Not that I'm against Pentax (actually it's just the opposite and I consider myself to be one of the strongest Pentax supporters), but I also don't follow the Pentax path blindly and I'm aware of its (numerous) weaknesses. The 1/2EV IS actually quite a difference. The speed of f/4-5,6 has always been considered to be the sign of the amateur segment. The speed of f/2,8 has always been the sign of the pro segment (I'm reffering to the standard zoom lenses now, of course) and the difference between both segments is ONLY 1EV. So the lenses 1/2EV slower from the pro ones are considered by many users to be "semipro" or something. It is the big difference in terms of psychology, marketing etc. Prices of those "middle-way" lenses also reflect their superiority to the f/4-5,6 lenses - they are considerably more expensive. Not to mention, that they are often equipped with IF, AL and bayonet-mount hoods - three things the SMC FA 28-105/4-5,6 lacked. Yes, the SMC FA 28-105/4-5,6 IF has IF and a hood, but remember that this is actually the Tamron lens and, according to the KMP, it was introduced in 1999, i.e. the same year the former lens was discontinued - which means it's a sort of its successor. > >Just remove the top & front cover and see for yourself.

Is the camera's SKELETON made of plastic or of metal? If it's made of plastic then the metal mount doesn't make any serious advantage, because the whole SKELETON is unable to carry a really heavy lens... Regards Artur
