How much weight can a lens barrel hold?

Hello,

I'm trying to scrap together an inexpensive lens set, and am thinking about using a wide angle lens converter to reach below 18mm. Yes, I understand it is not the same thing as a dedicated wide angle. So far two inexpensive options are the Olympus WCON-08B (with step-down ring) or a modified Sony VCL-DEH08R (with step-up ring). I plan on using these lenses on a 67mm threaded Pentax 18-35mm lens.

These lenses both weigh 12-14 ounces (340-390g). I'm wondering if this kind of weight could damage or bend the lens barrel?

Thanks.

I wouldn't shake em *around* with all that weight on there, but twelve ounces of pressure probably isn't that much on a lens of that age.

I've been thinking about playing with some add-on lenses, the weirder, the better, myself, actually, as long as something interesting happens. Haven't been too concerned about the weight, though I was thinking of more ordinary lenses, (of smaller diameter) at that.
