The 5-pin TTL connector is designed to control the Olympus FL-40 dedicated flash unit (p/n 200596). To use the FL-40 with these cameras, the optional Olympus FL-CB01 cable (p/n 200 664) and FL-BK01 flash bracket (p/n 200 666) must be used. The 5-pin TTL connector can also control a PC Sync flash or strobe system by using the optional FL-CB04 flash cable (p/n 200 661). Since this type of flash/strobe is non-dedicated, the photographer will need to manually match the flash output with the camera.

Sca 346/2AF M don't recognized on Nikon D40 like TTL

Film Cameras were NIKON TTL Nikon Digital Cameras are I-TTL. These two systems are not compatible. Film cameras did the metering in real time. When enough light struck the film the flash was turned off. With I-TTL the flash fires a quick flash and the image is quickly analyzed and the flash fires again to take the photo. With digital it is delayed and it is NOT in real time. The camera only looks at a few pixels to make the analysis fast. I hope this helps

Ttl auto does not work

Digital Camera Fully Compatible, Newly Developed S-TTL System "S-TTL" enables TTL auto shooting by an external strobe for a digital SLR camera as well as for a point & shoot digital camera.
INON S-TTL auto strobe supports any manufactures' model providing highly accurate exposure control.
Film camera era without strobe selection problem TTL stands for "Through The Lens" and TTL auto strobe system controls flash amount to provide correct exposure based on calculation by camera's internal sensor metering reflecting strobe light from a subject through the lens. This TTL system meters actual light amount reflecting from a subject providing accurate exposure.
When we start with the history of underwater TTL auto strobe, underwater camera?"NIKONOS V" released in 1984 was the first to provide automatic TTL flash control for underwater strobe SB-102, SB-103 succeeded by NIKONOS V compatible underwater strobes form other manufactures. The 5 pin electrical sync connector for NIKONOS V is most popular and widely adopted to connect an underwater strobe and underwater film camera (underwater camera/housing).
A film SLR camera has flexibility to select an underwater strobe. As far as housing has NIKONOS type electrical sync connector and properly wired, automatic TTL flash control is usable with any TTL auto strobe like Nikon SB-105, INON Z-220, Z-22 connected via electrical sync cable.
NIKONOS type 5 pin electrical sync connector and NIKONOS V with INON Z-22 strobe
Film camera compatible strobe is not usable for a digital camera!? Underwater TTL strobe circumstances have been drastically altered with the spread of digital camera among divers. Some underwater housing for digital SLR camera has NIKONOS type electrical 5 pin sync connector as same as film camera housing. Since the housing has same NIKONOS type sync connector, existing film camera compatible underwater strobe has been considered compatible with a digital SLR camera via 5 pin sync cable but happened to experience error message on the digital camera or blackout on an image even the strobe worked. Why this happened?
This is because automatic TTL strobe system difference between a film camera and a digital camera.

The film TTL auto system makes single flash while digital TTL auto system employs pre-flash type making two to three flashes. Film TTL auto strobe system starts firing at the same time the shutter opens and reflecting strobe light from a subject is recived at a film. The reflecting light on the film is metered by the sensor to determine when to cease firing for correct exposure. This process takes only about 1/1000 second.
In contrast, digital TTL auto strobe system can not calculate adequate exposure based on reflecting light from a subject since image sensor (CCD/CMOS) reflectivity is comparably low comparing to a film. So digital TTL strobe system gives preliminary flash for very short period of time (pre-flash) just before the shutter opens metering reflecting light from a subject by the sensor to calculate necessary amount of light for correct exposure and starts emitting main flash at the same time the shutter opens. Canon E-TTL and Nikon i-TTL employs this system.

When we connect conventional film camera compatible TTL strobe to pre-flash type digital SLR via sync cable, the strobe makes full dump by pre-flash signal then the shutter opens before the strobe has been fully charged resulting in quite under exposed image only with ambient light. Even two time flash compatible strobe like INON Z-220 strobe, does not fully support a digital TTL and force to use Manual flash mode.

Film SLR:
A strobe starts firing at the same time the shutter opens and quenches firing when correct exposure has been obtained.
A film compatible TTL strobe connected to a pre-flash type digital SLR via electrical cable flashes does not support TTL auto exposure resulting in synchronization only with first pre-flash or totally uncontrollable.
The birth of digital fully compatible S-TTL S-TTL auto compatible INON D-2000 strobe and Z-240 strobe works in TTL auto mode by simply setting their main dial to S-TTL position. A film camera seems to depend more on photographer's skill, experience and feel since the camera does not allow checking images on site. A digital camera allows us to check images right after shooting and enable to try to shoot again as much as we like. And high capacity memory card further allows to shoot hundreds of images. The digital camera makes entry level of underwater photography getting down and nowadays more people buy a digital SLR camera and underwater housing even they have just started underwater photography. However underwater photography gets more difficult because underwater strobe does not work in TTL auto.
INON is among the first to support digital TTL auto system with "S-TTL" auto mode equipped D-2000 strobe and Z-240 strobe.
The proper name of S-TTL is "Optical Synch TTL". S-TTL enables to perform in TTL auto exposure as same as genuine TTL strobe from camera manufacture, based on camera's built-in flash light to use as a signal to be transmitted to a strobe. S-TTL uses digital camera's built-in flash light not as a light source but as like a controller to trigger S-TTL strobe.
The built-in flash of a digital camera makes weak flash (pre-flash) before main-flash to calculate exposure. This pre-flash is transmitted to S-TTL strobe to control the strobe to make pre-flash to a subject. The reflecting light from the subject goes through the camera's master lens to an image sensor then a processor calculates main flash light amount for correct exposure.?Finally the built-in flash makes main-flash which is transmitted to the S-TTL strobe to cause main-flash of the S-TTL strobe.

Digital camera's built-in flash lights are transmitted via an optical fiber to the
S-TTL strobe to make pre-flash and main-flash instead of the built-in flash.

I have a Digi-Slave Dual Mode DSF-Is and wonder if this unit is safe to use as an flash attachment on a Olympus E-510? Now I just use the flash as a slave unit. There used to be warnings that some flash...

This flash (was designed for digital) should be ok with E-510 alough it is not a TTL flash. If u look on top of the flash mount on the E-510 u will see some extra pins these are for TTL communication the camera talks to the flash to let it know it has recieved enough light and extinguish the tube. If u put the wrong flash on the camera u could damage these connections in the camera. I suspect the flash u are suing is not TTL and should be only one pin on the bottom of the flash unit if this is the case u will be ok.Olympus is good stuff I have an Evolt e-300 if u look on e-bay u can find a new TTL flash compatable with the E-510 at a very good price.

Canon Macro Settings for 100mm lens and Sunpak 12R ring flash

Firstly, be sure to check flash voltage. Your 30D may accept max 6V so that your camera can be shot if the flash unit has higher voltage than 6V.
1. Use low ISO to keep low noise....around f/8 or more depends on your need and how much DOF you want.....Set the shutter speed around 1/125 to your max speed to stop any movement (your subject or camera itself shaking).
2. Above is set in Manual mode (iso100, f/8 1/125 or 1/250), then you just need to leave the flash to work in TTL mode.
3. It needs battery, the connection is for syncing to trigger and release a proper flash power (in TTL mode).
Hope this help!

Can I make the Vivitar 6000AF for Canon work on a Nikon DSLR?

As a manual flash, yes. Just cover the other proprietary pins and leave the centre trigger pin.

As a TTL flash, no. Canon and Nikon uses different hotshoe and flash metering.

For non-digital TTL, I would think Vivitar 6000AF is good?

A more appropriate similar product for DSLR is Suntax DRF14

Flash on ist DL

Looks like its true... Another major disadvantage. Removing TTL means removing one more hardware piece - TTL sensor. Pentax removed almost every nice feature, which needs some aditional or more expensive hardware: no TTL flash, less AF points, pentamirror... Seems like I bought Ds right in time.

Flash won't fire on p-ttl mode

The AF360 can be in TTL mode until it is mounted on a P-TTL compatible camera and turned on, then it senses the camera and goes to P-TTL. However, sometimes in the past when I got TTL and it should have been PTTL it meant that either the batteries were not connected properly (I know, sounds strange, but check the battery compartment cover to make sure it is seated properly and make sure that the batteries are all in proper position), or that the AF360's contact pins were not all making proper contact with the shoe or extension. Beyond that it could be a faulty flash. You have swapped lenses and cameras with the same result, how about swapping flash? Unfortunately that may be your problem.
