Thanks heavens you guys aren't oversensitive....which is actually me misquoting deliberately a quite nice line in the first episode of The New Avengers.

Monk: "You will be shot at dawn!"

Steed: "Thank heavens you broke it to me gently."

Dan is back.

Make a report and it will get sorted for you.

Sounds interesting, but unfortunately the advice changes just as one moment eggs are bad for you, but at the moment they're good for you.

Sometimes even the same edition of the newspaper has totally contradictory stories on the same day.

Anybody who takes it all seriously must be so confused....

The upshot of all this is that the traditional advice with a full frame camera would be with a 300mm lens you would need a hand held speed of at least 1/300 sec.

With an APS-C sized sensor you would need 1/450 sec, because you have effectively magnified the image 1.5x

Frankly, often these speeds with long lenses might not be enough to guarantee very sharp images, but SR now comes to the rescue and does seem to help significantly.

Kit is best kept dry and well aired which helps prevent the mould growing. The fungal spores are everywhere in the air, but they take hold when enclosed in warm damp conditions, especially within a leather case, drawer or cupboard.

Also drawers and cupboards are not good as the wood glues used can cause problems with the chemicals that they leak into the air.

Apart from the kit I keep in my Billingham bags, ready for use, everything else is on open shelving in a dry centrally heated room.

Well we were fiddling with an image restoration till 2am, once you start it sort of captivates you....

Then up bright and breezy at around 7am, it really depends on how much sleep you need.

Some are fine on 3 or 4 hours, some need a good 9 hours...personally I just go with the flow as it does change from day to day!

Unlike Rollei, where serial numbers are fairly well known, the Pentax serial numbers are largely a mystery known only to Pentax. Even sequences may be out of order, may cover more than one item, and could be a bit of a problem to disentangle.

The serial numbers given in some books on Pentax are wonderfully vague.

Well the lenses are good, despite being low cost, but why not look on eBay? I actually sold two PL filters just a few days ago, and the most expensive only reached £5.00!

Still, while you decide there are plenty of pictures waiting to be taken, so have fun with that and we'll be pleased to see some when you're ready to post them.

I'm trying to decide whether to buy a 15mm lens or a 21mm.
Do you already have the 12-24mm? If not, then it's a splendid lens and much more versatile than just a 15mm.

Otherwise, the 21mm might get used more, depending on your photographic style.
