I have some photos taken using the A 28-135/4 in the Pentax Lens Gallery at http://plg.komkon.org/a28-135_4/a28-135_4.html . The pincushion at the wider end of the zoom range does show readily in the brick wall photos, and would certainly be a problem for some architectural photography, but, hey, it's not really designed for architectural photography (or for "brick wall photography", either - <g>). (Myself, I'd be using only primes for situations that required low rectilinear distortion.) Fred
