Sharp-edged inflexible plastic frame, which can be compressed only bad, this (apart from the plastic flash) has no ribbing or counter-stop for the lens and the gumming in the entire action even "einschneident marked". For this purpose a frayed thread, in which one the lever (which are rubber-coated, why only?) Can put into it, but do not tighten. For the price a little Vernüftiges would as certainly have been possible - but it is useless.
