Nikon d40, Sigma Macro 105 mm and remote control compatibility

[Ken1974]

I have just purchased a Sigma 105 Macro lens which has manual and autofocus modes. The D40 only supports manual focus which I knew in advance. However, the Nikon remote ML-L3 does not work with that lens even on manual focus mode.

Any suggestions?

The receiver on the camera must see the transmitter in your hand. It must point at the camera from the front, and the distance between the camera and transmitter must be short.

I'll keep an eye on this thread and let us know if you get this resolved or not. If not, I can post it over in

Not that people here don't, but that site has forums for each major camera make and some real brand experts haunt it.
Unless you want to sign up and post it there.

Several people posted with suggestions: make sure you are in remote mode, also not remote delay mode unless you want that, make sure you have the remote pointing the correct direction (plastic lens facing camera), facing the correct side of the camera (front) and within distance. I'm assuming you know all that.

One person asked if this lens is AF-S compatible. I'm inferring from this question that if it is not, then this would lock up the shutter. Not having tried this, I would assume if it locks in remote it locks in hand use, and similarly if it works in hand mode it would work in remote mode.

Ken,
I'd also try the process of elimination...
-Start by checking the things Jon brought up.
-Does the remote work with other lenses attached t the camera?
-Does the camera fire with the Sigma lens on it when you depress the shutter release?
-Check the custom settings for AF...is the camera programmed to only shoot when in focus? If so, even in manual,does the viewfinder give you the green go light when you have focused on the subject?
-Even he obvious ones...is there a card in the camera?
When you have narrowed it down...you should find the answer to your problem.
I could not find anything in a search about the remote not working with third party lenses attached.

my first thought is "does the camera recognize the subject as being in focus"?
is the little green light bottom left of viewfinder lit? even in manual focus it will still meter light and focus
if not this is prob why it's not firing..
(my wife has the same camera, but has the 70-300 macro non-HSM...have run into this situation a couple of times before)
