Analysis of RAW samples at Fred Miranda show weak DR

[Adelino]

I really hope production models show different results but things do not look good. http://www.fredmiranda.com/forum/topic/1497323/25#14098826

Wonder how many pre orders are being cancelled over it.

I wonder how many people realize that you need to have a picture of a high DR scene to analyze the sensor for DR?

You can't use just any image......

How about 15 minutes over sunset, camera straight into the sun, over glimmering sea without CPol and some jet black rocks in the foreground should qualify, right?

Sekonic DTS software analyse 3 (three) photo (in RAWformat) of the X-Rite Colour Checker Card at -3EV, 0EV, +3EV in order to determine dynamic range of the camera and taken at a particular ISO. There is obviously a reason why it takes 3 images for proper analysis and why it has to be photo of a specific colour card.

This is a very interesting post. I've been following lots of 6D Mark II discussion and this is a real shocker.

There have been enough raw images from the 6D Mark II posted for someone to graph its entire ISO range. At ISO < 800, the 6D Mark II delivers lower results than the 6D. At ISOs over 800, the 6D Mark II is better by less than half a stop than the 6D. At ISO > 3200, it's similar to the 1DX Mark II:

What's Canon doing here? Is this just a pre-production camera that's not tuned in well?:

http://www.fredmiranda.com/forum/topic/1497323/31#14100315

I feel rather happy that my 80D can still beat Canon's latest full frame DSLR in low ISO!

But I worry now that Canon will establish a pecking order and the the images from xxD will always be worse than 7D and so on, never the same or better. Very glad that I didn't pre-order the 6D Mark II.

Or maybe Canon will just give up certain types of photography and only develop for action photography now?

We'll have to wait and see for retail SKUs and more throurough reviews. This is just a preliminary result with demo camera and very probably beta software. After all, this is a new sensor and may very likely need a new demosaicing algorithms to start with.

But I full understand your concerns. If this would really be true, than Canon deserves to take a full hit in sales for this. However the realist part of me believes that this is fluke and since Canon themselves confirmed, that 6D II sensor is same technology as 5D IV or 80D, I really seriously doubt those results, until they have been either proven or disproven by multiple reviewers out there...

So this means that 700-800€ 77d has better DR than 2000€ 6d? Strange, realy strange.
I hardly believe.

 

[meho1a]

I am new to this forum but i realy like to read it. Since i have a fealling that a lot of you are pros with huge experiance. I would like to ask you what does this surprisingly low DR results mean for landscape and macro? I thought to upgrade from 600d. I was thinking about 6d mk2 instead of 80d. I quite frequently raise shadows to show more of the background at macro and even more for landscape. This are also my most frequent photos i take. Therefore i thougt that DR is very important for better photos. What do you think. I am realy surprised about these results. Kind regards

 

[fentiger]

there's always ND grad filters to work around these problems, if you was a serious landscape shooter you would be nuts not to have these in your kit bag

 

[Mikehit]

The criticisms of the 6D were its low grade AF and how it needed a tilty-flippy screen.
Its got those so now people complain about its dynamic range.....from one test with images from a camera of unknown provenance.

Well now, actually no. You don't want a strong light source actually in the image, as it will cause flare, making the shadows more difficult to analyse. ;D

+1. We'll know how true this is in time, but my gut says this is a smooch-your-fingers masterpiece campaign of kompromat going on here.

A person on another thread -- who I believe to be a real person, not one of the many pushing this poor DR thread -- just cancelled their pre-order on the strength of this 'proof'.

It seems strange, though, because the truth will be out shortly, and the cancellation or prevention of a few pre-orders can't mean much against the enthusiasm if this turns out to be false. Just seems like there's very little to gain by this.

Performed by one random person on the internet with no controls, credentials or credibility.

Oh yeah. Canon is doomed. You all better cancel your preorders and start whining.

Yes it does happen every time....in fact the person in question has done these same tests for the last 4-5 bodies released by Canon on early pre-release RAWs and guess what?.....every time his results were confirmed as correct by bigger sites like DXO and photonstophotos etc....

Remember Canon RAWs have a masked area making these type of tests really easy unless the entire photo is dark.

Well, some people here on CR complain that Canon doesn't innovate, so they should be more like Nikon and Sony. Nikon recently launched their flagship D5 with less low ISO DR than its predecessor. So maybe Canon is now innovating just like Nikon. That should make people happy, right?

 

[Mt Spokane Photography]

I cancelled my order, but only because I decided I'd prefer the 5D IV, not due to DR.

I am still undecided as to a backup for it, a 6D MK II is still a possibility.

If it turns out to be a high ISO killer instead of low ISO glory, I'll be very happy indeed. Both would be bacon.
