Originally posted by Rondec I would just say that it isn't a big deal either way. Cameras which have AA filters take more sharpening than cameras that don't, but in the end, you have a really hard time telling the difference between them -- except if you have moire. On the other hand, there is no doubt that removing the AA filter improves lens performance on DXO Mark's testing. So I guess there is that.
Back in early 2013 I finally found a good used K5 classic at a great price. At that time, the K5II and K5IIS were still relatively new and pricey, and I wondered if I should just wait a lot longer for the K5IIS price to come down, but I was ready to step up at that time. I checked the no AA K5IIS photo examples that were being posted at the time and concluded that there seemed to be very little visual difference that I could tell, and most of that difference could be treated with good sharpening techniques. So I thought at the time that if that is all there is - just go ahead and buy the good value used K5. It was really only the AA vs no-AA difference that I was concerned with. I'm very happy with the K5 classic.
Since that time, however, I've heard of nothing but raves from K5IIS owners about how much better and clearly noticeable the difference is compared to the filtered K5. And, DXO stating that it is some 20% better. If it was that much better, shouldn't I have been able to easily discern the difference in early 2013? Seems like I should have been. And yet, I did not. And, in addition, you would have thought that if the improvements were that readily visible, we would not have "endured" a decade or more of the horrible AA-filtered cameras that the engineers were gearing up for us. Were they duping us this whole time? And, their companies? I don't know, man, maybe they were the same engineers that were designing diesel engines for VW. I think there probably is a difference from removing the AA filter - it is just not that much.
Originally posted by Rupert I would have never guessed that there would be so much controversy over a filter vs no filter! I guess it's sorta like squirrels....you like them or you don"t.
Yes, I like them. You know, however, that they are just rodents with furry tails, don't you? Pretty cute, however. One fell out of a tree near me recently. That does not happen very often. After a short while he got up, shook it off, and went back to his business.
