Odp: Czy we wszystkich bezlusterkowcach ciężko ustawić autofocus
zamieszczam wyjaśnienie dlaczego canon to najgorszy system do nagrywania video:
Video Specialist Andrew Reid from EOSHD:
"the sensor isn’t so much to blame as Canon’s image processor. In the stock Canon video mode it is as if the sensor is doing a nice output, but the processor is resampling the image to purposefully hobble it with moire and soft detail" - czyli to co masz na wykresie, zostaje wykastrowane! i dlatego powyższy wykres nie jest prawdziwy dla video
i dalej:
"But as if holding features and crippling image quality were not enough, Canon decided to take a step backwards with the new 6D Mark II. The video All-I mode has been removed, leaving us with lower video bitrate compared to original 6D.
When it comes to 4K, the new 6D skipped it entirely. Sure, the 5D Mark IV has 4K, but with a 1.74x crop and completely huge and inefficient 500 Mbps MJPEG codec from the 90s, the 4K mode is just unusable."

Video Wreck
On the video side, the situation is even worse. After creating the DSLR video revolution back in 2008 with the 5D Mark II, Canon constantly crippled its DSLR. Basic video features like peaking and zebra never made it to any DSLR of the brand. The 60fps mode was sadly missing on the 5D Mark III. Was it a hardware limitation? Absolutely not, the Magic Lantern team demonstrated that the Mark III was capable of 1080/60 in raw recording and gave us all the video assist features via their firmware hack.
Another issue that consistently plagues Canon bodies is the image softness and moire. Video Specialist Andrew Reid from EOSHD noted about the Canon 100D/SL1 magic lantern hack: “Forgive the conspiracy theory, but I thought moire was a result of pixel binning on the sensor itself. But now we have unfiltered direct access to the sensor output in video mode with raw, it seems the sensor isn’t so much to blame as Canon’s image processor. In the stock Canon video mode it is as if the sensor is doing a nice output, but the processor is resampling the image to purposefully hobble it with moire and soft detail.”

Want to film in 4K at 24mm equivalent? You’ll have to attach a 14mm lens to your camera. And by the way, be ready to buy a substantial amount of memory cards because at this rate, a 128 GB card will be full after only 30 minutes of recording. I hope you like to transcode. But for real, the Dual Pixel Autofocus is great.
Perhaps remorse struck Canon a few month later when it decided to issue an update to enable the LOG mode on the 5D Mark IV. However, LOG is not available at this time on the top-of-the-line Canon 1Dx Mark II. I’m sure that loyal Canon customers will appreciate being left behind after spending $6,000 on this professional body while cheaper versions are being upgraded.
“Why don’t you buy a damn video camera?”; “DSLR are not made for video.”; These are usually the kinds of comments we get when we dare asking for decent video features on Canon professional cameras in 2017. Let me answer: No, I do not want to buy a damn video camera. The reason is not due to the hefty price tag, but due to portability and versatility. Even if the C200 was available at $900, I would not buy it. Video cameras are big and bulky, and I cannot afford to carry a C100 Mark II that weighs twice as much as my current 5D. As a run-and-gun shooter I want to take photos and videos and be able to switch conveniently between the two. Another point is that professional cameras are fitted with S35 sensor giving a 1.5x crop factor. But I like to maintain the full frame look and non-cropped focal range of my DSLR.
By the way, DSLR can and has been used for video for years now, even in Hollywood movies. We are not asking for extravagant video features in DSLR. Built-in ND filters, XLR connectors, ultra-high frame rate, and uncompressed output are reserved for professional cameras and we know it. What we want is decent video specifications contemporary of the era with reasonable image quality. If the 5D came without 4K crop, clean 8-bit video, and codec from this decade I would have bought two already.
