So you're shooting in manual, right? You're setting the shutter speed you want to achieve an artistic effect, but you can't control aperture. HOWEVER, you CAN control ISO, the sensitivity of the sensor, from 100 to 3200! I think that's your ticket.

You could also obtain an ND filter to increase your possibilities, but it would be a pretty large (expensive) filter. Or if the price doesn't bother you, get TWO polarizer filters and stack them. Turning one and not the other will give you the same effect as an iris, with much more range but no improvement in depth of field, and a possible loss of sharpness. It might also mess up color, but that's PhotoShop-able. I really should do that for mine!

the minolta Af reflex 500mm f8 comes equiped with a dedicated 'drop in' 2x ND filter



this lens is so well designed you must remove the clear qlass filter (so that the ND does not add an optical element) !!!



the filter stores in an internal compartment in the soft slip-on lens cap
