Oly E-620 TTL flash compatability

[paul_poropat]

<p>Is it possible to use Olympus T-32 or T-20 with the four thirds cameras and maintain the full auto flash exposure as I have am used to with the OM-2, OM-4? Thanks</p>

<p>Here's a link for you that already has several answers regarding the units you are interested in using..</p>

<p>Thanks Greg I am well versed on the operation of these flash units (been using them since '75). Specifically I am interested in the full auto TTL operation through the E-500 and E-600 series DSLRs. Just wondering if the Oly TTL contacts interconnect between old film and new digital technologies.</p>

I had the same questions for m4/3. I now use them all the time:<br>

Essentially, unless you are using them for macro, in which case you have to use some kind of exposure compensation for the magnification factor, you can use the sensor in the T32 to meter. Any T-Series gun(s) linked to the the T32 by T series TTL cords will be controlled by it.<br>

There is no possibility of TTL metering for T-Series flash with 4/3 or m4/3<br>

However, for macro I mostly use full manual.</p>
