How to take tack sharp pictures?

[kenjiurban]

hi, i suppose this is the right place for me..
i've seen tack sharp image on dpreview.com regarding the canon 350d kit lense (18-55)
how do they do that? i cant do that even at f8/f11, so on...

there are 7 af points in 350d right? which do you use? the center point or all of the points?

what are the purposes of that 7 points?

i only see 1 person's statement because there was one post that was ignored. very soothing for eyesight.:thumbsup: . for the threadstarter, for tacksharp pics, the subject has to be in focus. it is independent of the aperture used.

handheld? what's your shutter speed? what kind of subject?

• focus on subject
• use your lens sweet spot
• make sure your subject does not move
• make sure your camera does not move
• or use a fast enough shutter speed to freeze motion

when point 3, 4, 5 failed, use flash. :bsmilie:

A very concise and accurate list of points. Its really as simple as that.

If you still can't do it, maybe your kit lens is a dud.

Otega, how to find out where is the lens sweet spot?

most lens perform best at 2 stops down from wide opening, 4 corners are never be a sweet spots.

steady hands i guess, or maybe try using a tripod

Focus using the center focus point and confirm focus by pressing again the shutter button, make sure its still in focus. Then check the shutter speed at least 1/60 seconds for hand holding the kit lens. And press the shutter button down slowly. If still cannot check whether the lens has front or back focus problem.

1. Good tripod and head + cable or electronic release.
2. Alternatively, IS and qigong.
3. Make sure subject don't move during exposure.
4. Make sure ground don't shake during exposure.
4. Focus properly on subject.

Mirror-lockup before exposing.

beside the above, sometime can cheat a bit by increase sharpening setting in camera, or using photoshop to sharpen the photos. :embrass:

the standard setting for any pic to get the most perfect results - ISO1600, 1/4000sec, f22, mount on manfrotto 055 tripod with a brick tied to the centre column and use MLU... :bsmilie:

Buy a 50f1.8 and stop down to f4 or smaller aperture & then mount it on tripod with cable release and shoot during daytime.

I guess as long as u focus on the subject there is hardly any chance that the picture will not be sharp.

better to use a WA lens and the hyper focal distance
for maximum DOF
