Does this pic look sharp and in focus to you?

Yes and Yes. Lighting is pretty harsh and direct but it looks sharp.

The X looks sharp to me.

no pic....

Oops, just saw the link. Looks sharp, but focus point appears to be the toy and the flash is harsh.

I have this combination and its amazing yours is perfect. just need to look at your aperature and focus point a little more carefully when taking pics.

The 2nd shot at F/14 looks a bit off, and the first one at 5.6 is decent but not tack sharp like I know this lens can be.

the 2nd one is using AI Servo using all the focus points....
and the 1st one is right out of the camera no PP or anything...

looks fine to me.

They are fine, go shoot more.

ok good to know my lens and camera seem good together...thanks for the reassurance guys...*-)


this is why I love this forum!

Grinchy,

First, cute girls!

Second, have fun!

Third, two things to bear in mind concerning the first shot:

I think that the focus was on the front of the little box -- it seems sharp, and then things get soft as they get farther back. This is noticeable because you were using a pretty wide aperture, f/5.6 and were shooting close up to the girls.

In a situation like this, first off, if you want more to be sharp, you would need to set a narrower aperture, say f/8, but also, if you are shooting a person or an animal or a subject that doesn't fill a lot of the frame, then you would be very wise to not depend on the camera's out-of-the-box focusing system, which is to choose between numerous points and pick one or more with a lot of contrast. This is probable what happened with that shot: the box was close to the center point and had a lot of contrast, so the camera decided that was the plane of maximum focus.

The way to overcome this is spot focus. Your camer's manual will have a section describing setting spot focus and relevant information. You would want to spot-focus on the subject's face (or on the smaller subject.

The alternative would be to focus on the face in "normal" focusing mode, half-press the shutter button to achieve auto-focus while looking in the viewfinder, and ensure that the spot in the middle over the face lights up; then, keeping the button held down, recompose and take the shot.

Two approaches, hopefully same results. If you already know all this stuff, just go to the top of my message, read the first two lines and ignore the rest!

At least that's how it looks to me!

Whoa nelly!!!!!!

AI servo will always try to adjust for movement; if there isn't any then the camera will still try to adjust the lens. The only cam I know of that won't have a problem is the 1 series. For static subjects, use oneshot.

the biggest reason I chose AI servo is because my girls wont sit still for 2 seconds...

should I be using AI focus or something?
