I will not be the first or the last amateur or professional to tout the merits of this immaculate product. But beyond that, so many reviews have been written about this archival quality photo glass that my comments would be a song of praise. So suffice it to say that this is all the best that has ever been said about him. Combined with one of Pentax's excellent DSLRs, with or without jitter reduction, you can expect some of the finest, sharpest and most detailed images you can capture. So that!
