Have had an FX for a couple of years now. The only shortcoming, appearance-wise, to me is the focussing knob - the ribbed 'chrome' (I don't know what you'd really call it) on it looks cheap compared to those on 'Flexes of yore.
Any other FX owners out there bothered by this and is there an alternative that looks more like the ribbed version from the classic Rolleiflexes?
