this is wrong. If it's a 5-pin lens then it means that it's screw-driven AF & the 330 has an in-body screw drive (it also means that the lens is quite old, iirc Minolta introduced 8-pin in 1992 but it wasn't until 2003 that they brought out an SSM lens).
If you don't have AF it's because you have a setting wrong, the AF gears on the lens are broken or being an old Sigma it has a firmware incompatibility
it's telling you that the settings that you have set are 2 stops out from what the camera thinks correct exposure is.
I'll see if I can dig up a manual that explains it.
Thanks for the quick reply, I think that there is a problem with either the lens gears or incompatibility. I forgot to mention that I forgot to turn of the AF on the camera and there was A strange grinding noise either from the camera or from the lens. I not to bothered about the AF as in a couple of articles and books it recomends using manual focus for macro work. Thanks for explaining the the other question. The shutter speed and apeture on that were actual choosen by the camera, however with the fill-flash still engaged the photos didnt look to bad ie not underexposed just a little fuzzy on focus in places but that was probably down to my focusing skills or should I say lack of. I will switch off the flash and try it again adjusting downwards the shutter speed until the MM reading is +/- 0.0 as I was at the time working at the max apperture of 5.6. If you can find a manual for the lens it would be good to know why the AF is not available.
