The truth is that I have had this critter for nearly a year. I bought it for its intervalometer and long exposure capability to use with my Canon DSLRs, particularly for night shooting and to shoot multiple images for stacking. It's not Infrared, it's radio and works in the 2.4GHz band. Hahnel claims a range of 100m, I've tried it at distances of over 30m but then I get nervous about my gear and move in closer.
I had initially considered using Pocket Wizards as remote triggers, but discovered that the retail price of the PW cable is as much as the Hahnel full kit. Have I mentioned how much the arrogance of the PW people bugs me?
Now I also wanted to be able to wirelessly trigger my Hasselblad H4D-40 and another member at the AWESOME Hasselblad Digital Forums had mentioned that he found that Canon Rebel appropriate wired remotes worked with the Hassy. Since the Hahnel kit can be used wired or wireless I thought I'd give it a shot.
The Hahnel kit comes with cables for both the Canon pro bodies and the consumer bodies. How convenient that the Hasselblad connection is the same configuration of the 3/32" (2.5mm) jack as the Canon Rebel. So I connected the Rebel cable to the Hassy and to the transmitter. Push the button and the shutter fires. Cool!
Unplug the transmitter, plug in the receiver and walk across the room and press the button. The shutter fires. So I set up an interval sequence and yes that worked too.
Hahnel doesn't say anything about Hasselblad. Hasselblad doesn't say anything about Canon remotes. All I know is that I now have a solution for the Hasselblad that cost nothing because I already owned the solution. I got mine at Henry's, but I expect that they are widely available.
