Vivitar 365 Owner's Manual

SB-5 ac adpater produces 360 VDC from 120 or 240 VAC. Recycle time is 50-60 seconds. The manual states that it is 14 seconds but that is wrong. I spoke with Vivitar tech support around 1986 and they confirmed the mis-print.

On the front of the flash is the Auto Thyristor Sensor. This small device detects the amount of light present when the flash is triggered, metering the level of illumination on the subject. The outer collar of the sensor is the mode selector. This rotates to set for different aperture ranges while in the automatic mode, or to set for manual operation. Holding the unit upright and pointed to the right, the small window on the side of the sensor shows the ranges in different colors, flash power or M for manual.

The SLI will slow for 2-3 seconds after a flash if the sensor reads the correct light level during the illumination. You can check your exposure before taking a shot by manually triggering the flash unit and watching the SLI. If it doesn't light, you can do a number of things to correct the illumination. Set the Mode Selector to a value which will allow a wider f-stop and reduce the subject and flash distance; bounce the light from a more reflective surface.

Flash guide numbers will help you calculate f-stops for exposures using the manual position or when you bounce your illumination.Measure the flash-reflector-subject distance, and divide the total into the Flash Guide number listed for the ASA film you are using. Round off the result to the nearest f-stop and open one stop wider.Example: using ASA 25 film with a camera-reflector subject-distance of 20 feet -- Guide #20 divided by 20 equals 3 (f2.8 approximate) open an additional stop to f2.You can estimate flash bounce settings in other ways. In average rooms, a general rule is to open two stops from where you would set a direct shot.OR, using the Calculator Dial, estimate the camera-reflector-subject distance and open one more stop from what is indicated on the dial.

One great lens doesn't make a new product line; and we sold lens lines, not just lenses. That's what our US dealers wanted. Typically, the manufacturer designed and produced the lens and then offered it to us. If we didn't buy sufficient quantities, that same lens was often sold to Soligor or another distributor. Soligor was our biggest competitor at the time. So we always tried to figure out how to sell what we were offered. That led to some very strange product lineups! For example, at the same time we were selling our 90-230 T4 mount, we also had a 75-260 T4, a 85-205 fixed mount, and probably others of similar zoom range. We also had three interchangeable mount lens lines: T-mount (manual aperture setting) and two semi-automatic lines: the T4 and TX, which I was first marketed by Tamron. It seems strange, but followed our business practice of trying to keep these lenses out of the hands of our US competitors. The Japanese were very difficult to deal with, didn't much value our American opinion, and pretty much did what they wanted. If we didn't like it ... well, there was always Soligor ready and waiting. [17] (ed note: both the T-4 and TX lines are known to have been manufactured by Tokina. Bill's reference to Tamron may be mistaken or may refer to lenses in the T Mount line)

The manufacturer of the type 4 T mount is believed to be Japanese lens maker Norita Kogaku K.K. based on the identical appearance of their Norita Noritar 250mm f/4.5 lens. Some collectors refer to this as the Vivitar two window preset lens.[34] Note: evidence suggests this lens was available in both T mount and M42 mount. More documentation is needed on this lens, particularly marketing materials, ads, manuals, or magazine reviews.
