Originally posted by nosnoop Has any current DSLR with HD movie function been compromised in its photographic function? Not at all.
This is rather a misleading question, as there are only two of them on the market and they are first generation products. There's no way to tell what compromises will be made when this feature reaches maturity.
Already, though, I would argue that the "compromise" is that HD video is taking away time, money, and other resources from the R&D teams that would be better spent improving the features that a DSLR is primarily used for - e.g. better high ISO performance, longer battery life, better AF, etc.
I understand the need to stay competitive in the marketplace, but Confused is right - the history of dual-purpose devices proves that they are never as good as the single-purpose devices they were intended to replace (look at cell phone cameras, PDAs with built-in video players, or camcorders that claim to take good stills)...
