I know this is a bit of an old thread at this point, but let me share my story that I think is quite relevant, and that can hopefully help out others.
I am now on my 5th (that's right, 5th) Mavic unit. 3 of the 5 units I've tried had a blurry right side. 1 of the 5 I never checked because it had physical damage out of the box. The only one that was sharp across the frame had to be replaced for another unrelated problem. So, 3 of the 4 units I've tested for this problem had a blurry right side.
Of note is the fact that the 3 affected ones had the blurriness to varying extents. One of the 3 was extremely blurry (totally unacceptable for me), while the other 2 were definitely noticeable, but not absolutely horrible.
What I've noticed on this most recent unit I'm testing now is that, as you rack the focus, you can clearly see the focal plane is kind of lopsided (it looks like a rectangle that is tilted away from the camera on one side), and the difference in focus between the two sides becomes much more apparent the closer to the camera the focus is set at. It's less apparent across the entire image when you're focused on more distant objects.
I've drawn a few conclusions from my experience so far:
1. This clearly seems to be a hardware problem, in my opinion.
2. What are the chances that 3/4 units would all have this defect, unless it's not really a "defect", but rather a "feature" of the Mavic that falls within the acceptable QC specs. This sucks, and is hugely irresponsible of DJI, but it also suggests that the chances of receiving a Mavic that is sharp across the frame are very low (how can I be SO incredibly unlucky???).
3. A workaround may be to adjust where in the scene you focus. For example, I've been able to get footage that is pretty sharp across the frame if I focus further away than I think I need to. I need to do more testing, but I think there may a sweet spot where the foreground, background, left side and right side are all sufficiently in focus. This may not help for cases where your subject is quite close to the camera, but will hopefully work in most landscape situations.
4. It's been 6 months since I first paid for the Mavic. I got my first unit in early Dec. (about 1.5 months after I was supposed to), and have only just recently received the 5th unit. In other words, I have now spent 4 months going through exchange after exchange, continuously asking DJI to make sure the replacement they were sending did not have the focus issue. They have repeatedly failed. I do not want to wait AT LEAST another 3-5 weeks to be able to use this thing. I've already missed almost the whole winter where I am, which is one of the main reasons I wanted the Mavic in the first place (to get snowy mountain footage). The unit I have now appears to be able to give me good, sharp footage at least sometimes, so I'm hoping I can make it work by using the workaround I described above. Maybe one day, when I'm not so desperate to use the Mavic, I'll send it in to DJI for a proper repair (I do have DJI Care). But right now, I'm simply not willing to deal with this anymore - it's just been far too frustrating.
So anyways, to those thinking of sending their Mavic in for replacement because of this issue, I would think hard about just how bad the problem really is on your unit, because the chances of getting a truly good one are quite slim in my experience, and you'll be without a Mavic for a good chunk of time. |
