Second question is 5 minutes...setting a new personal record this morning... :)

 

Was curious if anyone has measured the dynamic range of the X100S (or perhaps the sensor)?

 

Not looking for info about turning on the dynamic range settings in the camera. I am simply curious if anyone has measured (with the Sekonic software, for exmaple) what the true DR is for this camera?

 

Seems quite good to me, but was looking for something specific.

 

Thanks again for all the great knowledge this collective has to offer!!!

Thanks for the suggestion, but what I get is a ton of returns about the dynamic range setting feature of the camera.

 

What I am looking for is a number, and curious if anyone has it. I presume the DR to be in the 8-9 stop range, but wanted to see if anyone has actually tested this.

I havent done this test as it doesnt rally bother me as I dont tend to drive my photography by the dynamic range alone.

Yes I want great dynamic range and is the DR of the X-E2 better than the X-E1/X-Pro1 range is a good question?.

 

I think that there are reports that the DR for the X-E1/X-Pro1 is 9 stops but I am not 100% on this number.

Since I dont have a camera with X-Trans v2 sensor I cant test until I get my X-T1.

I haven't an exact number, but I would hazard a guess that it is between 11 and 15 stops for raw.  I am basing this on negative film which was around 8 – 12 stops and transparency film which is around 4-5 stops.  I would say fine JPEGS have about the same dynamic range as transparency film too.  These numbers would be expected above a correctly exposed image of course, but probably less before actual clipping of the highlights.

In addition to my previous reply:

X-100s can extend the DR by about 1 stop (in the dark area) at DR 200 and ISO 400 settings and by another stop (highlight this time) by electing ISO 800 and DR 400 modes.

To answer your question: between 8 and 9 stops depending on the settings described above

I just remembered one of our fellow Forum member "rtx" actually measured the X-E1 sensor's analog dynamic range to be 13.5 stops.

(scroll to the end for his DR calculation)

 

Wouldn't it be a huge shock if the X100S' Xtrans sensor's DR was less than this?

I know I'm bucking the trend, but I do not enjoy the images I get from my X100S as much as I did from my X100.

 

I seem to like cameras with big pixels as opposed to a lot of them. I loved my 10mp Canon 40D too.

I do agree with this statement.  I loved the images from my 5d classic more than I did from my 5dMKII. Pixels are only light buckets and I prefer larger light buckets rather than lots more smaller ones.  I'm sure there is a logical reason to have more light buckets crammed onto a same size sensor, and that may well be something to do with better overall resolution. Which is fine if you want prints the size of a house I suppose.

Tell me more about the sekonic software...
