This happened to me last week. I love the K-7 and look forward to improvements so I am not unhappy. But never the less this did happen.
I shoot birds with a K-7 and sigme 300mm f2.8 ex dg apo.
That out of the way. I was in a forest under the canopy with 4 other canon users. All with 100-400 and 400mm 5.6 lens. So i was confident i could hold my on with them with auto focus. Wrong!!!
While they were using 5 year and older cameras. I was sporting a K-7. They were banging away just blazing. I many times had to put my camera in manual focus to get close then AF would hit. After doing about 10 times they all looked at me kiinda funny. But didn't say anything.
This was at 5:30 in the evening and in the jungle verrrry dark. But this is a real situation where i found the really bad AF of Pentax. Now i got some birlliant shots.
Fast glass is the factor. And,,,, I had to take off the 1.4 T.C. at F4 to even get focus.
I hope Pentax works on this.
I have invested in Pentax and love the color and pix. But I would say they are 3-5 years behind in this area.
My opion only.
