Question about Nikon D40x Digital Camera

1 Answer

Flashing red square area in viewfinder.

I have a Nikon D40 with the original lense, a AF-S NIKKOR 18-55.
I also have a AF-S NIKKOR 55-200 lense.

The 200 lense works fine, and auto focus works with the current camera settings.

However, when I put the 18-55 back on, the focus area in the viewfinder flashes red instead of black when it is finding the focus area.

Did I adjust a setting by mistake???

No, I don't think so, there could be differences between the Auto and the P setting. But the red flashing is where your camera is currently focusing on. It's possible that the black was indicating the focus box, but it was not latched on to something with complete focus, which then is indicated by the red flashing. Check this link to read up further on this. I may not have pinpointed it exactly, because I have a D70s, but that's what I found so far. You'll maybe have to reset everything and see if it's still there, otherwise, it's a setting. =)

18-55mm lens won't zoom

DON'T TRY TO FIX THIS YOURSELF! You will only add to the damage. If your lens is in warranty, contact Nikon for instructions to get it repaired. If it is out of warranty, I would either pay Nikon for the repair or take it to a camera repair man.

Nikkor lense

You need AF-S or AF-I Lenses. These have the autofocus motor built in to the lense. The D40 and D40x does not have an autofocus motor in the camera body itself, while the D80, D300, D3 Etc to have the motor in the camera. You can use most old lenses on your D40x, but you will have to focus them manually.

See Ken Rockwells page for a lot of D40 / D40x info

Tamron 28-300mm Model 185D Auto Zoom on Nikon d40

Autofocus function on the D40 only supports lenses with the
AF-S feature, which have an autofocus motor built into the lens,
instead of using an autofocus motor drive built into the camera.

The Tamron lens you have, does not have a built in motor and
the autofocus function relies on the motor drive in the camera.

It will not work with the D40 or D60, but it will work with other
Nikon digital SLRs, such as the D80. Need to get an AF-S
type lens or upgrade to different Nikon digital SLR. Unless
you do this, you will have to manually focus the Tamron lens.

All of the Nikon DX (for digital) series lenses are also AF-S
type, so they will work with the D40, which is designed as
an entry level digital SLR, therefore it is intended primarily
for use with DX lenses, which are typically sold in a kit with
the D40. Most common one is Nikkor 18-55mm DX AF-S.

Other Nikon AF-S lenses made for film cameras (FX type)
will also work with the D40, but these tend to be expensive
professional models. DX series lenses tend to be more
affordable. You might consider the 18-200mm DX AF-S
as an alternative to the Tamron, but these are not cheap.
