Negatives:
- The front is (unlike in the picture) is not silver-reflective, but only silvery matt gray, reflecting thus not very good
- The metal frame is a little too big - thus the unfolded reflector is not really plan, but slightly curved so that you can direct the light does not control / uniform
- The back is light gray - and would definitely useful in white (as a soft reflector) - the light gray is neither good nor as gray card as a brightener.
The review refers to the Pentax-reflector from the supplier 1A-PHOTO-PORST (Stand 07/2014) - this only as an indication, since I can not exclude that the products from other suppliers in the relevant details different (hopefully better) are executed ,
