    Shame a £40 Transcend SDHC 32GB Class 10 card does fine for recording 1920x1080 HD video with DSLRs.

    "we're simultaneously seeing a strong trend in videographers utilizing HD video capabilities in DSLRs"

    Also a shame that the majority of DSLRs still suffer from a limit of 4GB HD recording even though the exFAT format should alleviate that problem. I can only assume it's a problem with the current generation of DSLRs processors/firmware that somehow limits the recording file size. There is information suggesting that the image sensors can overheat if longer HD recordings could be made so the FAT file system 4GB limit was really something that saved DSLR manufacturers from letting their image sensors limitations be known. Although the same DSLR APS-C sensors are used in dedicated video cameras, so you have to wonder how the video cameras can manage to operate without overheating. Who knows... but currently as far as I know this card doesn't really benefit DSLR users all that much, and not at all with regards to recording longer HD videos.
  3. Actually, the 4Gb or approx. 12 minute limit of video recording on DSLRs is due to tariffs. If Canon, Nikon, Sony and the like supply DSLR users in the US with video recording capabilities longer hen 12 minutes, they must register the product as a video recorder and pay more to import the product. This is unfortunate, since this also limits the capabilities of these products the whole world over, even in Japan. Manufacturers won't make multiple product lines either, since this also increases cost and limits where that unique stock could be sold.

    Hopefully, tariff laws will change as technology evolves. We all want to use the awesome high-end lenses DSLRs offer for our HD videos.

    Thanks for that info! So it's just a cost thing.
