I need some help if I may. The instruction book for the FX
recommends on
line of flashes which will work with the TTL metering system of
the FX,
the SCA #%^ adaptor and a line of Metz Flashes The SCA 300
system. I have
a Vivitar 283 which works well as an auto strobe but not with the TTL
function. I have the Nikon 800 SB for my Nikon DSLR. While the
Rollei FX
will not file the 283 from the flash hotshot it will fire the SB
800 from
the shoe. The shoe and the pins on the SB 800 are similar in that
they
have a grouping of three connectors, yet the SB 800 has a total of
four.
The only way your FX will work fine with the TTL metering option is
with the Rollei 356 adapter and a SCA 300 flash system, the number of
pins is not significant for the purpose if flash and camera internal
computers are not compatible.
My dedicated Pentax flash works 100% integrated with my Pentax camera
flash program, it also works fine as Auto flash for other cameras
(f.e. my Rollei 35 and SL35M), the hot shoe central contact and the
flash central pin are enough to fire the flash beyond the number of
pins, I lose some functions as camera automatic shutter speed and f
stop settings but it works, however every flash is different and the
only way to know for sure is trying the flash with the camera (anyway
be careful with the flash trigger voltage).
I find strange your FX hot shoe does not fire the Vivitar 283, in
general the contact between the hot shoe central contact and the flash
central pin fires the flash, anyway you need to be sure about your 283
trigger voltage, older units have very high trigger voltage that could
fry your camera electronics, I use my 283 with cameras without
electronics for the flash, I'll try it on the Pentax after to measure
the voltage with a tester.
When I use the SB 800 results are sporadic as demonstrated by
negative
density. My questions are how does one know if another system
such as the
SB 800 will work with the FX. Is or has something been been
written?
Second: I can find the SCA Adaptor for Rollei on Ebay for $$$ but
I have
no idea exactly witch Metz Flashes will work with the recommended
adaptor.
Are there others witch will work with FX as fully TTL?
As I wrote above, the only way to work with your camera TTL metering
is via the Rollei 356 SCA adapter.f.e. If you look for Metz, Cullman,
Osram SCA 300 flashes among others, you'll find results. The newer SCA
3000 flashes seem to be compatible with the SCA 300 system, it must be
checked.
Any help will be good and appreciated.
