Hi .
I'm Jan, a new entry level photographer.
I need to know how to How to focus on flowers? because I have tried to take a macro photo but not  sharp of all.
Please give me some comment of my sample.

AF-S DX Micro NIKKOR 40mm f/2.8G
A 1/3  f 5.6  ISO 100   manual focus
no process on computer (resize only)
Thank you very much.

I am far from a macro expert, but I dabble in it. A couple notes on pure photography principals: 

1. Are you hand-holding? If so, 1/3 of a second is way to slow for shutter speed. The rule of thumb I've always heard is 1/50 or faster for hand-holding. Certainly some may have steadier hands to go a tad slower. If using a tripod, this won't be an issue unless outside and wind is moving the flower. At 1/3 everything needs to be very still. 

2. If you're manual focusing, it's certainly possible you're just not getting it in perfect focus. 

3. With a 40mm, I'm guessing you're very close to the flower to shoot this unless you cropped a lot. If so, keep in mind depth of field. Shooting f/5.6 very close to the subject is not going to leave the entire flower sharp. That's not a bad thing - depends what you're looking for. If you want an artistic look with only part of the flower sharp, that's fine. If you want the whole flower in focus, you're going to have to go with a smaller aperture (larger number) to get a larger depth of field. Not sure what that lens allows, but try all the way up to f/22 (for example) in increments to see the results and pick what look you like most. Of course, to let in less light and get larger and also use a higher shutter speed you're also going to increase that ISO quite a bit (or have more available light). 

It could be a combination of all 3 of the above. 

Good luck!

Hi Scott,

Thank you for your kind comment.
1. Of course! I shot this photo with a tripod but still have a little wind.
2. Manual focusing.
3. At first I have no idea about f number so I think f/5.6 should enough and also set A mode (shutter speed calculate by camera).

I once again thank you very much for the comment.

I often take pictures of insects & flowers.

Anyone using a compact camera should press the close focus button so that the cameras auto-focus focuses only in the middle.

For hand holding, the shutter speed should be the same as the lens's focal length or faster, ie 50mm 50th of a second or faster, 100mm 100 of a second or faster,

Aperture gives more depth of field if smaller ie F16, F22, for a shallow depth of field try a wide aperture, ie F4, F5.6.

You could try setting your camera to Manual mode but the ISO to auto. Bear in mind higher ISO values give you more noise, so keep an eye on how high the ISO goes. With a higher ISO you will get more noise but sharper pictures. Bear in mind that if and when you print your picture some of that noise will disappear. Newer cameras generally produce less noisy images than older ones, as do dearer cameras compared to cheaper ones. Noise can also be reduced in post processing, though it also reduces sharpness. Even with the best cameras it is all about balance & compromise.
