Can I use a Nikon SB-29s ring flash on a D90? - ring flash nikon d90

As the lens diameter can be used with the SB-29, if you can use? 62mm? 67mm? 72mm?

Just curious, I'm in the market to buy a ring flash for macro photography work and achieve a closer. If not, what (profitable) type ring flash would you recommend that is hundreds of dollars!
