Yes it would be. It's not a sentence you get to write, or read, every day either...

Well done indeed!

We now await Lilly's new challenge...

The Dissolving Green Light

It's in a consistent position and looks like some debris on the sensor.

Using a small aperture, if you take an image of a blank wall or even blue sky then any dust spots will show up.

The SR system can be used, several times probably, followed by rocket blower and finally as a last resort by physical cleaning.

I would use the Pentax kit (no surprise there0 but if you use others be aware that the K10D sensor has a special coating that may potentially be damaged if the wrong liquid is used. I have no idea which is the right liquid...

Hand inspection is the thing for films if at all possible. If you use a film safe bag then it will show up as a suspicious blank area, so the operators may well turn up the intensity so they can see inside....

My experience is that slow films are not particularly vulnerable to low dose X-ray scanneras, but it would definitely be unwise to put them in hold luggage.

As cool as possible, but there are limitations to what you can do. Keep the film in shade, enclosed is some sort of insulated container.

We survived 50C in Egypt with doing that with no discernable effect on the film. At least not for the relatively short times involved.

Typically adapters exist to enable M42 screw fit lenses to be used on a variety of bayonet cameras.

When manufacturers introduce new lens mounts they aften offer an adapter to allow the old lenses to be used.

Pentax have made Asihiflex to M42, Leica screw to M42, M42 to K bayonet adapters, thus keeping good faith with existing users.

Almost any adapter could be made , at a cost, by firms like SRB, but the problem tends to be keeping infinity focus. Sometimes lens elements are included in adapters to solve this problem.

Hope that helps!

It turns a 50mm f2 lens (for example) into a 100mm f4 that focuses to the same distance as it did. This makes a great portrait/macro combination and is one of the ways to get the best out of a TC.

A 100mm f4 macro lens would of course be much better, but a bit more expensive...

I agree, most teleconverters are pretty dreadful. Coupled with inexpensive zoom lenses they become utterly dreadful. Much better to crop the original image instead.
