Hi Jose -
I'll see if I can resurrect that article.
I do recallthe results were surpsngly similar, although, as someone pointed out, at the shutter speeds I was using, the ramifications of the mirror slap would be somewhat reduced, and perhaps testing at say 1/20th or 1/30th of a second would be a better guage. regardles, I just thought the results were interesting, because the mirror response of the Conatx was always described with terms like buttery, while the H was described as an earth moving slap. I don't have feelings one way or the other, I just like objectivity and looking deeper. If I can resurrect the article, I'll post here and re-link it to the original post.
