Diameter of body and number of blade are two similarities.
I also don't like the idea but there are a lot of similarities.
15 elements in 11 groups vs 15 elements in 12 groups is not a big difference, could be because of ed glass.
Proportions and weight are very similar, lens hood and filter thread is identical, same minimum focus distance.
Minimum apperture at wide end is different but could be because of ed element.

Originally posted by D1N0 I don't think Pentax could get away with interesting flares like this:
New elements "2 aspherical elements, 1 ED element and 1 made of glass with anomalous dispersion" could fix that problem and a few other things. New lens is obviously different because of those new elements and some other body changes but I still think that new lens could be based on SMC Pentax-FA 28-105mm F4.5-5.6 IF.
