    Thanks for that ... I have spoken to a friend who repairs RB's and he recommended a CLA also which is likely all it needs.

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

FEE keeps popping up on my camera what does it mean

You're using a lens with an aperture ring. Turn it to its smallest setting (largest f/number). You can control the aperture from the camera body, the same way you do with a lens without an aperture ring.

What does fEe mean on Nikon 35 mm camera

This means that the lens doesn't have its aperture ring set to its smallest opening.
Turn the aperture ring to its smallest opening (largest f/fnumber) and lock it if the lens has an aperture ring lock. You control the aperture from the body, the same way as with a lens without an aperture ring.

What does fee mean on a 35mm camera

If it's on an SLR then it means the lens is not set to its minimum aperture. Turn the aperture ring on the lens to its smallest opening (largest f/number) and lock it if it has a lock. You control the lens aperture from the body, exactly the same way as on a lens without an aperture ring.

Manual Canon 50mm FD lense will not focus!?

In that case the linkage between the movable parts of the lens group and the focussing ring has failed.

What follows applies to most lenses; I have a Canon 50mm FD to hand but as it works perfectly I've not needed to dismantle it so far but have repaired many others.

When you turn the focus ring there are usually two pegs which engage into helical slots cut into the focussing ring, these are hidden within the lens and you won't see them unless the lens is dismantled. The pegs are usually rounded to make the passage along the helical slot even smoother and each one is fixed to the inner lens barrel by a screw. On older lenses, the grease inside can dry out a bit, especially if the lens remains unused, when this happens the pegs may either shear off or simply become unscrewed and drop off. The gummy grease may hold them so you won't always hear a rattling part inside.

To fix it, you carefully dismantle the lens to the minimum extent you can get away with. You'll need good light, patience and a set of good quality crosshead precision screwdrivers. Normally you start with the screws on the mounting flange and watch out for small springs and detent balls which tend to escape to freedom never to be seen again. Some of the screws are usually hidden beneath the rubber grip on the focussing ring, and you remove this to check by carefully lifting an edge and then rolling it back over itself. It may need re-gluing afterwards. Clean out dried grease as you go and apply a small amount of thick grease to replace it on reassembly: less is far better than too much! Some of the screws may need thread lock applied to them when they go back in, but you're better off leaving this as your first time lens repair usually has to come apart again due to an error in reassembly.

Be prepared to ruin this lens as it's your first lens repair. The good news is that auction websites have plenty of other cheaply and in full working order, just make sure to ask if the iris (aperture) works smoothly and snappily and that the lens does not have the dreaded lens fungus on the glass elements (a patchy white haze). You can also usually get these lenses for free on Yahoo FreeCycle and a camera body and other goodies normally come as part of the offer. FreeCycle is how I've collected various Nikons, Canons and Pentax SLRs and lenses over the last year to add to my existing Olympus gear.

I hope that I've helped you, if so please return the favour by rating my answer.

Instruction manual for settings on a Nikon F2?

Set the film speed with the dial on top of the Photomic unit. Lift the chrome ring and turn so that the film speed is next to the little red arrow.
Yes, the aperture is set by the lens ring. And if you have one of the older finders which uses the prong meter connection, whenever you mount a lens you must turn the aperture ring all the way to the highest number, then back to the lowest number. For old-timers, this is known as the "Nikon twist". It tells the meter system what the widest aperture of the lens is so that it can measure light properly at full aperture.
Yes, the shutter speed is set by the dial on top. The Photomic meter sits on top of it, so you read the shutter speed from the scale on the side of the Photomic dial by the mark on the back.
The other buttons on the front are the lens release button (left side as you hold the camera), DOF preview (button just under shutter release), mirror lock-up (lever ring around DOF button) and self-timer (long lever at bottom).
The T-L ring serves to protect the shutter release from accidental push. If you lift the ring and turn the mark to L, the shutter release is Locked. If you lift and turn to T, it prepares the shutter for Time operation, where the shutter remains open when released without holding the button down as you do at the B speed setting.

Finally, the most help: you can download the manual for free (donation requested, and worth it) at

Olympus OM-4 Shutter Release Button Stuck

  1. First ry to reset the Self Timer lever.
  2. Try to change the aperture.
  3. Try to unscrew the lens
  4. Open the film chamber slightly (just to loosen any lever that has got stuck)
One of these operations would dislodge any normal lever jam. If these fail to solve the problem, take it to a repair shop.

Shutter stays closed on bronica 645 etr medium format

Have the electronic shutter checked by a repair shop. Sounds like your Seiko electronic shutter has died or there's a short somewhere between shutter and lens. Hope this helps.

Aperture diaphram on mamiya secor lens 80mm f/2.8

The lens has a lever marked A/M near the aperture ring. If the lever is in the 'A' position, the lens will stay wide open until you trip the control lever at the back of the lens next to the rear optics. In the 'M' setting, you can see the aperture move as you change the f-stop setting on the ring. Set the lens to anything but wide open and move the control lever with your finger. You should see that aperture move.

Problem with nikon n55

What lens are you using? Do you have other lenses you can try?

The F-- indicates that the camera and the lens are not communicating. There are several reasons for this:

1. The lens is not electronic. All lenses before the advent of autofocus fall into this category, as well as some of the newer ones. The only way these lenses can be used is in Manual (M) mode, without any assistance from the camera's light meter.

2. The lens has a locking aperture ring. In this case turn the aperture ring to the smallest aperture (largest f/number) and lock it. You control the aperture via the command dial on the camera body.

3. The contacts are dirty. Remove the lens, clean the contacts on the back of the lens and on the mount, then reattach the lens and see what happens.

4. The lens and/or camera body needs service.
