I got the copyright. He took photos of my products. But it may be different with product photos I did not try other photos yet. 
Yes, in a case of a work for hire..same would apply to my and my field, if I was under the employ of SG's Butthurt Inc. and developed a site, SG would automatically own the copyright, because I was on his payroll.
My question is did the photographer actaully sign over a release of copyright for you? If not I don't think you would technically own the copyright..Unless he was on your payroll that is.
::edit:: From the US copyright site:
What is a work made for hire?
Although the general rule is that the person who creates the work is its author, there is an exception to that principle. The exception is a work made for hire, which is a work prepared by an employee within the scope of his or her employment or a work specially ordered or commissioned in certain specified circumstances. When a work qualifies as a work made for hire, the employer, or commissioning party, is considered to be the author. See Circular 9, Work-Made-For-Hire Under the 1976 Copyright Act.
