I just recently purchased the above meter, used. It seems to be accurate in tha t it matches pretty closely the readings from my girlfriends new Sekonic spotmet er. However, if I try to take a reading that is less than about 5 or 6 EV's it will read zero. I have to activate the meter from a more brightly lit place, ke ep the trigger pulled and move back to the darker area for a reading . The read ings taken in this way are accurate. Is this behavior normal for a Pentax digit al meter or is something in need of attention ?
