This one was a gem, absolutely gorgeous to use!

Fair enough. You could have a professional clean done, but the rocket blower should work in most cases, eventually....

Pentax make a cleaning kit, but there are others. Extreme care is a good maxim I think, but plenty of users do clean their sensors. Some complain afterwards of streaks and scratches, so I avoid it.

In fact, I've never cleaned a sensor from the *istDS onwards.

Unfortunately debris gets everywhere. When we used film we had to "spot" prints to remove white spots, so with digital it's much better than that at least.

Use the dust removal system of the camera several times and if that doesn't work then hold the camera so the opening is pointing down, open the shutter using the sensor cleaning setting and use the blower.

Be very careful not to put the blower too close as the sensor must not be touched.

If all that fails you will need a contact cleaning kit.

Please watch the language in the forums.

I suppose it might depend upon the depth of knowledge of a potential thief, but I wonder if we think the Aluminium finished Limited lenses will be more or less desireable than the black ones?

I wonder if some might just equate a metal finish with much older lenses, probably not of much value. Some others might pounce like a moth to a flame...

Every now and again I run through the Leads to Deals section and remove any where the original items is no longer available. This keeps the items linked to as current as possible. Sometimes this pruning will mean a dead thread is removed almost immediately, sometimes it wiill be a little longer!

I thought it sounded as though you had something on your mind Stefan. There's no general policy on that, it depends on circumstances. If something is unavailable there's little point it being flagged up. Sometimes they come back into stock, sometimes not, but it's not kept track of in that way.

Never force anything - it should be as smooth as silk. Something needs readjusting and maybe already has been, but to accomodate a loose fitting Sigma lens.

This has gone totally off topic now and there is already a "pointless thread" so this one is being closed.

There is no such policy, it depends on individual circumstances.
