My take on this is the following: There's no wonder that cameras do indeed change the exact values of exposure parameters. This is nothing new. Oe will display 1/30 at f/2.8 (AV mode) when really the camera decided to use 1/27 but for clarity purposes, displays 1/30. I have no problem with that.

Hehe, got your point Larry but there's a difference between promoting the good things of a product (not stating bad ones) and bold lies. I'll add that politics lies are no reason to accept lies everywhere else except maybe if this is the world one wants to live in. 2010/11/4 Larry Colen

Maybe Pentax just uses slower lenses (they do) and doesn't correct (no idea since the data wasn't there). The funny thing would be if they didn't correct there would no evidence of it in this data but rather in inconsistent exposure results between lenses. On Wed, Nov 3, 2010 at 10:43 AM,

I believe the article is written using an overly hysterical tone. This isn't news. It has long been known that the metering in many digital cameras takes the maximum aperture of the lens into account. In the case of Pentax it was discussed when the K-10 was a fairly new body (I believe Ned
