those were all at 1/1000 sec

i just picked this up today from the post office bought off of ebay - excellent condition even the light seals are only a few years old
ran a test roll through it on my way back from the post office - picking that up tomorrow from the lab
went home and cleaned the lenses
and used a can of air to blow away any dust inside the camera

the shutter goes "ka-chonk"
and when i put my hand on the lens when i press the shutter i can feel the vibration of the mirror lifting up and returning down through the lens - its a pretty significant vibration - doesn't seem like i should feel that

i'm going to run another test roll through it tomorrow
am wondering if the air can i used to blow away dust did something to the camera
like maybe dry out lubricant that makes the mirror less ka-chunky
i didn't notice it when i was shooting my test roll today, but maybe i just wasn't paying attention
it seems different now that i blew air inside it, but its also like 2AM and i'm tired
to me, it seems like something funky is going on with the mirror and not the shutter blades
should i try baking this in the oven

couldn't find any xd11 vids on youtube to compare but this srt101 sounds way less kachonky - go to 7:20 point

Sounds O.K to me, but you don't say what the shutter speed we are listening to is.

those were all 1/1000 sec

[chij]

here's 1/15 sec
http://www.youtube.com/watch?v=LwTeWLVUUUc
and 1/2 sec
http://www.youtube.com/watch?v=73buwd7Q9hw
to compare with the srt101 video

[chij]

i think its better now
this vid is 1/1000 sec again
http://www.youtube.com/watch?v=5NMeuSyKpiM
but notice how the latch at the bottom doesn't go all the way to the end like it did in the original 4 vids
an hour ago it was going all the way to the other side for all shutter speeds - as you can see in the first four vids i posted (1/1000sec)
and now there's less vibration and its not kachonky, just ka now

but the latch goes all the way to the other side when the shutter speed is 1/30sec or slower
so its still very kachonky at 1/30 or slower
if someone has an xd11 and can see if theirs also goes all the way to the end on shutter speeds 1/30 or slower

[chij]

weird, if i hold it upright in its normal shooting position the latch goes all the way to the other side at 1/30 or slower
but if i lay it on its back pointing up, the latch goes all the way to the other side for 1/60 or slower

what the heck is going on

[chij]

uh oh
if i have it on shutter priority it does what i just wrote - so maybe that wasn't 1/1000sec in that last video because shutter priority will change the shutter speed if the exposure is wrong
but ifi have it on manual than the latch goes all the way to the other side for all shutter speeds and its very kachonky

A camera is a machine for taking pictures stop torturing yourself trying to find faults with it shoot some film before you jump to any conclusions, enjoy using it and get a life.

mirror damper foam could be bad,hence the noise

I won't even try to explain how you can't determine shutter speed from mirror sound.

that lever is for the aperture diaphram, in shutter priority it will move to differnt points based on the light levels, thats how shutter priority works, you set shutter and the camera adjusts aperture to get the correct exposure.
RTFM

I compared the sound my XD makes to your videos, and there is a difference. The quality of your recording my explain it, but my XD makes a kind of shuffling noise when it's fired - quite muted - there is no clacking sound like I'm hearing in the video and no vibration that I can feel. I just had mine CLAd, but I don't recall it sounding like that even before the service was done. Not being able to actually compare the cameras side-by-side, this may not be a valid guess, but I agree with fstop - the mirror foam bumper may be shot.

Are there any black specks in the viewfinder that would indicate deteriorated foam flying around in there? The way the camera is built, it's difficult to see the mirror bumper and some disassembly is required to replace it, so if the seals weren't replaced by a professional, there's a chance that the bumper wasn't renewed.

The XD is a great camera and well worth the cost of a CLA to keep it hummin'.
