I didnt say all their products were 50% bad copies. Ive learned, only now that this particular lens had an issue with dishing out soft pictures. It was reported on the net as a quality control issue with only this product.
Your 'elvis is alive' anology apart, but arent even we discussing on the net. Not everything on the net can be just despised as nonsensical. Im sure most of us found camera labs forum via google. It depends on what you search for. And what i searched for was relevant and i found a thread of 257 reviews from customers who bought it. Heres the link...

If you do read it youll find out that there are many happy (lucky) customers who got a good copy. But there are equally large number of professionals there who got bad copies of this lens. And a large number of them who had to ask for replacements and then got a good copy. If it boils down to usage technique, how come the very next day most of these people got their replacements they were able to shoot discernibly sharper pics and be happy about it.
Now even im able to shoot sharp pics with this, but only above f9 or so. And even then after a certain distance theres softness.
Remember the amazon reviews link ive given above is from all people who've bought it and then reviewed it. Im sure people spending quite some money on an UWA lens are not novices with a point and shoot camera.
Sigma itself has tested these return lenses and replaced them with proper ones which means they screwed up on the quality control for this one.
