Need help understanding SX150

I think AF tracking is not available in my cam... It means, AF constantly focus even when the subject is moving.

yaah nac thats right...focus tracking is something u lock the focus and it try to keep the focus even if subject started moving

It means, it's out of focus...

There is something called minimum focus distance... In macro mode, you can focus as close as 1cm at wide angle and 1m at full zoom. In Normal mode, 5cm (I think) at wide and 1m at full zoom. When you zoom, just under the slide (zoom) in the screen you can see the minimum focusing distance.

yes every camera lens have same issue serpent...

if in macro mode the working distance is from 1cm to 1meter just try half zoom that way u come close my 50cm and ant can be focussed ...just try like this...u will learn this soon

Okay .Btw how are the pics

 

[sujoyp]

1st one is in proper focus..and seems good
2nd one is completely out of focus...try try

It's good idea to use MF when your camera is not locking AF. I always have this doubt whether the focus is at optimum or not when I use MF.

Under Settings there is safety MF that refines focus when shutter is half pressed. You can turn it on/off. It is pretty reliable and corrects upto 5cm as far as my personal experience goes

Sujoy,
2nd one is for us... Saying he is getting blurred when zoomed in (nice way of getting the image blurred don't mind about aperture, DOF and all...

Prashant,
Yeah, I remember reading that in the manual. And I have tried once... I don't how this works... I thought it will refine and set at optimum (like AF, then we can call it auto focus in manual focus ) but it doesn't.

 

[theserpent]

whats the difference in pics in shutter speeds :/

 

[sujoyp]

serpent if i understand u correctly u r asking what different shutter speed makes on a pic

if this is the question then answer is - shutter speed is the time for which the shutter of camera is open for capturing the image and light...the faster shutter speed will take very less amount of light coz the sensor will be open for light intake for very less time...and longer shutter speed like 1sec,2 sec will take more light soo that pic become brighter

a shutter speed should also be around of 2 times of focal length if u dont have stabilisation (not valid for focal length for 50mm and below) ex u are taking pic at 200mm and u dont have IS/VR in camera or lens then the shutter speed should be at least 1/400 to capture sharp shots

Ok..now im trying to click a pic of a drop of water falling down..But my click is not on the right time what do you suggest

 

[sujoyp]

you need good shutter speed for that...but if its too dark then its better to use flash

 

[theserpent]

you need good shutter speed for that...but if its too dark then its better to use flash

How much should i keep the speed for that?
P.S check my sx150 review

 

[sujoyp]

i think u need to keep shutter speed around 1/500 in daytime and if u r taking in dark use flash
