sensor size, thus the DOF is high, that's why u cant have a very blur background.
while the sensor size of the DSLR is bigger, the DOF is lower.
2) Aperture - measured in f/number, f/2 means bigger hole than f/18, = low DOF, = blur background.
3) Focal length - that's the Zoom in point and shoot and prosummer camera, higher the zooming, the more blur background.
4) The distance between camera and object - The closer the camera to an object, the lower the DOF, the more blur the background, that's u see macro shot have a very thin DOF.
2) snap mini mini objects and taking fast moving objects i mean really fast which af cant cuz the shutter time is controlled.. rite??Correct on the the mini / micro objects, but it all depends on how close, ( the magnification ratio) of your camera / lens can produce,
I am sure u have times where it cant focus on a object that is too close to ur camera right ?
Not really on the fast moving objects, if AF really fails on fast moving object, the chances u can get it focused with MF is very low, unless u are practiced very well for MF, u know where and how much to twist the focusing ring for the distance between u and the object, and ur reaction must be fast too.. BUT, you can only do all this with a DSLR, where u can see it clear with the optical view finder, not those digital screen.
Most DSLR AF is pretty well, and it gets better when u climb one level to the another. even my nikon d40 able to snap some flying birds, fast moving cars. Just that you need some practices and skills.
and lastly, not to disappoint you, but, MF only works well with DSLR.. no even on prosummer, but the good thing is, you dun really need MF to improve your shots.
You can improve you shot, even with you 8mp cybershot compact camera, things u can do :
1) Composition,
Google the infamous rule, Rules of Thirds.
U can use AF to focus on the object you wan, the compose the frame, eg, the object on the side of the frame instead of the center.
2) Angle of View,
Don't snap photos with normal eyes level, get high or get low, create an interesting angle of view.
