Anyway regarding borrowing of lenses, although ur friend said he is willing to lend u lenses, it doesnt mean he will lend u all his lenses. What lens are he lending u? Is he gonna borrow u his expensive L lenses which cost thousands? Or just those sub $100 lenses like the 50mm prime?
My gf has Sony alpha body as well. She borrows lens from me, and I never lend her my $2700 Carl Zeiss 24-70 f2.8, nor my $3000 Sony 70-200 f2.8, instead i lend her some of my cheaper lenses. So how far will ur friend go for u (in terms of loaning lenses)?
