本人新上會，手上存有數支 n 牌 及pt.牌鏡頭，賣不值錢，棄更可惜。請問各 c hing 可否加換轉接環後適用於新機上，另換環後自動功能是否仍然可以操作呢？何處最多轉接環賣呢？請各ching 指導，謝謝。

鴨寮街同旺角星際都有接環賣...

有好多接環都有合焦晶片, 所以應該冇問題.

go to

goto the bottom, there is a table, if u use EOS body (44mm)

those lenses > 44 + around 1-2mm should be ok to focus to infinity (without adding a glass element inside the adapter)
(from Pentax K to below)

DO NOT buy those adapter with lens element inside the adapter, because the quality is not quite acceptable.

The cheapest adapter is M42 to EOS body ($50 @ SSP)

合焦晶片 is less useful if live view is available in the camera body
