I usually only use long lenes as I really only shoot wildlife. I found this lens secondhand and so gave it a try.
I was very impressed, the build quality is very good, the zoom ring is very smooth and the optical quality is excellent.
The hood is physically attached to the body of the lens and cannot be removed but this is no bad thing as the front element is a dome shape and sticks out the front of the lens.
In terms of negative points, the AF is very noisy and is not a hypersonic motor. However as this is mainly a landscape lens slow AF is not really a problem.
When attached to a D30/D60 it becomes a 24-48mm which is usually wide enough.
I attached the lens to my EOS3 and WOW, 15mm on a full frame camera is amazing. I ran a roll of film through the camera for the first time in 18 months and was impressed by the results.
