DJI Mavic 4 Pro – 根本是必備品！！！ (DJI Mavic 4 Pro - IT's A MUST HAVE!!!!)
- Yes, but it's a combination of this using the technology that they already have they already know how to tilt the gimbal on the mini four pro so it's not something new they're doing yes it's a newer gimbal it's a bigger gimbal but they already know what to do they've been there they've done that with the mini four pro the 360 obstacle avoidance the LIDAR this particular type of body shape or concept they've been there they've done that they know what works so when you think about it even though the Mavic four pro is a new drone it's not really it's a combination of the mini four pro and the Mavic three pro they took those two technologies that they have and a little bit from the air three s combined it all and made a new drone so I'm not really worried about unfinished software and a whole bunch of bugs and kinks now he's been there and done that yes have they improved the cameras a little bit adding 6k which I really want that's the other reason I want it everyone who knows me know I'm a big 6k fan that's the reason I didn't buy the air 3s because the air 2s had 6k and I absolutely loved it and he took it out of the air 3s so I just I stayed away from that drone so yeah I believe it's safe to pick that drone up from day one and I think you should go ahead and pick it up too if you can afford it and if it's something that you want because let's face it it's not something that we need but if it's something that you want yes and you it's not gonna break the bank go ahead and pick it up especially with that new controller I have to get that new controller I love a big screen in my life do I need it no I've got a big screen on what I fly right now and it's pretty fast to set up but I just I really like the controller so I'm gonna get it anyway plus the controller supposed to be compatible with the older drones like the air 3 and the mini 4 Pro and the air 3s so that I'm looking forward to as well so yeah that's the main reason why I am getting the Mavic 4 Pro I feel like it's a no brainer it's not something completely new that DJI has brought out that has never been seen before and as a result it's not brand new brand new technology that we should be worried about but it is a step up compared to the Mavic 3 Pro and I think if you can afford it yeah you can get it because it takes the best of all the other drones that have been released before and combines it all now let's talk about the reason why I'm keeping this drone the Mavic 3 classic and why I sold my Mavic 3 Pro I sold the Mavic 3 Pro because the Mavic 4 Pro cameras are going to be better they're going to let more light in they're going to be better in low light they have slightly bigger sensors and once you get used to the that camera spec and you start getting used to shooting 6k or or or just better cameras it's hard to go back and so I know myself I'll never end up flying my Mavic 3 Pro once I have a Mavic 4 Pro so what's the point just get rid of the Mavic 3 Pro I don't need it and yeah I know people say backups I have a backup right here that's good enough if client work needs to be done but that's not the main reason why I'm keeping this the main reason why I'm keeping this drone is because this 20 megapixel four third sensor is tried tested and proven you look at this mini sensor this is a one over 1.3 sensor that's actually a 50 megapixel camera 50 megapixels so what DJI actually did is what's called pixel binning and people think that this is a 12 megapixel camera that's turned into a 50 megapixel camera but it's not it's a 50 megapixel cameras there is 50 million pixels on that sensor that is sensing light what pixel binning actually does is take groups of four pixels that will sense four different colors and actually make all four of those sense one color essentially turning four different pixels pixels that sense four different colors into group them to make them into one giant pixel to sense one color so you can actually tell the pixels or group the pixels to sense colors that are the same so that's pretty cool I made a video here explaining it on the mini 4 Pro and the same concept will apply to the Mavic 4 Pro that's going to be effective 100 megapixels that will group the pixels into four four different colors group them in those four different colors group them into one and make those four different colors actually sense one color turning those four pixels essentially into one giant pixel that's all it's doing and that's how you take 100 megapixels you group them into groups of four sensing the same color and essentially you'll have 25 megapixels and that's what the 100 megapixel camera the four thirds camera on the Mavic 4 Pro will be doing and I'm just not sure that the results will be as good as this 20 megapixel camera at least when it comes to photography video might be harder to sense when the pixels are grouped but for photography this might actually be a slightly better camera and I'm not sure until I test it so that's the reason why I'm hanging on to this so make sure you subscribe if you want to see me put the new four thirds sensor against the old one the 100 megapixel versus the 20 megapixels now not saying that the 25 or the 100 megapixel camera four thirds camera is not going to be good on the Mavic 4 Pro it has a faster aperture this is an F 2.8 that one is an F 2 so it is going to let more light in which is key which you need when you have a lot of megapixels so you know DJI does know their stuff and they know how to cover up and blend and use software to fix things internally within their drones they have a lot of experience and a lot of good technicians working for them so chances are the Mavic 4 Pro might all round be a better camera compared to the old four third sensor on the Mavic 3 Pro but tomorrow's right around the corner the drone will be released I will put my hands on it as soon as it is released I will be placing my order because I am dying to test these cameras and see which of the two perform better under what circumstances so with that being said let me know in the comment section below are you buying the Mavic 4 Pro as soon as it launch are you worried about bugs and kinks and stuff like that or you just don't need it or maybe you're just not interested whatever it is let me know in the comment section below I will see you guys tomorrow after the launch date because this is supposed to be one exciting launch we don't get Mavic Mavic 3 Pros and Mavic 4 Pros and Mavic 5 Pros every day it's roughly every three years so to this it's probably another couple of years before you see the Mavic 5 Pro I'm going to get on it let me know if you're getting on it and make sure you hit subscribe make sure you check out this video that shows you how you can get a 50 megapixel camera down to a 12 megapixel and so you can understand pixel binning and how that works and I will see you guys well in the Mavic 4 Pro video.
是的他們已經知道如何傾斜迷你 4 Pro 上的雲臺，所以這不是他們正在做的新東西，是的，這是一個更新的雲臺，是一個更大的雲臺，但他們已經知道該怎麼做了。所以仔細想想，儘管 Mavic 4 pro 是一款全新的無人機，但它其實並不是，它是迷你 4 pro 和 Mavic 3 pro 的結合體。是的，他們對相機進行了一些改進，增加了我非常想要的 6k，這也是我想要它的另一個原因，認識我的人都知道我是個 6k 大粉絲，這也是我沒買 Air 3s 的原因，因為 Air 2s 有 6k，我非常喜歡，但他把它從 Ai

鏡頭光暈到底是什麼？！ (But What IS A Lens Flare?)
- Every single lens element, including the aperture, will in principle incorrectly reflect or scatter or diffract a small amount of all the light that hits it, and that light then bounces around in the lens before hitting the inside wall of the lens or going back out the front, or hitting the image sensor.
包括光圈在內的每一個鏡頭元件，原則上都會錯誤地反射、散射或衍射一小部分射入鏡頭的光線，這些光線會在鏡頭中反彈，然後射入鏡頭內壁或從鏡頭前端返回，或射入影像傳感器。
- Every single lens element, including the aperture, will in principle incorrectly reflect or scatter or diffract a small amount of all the light that hits it,
例如，如果 99% 的光線正確通過鏡頭元件，而只有 1% 的光線反彈並導致鏡頭耀斑，那麼耀斑的亮度最多隻有正確光線的 1%，您可能不會在最終影像中注意到它。
