Raynox has these two snap on close up filters. The 250 is an 8x and the 202 is 25x, if I recall rightly. My question would be whether the 202 has significantly lower resolution than the 250, and whether the 202 has an uncomfortably close working distance. The way I see it, the two filters are very similarly priced, but I expect the 202 to have less resolution and harder to work with. Does anyone have experience with one or the other?
