小妹一向用Canon G3，自從上了幾課攝影班，識多小小攝影資料，對攝影很有興趣，最近賣了Nikon D200，新鏡頭18-200mm 未有貨，只有一個AI 50mm 鏡，Set咗非CPU，試遇4個不同的Mode (A,P,S,M) 都改唔到快門速度，全部都係自動感光後送出未的速度，希望各位師兄師姐多指敘，謝！

seems that you can only use A and M mode for adjusting aperture. I have tried one time. however, not so sure. you may ask Nikon technical support service to re-confirm. They are very helpful and patient to answer questions. Their phone number is 29029005
