Just plonk the cameras on a tripod and choose a scene with plenty of detail in the corners of the frame. A shot in a park with lots of trees is probably the best.<BR/><BR/>Use a pre-DA lens, preferably a wide angle such as a 24mm. I'm sure wide angles is where most of the difference will be due to their wide image cone.<BR/><BR/>If you didn't live on the other side of the country I would let you borrow my FA 20mm :-)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4063079619074407721.post-86818348347590014312008-11-15T20:22:00.000-08:002008-11-15T20:22:00.000-08:00Thanks for the information.

I don't understand why Pentax doesn't advertise such improvements in the technology while other brands do?Kamarajuhttps://www.blogger.com/profile/04369145134689681174noreply@blogger.comtag:blogger.com,1999:blog-4063079619074407721.post-65357243386522342322008-11-15T13:17:00.000-08:002008-11-15T13:17:00.000-08:00When the K20D came out there were a lot of posts a...When the K20D came out there were a lot of posts about how suddenly existing lenses looked better... in ways that the pixel count alone could not account for. Part of this was focus accuracy and perhaps more was due to the rendering the new pixel arrangement made possible. Anecdotal evidence, sure, but if it was a random subjective effect I'd expect some posters to remark on the opposite. No-one did.robinhttps://www.blogger.com/profile/08743788064455642852noreply@blogger.comtag:blogger.com,1999:blog-4063079619074407721.post-73961419806853639072008-11-15T10:41:00.000-08:002008-11-15T10:41:00.000-08:00Misere,Good article.

However, I don't have a setup such as Phil Askey for instance. What do you suggest for test? Bright colors with fine details? Same photo at same location, unretouched at all in RAW then converted directly to JPG or just JPG? Will the naked eye be able to see the difference?<BR/>I will be glad to conduct these non-technical tests along withthe other DA/DA* lenses test for use with full frame.Of course Pentax is not getting on the bandwagon for full frame, but one can revert back to your Love letter to Pentax. They may still do it.Anonymoushttps://www.blogger.com/profile/16363645754592641317noreply@blogger.com
