    Hi Glyn;

    I really appreciate your quick reply. I looked at those images you posted. I have some questions that will help me make a comparison with the NX70. In my quick look, although the CA is apparent, it is much less severe than the NX70.

    * How did you obtain the frame grabs – Sony Picture Motion Browser, or via NLE such as Vegas or Premier?
    * What is the size of the posted images – height / width pixels?
    * What were the zoom settings? (I’m particularly interested in full 20x zoom images, because the CA is always worse at full zoom)

    I’m also intrigued that your camera had the soft-focus problem on the left side, and they were able to fix that. Although the CA bugs me, the focus problem makes the camera unusable.

    I did not mention it in my previous posts, but temped by a better price and the charger/battery rebate offer, I bought a THIRD NX70. I did extensive tests at various zoom in outdoor light, but only with targets at infinity. The left-side focus problem was not present, so I thought I had lucked out. I cut out the bar-code and sent it in for the rebate.

    Then, two weekends ago, I shot some indoor footage – critical – at an orchestra concert. Left side focus problem BIG TIME. Look at the NX70# shots, they are the most recent, at https://www.huecotanks.com/temp1.

    I feel really stupid. I cannot use this camera. I’m trying to get B&H and Sony to consent to a refund, I will also turn in the unopened charger and battery. I’m biting my nails and hoping that the legendary B&H customer service will come through for me …

    I’m sick, really physically sick over this problem. I’m not wealthy and this purchase tool all my savings plus a loan.

    Ready to throw up,

    Steve

    Hey there,

    Sounds very frustrating what you are dealing with right now. I had not really noticed the focus softening until I reviewed some footage and finally saw it. It was ever so slight. Perhaps on an orchestra I may have seen it as you are dealing with a wider shot and more detail.

    OK now onto the answers you needed:
    1. I grabbed these screen shots straight from my NLE (FCP) but also reviewed these through VLC straight from the card and the conclusion was the same. I convert all files from card to FCP as ProRes 422 LT.
    2. Full HD size which means images are 1920×1080.
    3. Zoom length is almost wide open, perhaps 95% wide (good enough to be fully wide).

    As I do a load of filming on white backdrops this is a huge problem for me. There are ways to help knock the CA prominence down but that is not a solution for me. Sony’s final response was that the camera, with the limited lens is within spec :). For some projects I ended up getting a small plugin called “Cheap Lens” by River Rock Studios to remove some of the CA from my footage.

    On a side note I just finished up a gig using the Sony FS100 and I have to say I am extremely happy with the results. So I have every reason to believe the CA is not just about the lens it is also about the sensor. I was using the stock lens and there was next to no CA at all. I know this is well out of price range but if this could be an option I would go with it. This is something I am looking at doing now. I mainly deal with indoor, studios and theatres which is where I need great low level light and no CS if I can.

    No throwing up please 🙂

    Hi Gyln;

    Thanks again for the details!

    Your comments about the FS100 and lack of CA are interesting. I would have assumed that a three-sensor system would have better CA than a single-chip. But, the 4/3″ large sensor on the FS100 is newer, more advanced, and possibly better over all.

    This makes me re-consider something. I *think* that the consumer Sony VG-20 uses the same 4/3″ sensor as the FS100. Even though the VG-20 is pretty much a toy when it comes to serious video, if I get it, I can start building a collection of A-mount lenses, and perhaps someday, when a successor to the FS100 comes out that is cheaper (and smaller, as I do a lot of outdoor run-and-gun), I can leverage those lenses. One thing I want to do is night time-lapse – for that I would buy a specialized wide-angle, large aperture lens with great light-gathering power.

    I had heard bad things about the Sony “E” lenses – which lens do you have on the FS100?

    Thanks,

    Steve

    Glyn, one caution about that FS100 with the stock 28-300mm zoom. That lens is no faster than 3.5 at wide, so I’m not sure how good it will be in low light. Of course, you could always buy another monster, expensive lens with a huge eyeball – I was looking at some Fuji’s in the $6K range … 😉

    Hi there,

    I think your suggestion is a good idea as lenses last forever. I had heard nasty stories about the stock lens and I do understand the limitations of the low light and slow focus. However as far as detail it far surpasses the NX5U in great detail and color. With the NX5U and various profile tweaks I can create some rather nasty saturation issues on the FS100 it does a superb job. Also the stock lens supports auto focus, iris and gain. Well most E-Mount lenses should. The sensor is the same as the Sony F3 which is also fantastic but of course has the $13,000 price tag.

    Anyhow back to topic. Like I said lenses last forever and I believe this is where video is moving as it just gives you so much flexibility in a variety of projects. I have not invested in the FS100 as I have only used it a couple of times now. The plus is that the workflow will be the same as the NX5U, yet another plus.

    What troubles me about the NX5U or it may just be my model is that even dead center there is a small amount of CA.

    More than happy to share any more info with you. I have played with it quite a bit and I think it is an awesome camera except for the CA issues which unless you are on high contrast areas you would probably never see it 🙁

    John, don’t get an NX70! All three that I “owned” had the same horrible problems. It is just a CX700 gussied up with more manual controls and the waterproofing.

    I’m so relieved that B&H allowed me to return it.

    I just ordered an NX5U – will be here next week. Biting my nails. Wish me luck, everyone!
