This is all I could find.

It is very unlikely that the sensor will be damaged.

A filter, which is in front of the sensor, may be damaged but it is certainly not a user replaceable part.

Your camera will need to go to a qualified repair centre to have it fixed.

Have you tried wet cleaning products like Eclipse/Eclipse 2 fluid with PecPads to clean it?

Welcome back George. Are we to understand from your location details that you live on the canal?

Sorry Graham, that was not my intention, though I agree it looks like it on second reading. I was primarily referring to the Facebook situation.

The main point about asking people to fill in a location is for us to give appropriate advice, particularly on buying/repairing gear.

If people don't want to disclose their location, even as general as the country they live in, that is of course their right.

Perhaps they could put something in the location field so that we know it's been filled in.

You are probably right Dan. I have a pair of AF240FT's that will probably be within the weight limitation.

Whether it's unwieldy or not remains to be seen but I doubt it's any worse than my current setup. I just hope that the bottom extendible arm is stiff enough that it doesn't bend too much in use. If not, I can always stiffen it up a bit but may have to sacrifice the extendibility.

I'll let you know what it's like. I just bought one because I think it'll be simpler to use than my current twin flash rig.

The LED macro light might seem OK but it's lighting options are limited to all, left half, or right half.

Using 'proper' flashes mounted to a rig of this sort you have many more lighting options. You can change the angle of the lighting, and you more output power steps to choose from.

It would be possible to use 3 X AF540FGZ flashes with this device. 1 hot shoe mounted and set as wireless master, 2 fixed to the O-rig set as wireless slave. That's a combined GN of 162, 10 times the available light output of Pentax's AF160FC ring flash. Awesome.

Its perhaps not totally accurate to describe it as a 'flash' light. I think it is designed to provide continuous lighting. If that is the case, metering for correct exposure should be very simple and accurate.

For £33.00, it's be silly to not buy one if you have nothing like it already.

It's likely it'll only be of any use for macro lighting.

Paranoia, or what?

Have you never given your credit/debit card details to a faceless person on the end of the phone?

We don't need full address, postal code, and inside leg measurement, just a general impression of "Where in the world are you".

Your loss. I'll just have to go on taking excellent images with it . Check the serial numbers of anything you go for, the higher the number, the more recently it was manufactured. Admittedly, not for many years but . . .

I have one in the classifieds at the moment.
