Correction: It is shutter speed. :nono:Definitely possible - aperture size should have no bearing when using any flash unit.
guys think thats possible...?
lo
Why do you want to do so?? Your shutter speed will be very high...

Why do you want to shoot f1.8 using studio flash in the first place? :dunno:

If you don't know what you're talking about, please don't correct and say it should be shutter speed. So long as the shutter speed used is within flash sync speed of the camera (or lens if it is a leaf shutter), one can use any aperture. Obviously since TS mentioned studio flash, the issue he will probably face when using such a large aperture is how to throttle back the flash output. So long as one can get the desired exposure, there is no reason why a large aperture such as f1.8 can't be used, perhaps to get a very narrow DOF.

So long as the shutter speed used is within the flash sync speed, for a given exposure value (EV), any combination of shutter speed/aperture can be used. If for example, a meter reading for a still life using a particular studio flash setup is say 1/15 sec at f5.6 (EV9). If the exposure is kept the same, one could also shoot at 1/30 at f4, 1/60 at f2.8 or 1/125 at f2. Obviously while the exposure remains the same, DOF, sharpness, etc. will differ. Could it be shot at 1/250 at f1.4? Only if the camera's sync speed is slower than 1/250 sec.
Here I'm not even talking about flash power as the assumption is that the flash output is constant. Obviously in practical terms, using such a wide aperture may be impractical or counter-productive as one would need to use ND filters, increase the flash working distance, etc. to throttle down the flash output to prevent overexposure. These are remedies to reduce light output but it doesn't prevent the use of wide apertures.
Nothing wrong with using big apertures wat, whoever said studio must be everything sharp?
