There wasn't much to the instruction leaflet and it was in multiple languages as well.

Camera off and set manual focus when changing lens then put back to auto focus.

To engage macro mode, zoom out to 300mm. You should be able to zoom between 200mm and 300mm while in macro mode but it doesn't make much difference.

In macro mode you're about 95cm from the subject! I found setting Continuous auto focus mode allowed me to rock back and forth while framing yet keep in focus.

Thanks Bob,

What is the significance of this " Camera off and set manual focus when changing lens then put back to auto focus. Can you help with aperture ring base of lens.

Have you had success with macro settings

The camera should be turned off whenever changing lenses.

This is a "screwdriver" lens. The autofocus motor in the camera body connects to the focus mechanism in the lens through a screwdriver like pin on the lower right side of the lens mount when seen from the front. The AF/manual switch on the left side of the lens mount engages and disengages the pin from the lens. You want this to be disengaged to avoid straining the mechanism by turning it from the focus ring. Nikkor AF-S and Sigma HSM lenses have a built in motor so this doesn't apply.

You may have to turn the focus ring to get out of macro mode. You will have to be in manual focus mode to do this.

The aperture ring should be set to f/22. It is highlighted in orange on my lens. To the right about a quarter way around there is a slide lock. This should be engaged by sliding towards the camera to prevent the ring from moving. The camera will lock and post an "FEE" error if the ring isn't locked at f/22.

I've had the best results setting the lens between f/11 and f/16. The subject will be far enough from the camera, 95cm or more, that I can use the built in or external flash for illumination. I usually use M mode, 1/250, f/16, spot metering and flash WB in these cases. These settings usually get me nice dark backgrounds that make the subject stand out. The flash means not worrying about camera shake!

At 300mm you are getting into long telephoto territory so you have to keep the shutter speed high even if it means bumping up the ISO. I was finally satisfied when I shot at 1/500 and kept the aperture closer to f/11. I also usually shoot from a monopod to stabilize the camera better.

I use a Manfrotto model 681, with the model 234 monopod head, and the model 323 quick release plate. The QR plate simplifies walking around without having the camera attached to the monopod. The head allows the camera to rotate between portrait and landscape easlily. The camera can also be rotated on the head to tilt back and forth.

The monopod allows more stability when shooting but isn't as clumsy as a full tripod. I've even wedged it up against walls and fences to simulate a tripod!
