Space saving tip...

Got a couple of small lenses rattling around in your camera bag?
Spotted this tip in a photo mag - using double sided tape, or one of those thin foam sticky pads, stick the end protective caps together and then place back onto lenses.
Here I have joined my 9-18mm and 15mm Body Cap Lens together and the combined length is about the same as 12-50mm 'kit' lens that came with the camera.
