Janneman's dynamic SR-Test, mufflers needed [imgs]

Go to last post
hmm, guess the situation when holding the camera and a mobilphone with vibration alarm in the same hand - there is a REAL need for SR ...

(how could I ever mean I could avoid buying a new camera ...)

Best, Bernd

A great post and shows it DOES work. But as a newbie around here, I was wondering exactly how much, in terms of stops, the VR is supposed to help. Doing a search on this board is no good because it take forever to wade through the results!! The amount of shake in the unVR (deVR? inVR?) shots in this thread would say maybe a couple of stops?

I am not sure. I think it also depends on how shaky you are by nature

So you were sitting on the running lawn mower while taking these
pictures? That's amazing! And a very ingenious testing method.

I believe he just attached K100D to a parked lawnmower with engine
running to make a vibrating test platform: notice that both frames
in each test (SR on and SR off) are identical which indicates
shooting from the same location. Driving around and taking two
absolutely identical shots (same composition) would have been
impossible.

Not for me, lowest gear used....
I did try the parking trick but my hand was too steady for that....

Still, the testing method is indeed ingenious!

That's a great technique - I was thinking of doing something
similar when I was doing a head to head test on the KM 5d and my
K100d. I was thinking more along the lines of a back massager on a
table. Just doesn't have the Tim Taylor element to it though. Bravo.

I'm under the impression on mine that the SR can basically keep up
with anything that is thrown at it as long as the camera motion
doesn't exceed the range of motion of the sensor. Is this your
experience?

Not sure yet, it was fun trying but I am not a true "tester"
GossCTP said:
If it is true, then tests like these are a little
exagerrated for the real world, as the peak vibration is much more
constant on the hood of a tractor than it would be in one's hand.
Never the less, it does show the validity of the system and what
can be done if one has a steady techinque. I think that is why some
forum members are saying they get sharper shots if they relax with
the SR. It reduces the peak vibrations and allows the SR to do its
thing.

We should be careful to get out of an experience only the wisdom
that is in it—and stop there; lest we be like the cat that sits
down on a hot stove-lid. She will never sit down on a hot stove-lid
again—and that is well; but also she will never sit down on a cold
one any more. - Mark Twain

Just curious. It appears that both the clear photos are more cropped than the fuzzy ones. What is the reason?

BTW- I ask because I just had my camera destroyed by a set of batteries and am in the market for a new camera (k100 is near the top of the list). How would you (since it seesm you ahve an array of cameras or at least experience). Measure up with the others in its balllpark (D50, E500, rebel Xt)? Feel free to answer this one somewhere else if it's too off-topic (email me?).

First set of pictures were taken 11 sec apart, second set 6 secs apart in the order shown (from the EXIF). I think the mower/tester/camera were going forward and have just moved that much to make the photo cropped differently.
