Errrm lets not slate the 85 F1.2. Its slow to af but so is a Howitzer tank and I'd like to see your T90 fire at that!![]()
I'm not saying it's a bad lens but unless I could think of a reason for 1.2 I REALLY wouldn't have one, would spend the left over cash on a 135L

In regards to the question. If your history serves you well you will have seen me **** off the 50 F1.8 for EXACTLY this reason. Mine has fell outside of its case because its an awful constructed lens. I know its cheap but 90 quid is 90 quid.
The reason this has happened is that the clasp is likely to of come loose or broke or the paper thin rings around the case are no longer locked into place.
Its not reliable and I threw mine in the bin after it had happened because I couldn't prevent it from falling out again. It took a week or so but it kept doing it.
Yup, it's a craply constructed lens....that delivers great results. It's been fine and mechanically sound until now (it was quite a knock)
Think I'm going to ask him to replace it, I can't rely on it now

Almost tempting to dismantle the old one out of curiosity!
