After my focus ring problem I've found that the front part of the lens is becoming really loose. So I went to the repair shop and gave them the 16-35 with the invoice. It's a two month old glass and so's I figured it would be a warranty repair. Yeah right. The first thing out of their mouths was "it's probably been dropped". And that irritates me, because by saying that it's drop damage they can charge pretty much whatever they want and if I don't want to pay for the repairs they STILL charge 40$ just for looking at it. Jesus, I'm SO tired of my stuff breaking all the time. I'm thinking that I'll just keep using my remaining equipment until it all breaks and when it's done and broken I'll quit the photography business. *X&$#**X&$#**X&$#**X&$#* I might even start a camera repair business. It sure seems profitable: even if the camera is one day old you can just say "drop damage" and charge what you want and it guarantees you at least 40$... I'm beginning to hate cameras as much as I hate computers.
