OK, But I want you to look at a list of the pros and cons of K/M AE vs (GBHMSAE). <Green button hypermanul semi automatic mode> when I finish it. Its work in progress at this point.

O'Connell Subject: Re: Camera engineering (was Re: Rename request) I think we are agreeing here. But I am saying that I rarely use Aperture Priority, no matter what kind of lens I use. That is why the current kludge is adequate for my needs. I am not saying it wouldn't be better to have the option, just that I would almost never use that option. I realize others may be different, but this could be one big reason why many good photographers are not as frustrated by Pentax's choice here. It is sort of like saying that Pentax doesn't have the best AF system in the world, but since I don't really push the AF and don't use it much, that is not a big problem for me. For someone like Herb, this is a big issue. So some on the list may not see mediocre AF as an issue just like I see mediocre support for K/M as not a big issue for me. So to summarize - Pentax does not offer what it could/should with K/M support. That is, they only offer HyperManual when they could have offered both HyperManual and Aperture Priority. For those who want/use aperture priority, this is a big deal. For those, like myself, who do not use Aperture Priority, but do use HyperManual heavily, the support provided is generally adequate and not something to get worked up about. Can Pentax do better? Yes, they could bring back full support of K/M lenses. Hopefully they will on a higher priced body at least giving the option of using it. If they don't, then there are a certain number of photographers that will be left out in the cold and frustrated. I will not be one of them, however. Ironically, the place Pentax is hurting much more is not in K/M support, but in AF performance (tracking, low light) and image stabilization. These two areas cause a far greater loss of sales than the K/M issue. It remains to be seen if/how they will address this problem. And yes, the cost to address the K/M issue is almost nothing compared to the AF/IS problem. -- Best regards, Bruce Friday, September 23, 2005, 10:14:17 AM, you wrote: JCOC> No Bruce, don't get me wrong.
