About a year ago I bought my 50mm (SAL50F18) and since then I let it on my camera (wich is a SLT A37) almost all the time.


Yesterday in a attempt to make a timelapse I tried to set my camera in other modes beyond the Program Auto but the camera returned me the following message:



Invalid when AF/MF Select is set to Autofocus. Available with Manual Focus


Is that had any relation with the fact that I almost never disassembly my lens from the camera?


Because I can set to A/S/M mode when I try to use my 18-55mm (which I use sometimes)


And yes for both I switch the lens and camera autofocus to MF, actually I just shoot in MF.
