I am selling off my 35mm equipment as we have a new baby who needs space and I have not used any of my 35mm gear in 6 months. I want to give someone else the chance to use it I personally used this TLA360 with my Contax RTS III I wrote to Kyocera and got a brand new instruction manual that is included as well This flash is most notable and sucessfully used with the Contax 645 AF medium format camera. I believe that this combination is quite simply the absolute best medium format system available today This TLA 360 flash unit is in fantastic condition (see pictures below) with almot no signs of wear what so ever. It comes with the original Contax soft case. This flash was almost exclusively used as a studio flash, and has only been outside 3 or 4 times in it's life. Again, is in fantastic condition! The TLA 360s output power is huge, (118 feet at ISO 100), the accuracy of exposures is flawless. It will work with both film and digital cameras in the Contax line. The reliability of this unit is consistantly perfect just like the rest of my Contax line of photographic equipment The TLA 360 is very similar to the Nikon SB-24 except that it adds the second fill flash head in the front and the sync pin lay out on the hot shoe match Contax camera hot shoe pins for TTL flash metering with the Contax line of cameras. I believe that both the TLA360 and the SB-24 were manufactured by the same Japanese company for both Contax and Nikon with only minor changes for each brand If you have a Contax Camera then you must get this flash. Works with many Contax cameras. It is powerful enough for most jobs and so reliable that you set it and pretty much forget about it. It works flawless. It is pricey but worth it....then again all Contax camera equipment and accesories are pricey but worth it for comparison, I found the TLA 360 available new on amazon dot com for $903.63 This TLS 360 is used but in excellent shape for bout 1/3 the price.
