Question about Pentax ME Super 35mm SLR Camera

1 Answer

My Pentax Camera Light Meter is not registering changes made to the Aperture Ring.

My camera works fine. All the LED lights light up and the shutters works fine. The main problem is when ever I take a reading, and then change the aperture it still suggest the same shutter speed no matter what f-stop I use.

Example: If I keep the lens at a f-stop of f2 and says 1/500th of a second then change it to f22. It still says 1/500th of a second without saying its under or over exposed.

Take lens off to check the lens/light-meter coupler situated inside the lens mount at the top part of the mount at 'one o'clock' . First see if it moves freely ,clock wise. Then -with the lens off- look through the view finder while you activate the coupler : moving it should make the l.meter lights move up and down.
If you are not getting any joy the connection between the coupler and the board needs re-soldering ( dry joints ) : remove top cover and resolder two blue wires on left hand side of the board . This should do the trick.

First, check if you're taking the lens cap off. If you're taking it off, then check your exposure. See if your light meter responds to changes in illumination. If everything seems fine, then check if the aperture of the lens works as intended. Then, without a lens nor film in bulb mode, check for the mirror and shutter to work properly. If the light meter, aperture, mirror or shutter seem to flaw, then get your camera serviced by an experienced camera repair technician.

I would like to know if a 24mm Nikon f2.8 Ai Manual Focus Lens will work on a Nikon N75 SLR Camera

Yes and no. It will fit and you can take pictures with it. You'll have to focus manually, of course, and you won't get any exposure help from the camera's light meter. You'll have to use the camera in the Manual exposure mode, setting the shutter speed on the camera body and the aperture by turning the ring on the lens and, as I said earlier, without any help from the camera's light meter.

I'm doing a project for school and i need to change the aperture for different photos. But my camera refuses to take the photo on any other aperture. Why is there an aperture adjuster if you can't use it....

It depends on the lens.

If you're using a lens with an aperture ring, simply set the exposure mode to Manual or Aperture priority and change the aperture by turning the aperture ring on the lens. In Aperture priority the camera will set the shutter speed appropriately, in Manual you have to determine the appropriate shutter speed. If you want to use such a lens in Shutter priority or one of the Program modes, you must set the aperture to its smallest setting (largest f/number) and lock it.

If you're using a lens without an aperture ring then it's a bit harder. You can only use the camera in Shutter priority or one of the Program modes. You turn the command dial on the camera to change the exposure, and the aperture will change. If you want to use an exposure different than what the meter suggests, you can adjust it by using either exposure compensation or changing the ISO setting (or both).

X-370S 35mm SLR Camera: what is the best aperture, shutter speed and iso f...

Your camera light meter should tell you, but in case it doesn't work then all you need to remember is the "Sunny 16 Rule". Basically, on a bright day and with the lens aperture set to f16 you set the reciprocal of the film speed.

So with ISO 100 film the reciprocal is 1/100, or 1/100th of a second. Your camera shutter speed dial doesn't have that, but it does have 1/125th which is close enough.

Once you have the exposure set for f16 then if you adjust the aperture you simply adjust the shutter speed to match. So if you decide to set f11 that allows twice as much light onto the film so to compensate you reset the shutter speed to 1/250th of a second to halve the light coming in. As twice the light coming in through the aperture is compensated for by halving the light coming in via the shutter, the exposure remains the same.

Although this works for a sunny day, you just guess based on experience other lighting conditions. So if it's bright but overcast then you can leave things as they are, but if it's dull and overcast allow one extra stop of exposure by opening the aperture by one setting or by doubling the time that the shutter remains open. So from the starting point of f16 at 1/125 (as above), on a dull cloudy day you'd either set f11 OR 1/60. If you set f11 AND 1/60 then you'll be allowing not just twice as much light in but three times as much.

Hope this helps, if so please take a moment to rate my answer. If it's too complicated then please add a comment and I'll re-explain in even simpler terms.

Nikon f3 hp light meter wont work

I'm interested in this as well. Just installed fresh batteries, light meter says 1/80 in all shutter settings faster than 1/60 (otherwise it shows the correct setting). Since 1/80 is the flash sync speed, it may be that the camera thinks there's a flash attached. But it is not...
Strange thing is that one time (I tried a couple of times today) the light meter worked correctly; it showed other timings and they changed as I turned the aperture ring...

Light meter or not on Maxxum 4

Yes, it has program, aperture priority, shutter priority and manual modes.The aperture and shutter settings should be visible on both the right hand top plate LCD panel, and also in an illuminate LED panel below the image in the viewfinder.

From memory (and I might be wrong) the Dynax 4 (Maxxum 4 in North America, Dynax 3 in Asia Pacific) light meter simply indicated a plus or minus symbol to indicate over or under exposure for the selected combination of shutter and aperture. The viewfinder display would have a steady dot to confirm confirm focus follwed by the chosen shutter speed and aperture setting.

I cannot find a link to anything other than a German manual, but the diagrams and a bit of mental application will go a long way if you don't understand German.

Note that if your camera's electronics have failed then there's nothing you can realistically do other than to replace it. Spares are not available and as a consumer level model it was never really intended to be serviced or repaired.

How to KNOW the light is right 4 an Olympus OM20 Manual camera?

OM-20 was basically a upgraded OM-10 with the manual adapter built in and a number of other refinements.

The viewfinder has LED's to show the shutter speed recommended by the camera's lightmeter for the ISO and aperture selected. It also has an exposure compensation indicator (the +/- symbol) and an indicator for flash ready which doubles up as a post-exposure flash confirmation. There is also the indicator lamp to show manual mode has been selected. OM-10 lacks the manual mode lamp and the +/- indicator.

Like the OM-10, the OM-20 is primarily an aperture priority automatic camera. In this mode you set the ISO film speed, choose which aperture you wish to use (with the ability to use the lens depth of field preview button) and then the camera selects the correct shutter speed. The +/- exposure compensation control allows the user to tell the camera to modify the recommended shutter speed by up to two stops either way.

In manual mode, there is no manual metering. The light meter behaves exactly as it does in aperture priority mode and the viewfinder shows the recommended shutter speed and not the manually selected one. Correct metering is therefore a case of adjusting the aperture first, and then choosing the correct shutter speed indicated in the viewfinder. If the user then decides to select a different shutter speed, then the aperture ring must be adjusted to maintain the correct exposure. For example the aperture is set to f8 and the camera recommends 1/60th of a second. The user decides that a faster shutter speed is required and chooses 1/250th, but the viewfinder remains showing 1/60th. In order to keep the same exposure value the user must open the aperture by two full stops to f4. The camera's light meter will detect the new aperture setting and providing the light on the object is unchanged the viewfinder shutter speed display should now show 1/250th as well to confirm the correct adjustment. Alternatively, the user can choose the shutter speed first by looking at what has been set on the control ring (or by turning the ring to the end of its travel and then counting the clicks from there as all experienced OM users do) and then turning the aperture ring until the shutter speed shown in the viewfinder matches what's been manually set.

It all sounds clumsy and complex but is done far more quickly than I've taken to type this and becomes second nature.

Aperture priority metering is selected on the camera by choosing AUTO on the mode selecter. In this mode the shutter speed ring has no effect and the viewfinder always displays the automatically selected shutter speed.

Light meter

Yes, the Pentax ME Super has a built-in light meter. It is used by the ME Super in order to determine the correct exposure settings when the camera is used in the "A" (Autoexposure) & "AV" (Aperture-priority) exposure modes.

I don't mean to insult you, but have you tried new batteries?

Sometimes the meter fails when the batteries don't have enough juice.

Take care & Happy Imaging!

Yes, on the camera body, you have to remove the lens. The ring sits outside the metal mount for the lens.

Light meter failure and shutter button sticking

Set your camera to B and release the shutter ( camera will work in this mode without batteries ) if you can wind ok and release shutter fine then all you need is new batteries. If however your camera is not working when set to B then it is either the shutter or the transport mechanism that need looking at. From experience ( have repaired 100s of Me-supers ) it is likely that your shutter needs attention : rubber components ( and foam rubber ) inside the shutter ( and the mirror box locking mechanism especially ) have perished and need replacing.
