If your cam only has auto-iris, you'll get what's called an iris flare - the picture will be too bright or too dark momentarilly as the iris tries to compensate.

 In the past I've used my GR-DVF10 (auto iris) to shoot action (surf, dirtbike jumping, etc.) and haven't had any problems with the 'iris flare'.  However, it would be a nice feature to have.  How much does this feature increase the product's price?
