FOCUSING ISSUE Nikon 18-300mm f/3.5-5-6G
Yesterday I bought the nikon lens 18-300. at night I tried to take some panoramics shots and realized that most of the shots was rather blur. Hence, I decided to test the lens. (live view test)
To do so, I followed CAREFULLY ALL the steps a pro photographer mention on his blog mansurovs.com/how-to-quickly-test-your-dslr-for-autofocus...
This is the result. Please see the photos.
My conclusion:
I think the lens I bought is damaged:
As you can see in the picture almost 70% (on live view) FAIL, my D90 mounted on the nikon lens 18-300 cannot focus, WHILE at the same distance and same camera settings the camera can focus as using the 18-55 and 55-200mm lens.
