Close-ups of aperture and shutter operation

[videogamemaker]

According to Fuji, shutter lag is in the order of 0.01s, that is Action 1 and part of Action 2 [shutter closes] has to be completed in ~10ms. The video looks about right.

Action 2 duration is largely dependent on what shutter speed was set. Even a 1/30s [33ms] shutter speed will make the whole action look slow.

When I get around to it, I can take the whole video duration and isolate Stage 1 and Stage 2 duration......

I am satisfied that the X100 seems fast enough...and sounds OK as well.

Isn't it possible that they define shutter lag as only the time from half press to full press? Or, if as I posited, the half press is shorter or longer depending on aperture setting, the lag of only f/2 where the aperture doesn't need any time to engage?

The time from full depression to shutter actuation in that video was for sure longer than .01 seconds. Also they list in a text over the screen that the shutter speed is 1/4,000

Of course it is possible...that is probably why Fuji cannot and did not give a hard answer. It is the same game auto manufacturers quote horsepower figures...measured at where???

Whatever the total shutter cycle time may be, the X100 5F/s support was long announced. So, a 200ms/exposure is the total time budget.

Much of lag time in "capturing the moment" is user dependent. Think about it this way: MF involves specific decision making, and slower than in-discriminant zone-focusing; ZF is slower than AF but the zone can be pre-defined. AFL+recompose is probably just as quick, but voyeur "street photographers" want to sneak up on the subjects... All that was another long-winded debate elsewhere.

I am way past all that...decades ago.

All I want is a decent digital camera with my favourite FL lens [35mm eqv.] and support automation if I chose, or totally manual if I don't.

"[X100] is my idea!"

Paying $1000 or $1200 has little meaning. You want it now, you buy it now...prices might drop tomorrow, or not......

It isn't quite this simple.

Let's say that a single exposure, from full depression to shutter close is .6 seconds, .59 for closing the aperture at the half press, and .01 for the shutter at the full press.

Now let's say you have multi-shot enabled, and push down the button and hold it down.

You have that first .59 seconds for the aperture to close, but now it's at that setting for the remainder of the 5 shots, because you are holding down the button. Now you have that .01 seconds for the first shot, whatever recovery period happens to reset the shutter, then the next .01, etc.

It's perfectly possible to have a .6 or .7 second single shot shutter lag, and still have 5 fps possible.

Frankie; Did you see the rumor post concerning Nikon CLS being integrated into the x100? The Fuji hot shoe doesn't match Nikon's, but that doesn't mean the internal flash couldn't be used in commander mode. It's an odd arrangement if the rumor is accurate. My Fuji S5 (Nikon D200 + Fuji Sensor & firmware) is CLS compatible, so who knows?

Nobody knows much about the X100 firmware. I have deduced a structural diagram some time ago...but I have little interest starting a round of meaningless debate.

Nikon and Fuji had worked together before, why not now?

Of course not. What about buffer size, write to SD time...?

40 years ago, the Nikon F2 could do 4F/s with its motor drive, and a few years later the Hi-speed version achieved 9F/s...a whole roll gone in 4 seconds. Took longer to reload.

I am way past camera recycling speed also.

I don't care about the FPS, I was just commenting that it can't be used to divide a second for the exact shutter lag of one shot.

I've never used my camera's multi shot mode, but I care that it has crazy short shutter lag and is always always ready for a 2nd shot, if I see a better expression right after my first shot.

In my own photography, I practise one-shot-kill.

If shooting in manual exposure, will the aperture have to open and close
each shot or will it be like a rfg lens and remain at the chosen setting?

It was in manual for this video. The question will be, is there a menu setting that links the aperture to be "always on" or if it will always need to wait till shutter half-press to engage.

"In my own photography, I practise one-shot-kill."

In my photography, I practice the technique of shooting as many frames as quickly as possible hoping I'll get one good one

But seriously, I agree. Single shot is the way to go, but quick backup to second shot always helps Never know when they'll go nuts and punch the copper...
