    Re: D7000 with Tokina 12 28 f/4

    Do you have another lens you can use? If so I would also take the same picture with that lens at the same F stop as the 12-28mm lens. If both pictures are blurry, then it is a problem with either the camera or your technique. If only the 12-28mm picture is blurry, then you may have a lens problem.

    When you try again, try a few different things as well. If you are using your tripod, use a cable release or the delayed shutter timer, and also try with mirror up. This should result in sharper images.
    How solid is your tripod, if itís a lightweight model that could be contributing to the problem as well.

    It would help a lot if you could post the photos at a larger size to help us help you. 1000 pixels on the long edge seems to be a good size and about 150-250 kb. There are ways to enable the full size image to be accessible also, but I am not up with that.

    other information that would be helpful is, did you just buy the lens, was it new, how many photos have you taken with it, and have any been sharp ? Etc.

    I have a tripod head that has movement if I touch the camera. Also check to see if there is an issue there as well.

    Thanks everone for your help and advice.
    I think I know what the problem is: I iused a monopod and not a tripod.
    I took another shot this afternoon. I used a tripod, a cable release and mirror up.

    Looks better from here. Are you happy with it ?
    I can’t see the exif data, are you linking the image from offsite?
    There is a tutorial somewhere that shows how to post your images directly into your post, it’s a better way for us to be able to look at them.

    It is indeed better. I'm not 100% happy with it but it is an improvement.
    Here is another one (F/8 - 6 sec - iso 100 - 16mm): it is indeed better with F8.
