Table of Flashgun Data

Guide Numbers & Trigger Voltage


Legal Stuff
The following table is provided as an assistance when buying older flash units. It remains your responsibility to be satisfied that a particular unit will not cause damage before connecting it to a camera. I shall not be responsible for any damage caused by connecting an unsuitable flash unit to your camera or other device.
The tolerance of cameras and other devices to trigger voltage varies between brands and models. If a flash unit or module is intended for particular cameras you are advised not to use it on others, particularly if there is more than one contact in the foot (plus the ground contact).

This list does not include hundreds of very old flash units, which it is safest to assume have high trigger voltages unless shown otherwise. Nor does it include many more modern (late film era & digital era) flash units which generally have low trigger voltages for both technical and legal reasons. The latter usually have multiple contacts and are only suitable for particular cameras anyway.
Unless otherwise stated, TTL modes in this table are of film era type and are not compatible with digital TTL

Agfa
Agfa are best known for making film and, in the past, photographic accessories and point-and shoot cameras. They withdrew from the consumer market in 2004. From the 1960s to the 1980s they made a large range of flash units under the Agfatronic name, of which the ones below are a random sample. Most have high trigger voltages and are of low value in the used market.

Boots
Boots are a UK high street chemist chain which once sold photo equipment for the point and shoot market, much of it own brand. This included some basic flashguns which may be recognised as re-branded from other makes. Low value in the used market.

Braun
Good quality units, endorsed by Leica at one time. Braun originally made bulb flash units and were manufacturing at least into the 1980s, but are no longer in production. Some later electronic units used a "Special Camera Adaptor" referred to as "SCA", which acted as the unit's foot to suit specific camera brands.

Canon
Canon have sold flash units to complement their own range of cameras as long ago as bulb units, and up to the present day. Top end units are aimed at the professional market, and entry level ones may be expected to be of a reasonable standard. Many are branded "Speedlite", confusingly similar to Nikon's "Speedlight" brand. A-TTL was Canon's earlier exposure system for film cameras, and E-TTL and E-TTLii are later systems for digital cameras.

Metz
Metz make a variety of products. Their flash units were called Mecablitz and were made from 1952 until around 2021. They have a reputation for quality and robustness, and their large hammerheads were a favourite of press and wedding photographers. Some later models offered camera dedication with "SCA" modules. Unfortunately some later models have trigger voltages close to the 24 volt limit specified for modern cameras.
Metz themselves have stated that the 45 CL units are the successors to the 45 CT units with only minor differences, one of which is that the CL units have the standard socket for an external power supply.

* The Metz hammerheads that have a TTL mode must do so via a special sync lead and an SCA (adaptor) on the camera hot shoe. This arrangement also enables viewfinder indications such as Flash Ready. They can be also be used without those facilities with a simpler sync lead connecting to a PC socket. It has been reported that trigger voltages through an SCA are lower than those with the simpler lead; this might explain some inconsistent voltage reports on the same units.

An extraordinary number of different flashgun designs to complement their cameras as far back as bulb units, and up to the present day. Top end units are aimed at the professional market, and entry level ones may be expected to be of a reasonable standard. Many are branded "Speedlight", confusingly similar to Canon's "Speedlite" brand. The numbering of the extensive SB series is arbitrary - not related to the order of introduction and certainly not to the Guide Number.
Most units have trigger voltages below 30v and many are below 6v.
The Nikon F, F2 and F3 cameras had a unique hotshoe for which the feet of some flashguns were designed, or otherwise need an adaptor.

Sunpak
Sunpak have made good quality flash units (and a few other photo accessories) from the early days of electronic flash. The larger units have been aimed at the professional market in which Sunpak were for long the main rival to Metz among independents. The table below covers only some of the units Sunpak have made, omitting most of the early high voltage ones. Some later models (mostly with "DX" in the name and around the 1990s) offered camera dedication with plug-in modules.
Sunpak model names are confusing. They re-used some names for different models, and also used different names for the same model. Most names began with the word "Auto" but I have not consistently included it here.

MX Series
114 - 134
Various ~ 200v MX114, MX118 and MX122 are basic cuboid units with fixed heads. MX124, MX130 and MX134 had tilt and swivel heads in a weird Rubic cube style. All have a single manual mode, except MX134 has two. Last two digits in the name are the Guide Number. Numerous in the used market.
Auto Series

Auto Zoom Series
2400 - 5000
Various > 200v These did not zoom - maybe it meant the manual power level could be varied. The Autozoom 2400 and 3000 were Rubic cubes like the MX114-134, and the 3075G, 3600, 4000 and 5000 were hammerheads. All had several Auto modes and thyristor circuitry. First two digits in the name are the Guide Number.

G4500
& 455
45 7v Large hammerhead. One Manual and three Auto modes. Similar to G4500DX below (often confused) but lacking module, TTL or dedication, and should be much cheaper.
DX Series
(Below)
Various Read comment -> DX Series units were made 1985-2005 and used a plug-in camera dedication module. A generic module was also offered. All except the 24DX and the ring units had swivel and tilt heads. Many had equivalent non-dedicated models.
The trigger voltage can depend on the module as well as the flashgun to which it is fitted. As far as I have been able to ascertain, the voltage is the same for all modules on any given flashgun except with a Pentax module in which case it is 5 volts on any DX flashgun. Having said that I have no data for Canon, Hasselblad, Konica or Olympus modules.

** Pro 120J seems to use same body as the 30DX, so probably 5v with Pentax module, but no data.


Vivitar
Vivitar were (until purchase of the brand by Sakar in 2008) a photographic import and marketing company which used contract manufacturers. Some of their equipment was identical except in name to that of other mid-range brands such as Starblitz and Kiron. Vivitar's higher end units aimed at rivalling Metz and Sunpak.
Many Vivitar units offer only full power in their manual mode - or need an optional plug-in module for fractional levels.

100, 161, 252, 253, 255, 272, 273, Auto215 Various All > 200v Old designs. The 283 and 285 of this series survived into later years and are dealt with below. PF

Long comment because these were the most numerous flash units ever made, partly because they were made for 21 years. It was also revived later (was on sale in 2000) but with poorer quality.
Powerful for the price when new and one of the earliest of its type, gaining a cult following despite better later designs. Some are still recommending it in 2022 but if you must have one don't pay much more for it than the postage. Had a reputation for reliability except the feet tend to break. Earlier models had a very high trigger voltage and people have received significant shocks from them; voltage was later reduced with no name change.
Tilt but no swivel. One manual and four Auto modes. Fractional manual control requires a different control module to be plugged in. Unless you are expert at serial numbers, best avoided in case you get an earlier high voltage one or later low quality one.

285 36 350v An improved version of the 283: zoom head and eliminates the need for separate Auto and Manual controllers. But lacks the 283's external power supply socket.
285HV 36 12v A further improved version of the 283/285: this restored the external power supply socket and reduced the trigger voltage. "HV" refers to the optional external power supply, not that it has a high trigger voltage. Like the 283, the later versions were of poorer quality. PF

365 48 48v Hammerhead. Uses sensor on camera hotshoe. Several Auto modes but only one manual unless you fit an extra control module - like the 283.

Yashica
Yashica made a variety of cameras and flashguns until 2005. From 1974 they had an alliance with the Contax brand and shared lens mount and flashgun connections. In 2008 the name was sold by its parent company to another that marketed electronic items, and this then produced a cheap and poor quality "Yashica Y35" digital camera which bears no relation to the original Yashica cameras.
