Aperture not going below 6

Hi,
When I extend the lens at all, I cannot change the aperture on this lens to go below 6. Is this a problem with the camera or a setting I have to change?

There is no problem. The lens is f/3.5-6.3. That means that at 200mm the maximum aperture is f/6.3. At long focal lengths you will not be able to open up beyond f/6 or so. At the short end, at 18mm the maximum aperture is f/3.5.

How do I switch to an aperture higher than f/32 on my nikon d3000?


Yes. Just lock the lens aperture ring at its smallest setting (largest f/number). If you need to change the aperture, change it from the camera body by turning the command dial, the same way as with a lens without an aperture ring.

Hi, I have a Nikon D60. Somehow I locked aperture at highest number. Even with Manual setting, it does not let me change aperture! Please help


The lens is supposed to be locked at its smallest setting (largest f/number). You can control the aperture from the camera body, the same was as on a lens without an aperture ring. For example, in aperture priority mode (A), simply turn the command dial. In manual mode (M), hold down the exposure compensation button while turning the command dial.

That was for a lens with the electronics to communicate with the camera. If you have a purely mechanical lens, you must shoot in manual mode and control the aperture by turning the ring on the lens. There should be a small orange slide near the aperture ring, Slide it toward the front of the lens to unlock the ring.

If you need more help, please feel free to reply to this post. Please specify the lens when you do.

Message: Lock lens aperture ring at minimum aperture (largest f-number) I think I'm doing this but the message won't go away and the camera won't work.


You must lock the aperture ring to f/22, so the camera can engage the aperture adjustment lever on the lens. Then, you can change the aperture with the command wheel.

When you change the aperture with the command wheel the aperture ring on the lens doesn't move when the camera actually adjusts the lens aperture.

Take the lens off and locate the aperture adjustment lever on the lens mount.

Unfortunately, this won't work with older AF lenses. So if you are using an older lens, the only thing you can do is change the camera setting to M (Manual) to adjust the aperture on the lens yourself.

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).

Hi, When i turn on my camera attached with my 18-135mm lens, it says F-- . I've tried change with another lens, then it became normal and it seems like no problem at all. What is the problem actually...


Hi Norhid. There may be no problem at all. If your camera body is in shutter priority and your lense's aperture ring is turned to any setting besides its widest, the body and lense will not synch. See if you can find an orange aperture setting on your lense's ring, and a white dot on the lense alongside the aperture ring. Mount your 18-135 and line up the orange aperture number with the white dot and see if everything works. If that doesn't help, try switching the exposure modes you're shooting in. Hope this helps.

Hi- purchased the Extender EF 2X II; it seems fine with my fixed focus 300mm, but the auto-focus doesn't operate with my 70-200mm EF IS USM zoom, in any mode. Any suggestions? Thanks G


You haven't stated which body you have but the AF will not work with the extender if the effective lens aperture is too low (remember that a 2x extender doubles the focal length but halves the effective aperture).

Canon's own website states: "Autofocusing does not operate if the effective maximum aperture is greater than f/5.6 (greater than f/8 on the EOS 1V and EOS 3)."

Lens won't extend when switched on


Hi,
I would like to know what mode are you clicking these photos in.. because overexposure is due to either slow shutter speeds or large aperture. Try setting the camre mode according to the surrounding light conditions.. for example, no need of flash when you are clicking pictures in broad day light, instead of setting the camera on Auto mode, try using Portrait mode for short distance (5 to 6 meters away) objects etc..
Let me know if that fixes the issue.

And important .. Do not forget to rate the solution :D

Thanka and Regards,
Srinivas

Canon Extender EX 1.4x ii not autofocussing


The EOS 40D only use auto focus up to aperture 5.6. Only the 1-series use auto focus up to aperture 8. The adapter adds 1 stop to the lens aperture. Since the 100-400 is a 4.5-5.6, the aperture range with the extender mounted will be 6.3-8.
There is a work around though. Just place a thin strip of insulating tape over the three pins on the lefthand side (lens side of the extender). No damage will occur to the camera or teleconverter.

What does it mean when FEE is in the view finder


FEE means that your lens is not set to the smallest aperture setting. If you are using your camera's auto-focus mode, the lens must be set to the smallest aperture setting which, on your lens, is probably f22 (the smallest aperture is the largest number). Once you set the lens aperture, you should slide the aperture lock to the locked position. The aperture lock is located just right of your largest setting f3.5. This slider should line up with the orange line. To verify that the latch is engaged, try to change the aperture by rotating the aperture ring. In the locked position, the ring will not turn.
