Fantastic use of iMovie. It just goes to show what tools are truly essential and which are conveniences.

This has me rethinking some of my plans for future projects.

Which bag do you use? What's inside? Which harness do you use?

I am weighing between this and the ThinkTank 40, which will let me have my 70-200 hood extended for better readiness.

If the object is cold and is brought into a warm, moist environment, the cold surfaces bring the air down to the 'dew point' and condensation forms...on lenses.

Taking a warm object into cold air will not form condensation.

Simple science.

In the old days one used to take bodies and sometimes lenses in for 'winterizing', due to lubricants thickening in the cold. I think that AF lenses resulted in decreased utilization of lubricants, along with little in the body particularly since electronics timed the shutter rather than mechanical escapement gearing.

If a temperature change isn't enough to cause condensation to form on my glasses, is it not enough to worry about in regards to condensation forming on the camera?

In other words, is the type of condensation that Canon warns about in the user manual the type where the moisture is dripping off and very noticeable, etc. If there is no noticeable wetness, there is no condensation, correct?

Perhaps its a silly question

It is NOT 'temperature change' at all. If your camera was 54 degrees and it was brought into a humid room of 56 degrees and the 'dew point' was 55 degrees, there would be condensation formed on the lens of the camera. The 'dew point' is the temperature at which condensation forms.
