# Special font for only some symbols

Is there a way to use \usepackage{newtxmath} only for \sum, \int and \lambda and just normal settings for all other symbols?

thanks.

• It is funny i followed a guide there and it worked but when i change the sum and integration sign it also changes the infinity sign. It seems there is no way to get both mathabx for sum and int but ams for infty. But thanks for the link. – Simon Chemnitz-Thomsen Jun 3 '17 at 21:45
