Close Examination of Fuji X-Series Lag Time

Update: X-Pro1 Test - 35mm and 56mm

In case anyone is interested...

Just had a chance to do a quick and dirty test in the local camera store with a brand new X-Pro1, 35mm and 56mm lenses (armed with stop-watch!). Results show as follows: -

35mm

1. Wide Open: 90-100ms

2. Stopped Down F16: 190-210ms

3. Stopped Down with Focus Adjust Causing Lag: 240-280ms

56mm

1. Wide Open: 60-110ms

2. Stopped Down F16: 200-240ms

3. Stopped Down with Focus Adjust Causing Lag: 400-520ms

For me, that about seals it that this is a system issue. Now I know more or less how to induce the extra lag in step 3, I get the same sound differences in the lens between steps 2 and 3, and get similar lag to the X-E1 and X-T1. It was quick and dirty, only about 3 or 4 exposures for each test step, but the lag was very perceptible to me, especially with the longer EVF freeze during step 3.

While in the shop, I did a quick reality check with the Nikon D7100 and D810 they had there, not a full timing test as I was using the optical finders, just shooting stopped down, and man, shooting the Fuji side by side, sorry to sound like a broken record, but honestly with the X-Pro1, the delay as seen through the frozen EVF felt like an eternity... Press the shutter on the Nikons, and it was like a hair-trigger, just happens instantly, with or without AF...

I just so hope we can get Fuji to look at this, as I really think there is something inherently wrong somewhere...
