Is X-T2 Dynamic Range on par with FX?

Depends on what you compare it to. Shot noise: obviously not, read noise: yes or no, depending on where you come from. Since DR is a combination of both (with minimal read noise and high ISO-invariance as a prerequisite), your mileage will vary. 

 

For example, even the entry-level Fujifilm X-A3 matches the DR of a ultra-high-end Canon EOS 5DS R landscape camera, but it can't beat a Nikon D750/810/850.

For those who have moved over from full frame DSLR do you think the X-T2's sensor performance in terms of landscape dynamic range is on par?

 

Very close.

 

DR chart

 

An issue to consider with the X-T2 is Fuji's decision to set the camera's base ISO at 200. Notice in the linked chart that Bill Claff measures the X-T2 DR at 10 stops/ISO 200 and the 810 at 10.28 stops/ISO 200 -- .28 isn't a big deal. Fuji, for whatever reasons, has set the camera base ISO high relative to the sensor's real limits and capability. Leaving the X-T2 at ISO 200 there's considerably more there if you increase exposure. I've gotten into the habit with my X-T2 of leaving the EC set to +1 and will frequently take the photo at +1.3 to +1.7.

 

Consider this comparison between the X-T2 and Sony 6300 which are both using the same Sony sensor. Sony selects base ISO as 100 and Bill Claff measures nearly 1 stop more DR for the Sony camera:

Well it's the same sensor and it doesn't really lose a stop of DR because it's in a Fuji camera instead of a Sony or Nikon camera. Same sensor is also in a Nikon D500 and its base ISO is 100 and sure enough its DR performance matches the Sony 6300. The ISO ratings that camera manufacturers assign are not ISO ratings for the sensor they're for the JPEG output of the camera's image processor.

 

Still the 810 and now 850 are better, but if you expose for the sensor in the X-T2 it's close.

      X-s10 Fast shutting 20/30 fps crop ES

      By mapoett · Posted

      Hello. Thankyou,now Is all more clear: I have take some time in your link. Let tell you. I has totaly forget this machine have "compress picture option" and not Only "compress lossless" anyway not change the experiment. RAW  and this last two format look like same result about Number of recording picture. Can tell all results in this: in raw you can make 17 pictures for second. Is wrong. Is about One single Press and wait buffer. Full 30/20/10/8 not change. After 17 Need Press again. You not can Press before "redgreen light recording Is on".   With preshot you can have 25  are more 7 pictures . The story change Only in jpg shot only. In jpg at 30 you have 30 picture but redgreen light off very Fast so you can shot very quicly. At 20 shot Is about start look like infinite shot. 60. So the best performance are this last One  about Speed and recording picture after camera working witout big limit. I want take a shot about Italy cyclet Just for passion. I think i Will use this last setting.  After Need check when battery not are full change and ambient temp.  Anyway my cam look like exactly specific about you link. Im Happy my cam working perfectly.

      I do not use Flickr, so I do not know what their BB code is. All I did was copy the second link you provided, (starting at https: and ending at  _k.jpg — leave off the [img] and [/img] tags) and pasted it into the message. After a moment, a message popped up asking if I wanted to paste it as the image or as a plain link. I did this twice, the first time I had it paste in as the image and the second time as a link. Nothing fancy or tricky.

      So do I just copy the BB code from flickr and paste it anywhere on the page like other forums or is there some other trick I need to perform to get it to post?

      X Raw Studio Doesn't Create Drive for Camera When Connected

      By JovialLich · Posted

      All software is the latest between camera and app. All settings are correct on camera. I have both lossless and uncompressed RAW files on the card in the camera. I have been up and down every reddit thread to no avail and am losing my mind… I’m doing all of the right things. It even sees my camera. It just doesn’t create the “drive” for it (see attached image screenshot).  Please Help!

      X-T30 II Eye Sensor + LCD Image Display viewmode not working

      By grizzski · Posted

      Not sure how to delete threads, but I figured out what was wrong. In short, I was partially misunderstanding the view-mode's function. Also, the "+LCD Image Display" part requires that you have the Image Disp. setting set to anything but Off. Then it will display your last image on the LCD. If it's off, it's behavior will be exactly like the plain Eye Sensor setting.
