How much of the R8/9 focussing is a function of the low mag factor, 0.75x, compared to the SL/SL2 with 0.86? My guess would be that it is measurable, maybe even significant. So one tradeoff would be to penalize eyeglass wearers with being able to see less of the frame edges in return for better focussing probabilities. The first time I looked through an R8, I was stunned at the apparent smallness of the image, even from the R4-7, which has 0.80x.

However, either way, a resurrection of the viewfinder engineering of the SL/SL2 would be welcome. Does anyone know if there is an engineering imperative that the quality of the viewfinder image deteriorate with electronic focussing aids? My uninformed guess would be that there is no such imperative and that N, C, and the others are simply going cheap, because FV/AF allows them to get away with it most of the time.

I am in favor of FV, but would not like to see obvious reductions in viewing quality.

It seems to me that Leica could kill the market (I don't mean making significant inroads on the numbers enjoyed by N and C) by
1. Resurrecting the engineering and overall focussing capabilities of the SL/SL2 viewing system.
2. Giving us FV, too.
3. Making their FV measurably more accurate then anyone else's FV or AV.
