yes I use the diffuser .......

I have both bad and good news for you.

First the bad news. Even with a DS-200 you will have to increase the ISO in-order to shoot at F/22. At least to ISO200. And probably ISO400 if you are using the diffuser. (thouh there is no reason to use the diffuser for macro)

The good news is that this is not a bad thing. Because even if you had plenty of light, you should not be shooting at F/22 on a D80. At any aperature smaller than about F/10, diffraction is going to cause your image to be blurry. You can probably push it to F/14 or so before it gets too horible, but by f/22 it is going to be quite noticable.

Read the following page about diffraction.

I disagree. I've shot plenty of macro with DS125 at ISO 100 at f/22. If I was really close, I would have to stop down to f/25 or f/29.

In the old days of film I would shoot f/22 with with two SS200's, shooting ISO50. Never had to even use full power.

Show us some shots. Either, something isn't working right or you are not shooting macro, i.e. you are more than .6 meters from your subject. IF you are 1 meter away shooting a 300-500 centimeter fish, then f/22 won't work. But then again, you wouldn't need f/22 anyway.

I also have tried to use a D80 at f22, ISO 100 and all my images come out black. I always thought that I would have to have two strobes to provide enough light for that small of an aperture.

With two DS-125 strobes, I can almost get F/22 at ISO 100 (it is still a bit underexposed). But canon lies about it's ISO. Canon ISO 100 is actually ISO 160. Nikon on the other hand is accurate with it's ISO ratings, so a nikon would need to use ISO 200 and two DS-125 strobes to get F/22.

Though don't forget what I said in my first post about diffraction. You would not want to shoot at F/22 on a D-80 anyway as diffraction is quite bad. By bad, I mean that it will cut your resolution in half.

Are you using the strobe with the right preflash configuration? You may be using the strobe in no-preflash mode so it dumps its full charge on the preflash not having enough power for the real flash....

Can you post an image? I have shot plenty of macro with d70 using lower powered Inon strobe and single ds125 with no problem at f22 and ISO 100.

I think a few more questions are needed, with those settings you state above:

1 How far away from the subject are you?

2 How have you placed the strobe, is it close to the lens or on an arm sum distance away?

When I shoot macro, (one inch or smaller) I have my strobes very close to the lens, very close and shoot within 6 inches or so and have shot as high as f/48

f/22 works for me!

Hello,

Think I found it , the problem, the flash mode was on TTL

now i put in on M and full flash. Think I lost most strobe power in the preflash.

More news afther the weekend

Ditto that. I just got back from a 3-day and I shot my 125's on macro all the way up to f45 with no problems. TTL might behave differently though. I shoot manually.

Hey,

Thanks for the answers .

The problem is solved, I had to put my D80 Int Flash on Manual, was on TTL.

I took some pics today , realy bad vis. iso 100 f22 1/125 and good pictures .
