Oly C3030/PT-010 vs. C5050/PT015 in Photography Gear and Technique Posted December 16, 2003 Thanks for the info -- I think you both sort of confirmed what I suspected. Since I posted the question, I've actually decided to go even cheaper -- given what I already own. I have an old EWA Marine UFGM or something like that, designed for handling an SLR + 'potato masher' flash. I purchased a cheap used Sigma 50mm Macro for EOS mount, and I'm going to take my chances and stuff the EOS 10D+macro lens into the plastic bag, along with the big flash. The flash will be completely manual, but I figure that with digital I should be able to tweak the exposure pretty quickly to get it right. I'll just have to hope that the thing doesn't leak. I've used it several times before with an old Pentax SLR, and it seems to hold up fine. Undoubtedly the first leak will be with the 10D inside. Again, thanks for the help.
