Oct 20, 2005 18:37:13 while it would be tempting to go for the highest Dk; it is more usual to go for the lower Dk. THat's because the lens is more durable and does not crack or chip so easily with a lower Dk. steve |

RE: RGP with the highest Dk?
Oct 21, 2005 14:39:18 As far as I can remember, the ML lenses quote two DK's as they are given in two units. The Fatt and the hPa units. For example, (please check the figures) but the ML92 has a DK of 25 & 52. The first is in hPa and the second in Fatt. So therefore it doesn;t matter which one is quoted as long as he units are quoted as well. Please double check the values as I have done it from memory and probably embarisingly got it wrong haha. |
