hello, as the title says I am in the thrilled mood of holding in my hands my first quality glass. I know that gear doesn't make good photography but since I was looking to reorganize my lenses and this one was affordable I thought it would be a good idea to grab it.
I have already done a quick sharpness test and the results are simply... amazing
During the weekend I will also do a ff/bf test to ensure that its ok with focusing issues
There are some points though that I could use your assistance since I have never owned or used a similar lens, hence being incapable of evaluating or testing it thoroughly.
As I mentioned before sharpness wise it performs great.
The USM feature is very fast indeed.
The lens seems to be in great shape with no marks or scratches and optics seem to be flawless.
The zoom ring though is a little "tight". Should it be rotating very smoothly or it is natural to "feel" the process?
The focus ring rotates smoother than the zoom one. While rotating it you can feel both ends but it rotates more than this. Is this natural?
The focus distance switch predefines a range of focus in order to assist AF in faster focusing?
Is there anything else I should check?
If I want to use a tripod should I attach the lens via a tripod ring or the camera (my camera is a 400d gripped)?
sorry for all this questioning, I am sure some of you can understand me
I will gladly upload some photos, if it is needed.
thanks in advance
