dslr body with best dynamic range?

Hi all,

 

  I'll admit I keep thinking the mpx has something to do with the dynamic range of the body itself, but i keep forgetting it's the sensor that has to do with it. Idk anything about the sensors, I purchased my A7ii solely off the fact my friend (who's a very talented photographer) sold his Canon 70D and got an A7ii and recommended the body to me. My question being, say if I were to shoot with the Zeiss 55 1.8 (the closest sony native lens I have w/o usage of an adapter), which body would I get the best dynamic range with in general, if it were between A7ii, A7s, and A7r? I very rarely crop my photos so in a sense, I guess I could say MPX doesn't matter to much to me, I care more about shadow and highlight detail recovery more than anything else. TIA!

Re: dslr body with best dynamic range?

DxOMark.com publishes the results of objective tests performed on cameras, including tests for dynamic range.

 

Of the bodies you mentioned, the A7 II, the A7S and the A7R, they all have about the same DR until the ISO is set at about 3200 or higher, when the A7S outperforms the others. See https://www.dxomark.com/Cameras/Compare/Side-by-side/Sony-A7-II-versus-Sony-A7S-versus-Sony-A7R___99...

 

Click on the Measurements tab, then Dynamic Range.

 

If you compare the A7 II with the A7R II and the A7S II, the A7 II falls short of the other two, but again, only when the ISO is at 3200 or higher. See https://www.dxomark.com/Cameras/Compare/Side-by-side/Sony-A7S-II-versus-Sony-A7R-II-versus-Sony-A7-I...

 

So with a large aperture lens in regular shooting conditions, there's not much difference.

Re: dslr body with best dynamic range?

To me, this is interesting because when I'm shooting at >400ISO sometimes, the shadows are barely fluctuating in post. That being said, does shooting with FE and E mount lenses have a big difference when it comes to DR as well? I'm about to shoot with the 55-210 along with my Zeiss 55mm tomorrow and i'm not sure how well my 55-210 will work out on my A7ii. I'd use my 55mm but I really want the focal compression of the 55-210Smiley LOL this is just temporary though, as I'm trying to find a used Canon 70-200 F4 in my area so I'm using the 55-210 for the time being.

Re: dslr body with best dynamic range?

The choice of lens shouldn't affect the dynamic range of the recorded images or movies.

 

What may have an effect is the use of an APS-C lens on a 'Full Frame' body, though. Sony's 'E' lenses project a smaller image, appropriate for an APS-C size image sensor, while the 'FE' lenses project larger inages suitable for 'Full Frame' cameras like your A7 II. For still images, that means the A7 II will only record a 10MP image when an 'E' lens is attached, instead of the native 24MP when using an 'FE' lens. I'm not sure how using an 'E' lens when recording movies will affect the results, but certainly, using a smaller imaging area wouldn't produce results as good as an 'FE' lens using hte entire image sensor.
