I've never tried that. I don't fancy leaving a lens in the sun, drying out the lubricants and expanding all the components.

An intense blue light such as dentists use to cure composite materials might be interesting.

You could take two tulips to the wall, after all, someone else must have.

The air is full of fungus spores, all it needs is the dark, damp conditions plus some optical glass or balsam and away it goes. Keep contaminated lenses away and store little used lenses in a dry, well ventilated condition.

Existing fungal growth can be cleaned, but it may need a lens recementing if between elements and may well not be worth it. If it's gone so far as to etch the glass, then it's too late.

Sadly, over-exposure kills digital images, just as it kills transparencies.

Re-shoot is the answer for this one.

The quality of this very expensive lens will be fine, but the limiting factor will be technique. 1000mm lenses (1500mm equiv on DSLRs) need a rock steady tripod, are difficult to frame accurately and have just about zero depth of field. They are limited in distance shots by atmospheric haze.

They are indispensable professional tools for those who need them, but often disappointing for those who want to point and shoot with them.

The OP deleted his comment, which makes this thread redundant. I'll lock it to avoid running a duplicate thread on the subject.

I can assure you there is no need for Smeggy to wear a mask, we're made of stern stuff.

Two friends of mine did the mass naked shoot at Salford Quays recently. For some reason thousands of people couldn't wait to stand naked and freezing in the manchester weather.

Yes they are one and the same.

I've removed the duplicated thread on the same subject. This one got there first.

Splendid phoitography and a great argument for the need for photographers to document modern life in the same way. One day it will be gone and if it's not recorded then the future will have no knowledge of how we lived.
