Camco Financial Corporation

Ladies and Gentlemen:

      We are familiar with the proceedings taken and proposed to be taken by
Camco Financial Corporation ("Camco") in connection with the issuance and sale
by Camco of up to 325,000 shares of its common stock, $1.00 par value (the
"Shares"), in connection with Camco's acquisition of London Financial
Corporation ("London") pursuant to the Agreement and Plan of Merger dated March
26, 2004, by and among Camco, Advantage Bank, London and The Citizens Bank of
London (the "Agreement").

      We have assisted in the preparation of the Registration Statement on Form
S-4 (the "Registration Statement") filed by Camco with the Securities and
Exchange Commission for registration of the Shares under the Securities Act of
1933, as amended. In connection therewith, we have examined, among other things,
such records and documents as we have deemed necessary in order to express the
opinions hereinafter set forth.

      Based upon the foregoing, we are of the opinion that Camco is a duly
organized and legally existing corporation under the laws of the State of
Delaware. Assuming compliance with applicable federal and state securities laws,
we are also of the opinion that the Shares to be issued and sold by Camco in
exchange for the outstanding common shares of London are duly authorized and,
when issued in accordance with the terms and conditions of the Agreement, will
be validly issued and outstanding, fully paid and non-assessable.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm in the Prospectus/Proxy
Statement under the heading "Legal matters" included therein.

                                        Very truly yours,

                                        /s/ Vorys, Sater, Seymour and Pease LLP

                                        Vorys, Sater, Seymour and Pease LLP
