When using the OVF, does the battery drain just as quick as using the EVF? I’ve noticed no discernible difference. I still like using the OVF and frame lines, it’s a unique experience, being able to see everything before you compose and take the shot.

I will reevaluate my battery usage again on my next few outings. Perhaps I’m just used to dSLR battery life still.

Perhaps I’m just used to dSLR battery life still.I usually keep mine turned off as the Fuji cameras will usually boot up faster than the will "wake up."   The only time I had the change out a batter was one day where I had my 90 on and was using the EVF instead of the OVF and there wasn't a lot of time between shots so I kept it on most of the times.  I also was shooting in burst mode as I was taking shots of birds.  But that was an anomaly.  Yes when my D800E would go 800 shots on a battery - it took a little getting used to a mirrorless.

Even if you use the EVF and boost mode all the time.Battery life is still one of my frustrations with mirrorless. I'd prefer bigger batteries that last longer even if they make the bodies a bit bigger or weigh a bit more.

It’s not a huge issue, I’ll just carry another battery with me, I do this any way with my DSLRs.My underlying question is though, is the Xpro3 still doing all the underlying processing while the OVF is being used compared to the EVF? If so, this would make sense to me that battery consumption would only be marginally better using the OVF.EVF still consumes more power, obviously, and the camera has to render an image in real-time, but, considering all of that, what is going when the OVF is being used?

On the X-Pro 2 battery life is longer if you use only the OVF. There are so many variables it's hard to quantify how much longer. For the way I shoot it was in the 15-20% range at best.If you are manual focusing that should add some battery time too.I'm not sure what you mean by "is the Xpro3 still doing all the underlying processing while the OVF is being used compared to the EVF?" The camera does everything it needs to do to function in both modes. The EVF draws a lot of power. It's basically a tiny TV.Back when the X-Pro 2 came out, some people recommended turning off all of the information shown in the OVF that you don't use to lengthen battery life. I never tested whether that actually made a detectable difference or not because I always turn of the display of information that I don't use.The "turn it off whenever you aren't using it" trick works for all the Fuji cameras that I've used.If you're carrying the camera with you everywhere and shooting a few pictures a day as you go about your business a new battery should last a week or two between charges.In my experience, the battery basically gives you about three hours of active use of the camera. It can be twenty minutes a day for a week or three hours in one go. That could yield 25 pictures over the course of a week or 900 pictures taken in three hours.Hope that helps.

I was on a 4 hour outing actively using my camera all day with the OVF. I still had one red bar of battery left but I know it was about ready to die because there is a lag between when the shutter button is pressed and a photo is taken.So yeah your usage coincides with my observations too.

You’re saving a little power as a result, but still drawing significant power at the same time.An easy way to see this is with the camera on, your eye away from the viewfinder, the LCD closed and the aperture ring set to A - if you point the camera towards a light source, and then to dark, you’ll see/hear the aperture blades adjusting for the changing exposure. The camera is constantly monitoring and responding to the scene, regardless of whether it’s displaying that scene in live view.I do find the the X-Pro3 quite efficient compared to other Fujis, since by default it doesn’t power the viewfinder or the rear screen with your eye away from the finder and the screen in its usual closed position, and I find the battery life to be very good for a Fuji - but I do habitually flick the power off when I’m not actively shooting/composing.

But just in case I missed it... with boost mode on, battery will go faster regardless using EVF or OVF. I suggest to check if you turned on the boost mode. And if the goal is to make the power last longer, switch to normal mode.I leave it at boost mode and just bring 3 Fuji batteries for each body I use plus a medium capacity power bank as backup.

Don't use the ERF with the OVF if you want to save power.
