Such a disappointment

So contuining from yesterday... I walked to the post office with eager and also with some kind of worried feeling. Couldnt get home fast eough and try the Canon 100 f 2.8 macro. A big lense, heavy and gave me a direct feeling of quality. But... it didnt work. It focused alright, but when shooting it came up an Error 01 saying that the lens should be cleaned beacuse it lacks contact with the camera. I have of course cleaned it, took it today to a photo shop and tried with of their cameras.

One or another solution there must be. I've buyed privately on the net - a sweidsh lady living in US and shipping all kind of photo articles overseas. Like ebay you leave comments and grades, so its rather reliable.

Many words about this, but ít costed 400 euro. To be continued :)
