Close Examination of Fuji X-Series Lag Time

Just for information, for anyone interested in static testing results...

Having run tests with the new firmware, have found that the issue of variable 0.2-0.5s shutter-press to image-capture lag with the 35mm, 56mm and 60mm, when in MF and stopped-down, still remains after this software update.

I just got somewhat caught up in finishing this thread. Could you please dummy it down for I got confused by all the info and charts probably due to a mixed of some laziness or impatience on my part. I got that it occurs worse with you 56mm especially stopping down and adjusting focus prior while in MF.

In my list I have the X-E1 with 18~55, 55~200, 14 and 60 macro. Would you say the improvement in delay time has not improved much or at all with having an updated X-T1? I almost always set my camera in M but use the AF back button. There are aspects I think I'd appreciate in upgrading to the X-T1 but it is a bit disappointing that the way I shoot I may not see enough or any difference in response time.

Thanks for all your work I would never get to myself.

Hi John,

Sorry for the late reply. I have both the X-E1 and X-T1. I have to say that yes, the X-T1 feels faster in most aspects to the X-E1, and yes, the AF, after the latest firmware updates, now seems a little bit better in both cameras.

To your question, well, the X-T1 is a better machine than the X-E1 in many aspects. But you may be a little disapointed with pure response-time difference, since the limiting factor for speed (both AF speed, and MF lag) is less camera-deppendent and more lens-dependent. The place where the X-T1 out-shines the X-E1 it is AF in lower light, where it seems much more able to acquire and stay focused, and if you do a lot of shooting in lower light, then yes, the X-T1 is the way to go. To be honest, the X-T1 is just a nicer camera to handle when in MF too, with that big viewfinder.

So, yes, you might be disapointed upgrading if looking only at speed-wise point of view, since the lenses still take time to do anything on whatever body thy are on, but there are so many other factors that make the X-T1 better, overall, so if you are happy with sticking with the X-series system and its 'features/quirks', the upgrade is a good one.

Cheers, Cass.
