  Please ignore him. The sweet spot is the aperture at which the pictures are at greatest focus. It's generally two stops above the widest aperture. I wouldn't know for your exact lens. Sorry I couldn't be of more help.

  I'm glad he's out of here!

Sooo... The sweet spot is not simply the most focused area within the DOF. It's the aperture at which pictures are sharpest and varies from camera/lens to camera/lens.

  the point between the center focus (sharpest) and its closes sensor, which is poor if you only have 9 focus point camera (too far from each other. The sweet spot term came from the 45 focus point cameras where the sensors are very close together.

  sweet spot of a lens?how in the world would sensor points of the camera have any effect on that.
tim,there may be a sweet spot with your particular lens.
you said f5.6 at 125mm.could be.
maybe f8 at 160-180mm.
maybef4 at 100mm.
so if you're worried so much about the sweet spot,should'nt you be purchasing prime lenses?
so even if you find the sweet spot,is your goal to set you lens to that setting and then get closer or farther away to use that setting?
you could sit around and watch paint dry rather than worry about a sweet spot in a lens that is one of the finest made anywhere.
how ya doin slick,sam

  Derek, just where did you get the idea that the "sweet spot" was derived from focus points and sensors?? The so called "sweet spot" term has been around long before sensors and focus points. All the way back to when I started in photography... about 1970 - 71. Howdie do Sam!

  anyone has the right to shut me down slick.
my intent is not to get anyone.i am a sceptic,a moron and I challenge all beliefs.i will not be a sheep in my life.
your world of bittersweet,although a maze,will produce an answer.
you will never turn me against another member,i pick my friends,and at this point you are so wrong,sam

You were mistaken by my post if you thought I was shutting Sam. I was commenting on Derek's post not Sam's. At the end of my post I was saying hello to Sam, who I consider a good colleague here.

  aw shucks ray.
tim,ariel had it right the first time,hence your sweet spot would be f5.6 . I never read anywhere that focal lengh was a factor or that the camera body had any influence in the test results.
boy you have been very busy lately.pulling your posts,using others mini-pics to post and irritate others.
still..which camera is it?
what day is it? who is it?
yeah

  I didnot know that the sweet spot was a hot issue , the pictures are mine once and a wile I am lucky and get a good shot ,but all I wanted to know is if I had it kinda right about the 5.6 thing .All the other stuff was people putting me in check ,my mama always said "the blind will lead the blind"
