It does not have an optical slave trigger, so no.
You could if you attached an optical slave to the flash foot.

The F58 cannot and I doubt that any will work wirelessly from another brand's IR flash signal. - TF
i tried play around with nikon sb900 and f58am, both off camera.
I set the sb900 to remote (the AF lamp blinking, waiting for flash-trigger), then i direct the F58AM towards the SB900, and press the "TEST" button on the F58AM. THe SB900 triggered, and flash.
But this dun work if i reversed it --- The flash from the SB900 do nothing to the F58AM.... This, normal ? or i set wrongly (the F58AM works well when flash-triggered by A700)

Again, the SB-900 has an optical slave built in. It can be triggered by any burst of flash light in addition to Nikon's CLS infrared protocol. The F58AM does NOT have a built in optical slave and requires either the Sony IR protocol or an additional optical trigger accessory to be attached to its foot.

All alpha flashes lack those types of optical slave triggers built in, but if you're using Sony's equivalent of Nikon CLS wireless flash, the optical trigger is unnecessary. Just set the camera to wireless flash, flip up the popup to use as the commander, and you're good to go.

An F58 can only be wirelessly triggered with an Alpha pop-up, F56, F58 or F20 flash. If you want to trigger it from a non-Sony body, you need a flash or radio trigger device and neither TTL nor HSS will work. - TF
ar... that is a little dissappointing....

The wireless flash used by the f58am is like a code and is patented. Only Minolta, Konica Minolta or Sony can transmit it. Data is exchanged between camera and the f58am, data such as flash power to use, flash duration etc. This is one of Minolta's key inventions.
Conversely the SB900 is triggered by, I think, a simple strobe that any camera flash can omit.

I asked One of my nikon frd (using sb900) bout this q:
Why issit that u use radio trigger to fire your sb900 off camera, instead of using the popup flash on ur d90 to trigger it?
His answer is:
because, if use popup flash, there will be a slight delay. Radio trigger is more precise.
whats u guys' say on his answer?

I probably will get this wrong but here goes.
In wireless mode the Alpha sends a coded signal to the remote flash to wake up and flash for a short burst the alpha then meters based on that flash and signals again the intensity and duration for the remote to use starting in x milliseconds and the remote adjusts per the instructions and fires. It matters not how many remotes there are, or how they are aimed. The control is based on the desired exposure wanted based on the TTL metering of the pre flash. If I remember correctly the flash on the camera is not used as a flash just a signalling device.

I've only used wireless flash with the alpha system, and can't say I would have noticed such a delay. It all happens very quickly. I don't know if it's significantly different with Nikon.
But another reason for using a cable or radio trigger to fire the external flash is that in some circumstances the signal flash from the popup/mounted controller flash may give a slightly visible contribution to your scene's exposure, and you might not want that. Another way to work around this is to place an ir-pass filter in front of your controller flash: the remote flash only needs the ir signal, not the visible light. Nikon even offers a ready product just for this purpose.

Hi
I just borrowed a SB900 from a friend, and I am trying to synd the nikon one but no success yet.
How do you set up the 58 to control the nikon one?
I guess the 58 has to be in wireles mode and te nikon in remote, but I can't manage to trigger the sb900 yet
