Question: The user manual states that you can use a memory card that's up to 64GB.  Has anyone used a larger card?  128GB? Larger?
Document: Rode is sending a replacement foot for free in case I need it.Sony should make a clearer statement about what SD cards will work with XAVC-S 50Mpbs. A SanDisk at BB with the correct specs did not work with XAVC-S. The 64GB Sony card SF64UY/TQMN on Amazon Prime works wonderfully at a lower price.Sony should not have released the camera without a full manual for USA customers. I was told by Sony Support that a full manual will be available on April 15. I downloaded a 190  page Help Manual from Sony Europe.
The Iris, Gain/ISO and Shutter Speed buttons, used in combination with the Manual Dial and zebra striping provide quick exposure controls to match the intended outcome. The menu and touch screen controls are logical, quick and easy to understand. The build quality seems amazingly solid compared to my HF G20.The on/off functionality is fantastic. During normal use, just close the LCD (or viewfinder) and the camera turns off. Open one or the other and it turns on, almost instantly. Seems like something designed by Apple.
I can see using this camera for years to come. In fact, I'm ::::gulp:::: considering buying a second one. I often video dog shows for friends, and it would be nice to have a stationary one that takes in the entire ring, and then one that I use to pan and zoom to individual dogs.There's one thing that's taken some getting accustomed to -- and that's that the zoom feature is much slower to travel the full length of its capabilities that my old model.
Plus if you remove a card to transfer files you better not go anywhere to shoot video without putting it back in the camera slot or you aren't going to record anything because there's no internal memory. I don't want internal memory. I want two card slots.The shoe should support a standard foot. The Multi-interface shoe is recessed and has flanges that prohibit mounting a standard shoe without an adapter. None of Sony's adapters support a standard shoe. I ordered an adapter from The Auction Site. My Videomic Pro foot is going to be modified with a Dremel tool so that it will drop into the recessed shoe without an adapter.
I can't believe that Sony would release a $1500 camcorder with such an issue. Maybe they expect you to carry a tripod but unfortunately anything shot handheld looks like cheap smartphone footage.Also, the included User Manual is mostly useless. It is very small, printed on cheap, thin paper with very light colored ink, and it does not cover any of the advanced features like trying to figure out the various quality modes and codecs to shoot in. There is no included CD with more advanced versions of the User Manual as is the case with many advanced cameras and camcorders.Very disappointed in Sony on this one.
It should just work that way. That on/off thing is going to spoil me for any other on/off functionality. There is a power button under the LCD. I have used it before removing the SD card, but neither the camera nor the card seem to care whether the camera is on or off when the card is inserted or removed.I do have a few nitpicks and here they are.It should have two card slots. Sure I can change cards with the camera turned on, but why not two cards with roll-over recording?
That one was TOO fast, but I got used to it, and would edit out my whiplash zooms with Final Cut Pro X. With this one, it's less touchy, but I have to plan a bit more. All in all, it's probably how a zoom should be.I decided not to wait for the 4k camera, and I'm glad I didn't. The video quality here is plenty fabulous for my use! I find everything improved from my old HandyCam in this new model. I do use a tripod virtually all the time, or if I'm doing candid videography, I brace against something, so I haven't found it shaky at all in spite of its extremely light weight.
The 1" sensor, fantastic lens, good aperture range and ND filters combine to make attaining shallow DOF easy compared to the other six camcorders that I have owned. The buttons, Manual Dial and controls combine to make quick adjustments to changing conditions fast and easy. I am trying to swear off auto-exposure and auto-focus to eliminate those auto-adjustments in mid-clip. This is the first camcorder that I have owned that makes me feel confident that I can do it. The Focus Magnifier and Peaking make fine manual focusing much easier than anything I've used in the past.
I have studied, shot and edited for a week to make sure the HDR CX900 is a keeper. So here is one person's review.But before the review, let me say that some sample 1080 video can be viewed at youtube.com/user/handshakevideo under Sample Video.Here's the good stuff and then the nitpicks.I bought the CX900 to replace a Canon HF G20 because I couldn't stand the jaggies and artifacts generated by the G20. I have worked hard to create a jaggy with the CX900 and haven't seen one yet.
I could never hold the dang cam steady and I knew it would be necessary. Well, the CX900 does not have the BOSS. I thought I could get the Cam Caddie and it would be a win/win with the 1&#8221; sensor. WRONG. For me anyway. Again, I sucked at holding the little HC3 without a monopod.Size-  It is much larger than my older HC3 and my wife joked that it looked 10 years old. I for one love the size. Yes it is bigger, but with the shield on the front it looks &#8220;cool&#8221; and it balances much better than the HC3.
Answer: Hi Harold, using a memory card larger than 64GB may not be recognized by this Sony HDRCX900/B. -Ely
