And now for the remaining K-3 blur dragon to slay...
7 months ago

Has anybody given any thought to the DEFAULT AF mode setting?

"AFA" is PROBABLY NOT what you want your camera set to. Nor is it what your K-5/II/s was set to by default.

IF the computer randomly decides to go into AF-c mode for some reason, you can release the shutter while the camera isn't focused on anything.

Think about this and tell me that it isn't probably what's wrong with the other blurry shots that the high ISO NR isn't responsible for.

If someone has High ISO NR set to off or low and AF set to AF-S and they are still getting randomly unexplained blurry images in the future, I'd really like to hear about it.

These kinds of things are the "learning curve" everyone was talking about.

Thanks for all the good work You have done. My K3 delivers tack sharp images in RAW almost every time. Couldn't be bothered with jpgs, not even for giggles.

The above implies that the K-5 II and K-5 IIs also has AFA. They do not have AFA.

Just making sure there is no more confusion than necessary.

Thanks for the clarification. My K-x had AF-A. It was a disaster, always fighting me for control of quick-shift focus.

Good point Ron.

I was implying that because we didn't have that auto mode in the K-5/II/s, it couldn't be the default, but best to be clear for sure.

Ed,

When I'm hand holding the cam I generally use AF/C since I might lean in a little after the shot is in the focus I want.  In AF/C most cams will correct for an accidental move.  Hey, it doesn't happen that much.    Maybe I misinterpreted what you're saying?

Cheers.

It's amazing how differently we use our cameras isn't it?  That totally wouldn't work for me because I often use focus/recompose technique.  I know there are some situations where it's not appropriate and can lead to misfocus, but it suits me best for most of my shooting.

Maybe not for some but i thought that was a no brainer, I never use that mode, its either AF-S or AF-C the AF-A doesn't exist in my usage!

Most cameras designed for action and sports shooting usually have a menu option in AF-C that gives it 2 distinct modes. One is shutter priority which in this case means the shutter will trip regardless of whether it has focus lock or not.  Two is focus priority in which the shutter will not trip unless it has focus lock. AF-C mode normally runs such that between frames it takes a quick look and tries to adjust focus on the fly based on predictive AF if motion is detected. And why are these 2 modes in here you ask? You would think that option 2 would be the one you would want. But not for a pro making a living with the camera in sports. He would use option 1 most of the time. Getting a slightly blurry shot is preferable to missing the shot altogether. No shot at all means no money while a slightly off focus shot means PP. You can still sell that. Especially in print media where max sharpness may not be needed. The frame rate maxxes out in Option 1 while Option 2 slows down depending on the AF speed of the camera. Really serious pro cameras can be fudged into Option 2 more of the time but it requires experience. Most DSLRs I own have this option in them, even Pentax. For those not as demanding in AF-C then Option 2 is the best bet even if some split moments pass you by waiting for focus lock.

I used to hear people whine on here about not being able to get their camera to fire when trying to shoot sports (Opt 2). A simple matter of deciding what is more important. You just have to put it in Option 1 then keep half pressing the shutter while following the action to keep the focus continually updating till you want to fire away. That way the focus is always at least close. Shooting with as much DOF as you can get away with also helps but some prefer shallow to isolate a single player/car/etc. in focus. Don't use auto-ISO either just set it to the highest you can get away with. Putting all these features in auto modes slow the camera's CPU down with things it does not really need to be calculating.

dragon to slay... then check this ....
In reply to Qwntm, 7 months ago

There is a glitch in AF-FA (AF Fine Adjust) on the K-5 and K-5 II which was observed by me long ago and which was detailed by someone else later on (I'll try to find the threads).

On the K-3 you should check the following:

  1. Set the AF-FA value for a lens unequal to 0 (zero).
  2. shoot at least one image (Ia)
  3. turn the mode wheel such that the green-mode is passed
  4. shoot some images (Ib,Ic.Id,...)
  5. verify the AF-Adjust value in EXIF of the images

The AF-Adjust value may be 0 (zero) for image Ib and also for Ic,Id,...

That means, the AF-FA may be incorrect for all images Ib, Ic, Id,...

Just to mention this for the slaying

Kent,

With Pentax DSLR cameras:

In AF-C (with focus priority), the shutter will most certaintly trip even if you do not have focus lock. Every Pentax DSLR that I have owned works that way.

In AF-S (with focus priority) the shutter will not trip unless you have focus lock.

This sounds much more convincing than any theory I have read in the other thread. Good observation. I had left AF-A as soon as I switched on my K-3 for the first time - and I could not reproduce the blur issue. Maybe you have found the explanation finally.

I don't have a K-3, and the manual doesn't seem to be on Ricoh's web site.

Can someome please tell me what AFA is?

AFA is for "Auto Focus Automatic". In this setting the camera's computer "decides" whether  the camera "needs" AFC or AFS mode.

Never heard about AF.A before. Looked in the K-3 manual. It automatically chooses AF.C or AF.S, depending on subject. Eh? Does that work?

Set mine to AF.S and also NR Custom (off till 3200). I seem to be getting good results now.

Having said that, in "Green Mode" the AF.A is set and also NR to Auto. I would recon that many "noobs" getting this camera and using this mode will be unhappy with the pictures. Pentax should make sure that "Green Mode" outputs generic and good quality shots. I've not been able to get good shots with "Green Mode" and would think the camera to be rubbish.
