I have the dl28 box, wasn't it just a bundle name? aptus ii+afd3. If you read Yair's reply above, he said it won't work on the afd3.. only on the RZ. Mute point, unless there's a fix for those lines. I can't shoot in LC.
Thanks for assisting in my adventure in tethering.
Sorry - your initial post indicated you bought an RZ Pro II/AFDIII and a DL/28. If it says Aptus II on the back of the digital back, then that's what you have. In that case, as far as I know, Live Video shoot work right now in Leaf Capture (and eventually in Capture One).
