Many thanks for your speedy and comprehensive answer.

Do you all notice long write to card times when using long exposure times.My GX20 seems to spend a proportionally longer time to write depending on exposure length.Is this common or a fault?

Many thanks mm

Funny thing about glass is that it will still flow with time. Very old church glass is thicker at the bottom of the window than the top![/quote]Are you sure about that.I thought it was a myth.

Shim ring Play and talk to them as they will not post unless they talk to you, for security reasons on high ticket items.

I thought this thread was dead, but I have this very day, been offered a Tamron as a replacement.I was more than happy to accept.If you thought you had been forgotten about, there is still hope.

Good luck mm

I have had a lovely day today,against all the odds.These two people showed me how good things can be.I have no idea who they are so I hope I am not breaking any rules of etiquette.

Missmarple if you wanted one of the Tamron lenses, I have not replied yet, pm me if you want one. It is just my luck that the replacement offer is a lens I already have!!

Steve.[/quote]That is very kind.I have a Pentax 55-300 already so the Tamron would have been just for the close up option.I think that there is probably someone on this forum who would benefit from the long range of this lens more than I would. I would be happy for someone else to benefit from your generous offer.Perhaps someone here could PM you with their interest and the three of us could come out of this saga with a warmth of feeling we didn't have before.
Thanks again, mm

With regards to the mark on the pic and whether it is on sensor or on lens

I have no technical understanding about these matters, but I had a very similar mark on a few pictures.They only showed up when using one lens,though not in all picures.After a clean of that lens I have so far not noticed it again.

HTH mm

I'm feeling a little left out here.No Tamron offer and my order cancelled for me.I think I will have to spend the money on a nice bottle of wine to console myself.

All pins good on second reassembly I just tried scraping paint off the mount as I think I read somewhere that was a fix for something.It didn't work but I had nothing to lose.It's probably time to give up now,Idont want to ruin other bits in a forlorn attempt to make an old part work.I do not want pride and stubborness to bite me.

Thanks for your help, mm
