xplatinum Posted April 5, 2010 Share Posted April 5, 2010 Is it normal behavious for a DSLR (D90 in my case) to be out of focus on DOF by around 1-2cm ? I had my doubts so I took a magazine with lots of text and placed it on my desk. Took my camera on a tripod and placed it at a 45 degrees angle and took a picture at a particular word. The part that was perfectly in focus wasn't the word i previously focused on but another word 2 centimeters below. Is this normal behaviour or is there something wrong with my camera ?

Argote Posted April 5, 2010 Share Posted April 5, 2010 Is this happening with ALL of your lenses? Link to comment Share on other sites More sharing options...
User6060 Posted April 5, 2010 Share Posted April 5, 2010 have you dropped it or your lens? Link to comment Share on other sites More sharing options...
crazzy88ss Posted April 5, 2010 Share Posted April 5, 2010 most likely a lens issue. What lens is it? it doesn't have to be damaged for it to go out of focus. My Tamron 17-50mm f2.8 needed to be recalibrated after about 18 months. Link to comment Share on other sites More sharing options...
xplatinum Posted April 5, 2010 Author Share Posted April 5, 2010 The camera was indeed dropped from inside a lowepro bag. The 18-105mm lens was knocked out of focus really badly but the camera itself seemed okay. The lens in question is a Nikon 50mm 1.8D. I tried the test with my other lens too, a Tamron 17-50mm 2.8 but it was much harder to judge because of the wider DOF. I'll try again today when I Come back from work. How much does it cost to recalibrate a lens and/or camera ? Link to comment Share on other sites More sharing options...
crazzy88ss Posted April 5, 2010 Share Posted April 5, 2010 My 50mm f1.8D isn't super accurate either. And it's never been dropped. Tamron calibrated my lens for for free. I dunno what nikon does. Link to comment Share on other sites More sharing options...
