Hi, as you can see I am new here, but I have to start somewhere, my question is, are the old lenses better than the new ones produced today? Is the glass better quality of yesteryear compared to today in terms of sharpness, I am mainly asking about Prime lenses, 50mm etc. do you think that the lenses today have the same sustainability of the older lenses? Is my question too long? I'm sure the question has been asked before, but anyway.....
