Old 300TL flash on a 5d Mkii

<p>Hi all,</p>

<p>Just wanted to see if anyone knows if a 300TL can be safely used on a 5d Mark II. I understand it'll probably only work in manual if it does; I just don't want to short out anything.</p>

<p>Thanks :)</p>

<p>You might get TTL working in some fashion -<br>

Refer to paragraph headed: <strong>"Older Canon Speedlite flash units."</strong><br>

<p>Thanks for this :)</p>

<p>No problem. . . his book is very good.<br>

I refer to it often.<br>

If you have Canon gear it is worth the few $ to buy it.<br>

If you don't have canon gear it s worth it anyway, as the Flash Techniques are very sound and Creative, also. </p>

<p>You will have to use it in manual mode. The comments in 'Flash photography with Canon...' refer to using this flash with film bodies. On digital bodies you must use a newer E-TTL flash (model number ending in EX) or else go fully manual. Even medium-vintage flashes like the 540EZ, which is newer than your 300TL, do not offer automatic flash exposure on digital.</p>

<p>If the flash output can be controlled using buttons on the flash itself then you can do that. Otherwise, you will probably be limited to using it at full power.</p>
