Well, well, well... 5 pages run out and nobody told you that yet...!
OK lets say it all!
Don't think small... This birthday is an important one, will never be repeated! What's money? Printed paper!
Your father deserves some toy he won't loose interest in after a few months...
Macro? Did you say macro? All right, give him the best! Ready? Give him the Contax 645 toy (German, imagine!), the outstanding 120mm macro planar (German, imagine!) a TTL flash (German that one too, useless to say!) and the guy (sorry, your father) will have something to be proud of, new, excellent and fully professional for his unforgettable birthday! Need I say more?
