They have designed entry level with limitations for years. Theres no change. > 2.

It wasn't necessary on the Z-1p either but that didn't make aperture rings on all lenses dissapear. > > To 1: > From *ist and *istD we see, that we have in the future no more compatibility > to older lenses, even if this is technically feasible, since it is not not > wished from Pentax. Theres no logic in this.

This isn't true. Pentax have chosen a simple (like competition) electronic metering system. Keeping compatibilty would have meen keeping the expensive system used on the MZ-S or even more expensive: keeping a double metering system for different lenses. > Therefore also all new lenses will be only FAJ lenses (see already 18-35), > because an aperture ring disturbs only the *ist cameras operation. > It is intended, that these lenses should no longer work to the MX, LX or > Mz-s (see 1), because it is supposed that new cameras should to be bought. > > Pentax loses thereby the only selling arguement in relation to the > competition, the k-mount compatibility. It never was a selling point. 99% of buyers of new cameras, whether they are Pentax, Minolta, Canon or Nikon, couldn't care less about compatibility of more than 20 year old lenses. > Why should I buy a *istD with the > pertinent lenses, if I can not use these lenses with my LX and MZ-S? The vast majority who buy a DSLR, yes even the Canon D10, don't sit on a phletora of 20+ year old lenses. They don't sit on many lenses at all. The majority are people who want the latest digital toy. Most of them don't come from slr owner ship at all. They don't know what aperture is and will be confused by an aperture ring. Pål
