  • The real world comparisons, particularly robustness and reliability of different SD cards is incredibly important. I don't yet have much to base an opinion on. Please do share if you do.

    • Angelbird 300MB/s write AV PRO SD cards do write at their advertised speed and so far I have not had even one instance of the dreaded error message come up when recording stops to tell you that the camera couldn't write to the card fast enough. This is the reason I stopped using several other cards in the past after buying and testing them only to find out that their write speeds were inflated and not accurate. Sony Tough SF-G4T 299MB/s write SD cards also have a true write speed as advertised and have never failed, they are slightly thicker than normal SD card because they are more robust by design to withstand being stood on, dropped, etc but why anyone would want to do this to a really expensive SD card I cannot fathom. ProGrade cards do not cut it for me as they top out at less than the 250 MB/s they are advertised as able to write at. Lexar Pro 2000x was my go-to for the last year but they do very occasionally cause a blown take when the camera decides that it can not write fast enough to the card, though when you go again they usually always then film without a problem, weird and could be a real liability if filming a live event where a retake wasn't an option. Importantly, all the new super-fast write SD cards have two sets of contact pins to be able to write faster too. Card readers need to be able to read both sets of pins to be able to transfer/dump at USB3 speeds. There are two things to beware of
      Firstly, there are loads of fake cards being sold even via Amazon and especially on Ebay so check out who the seller is first before buying, ie filmmakers would most probably never sell on fake cards, pay using Paypal or similar to ensure you can send fakes back and get your money back. Vitally important to test them quickly as soon as you get them to check that they are real before taking them out in the field to use. Most fake cards only have one set of pins though their label looks completely the same. Secondly, nearly every card manufacturer also sells slower writing speed cards, so do take care to make sure that you buy the correct card with the fastest write speed. I have another new super-fast write speed card on order and will add my review when tested.
      Importantly if you do not need write speeds of around 300 MB/s per second go with the much cheaper cards as the prices skyrocket for that extra little bit of write speed. More anon

    • @Ray Brady Thank you Ray for a very useful overview. Quality over cost. Whilst not always the case, on balance the odds are that one gets what one pays for.

  • I've only had a brief encounter with the Sony PXW Z280 camcorder, around £6,000 plus VAT. First impression is that it can mix seamlessly with pretty much any camera where megabuck lenses are not essential.

    Unlike the smaller Sony PDX 90 we talked of on the iPhone thread, which has a full frame sensor, the Z280 has three 1/2 inch CMOS chips.

    These new type fixed lens camcorders are mooted to be able to emulate an ever widening range of single perspective lenses.

    Would love to hear from users.
