I have this old but very nice mic. Old days I recorded audio to the camera or recorder. Nowadays I record to iPhone so I do not have extra recording device and cameras are action cameras usually without 3.5mm jack.

What I want to do now is to resolder the plug. But I am not sure do I need to add 4.7k resistor or not? Or even will it work at all?

Yes, it will work just fine because it's a condenser microphone.

A picture should be worth 1000 words:

    \$\begingroup\$ So should I add .05uF condenser or condenser on the scheme is one in mic? I have this adapter ae01.alicdn.com/kf/HTB1.E45KXXXXXbAXFXXq6xXFXXXm/… But it does not work with it. Although I can see resistor in the jack. \$\endgroup\$ Jan 2, 2017 at 11:03

    \$\begingroup\$ I've got an answer from Sure tech support. sorry but the mic is made to work on a mixing desk or a wireless System. These devices provide Phantom Power (48V@Mixing Desk / 5V@Wireless System). Because a smartphone only Provides 2,7 Volts I don't think that it will work. \$\endgroup\$ Jan 3, 2017 at 5:31
