Canon 5D Mark IV -- Time to Discuss!

Sad how we cannot project even the resolution of the Canon 20D without spending $10000

Video is dominating by the broadcasting. all broadcast right now is 720P which is why services like direct tv/dish etc are only 1080i because after the signal is transmitted it's upconverted. Broadcasting is having a hard time figuring out 4k.

Not sure why some people here have this shup up and love it mentality..
Im sure its a brilliant camera .. but it does have its flaws..as it has its positives..

I dont know why discussing its flaws is consider4d crying

Well.. anyway different strokes for different folks.. as they say..


Still on the fence on preordering

Early adopters pay the price.

ya to get to use the camera 3-4 months earlier than anyone else. Damn right it's pay the price.

To be fair, canons were bashed on DR (I didn't ever bash canon on this, chalked it up to lack of tech).

There are many feature withholding tactics canon does that drives me nuts, this would be one of them.

When we all get 4K (TV, DVD players, monitors) then here comes 8K, and we start all over again.

Watched the Rudy Winston video. Lot of cool stuff beyond the specs. I think I'll still wait for the 6D2 and see what features from the 5D4 and for that matter the 80D too transfer over.

When my older brother (the photography professor) bought a laserdisc for himself many years ago, I thought he was nuts. But the quality of the images was really great. The movies that came in that format cost more than 4 people going to see a movie now. So, it was a very expensive investment. He kept it for a long time. I preferred to wait. Now everything is streamed so not even needing the DVD anymore, I feel the 4K thing is only good when I can actually sit down in my theater room to watch something. Most people now watch movies on their mobile devices. I guess I can watch my Netflix on my 4K 15 inch laptop, but it doesn't stream 4K, yet. I don't think I want to ditch my wide screen yet, even if it isn't 4K. But maybe, if the price is much lower, I can change my mind.

I think just having the choice to shoot for 4K or not is what Canon wanted to give. For those of us who mainly shoot stills, events, sports, etc., the video capabilities may be used, perhaps not. I think what makes the video so attractive is that some kid, like my 17 year old, will take the time to watch the endless videos on how to make the 4K shooting great and actually do it.

I just read 4 articles about the benefits of mirrorless cameras versus the "old" DSLR's. An author even suggested we ditch the DSLR's and go for mirrorless as it is the "newer" way to go. I've been shooting SLR and DSLR's for 25 years and I don't think I'm jumping ship just yet. Canon and N*kon are slowly losing their grip on the market because of the new technologies and all the other brands that are producing smaller cameras that may have the same quality images. But really. When I get my hands on my 5D4, just trying convincing me that it's not the best camera ever! Canon's got my money. I'm too old to do more than upgrade. Cheers! Have a great Friday.

8K is already here. Our local big box electronics store had 8k display and I got to say that the picture was so sharp that it looked wrong. There was just too much detail.

What is the point of diminishing return? At 6 meters or 20 feet, a human eye with 20/20 performance is able to separate contours that are approximately 1.75 mm apart.

So if we interpolate, 1.75mm at 20' is 0.875mm at 10', is 0.438mm at 5'...our eye will SEE the pixel only when it is larger than (rounded) 0.44mm when viewed at 5' away.
With 4K TV that is 60" in horizontal size, the pixel pitch is 0.372 apart. But remember, we are VIEWING at 60" (horizontal) monitor from 60" away, which is closer than the suggested 1.5 * diagonal viewing distance suggested (screen diagonal = 68") . Yet even with a 4K screen viewed from a close 60" it has a pixel pitch (0.372mm) which is smaller than our eyes can detect...an online calculator program for screen size

says that with 4K screens you need to sit 4' away or closer simply to 'see all the detail'. 8K for home viewing is pointless.

For the monster cinema screens, 8K is necessary because the 4K screens show us pixels which are visible in the forward areas of the seating.
The optimal viewing distance for a 50' diagonal 'standard house' cinema screen is said to be 19', the pixel pitch is 1.7mm on that 45' wide screen, so we can sit as close as 20' and not see each pixel on the 8K screen.

I had already figured in the calcs you have above for 4K and based on the size of our room and the fact the the wife doesn't want an over bearing sized TV, 4K is pointless for me much less 8K

The other issue with streaming 4K is most bitrate is like some 15-20mbps while the actual 4k bluray discs will do 110mb something like that. Much better.

1080P bluray disc will look better than a streamed 4k any day of the week WHEN you have 100+ inches of screen and a viewing distance of 12-16'. 1080p discs average 35-45mbps of video output.

4K is here... but it has a very long way to go before becoming mainstream and we are talking it'll be 10yrs down the road.

12' away from 135" and I'm suppose to have 4k but 1080P looks great. Thats been my point... ya it could be a major impact but for me... I know I'm not adapting 4k for some time.

I have a built in cabinet and I am limited to 50" unless I do cabinetry work and that has been vetoed by the wife not wanting anything bigger.

For me as well. My wife thinks something larger than 40" diagonal is a bit overbearing. It would need to be a drop-down projector screen from the ceiling, so it is not so ugly, for me to get something larger! 2K for me.
