XG9 Battery/Shutter/Aperture mirror

Hi Guys,
I've recently unearthed an XG9 in great condition. Turns out the battery was in there for some time, not sure how long. The red light on the indicator used to go on when I did a B.C, then it came and went intermittently and now there's no light. The shutters seem not to fire occasionally but the thing is I can see the red LED's inside the viewfinder.
Q1) Not sure if it's just the batteries are dead or if it's related to the contacts. (I've rotated and turned the shutter switches). Gonna get some new batteries and see.
Q2) How critical is the aperture mirror issue. I don't see the f-stop value so I suspect it has fallen off too. Is this an urgent thing to get fixed? I don't hear anything rattling inside.
Thanks for your help. I've unearthed a beauty here with a few lenses in mint condition and would like to be this thing ready to go.

First clean the battery cap and contacts with a pencil eraser including cap threads.
the aperture mirror is located on front of the prism. remove the two screws on the front prism cover, remove the cover. you will see the holders for 2 tiny mirrors one of the mirrors fell off and must be found before it gets jambed in the mechanism.if it's not around the prism anywhere take off the bottom cover and check there. gently shake and tap the camera . the mirror has glue on the base side and may be stuck. when found re-glue to the holder.

I have a D60 and when using my new lighting kit if the aperture is faster than1/200 it creates a blackout across part of the image due to the mirror. Any solutions?


It's not the aperture, it's the shutter speed. It's also not the mirror, but the shutter.
The camera's fastest shutter sync speed is 1/200. You must use a shutter speed no faster than that. Due to the construction of the shutter, the frame is not fully exposed simultaneously at faster speeds and thus part of the image is blacked out.

Using a flash, the amount of light is controlled almost exclusively by the flash; the exposure is controlled by the aperture and the shutter speed is all but irrelevant.

Check batteries -will not work without batteries. Clean battery cap with pen eraser.

Otherwise - do LEDs light up in viewfinder? If multiple LEDs light up at once, the the aperture resister board on the front is dirty or the shutter/asa board on the top needs to be cleaned. If LEDs light up and then go out when you push the release button, but the camera doesn't release then the capacitor on the bottom is probably bad.

Finally, did someone stick a screwdriver in the motor coupler on the bottom and force it to turn? Congrats, they have ruined the shutter gears! I used to see this all the time.

I own an Olympus Evolt E-500. Unfortunately, it was dropped and landed on the corner of the case near the battery door. The camera turns on, lcd screen, flash, and shutter seem to work, BUT pictures are...


I found this camera available for purchase as brand new for $450. Spending nearly $300 to repair an older version may no be a wise choice. You may find there is a market for the camera in its current non-working condition on eBay.

With that said, to your questions. 1) It will be difficult to diagnose without seeing it, but I have a suspicion in mind.

The viewfinder picture is actually what the lens sees, bounced up via mirror to a prism that projects the image to the viewfinder. If the mirror has become dislodged and is stuck in an odd position, the image would not be projected in the viewfinder. You can see the mirror when you remove the lens from the body. The mirror should be centered in the opening but at about a 45 degree angle. If it is loose or otherwise in the wrong place, this could be the problem. If the mirror is stuck and preventing the image in the lens from projecting on the sensor (behind the mirror) no capture will be possible. Other than the optics inside the lens and the mirror, there are few parts that could obstruct the image in the lens from reaching the viewfinder. Is the aperture of the lens open? If not, there may not be enough light to see the image in the viewfinder. This would also indicate that the lens is not opening up to let you see, and may not get set to the correct aperture when taking a picture. The camera usually opens the aperture to allow you to have a nice, bright image in the viewfinder. When you press the shutter release, the lens stops down to what the program says (or your manual selection) and the mirror lifts up out of the way, and the shutter fires.

2) Can you fix it? Maybe. Again, without seeing it - its hard to know for sure what the problem is and I don't know your level of skill either.

My suggestion is to bypass the camera shop that "doesn't know what the problem is but will fix it for $270" (how is that even possible??) and deal directly with Olympus USA Service and Support by phone or email to get an estimate / factory trained tech perform the repair.

Good luck!

I advise a high school yearbook and we shoot a d100. Today it's too dark to see through the viewfinder (yes the lens cap is removed), and i ger the r06 error. I've reset the camera, removed and...


First, the "r06" message is NOT an error code. It indicates the number of shots remaining in the internal memory buffer, before the camera must prevent additional shutter actuations so that it may transfer those images already in the buffer to the memory card. This "r" number will decrease with each shot taken in rapid succession until it reaches 0. The shutter release will no longer work until the buffer is transferred to the memory card, then shooting may continue again.

As far as not being able to even see through the viewfinder, it sounds like something may be obstructing the light from reaching the meter and viewfinder. The problem is most likely the position of mirror inside the camera body. With the lens off the body, the mirror should be plainly visible at about a 45 degree angle to the opening. A side view drawing of this is below. The solid red line is the mirror in the normal position. The red dashed line is the up position of the mirror when the shutter is released.

steve_con_93.jpg

When the mirror is in the "normal" position, the light from the lens is projected on a screen so that the image is visible in the viewfinder for composing and can be metered. When in the "up" position (when the shutter release is fully depressed), the light from the lens is projected on the camera's sensor for as long as set by the manual settings or program; based on ISO, aperture, etc. At the end of this time, the mirror returns to the "normal" position.

If your D100's mirror is not in the lowered 45 degree angle position, the image seen in the viewfinder is inside the camera - not that which the lens would project. Hence, the dark viewfinder, long exposure times and - I'm guessing - severely overexposed pictures because way too much light is striking the sensor because the meter is only seeing darkness.

If the mirror is ok, with the lens removed from the body, look for the aperture lever as shown in the yellow circle in the picture below:

steve_con_92.jpg

By default, the aperture is at minimum. The camera moves the lever from this position to full open (and anywhere between) as needed. You should gently move the lever to the other end of its travel to open the aperture to maximum. Point the lens away from a light source but preferably at a light colored background. Look through the lens. There should be no obstructions and be clear. Next, look at a dark colored background to find the same results. If you want, you can even allow sunlight to shine through the lens onto a sheet of paper (like a magnifying glass). The result should be a bright circle with no obstructions. Obstructions in the lens will prevent the meter in the camera from getting accurate information about the scene and if significant enough, prevent viewing through the viewfinder.

You may wish to have the camera & lens professionally cleaned and serviced to repair a mirror or lens issue.

If this was helpful, please rate it as such. Good luck!

Nikon F100 does not advance film to start of roll,


Jim, it really sounds like one of threethings. Either will require a repair shop.
1. the film sensor is not recognizing film in the film chamber, or film across the back, therefore not telling the advance motor to advance film...
2. The film advance motor itself needs replaced.
3. The rear door latch switch needs replaced.
Since everything else seems to do OK, I doubt the main computer board is bad.

40D turns off as I press shutter button


The shutter mechanism had to be replaced. I've heard that this is a typical 40D problem, due to a shutter design flaw. They say that it has been fixed on replacement shutters.

50mm C lens issue


From your description, Yes. All RB67 lenses have common problems, usually sticky blades. Since there are 2 sets of blades, (shutter and aperture), the shutter blades may be contaminated with oil/debris

D50 won't take a picture!


I was having the same problem.. And since I could not afford to take it to the shop, I tried everything I could think of...
Then I fixed it!!
It seems that the slide door behind the shutter was stuck for some reason... If you remove the lens.. (make sure the camera is in manual mode)... snap a shot so the shutter is up.. then gently slide the panel in the back down....
Once I did that.. the camera was working again.... Hope this easy solution works for you guys....

Aperture priority not working...HELP!!


Hey Mike, This is an easy one. With the battery grip attached, you can only have either Shutter Priority or Aperture Priority work properly. You can change it with the custom function settings of the camera. So you can change it to work with Aperture Priority if you use that more so then shutter priority won't work. Brandon
