Recently I'd order a mini 24cmx24cm soft box for my 622mkii for the intention of shooting portraits using off camera way (Situations where no light can be bounced off). I'm not sure if its a recommended way but just experimenting it since the soft box costs less than $20.
So far I'd not seen many photographers shooting using off camera flash method, other than professional strobists. Will the mini soft box help in any ways and are there any pros and cons using this method? Other than the inconvenience of holding the flash in one hand or bringing a light stand with you.
