Re: Wait just a minute...

I fear my response will not help much but my 50-135 has been behaving something like that for at least a year and half. i bought it used from a guy who sold it very cheap because he was sure the SDM was dead. I left a week later for 10 days of backpacking in Utah with the 50-135 on the camera most of the time (1500 pictures) very few frustrations.  I have taken several thousand pictures with the lens since then. The problem is that it can be slow to start up and will occasionally balk at finishing focus but it will eventually do so. Sometimes it is beautiful with a BIF but really cannot be trusted for that. I am pretty sure that it is an SDM problem but I have waited to send it in because I like it so much when it works, which is most of the time. that I do not want to give it up for a month or so. I am sure I will do so eventually. Much sympathy with your problem. Nothing is perfect - or even close.
