sharepoint list item permission

Hi

Just curious whether there is a way to set permission level on list items. For example, i would like all the fields on my list page to be read only except for a certain field which users can edit

At the moment any members with the Contribute permission level is able to change any field / column in the list. I could change the Contribute permission to something custom and remove the Edit items permission however that would prevent people all changes

I would like like to limit the fields to be editable by only members with Full Control or members of a particular Share Point group

Is that actually achievable?

Thanks
