FM3a TTL

Sorry if this has been asked before but I'm not very familiar with Nikon

speedlights.

 

Thinking of getting an FM3a for work to suppliment the aging F2's I use in the

studio. I'm leaning towards this body for it's TTL capability and noticed it has a

button on the body to reduce flash output by one stop for fill-flash. My question

is, can I dial in less flash output through the flash unit itself in TTL, i.e. -2,-2.5,-

3 etc.?

Thanks in advance.

From the FM3a instruction manual, p. 33

"The flash-exposure compensation function of the speedlight is

disabled in TTL mode."

 

You might consider a F100 or the F5 for a more complete TTL selection.

If you are manually setting the shutter speed and f-stop on the camera the TTL flash metering is still controlled by the exposure compensation/film speed setting. This would be the way to change the amount of fill flash over a large range.

Thanks Gerald, that was exactly the answer I was looking for, although a

disappointing one.

 

Bruce: Wouldn't adjusting the ISO/Exposure comp. on the camera affect the

ambient exposure reading?

Of course adjusting the ISO setting will affect the meter reading, but it is a needle that you can judge +/- 2 stops except in low light.

 

I've never seen the need for more than -1.7 stops of TTL flash compensation. If you need less flash, then manual or auto flash mode where the SB controls are fully functional is usually more than adequate.
