An honest question... Can somebody explain to me how the 60D will differ from the 7D in the studio? I thought the major differences were in terms of AF, weather sealing and shooting speed. If one were doing studio work, wouldn't they in practice be identical?
In practice, as far as image quality is concerned, they should be near identical... Just keep in mind his experience and expectations of files may or may not differ than yours or anyone elses where he may not have been pleased but you could find it near perfect so take everyones opinion, including mine, with a grain of salt. =)
