The lens hood has arrived, and it screws onto the Hoya UV lens filter fine. However, it does only add just under 2" of length to the end of the camera lens (see attached), whereas your one seems to have an extra bit. Do you think this would be enough to act as a dew shield, or should I be looking to maybe extend the lens hood by attaching more material to it?

Ok good, that's bought. And I can always attach my own extra bit to it if I want to.

Can I ask what this is? It kind of looks like a home-made one, but I can't tell. And would something like this do the trick I wonder? http://www.ebay.co.uk/itm/58mm-Collapsible-Rubber-Lens-Hood-For-Canon-Nikon-Sony-Camera-Photography-/281130508615?pt=UK_Photography_CameraLenses_Lens_caps_hoods_adaptors_ET&hash=item4174af2147 I'm trying to work out dimensions for a home-made dew shield cone, and it's already frying my brain.

Interesting, thanks for that. Might try making a cone based on one of those lens hoods, and maybe a tube as well.

So I'm thinking maybe a cone that attaches to the end of the lens, roughly the same length as the lens, and widening to 3x the aperture. But then the tricky part is attaching it to the lens. Any recommendations for that? A straightforward tube would have been so much easier because it would have held itself in place unlike a cone, but then it couldn't be very long.

I've got my camping mat. Does anyone have an idea of how long I can make my dew shield for my 1100D with it's default 55mm lens attached (and fully extended)? It has been suggested that I could make the dew shield in a funnel shape (kind of like those things dogs sometimes have to wear), which could be an option, but obviously I would prefer to make a straight tube if I can, because it would be a lot easier. I suppose if I went for the tube option then I could just make it long, and then cut it down a bit more each time until it doesn't cause a problem.

Many of the yoga mats seem to be the same width as the camping mats 6mm), so I think I'll just pick up whatever I find first in town.

Thanks, I'll give those a look.

Thinking about making a smaller version of one of those for my Canon 1100D lens for when taking wide field shots, but I wonder if the camping mat material might be too thick to make a smaller version. Has anyone tried making one for a camera lens, and if it was too thick, then can anyone recommend a slighter thinner but just as effective alternative? Bearing in mind that it'll only be small, so a camping mat would be a bit OTT anyway. Although I suppose I could use another part of the mat for a scope later on.
