hi
i'm a new member. i regularly check the site for tips and info.
i'm really chuffed because i've just bought my first LF camera- a stunning linhof technika master v with a spare body and 4 lenses (all of which are linhof)

65mm,90mm,150m and 240m

ive found, though, that the lenses aren't perfect.
they all open quickly but take forever to close, well at least another second or two! does anyone have any thoughts as to what the problem might be? do you think i'll need to buy new lenses?
the guy i bought them from hadn't used the euipment for at least 10yrs, could this be a factor?
i apologise if this problem has been covered already, ive had a look through the threads but haven't seen one with similar details on.
