You can use a hotshoe-to-PC adapter to connect to studio strobes. You do have to be careful, however, with your selection of studio strobes. The trigger voltage cannot exceed 6 volts DC without risking damage to the camera's switching circuitry. If you get studio strobes with a higher trigger voltage, all is not lost. You can get a special hotshoe-to-PC adapter from a company called Wein - their SafeSync product line. They reduce the voltage seen by the camera's switching circuits. A standard adapter runs about $10 (US), and the Wein SafeSync is more like $50 (US).
I would suggest that you look at AlienBees for lighting equipment. They have one of the best product lines in the low-priced category that you will find, and their service - both pre-sale and post-sale - is second to none.
You can only buy their product directly from their factory - either through their web site http://www.alienbees.com/index.html
or via telephone (877) 714-3381.
No, I don't work for them. I'm just a very satisfied customer. You will find lots of satisfied AB customers on this forum. There are other brands, but after a lot of comparative shopping I chose the AlienBees products.
