    Well, I’ve found auto focus to work really well when tracking motion shots such as shooting football games. The issue is when the subject you want in focus is drastically offset to the right or left of center. Keep it near the middle and you should not have a problem. I actually shoot football most of the time in manual focus and have no problems keeping focus. The LCD is really good and the focus ring response is very precise.

    Thanks, everyone.

    Now I’m even more worried. Back focus is one thing, it can be compensated with auto-focus.

    But the mention of inconsistent focus across the image is horrifying, and is one of the two problems with the NX70 that is the cause for rejection. My CX550V does NOT have that problem.

    The other problem is the horrible chromatic aberration at zoom.

    I’ve put a few more examples of the problem here – look at the ones from Dec 19, please. Anyone seeing this with the NX5? You will need to shoot something against a bright background, typically sky.

    I really appreciate the feedback. John, some frame grabs would be great – I would imagine that you have plenty of wedding shots at zoom with bright backgrounds.

    The leap from $2.5K for the NX70 to $4K+ for the NX5 is scary, and I will also lose the 1080 60p …

    Here are some frame grabs from soccer games.
    I chose ones that are shot against the sun, and have some sky in them.

    They were shot in 1920x 1080 x 60i. ND1 filter on. Approximately 1/180th of a second. Aprox 5.6 f stop, -3db gain.

    I hope this is helpful to you.

    John, I truly appreciate your taking the time to post these shots. I am studying them closely. Although I see some CA (green edge on the light pole), it seems far, far less that what I experience with either the NX70 or the CX550V.

    Question: what was the zoom setting? Any of these at 20x?

    I’m adding more shots of CA to – latest will be uploaded in about an hour; a jet landing at sunset with the sky behind it.

    The zoom on these various from about 10 to 100%. You will have to guess based on me standing next to a soccer field midfield line.

    Someone on this forum earlier did a study of outdoor shots with the nx5U and determined that the chromatic aberation was best if the lens aperature was opened more than 5.6 and worse as it got toward f11.

    I thought I would jump in here as I have been doing a load of searching to see if other videographers with the NX5U had experienced CA (chromatic aberration). I was blown away by how strong the CA is on my NX5U which was only bought 3 months ago. My tests are all based off subjects on clean white backdrops at full wide zoom 0/100, f2.6, -3db. The CA is present ever so slightly in the center and is rather strong as you move mid way and even worse closer to the edges. Up until this new camera I had been using my trusty Sony FX1 and never saw this (although when I look back it is there but only slightly). I understand the NX5U is of greater quality in many factors than the FX1 but the CA was something I had not seen up until now.

    Having all this footage I decided to contact Sony to see what they thought. Their response was not what I had expected, 2 specialists said this is to be expected from a cheap lens. They did say however to take it in to be checked as well. I will be doing that this week. I will give you an update later.

    So from my experience and research the quality of the glass is the issue here and with having a fixed lens there is not much else you can do.

    I have seen you images and I could safely say that the NX5U would probably produce the same CA.

    I changed jobs in March and want to upgrade to HD here at my new job – reading these reviews leads me to believe that I want to migrate to XDCAM EX cameras like I did my last facility, and skip NXCAM entirely. I appreciate the sample images and diligent reviews.

    This is similarly worrying and reassuring. I am seriously looking at the NX70 for ski videos due to its water resistant capabilities, but after reading some of the posts here I’m worried the quality & problems may be less than I expect from a professional camcorder.

    Having used Z1s and EX3s extensively, will I be sorely disappointed by CA and zoom/focus problems form an NX70? Has anyone had similar experiences with a PAL NX70E?

    Thanks in advance! John

    Hi Glyn;

    Sorry it took me so long to respond.

    I really appreciate your feedback on this. I had been seriously considering the NX5, but now I’m not so sure.

    Do you have any samples you can provide?

    I’ve posted more samples of problems with the NX70, even worse than the CA is persistent bad focus on the left side of the image – this is not CA, it is something else.

    Thanks again,

    Hi there,

    No problems on the slow response my main concern was to get as much info to you as possible seeing as I had already made the purchase. To give you a quick update I actually took the unit in to Sony for a checkup and the focus thing you talk about on the left hand side was actually present too so they ended up replacing the lens to resolve the soft focus on the left and also to realign. The sad news is, that after Sony having the unit for 3 weeks the chromatic aberration is still no better 🙁

    Follow this link to see some examples where it is quite terrible in my eyes:

    I will only keep this page for a limited time so you can see the issues I have had.
