Re: Canon USA reveals EOS 5D Mk. IV with 4K, new L-Series Lenses
 

Coming from the Mark II, I have no doubt that the improvement will be significant for me. A lot happens in eight years!

Oh yeah, the new iPhone 7 will be announced on Sept 7th. My iPhone 5 has one broken microphone, the screen is popping out on one side, and the memory is full. I've been putting off replacing it to be on the favorable side of the upgrade cycle, but it's yet one more purchase that delays my DSLR upgrade. Oh well. 1st world problems...

Personally, I've never cared for peaking. (I'm not saying it's bad; it's just not my preference.) I've used it in my son's Shogun, but it always seems a bit eager to say that things are in focus. Maybe I need to look more at the peaking in front of and behind the subject, rather than at the subject itself.

That said, a flat profile and more bits is the thing I most want, but isn't in the spec. I believe that one can dial in a flat profile (is Technicolor's CineStyle still available?), but it won't be exactly Clog. I don't need Clog as I'm not matching other cams, but I can appreciate that if I had a Cinema EOS camera, I'd strongly want Clog in my b-cam too.

Speaking of the Shogun, I wonder how well this will work with the 5D4?

I expect that the HDMI will have a clean video output, given that this is true on the 5D3 and its competitors.

The open question is about resolution and sharpness. When shooting full frame, DSLRs depend on line skipping or filtering on the sensor in order to reduce the data rate from the device. The 5D3 video is soft. Will full-frame HD on the 5D4 be sharper? We will see...

And then there's windowed 4K. When shooting in this mode, the HDMI output is HD. I wonder if the downsampling is good? The nice thing is that all of the 4K data is available to the Digic chip without pixel skipping. It's possible that the Digic downsampler will have high quality, and then the Shogun can provide peaking and a variety of recording formats to SSD. Yes, it's extra kit, but it would make the camera quite useful for bigger projects.

Having worked with different brand camera's the implementation of peaking can be very different, from unreliable and difficult to judge to very accurate, my jvc ls300, eventhough it has not good a good quality lcd, has the best and most accurate peaking of any camera I ever had, this combined with magnified focus while recording has become a critical function for all my shoots when it comes to guaranteeing it's in focus. I think if you say you don't care about peaking is because you never had a camera that has good peaking, especially with full frame camera's peaking/magnified focus is not a luxury as how good a autofocus system can be, in most situations you want to be able to check up and finetune if needed, having no peaking and no magnification during recording is not very reassuring.

Thanks, Noa. I've played around with a few cameras with peaking at trade shows, and each time I felt that I could do better by eye and that the peaking actually obscured the details that I wanted in focus. Good to hear that some implementations are better than those I've seen.

Still, I'm wondering if looking for peaking just in front of and behind the subject might be a good technique. Not all compositions provide the right context, but when they do, one could confirm that the subject is in the middle of the focus band.

Then again, if DPAF works as well as I've read, this might be somewhat moot. For solo shooting, DPAF would be my go-to solution. For team shooting (though it's been a while), we do the traditional 1st AC / follow focus thing. In that case, the focus puller doesn't look at a monitor. It is, however, important that the camera op be able to see when focus is "buzzed."

One thought on this: for team shoots, maybe it's even better if the camera op sees the full picture for framing only and if an additional person has a larger or zoomed monitor and watches for buzzed focus only. It's always best when each person can focus on a single task.

In other Canon news (not related to the 5D4), Canon has developed a global shutter sensor.

For 5D4 performance, the 8-bit limit is a disappointment. The remaining big questions are low-light sensitivity and rolling shutter. Canon's announcement of a global shutter sensor might be another key step in moving to mirrorless cameras. Combine a fast, global electronic shutter with improved DPAF-style focus and the mirror will no longer be necessary. That makes cameras smaller, more robust, and cheaper to produce. Canon executives have previously stated that they don't plan a high-end mirrorless camera because they don't believe that the performance is quite there yet. (Keyword: "yet.")

Hey Chris! My 5D mk4 arrived!

Here's my official DVinfo article:
It takes a good picture. It only comes in black.
