All those features mentioned below by Godrey DiGiorgi will not make ANY DA/APS lens/format perform as well as a really good FF pentax Lens ( even some of the SMCT screwmounts over 30 years old ) on a good FF camera in terms of sheer image quality. This is what I have been talking about in the thread. With DA/APS you have format limitations that cannot match what is possible with really good, even OLD FF lenses. Of course we all know there is no Pentax FF DSLR camera yet, but to say these OLD lenses are not as good as DA lenses is really not true. They are DIFFERENT, not better or worse, and if just consider them for what they are, LENSES, they can create a better quality IMAGE than DA lenses can once the proper FF body comes along to take full advantage of this capability.

If you want to buy a camera and take advantage of half of what you paid for by using old lenses on it, that's your choice. No question that you can do some nice work if you know what you're doing. But calling someone who wants to take advantage of pattern evaluative metering, linked AE and focus point, MTF prioritized exposure metering, automatic recognition of lens focal length for image stabilization, improved flare control, better image resolution, high speed/accuracy focusing with fine manual control, etc etc, lazy or incompetent is truly bullshit. All these things can add up to improved picture quality when exploited to advantage. For either an amateur or a professional photographer too. There's no doubt that high quality photographs do not *require* all these capabilities, but they can help. You seem to always want to choose doing things the hardest way, Corey. I don't see any evidence that your choice poses an advantage.
