This has me thinking !

If an r87 filter has a compensation of, say, 8 or 16 steps, how come you can convert your camera, in which they place an r87 filter on the sensor, and then go about happy-shooting?
My "reasoning" is that an r87 has a certain density, no matter if it is in front of the lens or behind it.


So how can you shoot at higher speeds with a camera conversion, but not with a filter?
