Query: Not Quite Ready to Retire Yet

Have owned several Vivitar 283's and 285HV's on the Nikon FM2 & F3HP. I like the 283 more because I don't have to mess with the zoom head. Now using a Nikon D70 with the 283. The power is not as high as Vivitar says (ISO 400 closer to 260) but I set the camera on manual and I have auto exposure with auto focus thrown in for free! Vary shutter speed for indoor/outdoor balance. For indoors in low ceilings I can also use bounce flash with great color on grand children . Newer units sync around 8 volts but use a Wein HSBC Safe Sync which allows Vivitar cord and flash bracket for off camera flash.
