Canon 5D Mark IV -- Time to Discuss!

Time for an exchange from the original place of purchase.

I strongly doubt I'll have any problems getting that done (the vendor I used does seem to have good customer service), but, you are obviously then just pulling the gamble handle on what turns up (i.e. whatever the manufacturing tolerances are for the bodies).

I think it was the right thing to send it to the service centre (prior experience of their work lead me to hope it'd some back bang on the money; so arguably better than off the factory line), but obviously that hasn't working in this instance.

I'll want and see what the service centre respond with.

I would think sending it in would work best too. Soooo, Canon says it's within tolerances? Tell them to try again.

Clear as mud.

Glad I asked

Maybe if someone has both, if they can be bothered, try both and and report back with the vibe.

I would be happy with the Vibe.

Ok, here's the vibe. I used my wife's 70D, but the 7D2 is just an enhanced version of the same sensor.

70D + 100-400 II full resolution: 5472x3648
5D4 + 1.4x III + 100-400 II full resolution: 6720x4480
5D4 + 1.4x III + 100-400 II cropped to 70D: 5850x3900

So the 5D4 with the 1.4x puts more "pixels on target" than the 70D (or 7D2) without using the extender.

70D + 100-400 II @ 400:

It seems to me that the 5D4 + tc shot is resolving more detail. Thanks for doing the test and sharing

Ok but how often when shooting wild life are you actually able to frame what you need on the crop with out an extender? Usually people have to use crop, an extender, and then crop more. So how about a test with the 70D using the 1.4 TC (a 7D2 or 80D would still have AF) at 400mm and then crop the center 50% from that. Then take the picture with the 5d4 from the same position with the same TC plus lens, and then crop the FF image to match the framing of the crop image.

That comparison above I think is the best case scenario for the 70D. Adding a TC and cropping on the 70D and comparing to a cropped 5D4 image I think would make the 5D4 look even better

I'm with FEC. When I am birding, I have my 7D2 with a 500mm and a 1.4X. That's my baseline. If I move to a 5D4, then, all else being equal, I will be putting FAR fewer pixels on the bird. Only by using a 5DsR and cropping by 1.6X or so do I get anything in the range of the 7D2 as far as pixels on bird are concerned.

Bottom line is - going from crop to FF is a losing proposition for pixels on subject unless you move to a 5Ds(R).

Ok, so what I have worked out is this:

The screen that they show on page 88 is actually the info screen. If you press the [Info] button a few times you will come to that screen. The [Q] icon in the bottom left corner is the only touchscreen enabled button on that screen which, after pressing, will take you to the Quick Control Screen where all shooting options can be changed on the touchscreen.

Mike, thank you very much!

Not to mention you lose half your FPS going to the 5Dsr. If you compare to the 80D, you don't gain as much FPS but you also gain the 4mpixs.

I'm just jealous....

my 5D4 takes way better photos then I could ever take.

70D + 100-400 II @ 400:

5D4 + 1.4x III + 100-400 II @ 560 full shot:

5D4 + 1.4x III + 100-400 II @ 560 cropped to 70D photo:

Thanks for doing that, Iwill have a close look after work and try and absorb the information.

Really? Where. Looks identical to me.

In the grain of the palings on the left for example, but also just in general. It's only by a small amount though.

IMHO, the 5D4 still wins if 2100x1400 is enough pixels versus 2700x1800.

70D + 1.4x III + 100-400 II @ 560 (live view focusing) 2732x1824 crop:

Again, still gaining the IV's trust before I bring it onto any soft of paying gig. I've been walking around, really testing its limits. While nothing special about the subject, and slightly over processed, this shows off the nice shadow recovery. I've also attached a bottom, left corner at 100%. Pretty good detail detained. I've only attached screengrabs since it's easier. Ha. This was 35L II, ISO 500, f4.5, 1/160.
