Is this a good lense, I have not read any comments on it here so I was wondering if anyone here uses it. I would like it for indoor sports, I have been offered a near new mint condition example for the stunning price $850 USD with hard case & lense hood. The person who is selling it has sold off all his Canon gear and has given up photography this is his last lense.
I can't find any info on it on the Canon webpage, is it still in production, if it isn't when did production stop.
. This is the page from Canon Museum.
