7DII and landscape photography

[tinwhistle]

I'm thinking of updating to the 7DII. In the course of on line research I've seen it mentioned that this camera excells at most everythinmg except landscapes. Anyone out there have this experience?? Thanks for any input...

The other reason why the 7DII is not considered as a great scenic camera (despite it's outstanding AF capability) and that nobody has mentionned yet in this thread, is that its Canon APS-C sensor has a slightly less dynamic range from ISO100 to ISO400 than latest Sony APS-C sensors used in other DSLR camera manufacturers.

This means that the camera will capture a smaller range of tones by shot and will have more tendency to underexpose or overexpose from ISO100 to ISO400.

Personally, this is not very relevant to me as a sport shooter (there are other important factors on image quality and camera capabilities), but many experts mentions this weakness found on APS-C DSLR Canon cameras.

Yes, but same dynamic range as 1DX has at ISO 100, 11,8 EVs (dxomark.com).

And about the older 7D, take a look at the sky and the pattern. Above ISO 800 and it is not visible anymore.

[Ricci]

OK, but other DSLR's are well over 14 Evs!

I know that the 7DM2 has improved over 7D in terms of noise but unfortunately not much in the dynamic range area.

[Peter]

Correct. Canon is not at the top. 5Ds 12.4 EVs, 6D 12.1 EVs. You need to shoot dual ISO to get the same dynamic range as Sony sensor has.

[Ricci]

Yes, but you will also gain moiré and aliasing using dual ISO mode.

I hate to confess this, especially since I've been "taking pictures" for about 60 years and even been paid to take some, but I have no idea of what the following statements mean: dual ISO, dynamic range, moire, aliasing.

Correct ricci. What you gain in something you loose in something else. You will also loose resolution in the highlight/shadows.

Tinwhistle:

Dual ISO is two at the same time. Dynamic range is how much your camera can pick up before it clips the highlight or the shadows. You can make a image search at moire and aliasing to see how that looks like.

Examples of dual ISO you will find here

7898.CR2 has ISO 200.
7899.DNG har ISO 100/200. Take a look at the highlight between 7898 and 7899 and also keep your eyes on the roof and aliasing.

9398.CR2 has ISO 400.
9399.DNG has ISO 100/400.

9402.DNG has ISO 100/800.

Canon 7DII can´t shoot dual ISO.

Does any Canon camera have that capability? My 5D Mark III manual doesn't mention it. Despite being about Tinwhistle's age, and despite having owned several Canon DSLRs over the past nine years, I'd never heard of dual ISO either.

Dual ISO is included in Magic Lantern and if you fail with it Canon guarantee will not help you.

Thanks for the clarification. I can't imagine that I'd ever use Magic Lantern, but out of curiosity: If ML starts causing problems, or if you change your mind, is it possible to restore the Canon firmware? Or is that a one-way street?
