RE shutter release delay

[iphoenix]

My RE seems to have a significant delay between pushing the button and the shutter releasing (guessing around 1/15 to 1/8 of a second).

 

Is this normal, is it something I can fix myself, or does it need professional attention?

 

The camera seems to be perfect otherwise.

 

I've tried new batteries and different lenses.

Morning!
 

Seems, that your mirror damper needs a clean. Unfortunately the damper is not easy to reach. (located behind the depth of field preview lever)

 

On the Minolta XD , in this respect similar, it's a relatively easy repair, but on the Leica R's it requires some more stripping....

 

Have a look on the open XD (did the repair some years ago).

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

It's one of the main problems of the Leica R series before the R8 and after the R3

[a.noctilux]

Delay is normal on R4/R5/RE that I used.

 

From memory, the time lag is 80ms-100ms a much longer than about 20ms of Leica M from same period.

I have 2 R4 bodies, and the delay on one is significant, while the other is reasonably quick. The mirror damper might explain it.

[wagner]

The Leica R4s has a tested delay of 160ms. (photo Revue 1985)

 

For comparison :

Minolta X 300: 90ms

Pentax Super A 150ms

Contax MA 110ms

Canon Al1 80ms

Nikon FE2 60ms

Canon T50 170ms

Ricoh XR P 370ms

 

The shutter should release to the ear immediately , If you notice a delay, than it´s a sticky damper.

 

So, the Leica R was not the best , but not the worst either....

I wonder what the shutter lag of the Leica S is or the Leica R8, or the Nikon FM3a in electronic or mechanical mode. etc.

Thanks to all.

 

I've been judging it against my experience with Nikon F, F2, F3, Nikkormats, etc. It seems maybe I should improve my ability to anticipate movement in action shots when using the RE.

Just use the Nikon´s instead and be happy again.............kidding !

Three major reasons why some SLRs "of a certain age" - spreading from the 1970s to the 1980s - have increased shutter lag or delay:

 

1) Trying to be more "rangefinder-like" - a damper (shock-absorbing piston) or some other means of spreading out the motion and sound of the many actions of an SLR to reduce peak camera shake and volume.

 

Leitz/Leica, of course, was especially sensitive to this, since their past reputation came from the smoothness of RFs, and they really wanted to replicate that in their SLRs, at a time when the future of the M system was not assured.

 

But nothing is free in engineering, so reduced shake and noise led to slower response.

 

1a) Eventually, as cameras began to include built-in motor drives for cocking and film advance, one additional technique for producing (1) was using motors or solenoids in place of spring-power to "drive" the mirror up and down and the aperture open and closed (e.g. Canon T50 - but others as well). The motor could be accelerated/decelerated more smoothly to slow rather than slam to a stop - but it took more milliseconds.

 

2) The advent of shutter-priority and "Program" automation. The early "camera sets the f/stop" mechanisms were not always very accurate, so it was the norm to slow down the operation so that either: the aperture-stop-down mechanism could stop more precisely - OR - an intentional pause was built-in after stop-down but before raising the mirror and opening the shutter, for the meter to sneak a last peek through the stopped-down aperture, read the actual light coming though, and tweak the electronic shutter speed to correct for the real aperture acheived. I.E., the camera might tell you you had set 1/250 and would get f/5.6, but only achieve f/4.5 (or f/6) and correct for that with an actual shutter speed (set "on the fly" after a new meter reading through the stopped down aperture) of 1/350th or 1/210th.

 

Nikon's first "PASM" camera, the FA, like the R4 et seq. also had a rather rubbery, squishy, s-t-r-e-t-c-h-e-d-o-u-t shutter response. Especially compared to its clockwork siblings, the FM/FM2 and FE/FE2.

 

Eventually, more advanced engineering (lighter materials with less inertia, more precise aperture-drive mechanisms placed within the lenses themselves) permitted the shutter lag to reduce again.

 

I don't know about the R6/6.2. My impression was that the R7 was "snappier" in response, but that may simply have been that their shock-absorbers were younger and more "fresh from the factory."

"Three major reasons why some SLRs "of a certain age" - spreading from the 1970s to the 1980s - have increased shutter lag or delay"

But not for the Leicaflex SL(2)- production '68 - '76

[wagner]

You mentioned the Nikon FA, Adan and you are quite right, the camera was much slower than the Nikon FE: 215ms...

Did just read a testreport Leica vs Contax from 3/2000. And there they mentuioned 208ms for the R8 and 118ms for the R6.2

And the Contax Cameras: RTS III 131ms and for the S2 46ms (Which is actually +- the same value, which was mentioned in a brochure for the Leicaflex)

So looks like mechanical shutters have less lag than electrical

[pascal_meheut]

I've always wondered if the R shutter lag was so bad. I used them for years to shoot racing cars and they seemed ok to me, not the fastest but nothing terrible.

I bought a R6.2 (nostalgia) and found it slow but a softie made things better. Anyhow, I started to try to measure the shutter lag myself. I shot an iPad screen running an App. Each time the arrow reaches a 5 sec mark, I take a picture and I look at the digital value.

Of course, I do it several times and computes the average.

First, I tried to check that the results were "more or less" correct. So I tried with an Olympus OM EM1-II and found 30ms. This is coherent with this site: http://store.lightningtrigger.com/compatibilty.aspx

The M10 gave me 32ms and 42ms in Liveview.

Then I tried with good old film cameras. Here are the figures rounded to the closest millisecond:

R6.2: 40ms

R5: 40ms

R9: 35ms

F3HP: 30ms

M7: 27ms

Of course, this is not as precise as it could be: my response time is taken into account and I may anticipate sometimes (but the figures do not show it).

Anyhow, I do not see how we could get the figures above, i.e. 208ms for the R8 and 118ms for the R6.2. 

As I said, I've used the R8 intensively shooting race cars and 2 tenth of a second of shutter lag is not something that would go unnoticed.
