How does one set the D50 to focus on infinity, such as the blue sky or night sky?

The AF-lock button seems to require that it be held down, so I don't think I can focus on an object and then recompose. Not to mention, that would not help in trying to take fireworks.

Any advice or explanation on this?

Thank you for reading.

Maybe its just my lens, but the Kit lens is absolutely HORRIBLE for manual focusing.

To use the manual focus you need to Flick the little switch on the lens from A to M, and then you can rotate the front element (where you screw on the filter) Manually.

The problem is It has a close range, medium, far and then A horrible point PAST infinity where EVERYTHING is blurry.
I really hope its just my lens that has that, Because it makes finding infinity almost impossible. Not to mention that any bumping of the lens or camera will cause the focus to shift ever soo slightly. After a few bumps or jerks of the camera you will be completely out of focus again, and need to take the time to Manually focus to that hard to pinpoint infinity focus.

Its EXTREMELY frustrating for taking Infrared Shots because to manually focus you need to take off the IR filter.

I also have the Nikkor 50mm F1.8, And this is how a lens SHOULD manual focus, You can turn the focus ring (Which is sepperate from the part where you screw on your filters) And its End point is INFINITY, theres no stupid out of focus area, its easy to turn and you can't really bump it and unfocus.

Which lense(s) you using?

Why not try Manual Focusing (MF), if your lenses support it?

I have the AF-S 18-55mm DX kit lens and an AF 70-300mm G lens.

Only the kit lens has an A/M swtich.

What does the A-M switch on the camera body do? Am I supposed to set both the 18-55 and camera body to M to get manual?

Simply put, the A/M switches, if any either on the lense or the body, have to be ***in_sync***

i.e. either both A or both M.

In your case of 70-300, I think just turn the D50 body to M is sufficient.

Actually the Kit lens only requires you to set the Lens switch to M, you can leave the body in AF, and it works fine.

So what would happen if M on lense, but A on body?

Can it both AF (by the body), and MF (by focus ring on the lense) at the same time?

That would be a nice feature

Try it! If you put the lens on MF while the body is AF, you get MF. For lenses with an MF switch I think you have to use the lens switch to get MF (true on my kit lens and 60mm micro anyway).
