Hello,although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate while using this adapter. There is no electrical contacts in the adapter ring. Full manual operation, manual focus, manual iris adjustment can be achieved with body manual exposure, aperture priority exposure. 

Could you please update us your full Minolta lens model ?as Minolta has MD MC and AF mount, K&F Concept MD-M4/3 is suitable for: Lens: Minolta MD MC Mount lens(not for Minolta AF mount: KF06.157) Camera: Micro 4/3 (MFT) mount mirrorless camera like Olympus PEN, OM-D series, Panasonic Lumix DMC-G1, G2, G3, G10, GX1, GH1, GH2, GF1, GF2, GF3, GF5, GH4, Panasonic AG-AF100 Mirrorless Digital Cameras, Black Magic Pocket Cinema Camera (BMPCC) 

HI your fujinon m42 55mm 1.8 and a sigma-z m42 135mm 2.8 are M42 mount, the item can fit your camera and lens 

No, this adapter is for the older manual focus Minolta Rokkor MC and MD lenses. If you want to autofocus and aperture control you will need the Sony LA-EA4. (the lower cost Sony LA-EA3 will electronically connect A mount lenses but you will have to manually focus.) 

Hi, we checked the Sony a6600 18-135mm lens seems 55mm, if you like this filter, please reconfirm the lens size, the 55mm lens need to order 55mm size filter,thanks.
