Sounds silly Henri but try putting a TINY drop of alcohol or lacquer thinner on each screw and then *tightening* very firmly before trying to loosen it. This works so well that I ALWAYS tighten camera/lens screws before attempting to remove them. Of course the screwdriver has to fit properly. I have a couple of drivers made for consumer sewing machine kits that sometimes fit better than any of my more expensive ones. I don't have any JIS drivers either, I use ones made by WIHA in Germany. About $5.00 US for a 000 phillips which is a perfect fit for most lens screws. Sturdy little guys too! ;-)
