Hi all,
I just bought the above lens. Tried shooting with the lens and I realised that the pic seems to be soft at 200mm compared to 135mm, both shot at f2.8. Is this normal?
And there seems to be a 'black dot' or dust inside the lens which I cannot clean it. But when I took a 'blank' picture, I can't find the dot. It is alright? :dunno:
