現有支50.4及18-250，想問A850能用嗎？Sony ff 机有専用鏡頭嗎？如canon mk2比較又如何呢？

18-250唔係FF鏡,都裝到落A850,但浪費左部機

那些是FF鏡？点分呢？

FF lenses are normally bigger in size (with the same focal length and aperture). For Sony, you cannot see from the model number to tell. But you can check with the specification of the lens and it tells whether it is an APS-C lens or a Full Frame Lens. The list of lens shown in this website has indicated whether they are APS-C lenses or full frame lenses.
