Yes, simple CLA is sufficient if the fungus hasn't etched the coating. If the coating is damaged, affected elements will have to be ground, polished and re-coated.. based on the value of the lens it may not be cost-effetive.
Contact John Van Stelten at http://www.focalpointlens.com ... Immaculate worksmanship and a fine gentleman too. He did a great job on my 200mm/f4 AFD ED IF Micro Nikkor.
