Re: Pentax AF 18.5/2.8 for SLR
That would be my guess. The $600 digital point-and-shoots now have 8x or 10x optical zoom; it's going to be hard to sell DSLRs into that marketplace if all they have to offer is 3x optical. (I think Sony now combine 7x optical with 8x digital for 56x zoom!) > More like a consumer DA zoom. > > Yours regards, > Alan Chan > http://www.pbase.com/wlachan > > >A 10:1 zoom ratio.

Re: Pentax AF 18.5/2.8 for SLR
There's confusion between two patent applications here. One is for an 18.5mm wide-angle. One is for a zoom with about a 10x zoom ratio. Len confused everybody by replying to a post that mentioned the wide angle lens in the subject line, but talking about the zoom lens, not the wide-angle. > I don't have the URL anymore.

Re: Pentax AF 18.5/2.8 for SLR
I'll have to wait until I get home to check this. Hotmail isn't as friendly to use on outrageously long URLs as Outlook is. But, if you are absolutely sure that there is no mention of a zoom, and we don't have a reading from any of our Japanese speaking membership, maybe I'll just take your word for it.

88 degree angle of view and f/3.5, was Re: Pentax AF 18.5/2.8 for SLR
By the way, here´s one with a half angle-of-view of about 44.degree, and F-number of about 3.5": http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=/ netahtml/search-adv.htm&r=1&p=1&f=G&l=50&d=ptxt&S1=6490101.WKU.&OS=pn/ 6490101&RS=PN/6490101 That should about 88 degrees viewing angle. They have hidden the focal length, you have too calculate it from the formulas, so it´s hard to say it is for FF or APS size sensors.

OK now I'm confused. If the diagonal angle of view across an APS frame (almost the same as the *ist D sensor) is 88° then this lenses actual FL would be approximately 18mm.
