I am quite perplexed when I read reviews here that say this lens is sharp. Can I assume these are people with bad eyes or novices that wouldn't know the difference between sharp and soft? I say this because mine isn't anywhere near sharp. I have sent it in once already and I don't really see any difference. The build quality is great but I find it sits in my bag most of the time because I hate soft pictures and I hate having to post process everything that comes off of it.
Has anyone here ever had one of these that they felt was much to soft and sent it in and got it back sharp? Maybe its just mine that is bad. Who knows, all I know is that it is a worthless chuck of glass at this point.
