Slow eye-sensor EVF switching response with UHS-I cards

Here's another X-T2 bug... I didn't notice this behavior on the X-Pro2 but don't have access to one anymore to confirm.

 

Here's the problem. With a (fast=95MB/s) UHS-I card in the camera (in either slot, can be in addition to a UHS-II card), the eye sensor takes up to 4-seconds to transfer the preview from the LCD to the EVF when first turning on the camera and bringing it to your eye.

 

UHS-II cards don't seem to have this delay.

 

If you put the camera to your eye and THEN turn it on, there is only a half second or so delay, which is fine, but I have a decades old habit of turning on/unlocking a camera before I bring it to my eye.

 

This means I'm having to use $40 UHS-II cards in the X-T2, even though a $12 UHS-I cards are plenty fast enough me.

 

I've tried PNY Turbo Performance and Sandisk Ultra UHS-I cards---with either the X-T2 exhibits this bug.

 

Is anyone using a UHS-I card with the X-T2 that doesn't cause this delay?

Can't reproduce this behavior with my X-T2 and SanDisk Extreme 128GB(80MB/s) / 32GB(60MB/s) combo. Do you have boost mode activated in the Fuji?

 

It happens with boost mode on or off. I should have mentioned that obviously the camera has to be in the 'eye-sensor' view mode. Sequence of events is: turn camera on with it away from your body (so that LCD comes on initially), and immediately bring the EVF to your eye. It's possible that the X-Pro2 had the same behavior and I just didn't notice because of the optical viewfinder---with the X-T2 your're just staring at a black screen for several seconds so it's pretty disruptive to shooting.

 

After the camera has already been on 4 seconds or so, switching to the EVF seems just as fast with the UHS-I cards as with UHS-II cards. I also tried disabling the shots remaining indicator from the EVF display in case the EVF was waiting on the card for that information, but that didn't make any difference.

One interesting little update. My Lexar 1800x UHS-II micro sd card's adapter broke. So I put the card in a UHS-I adapter. Well, still no delay when switching to EVF! So it seems that this UHS-II card using only the UHS-I pins works fine. That's not super encouraging though, because it means that, no matter the specs, every card I buy is a total gamble, with the odds strongly favoring this delay. I think I'm about to order a Sandisk Extreme Pro UHS-I card, and see if that helps (I never needed UHS-II anyway, just want to get away from this damn EVF switching delay).

OK. The weirdness continues. I bought a Sandisk Extreme Pro UHS-I card. The problem is greatly reduced (delay shortened) with this card, but, and here's where it gets really weird, it's still a greater delay than the UHS-II Lexar 1800x card using only the UHS-I pins. This is weird because the 1800x card is SLOWER in UHS-I mode than the Extreme Pro. So it definitely seems like the read/write speed doesn't have anything directly to do with it, and it's some other card compatibility problem (and I tend to blame Fuji here because I have several cards that work fine in other devices but produce read/write errors when used in certain Fuji cameras).

 

I guess the Extreme Pros are OK, as it's only $20 for 32GB (vs the $40-$60 for a 32GB UHS-II card). The delay is still noticeable, but not a hindrance like it was with my other UHS-I cards (1-2 seconds vs 3-4).

Thanks for posting about this kimcarsons, I had a much slower card in my second slot as overflow and swapping it has increased the responsiveness some. I leave my camera on while I shoot using eye sensor viewfinder only mode, so I don't run into this delay much, but you never know when you'll need your camera on in an instant!
