Hi everybody.
i have some qns in mind regarding DSLR.
1) i saw on the viewfinder of a canon 550D that there are a total of 9 AF POINTS. under auto mode, when i aim at direction and hold the shutter down halfway, i saw 5 POINTS lighted up in red. and when i adjusted to manual focus, there is only 1 point (which is at the center) lighting up in red when i hold the shutter halfway down.
so what does it meant when the 5 points light up? can anyone explain to me simply?
the next thing i knew when i shot using manual focus was that, the item which i placed the 1 and only AF point at, was the sharpest,while the rest of the part of the image was pretty blur.
so does it meant that those areas which are targeted by the lighted AF points would result in being coming out as the sharpest part in the image formed?
2)is it very very important to have image stabilizer i knew canon and nikon built their IS on the lens. so i was thinking if i were on budget, and bought a non-is lens, will my photos taken be ultra lousy? does the IS really play a big part?
