1dx mkii

[Kayaker72]

I have one of the first 1DX MKII that arrived in May 2016, I have been very impressed with the handling and auto focus it was primarily purchased for wildlife photography. My only gripe is that above 1000 ISO it is very noisy, I have updated the firmware but it really is no better than a 5D MKIII. I would be interested if anyone else has any views or opinions.

First of all, welcome to the forum!

I do not own a 1DX II. A few members of the forum do, and perhaps they will chime in.

What I can do is look at different tests, but also, my general understanding is that sensor improvements from the 5D3/1DX to the 5D4/1DXII were more in the base ISO range. Not necessarily >ISO 1000

Starting off with TDP, I would say the 1DX II has just a very slight advantage at ISO 3200. Really, it is just a finer grain of noise.

Then, over at DXOMark, the signal to noise ratio is almost identical (look under measurements). Really, the only difference they show is in DR and color sensitivity

Then, on Photons to Photos, they do show a significant difference in read noise:

Having owned the 5DIII and 5DIV, I do think there is an advantage, but it really isn't as much as some internet forums would have you believe. So, you may not be mistaken. There is a slight advantage for the 1DXII, but it likely would take certain circumstances and a trained eye to see it.
