I'm using this on a D3200 and I can't change the aperture. I get an error message: must lock lens at minimum setting. Why??

On the lense itself, it must be set to f22, then lock it (its a tiny notch thing you push up).

Since this lens is a little more basic than the other lenses, you have to lock the aperture ring in where the red dot is on the lens.. Once it's locked it you can control the aperture through the camera like normal.

Your D3200 controls the aperture through software. I don't know exactly were, but in the same place where you control your aperture while using a 18-55mm. So you must set your lens aperture at minimum aperture, which i dont remember exactly, but i believe it is f/22, and then you have to lock it (there is two red dots, put then together).

Hey Aaron, common mistake. What you need to do is set the actual aperture on the lens ring to 22 and the lock it on that value so that the little red line aligns with the 22. This happens because you are using an older non focusing lens on a newer body. Problem solved. Have fun, that is a fantastic lens.

Im not a photograpy guru. But I use mine with a nikon 35 mm f/1.8 dx. Change to aperture priority and adjust the ISO. I take pics in the house all the time. The flash doesnt go off and the pics are really good. The house is kind of dark. Havent tried in wedding or convention setting. I love this camera. You just need to buy the right lens for the applications you want

I found it. The menu has a setting for a lens that has an aperture ring. So all I did was change the setting to "permitted" and it worked. So thanks to K. Johnson for the response and I will now put this forum to rest. What a great little camera, the Pentax Kx! And I just found out that it takes multiple exposure pictures; how much fun is that?

Mine are same problem on my Nikon D5300, they won't lock and the camera reports no lens attached. Wish I hadn't waited 2 months to try them....

No. The aperture is adjustable in all "creative modes." That is, A, S, M and P settings. You would "force" f/2.8, for example, if you locked ISO at 100 and then selected a fast shutter speed - in other words proper exposure would required f/2.8. In the Scene modes, you have far less control. Put the camera into Auto ISO and see if you still have this issue.

None of my lenses have an aperture ring; aperture and aperture priority is controlled by the camera body. I own the 5300, not the D5100, but aperture priority is a pretty basic function, so I am sure the function exists in that camera body.

I have Canon D60 and T3i and this lens is fantastic on both at all settings. I would contact sigma and talk to them about it.

There is a white square on the camera where you attach the lens - line it up with the white square on the lens -then twist to lock-hope this helps

The SETTING should stay the same. I'm checking...In the Aperture mode, setting to f/2.8 and rotating the zoom full out and back, the F/2.8 stays the same on the screen. On my Nikon D7000 the only way to control the ap...unless I've missed something, is in the A mode. Changing the mode dial displays a different ap biased on other factors. Even then, rotating the zoom does not change the displayed ap setting. Ie if rotating the mode from A mode where you have set the ap to say f3, to M or S, the ap may stay or move to another value if needed. At this point, whatever the value is displayed, rotating the zoom out or in does not change the f value. The SETTING should stay the same.

I also had trouble at first. There is a metal tab on the interior of the adapter that you have to push in to get it to "lock." You may need to use a small screwdriver to hold it down while placing it onto the lens. Once it's on you'll know.

No, the aperture is not locked in other shooting modes. The aperture ring may stay on the f/2.8 position, but the actual aperture will vary according to other settings such as shutter speed and ISO, and the lighting conditions. Try aiming at a bright subject and look for the aperture value that appears on the camera's display.

This doesn't have adjustable aperture blades. thus the aperture is at max. OM lenses themselves have on-lens adjustable aperture.

The problem I have is that the Fotodiox lens Adapter is locked onto my Canon lens and i can't remove it. I would appreciate some instruction on how to resolve this problem. I can't used my lens on my canon camera.

TMP, I just tried this on my lens and got the same error. I have never needed to adjust aperture manually and would rather have the camera do this anyway. Your camera has an internal motor for auto aperture (AE) Your lens is a "D" lens (the G lens doesn't have a ring) which can be used on camera's that don't have a motor like the D40. You need to lock it, forget about it and just adjust aperture using the camera's wheel. See here, hope this helps? http://support.nikonusa.com/app/answers/detail/a_id/2605/~/what-does-the-fee-or-f---error-message-displayed-on-an-slr-camera-mean%3F

This lens is manual focus and manual aperture. So it won't AF or automatically adjust the aperture. It works in full manual mode very nicely but that may not be what you want to do.

Here's how a D lens works on your camera: you keep the lens locked at the largest aperture number on the aperture ring. You do not go off this locked setting or you'll get an FEE error. You change all your f stops from f/4 to f/32 through your camera body only.

i believe this is a manual only lens. change the aperture by turning the aperture dial on the lens itself.
