Hi, I'm in London, but never seen one of their catalogues. thanks for the tip about giottos, I just went to their site and had a look. The calument one doesn't look like anything else, so I think they probably manufacture it themselves. I simply don't know how good they'd be though compared to the big brands out there and there's little info on google. The spec looks good. However, to throw a spanner in the works, their site also listed a Giottos GTMML 3260B, and this cheap aluminium monopod is only £29 but has almost the same spec as the expensive carbon monopods I was looking at:
Folded Height - 51cm
Max Height - 157cm
Weight - 0.5kg
Weight Capacity - 12kg
Leg Sections - 4
The height of the giottos may be a little short since I'm 174cm, however the more expensive Calumet (£85) and Manfrotto (£114) are only 5cm more and about the same in other respects. Now I'm getting confused by these crazy prices!
