There is a locking ring you have to remove and then the front optic may fall out if it sticks you may need to heat up the barrel that might work

Sigma lens error message aperture ring


Does this only happen with this lens? If other lenses work OK, then the problem is in the lens. If it happens with all lenses then it is in the body.

Try cleaning the contacts on the back of the lens and in the body mirror box with a Q-tip lightly saturated with alcohol.

How old is your lens? It may have a conflict with the newer camera body. Did it work right before?

I have quite a lot of fungus inside my sigma mirror ultra lens, the front lenses were easy to get out and polish but I am concerned about dismantling the smaller rear lenses. Are there any complications to...


Holy Smokes, well if I were you right now I'd put it back together and send it to Sigma for repair cause you dismantle a lens like that there is no way you are going to align those lens elements without the proper equipment.

Using anything more then lens cleaner for camera optics will in fact remove the coating from the lens.

What you have isn't like the lenses from a "View" camera where it was possible to remove one lens group and replace with another but, those lenses were made and used 70 years ago.

Lens technology has changed a bit since then.

I had a manual focus Nikon F2.8 lens one time that had a coating separation on the front element that caused some wicked flare. I took eye glass cleaner and Windex to it to remove the rest of the coating so I could continue the shoot. I then sent the lens to Nikon for repair.

Best of luck with that one

Error 01


Error 01 is about the communication of the LENS with the camera. Please try to re-attach it and make sure it is correctly fitted. Also you can remove the lens, start cleaning the contacts, put it back in place again and then test.

Good luck!

The mirror on a DSLR should never be touched except by a qualified service technician! Not only do you risk removing the finish ( unlike a regular mirror, it is on the front of the glass, not the back) but the delicate placement of the mirror and it's lifting mechanism can be misaligned by any pressure.

Have you tried formating the memory card? R07 means it has 7 shots in internal memory. Since you have already pressed the reset through the small hole in the front, if formatting the card does not work, try downloading the latest firmware from Nikon and installing it.

when you take the lens off .. there is a mirror and the CCD array ... those can get dusty or if anyone smokes around the camera then that gets on these parts .. you can dust the mirror and CCD behind with a soft clean camel hair brush but a good cleaning should be done by a pro .. thats a "front surface mirror" .. that is, the mirror surface is not protected by glass the way mirrors normally are .. so it scratches very easy ... there are special techniques for cleaning that must be learned before attempting a deep cleaning .. the back side of the lens also may have a smoky coating that has to be cleaned .. again a pro is best but you can use a lens cleaning cloth and solution .. (dont spray the solution into the lens . only on the cloth .. with every thing clean your camera should be back to like new performance ..

Wont take a picture displays error 99


Other than sending the camera to the shop to get replacement, you can do this method to temporarily solve the problem. Set the camera to P mode, go for Sensor Cleaning Mode, Manual Cleaning, and clean now... You will then hear the mirror lock and followed by ERR99! All you have to do now is to shut off the camera, take off the battery and waith few seconds. Reinstal the battery and immediately you'll hear the mirror resetting itself. The camera should be working just fine for now until you shut it off next. I suspect, this error are linked to the mirror or sensor lock up thingy....

Err 99 appears on lcd after every 5 clicks in canon eos 30D


the lens contacts are dirty - get a pencil with an eraser on the end, just a regular old pencil with a red rubber eraser. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them. Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly. I've used a lens cloth and dabbed at the contacts rather than blow them so as not to blow the erasings inside the camera. Let me know how it works for you!

The secondary small mirror that guides the light from the lens to the sensors ( sensors sit at the bottom of the mirror box , underneeth the main mirror ) may be out of position. To check : take lens off and gently lift the main mirror half way up ( pushing up ) and see if the secondary mirror is dangling ( which it should not be doing ). Correct 1) reingage spring 2) reingage hinge.
