He is in Singapore this week to attend a niece's wedding. Better to pm and ask if he is ok with it. He has more books IIRC when I spoke to him on Thursday.
Hi and welcome,
Most of the information are available online as well as youtube on every imaginable topic. There are Ebooks if you search for it however since you are from Finland may I suggest you look into these two gentlemen who are m43 ambassadors in your country regardless of which camera that is not m43 you use as it is more relevant to you and locale.
