This came with a camera I purchased from eBay as a kit. I really have no use for this as I already have a meter. I put in a battery and the incident meter(without the spot meter attachment works) and is accurate. The spot meter attachment has some dust inside and is not really accurate. I have no idea how many stops it is off by. My first test shows that it is off by 3 stops and the second time I tested it shows 5 stops. If you can clean it then it'll probably be back to working condition. Comes with Gossen case for the meter itself and the spot meter attachment. Also comes with instruction manual. In mint condition. I doubt it was even used...
Photos didnt attach for some reason the first time.. I was not aware that you have to adjust the meter when using the spot meter. Will try that when I get home later this evening.
That attachment was manufactured originally for the older, Lunasix 3 meters (IIRC). It is usable with the Luna-Pro F if you adjust the readings to take into account the affect of the attachment. That affect varies with the viewing angle set.
In my pdf copy of the manual for the meter, the information is on the pages devoted to accessories - page 28.
Still have not had time to test the meter yet. I'm seriously just trying to get rid of this thing. I have no use for it. Someone just make me an offer.
