1. A1 battery (spare) ** (Can't confirm. Heard from reseller about $130-180)
2. UV Filter for A1 ** abt $10.30 Hoya
3. Cir Pol for A1 ** abt $20.60 Hoya
4. Ext flash for A1 ** srongly recomment HS 5600 (D) for serious shooting $540.00 - Option B: HS 3600 (D); rem to buy the 'D' model so that it can sync with your A1 in ADI & TTL modes. Avoid 3rd party flash. Minolta Cameras are sensitive- other un specified flashes will ruin your cam utterly in the long run. Unless you have already put a fixed life-span on it.
5. 1GB CF ** Depends on brand and speed. Abt $500.00/++
