oh you lost me on this one. where would even start to look for one?If you can... find a 50mm f/1.8 MI (metal mount).
On a side note: I called the company i got my service plan through BHPhoto and they are sending me a label to send the ****ty lens back to them. Once they get it they are going to send me a check for a replacement lens. At this point I am not even sure I was to get another lens like this and am thinking of putting that money toward another better lens
