X-e2 focus tracking sequence

tried out the X-e2 @ 3fps with 55-200 at 200mm for tracking performance with my Cairn terrier, Taz.

I wouldn't say its SLR standard. It lost it at the start (maybe my fault), but I was quite pleased with the last few shots when it caught up.

When using continuous drive mode, Fuji cameras do not focus between shots like most DSLRs. Focus and exposure are locked at the first shot. In your example, the camera did not catch up, but the dog moved into the area of focus.

"The adoption of the dual CPU, improved computational performance has doubled the processing speed when compared with the previous generation processor** and working in tandem with the high-speed signal readout of the X-Trans CMOS II sensor, raise the maximum continuous shooting speed to 7.0 fps (max. approx. 28 frames)*5, and achieves a maximum continuous shooting speed of 3.0 fps with AF tracking." http://www.fujifilmusa.com/products/digital_cameras/x/fujifilm_x_e2/features/index.html

The last 4 shots in sequence were all definitely tracked by the camera (ie I had shutter released down all time).  If the camera had locked focus on the 1st shot, the dog would have been an unrecognisable blob when she was close up.  So I think the X-E2 does track during sequence.

Incorrect (atleast on this camera). That is actually a new feature of the x-e2 and the 3fps burst mode, it refocuses for every shot

You posted 10 shots, but they are not all a single sequence. The shutter was released between shots 2 and 3. So you have an 8 shot sequence beginning with the 3rd image you posted. This is clear based on the time stamp in the EXIF data.

When I first looked at the sequence that starts with image 3, it seemed that the dog was out of focus beginning at the far distance, then came into focus at the near distance. But now, having looked at the sequence more closely it does appear that the camera changed the focus point during the sequence.

It seems Fuji failed to update the manual regarding this change. The X-E2 manual (like other X cameras) says this: "Focus and exposure are determined by the first frame in each series"

There is no mention in the manual of this feature. Neither does it show up in the Fuji marketing materials.

Do you have a link that talks about this? Seems like this only happens while you have the shutter half-pressed (per the manual).

Here you go:

From dpreviews preview

"The 3fps Continuous Low mode will show live view between frames, and attempt to refocus on moving subjects, but only if the camera is set to continuous focus mode (otherwise it just replays recently-taken shots, like the high speed mode)."

Possible but not likely knowing typical Fuji focusing capabilities.

Why the manual makes no mention of this? Or Fuji's own website/marketing materials?

It makes me wonder if dpreview got it right (or if Fuji forgot to mention it).

Not sure. I think I heard them say it on one of the 3 part videos on the x-e2 walkthrough by the fuji guys on YouTube but I can't remember for sure. I think he explained the difference between 3 for and 6 god the same

Re: X-e2 focus tracking sequence

This may mean three things. Either Fuji will do something with firmware, Fuji's Xpro replacement or new XYZ supposed camera does better OR one still needs a DSLR for this type of stuff as simple as a dog running Sports related, wedding, event etc..

I wonder if their are any p&s that handle action well as a less expensive alternative to a DSLR, got some research to do.

See my post above... It is on the web site at least.. not sure about the manual.. :

"The adoption of the dual CPU, improved computational performance has doubled the processing speed when compared with the previous generation processor** and working in tandem with the high-speed signal readout of the X-Trans CMOS II sensor, raise the maximum continuous shooting speed to 7.0 fps (max. approx. 28 frames)*5, and achieves a maximum continuous shooting speed of 3.0 fps with AF tracking."http://www.fujifilmusa.com/products/digital_cameras/x/fujifilm_x_e2/features/index.html

Re: Looks like Randy is not right... check page 57 of the x-e2 manual

Below is what the x-e2 manual says on page 57 (Continuous Shooting (Burst Mode) section). Pay attention to the last sentence (in bold) which confirms that focus (together with exposure) varies from frame to frame when in Low speed (3 fps) burst mode and Continuous focus mode.

"Focus and exposure are determined by the first frame in each series. The flash turns off automatically; the previously-selected flash mode is restored when burst shooting is turned off. To allow focus and exposure to vary automatically from frame to frame, select Low and rotate the focus-mode selector to C."
