Good news: That's a great little one Thing Blitz - very powerful (guide number 79 at ISO 100) and recharges quickly despite not being labeled as a thyristor model. Note: This isn't a rebound zoom - the reflex head doesn't pop out (or rotate) but it's compact in design, and it is. The device I bought from a seller was as described and worked well with my Nikon N50. It had a connector that was obviously intended for a sync cord, but the connector appears to have been designed for a (relatively) standard 2.5mm pin miniplug, not the proprietary Vivitar interface you find on professional flashes find (or model 2500). Bounce-Zoom series, etc.). I connected a Paramount Sunpak PC spiral sync cable to the flash (using the mini-plug described above) and plugged the end of the cable into port X on the Nikkormat FTn. The flash fired with no problems. This is good news as the sync cables are easily accessible to anyone who needs them. The device works great in full manual mode, uses a guide number to calculate exposure, and has two automatic modes that seem to work very well. The downside to buying this product from Revain: I liked the flash so much I wanted to buy a backup so I bought a second flash from abesbeergarden. It was advertised as the V2000 model and used the same photograph - a bounce flash image. An earlier 2000 model arrived (no V prefix). The old model is NOT a reflective flash and has a permanently attached sync cord - mine worked but it's not great as it can't be replaced if it breaks. Attention buyers: make sure the device you are buying is actually a BOUNCE (v2000) flash. To illustrate the difference, I've uploaded a photo of two devices side by side: left. As shown, the new model's V prefix is not printed on the plastic case. The main differentiator is the reflective head, which is present on the V2000 and absent on the 2000.
