Well... I shoot in Av-mode with auto ISO set to 100-8000 and depending on the light I may also set the ISO-change-speed to Fast.
I have set it to back button focus with AF-C and Sel M, center point. In the C-menu I have C16 set to 3, the rest of the focus settings are default.
I use the D FA 150-450 and the focus speed on that lens is one of the fastest I have used on a Pentax. The hit rate compared to DA*300 is really high. In some degree due to the focus limiter I guess.
I've never used Av mode with auto ISO (it's a method I haven't explored). Isn't the lack of control over shutter speed in Av an issue, or do you control that by adjusting your aperture? I don't have much experience with bird / wildlife photography, but my assumption is that I'd want control over my shutter speed and aperture - hence TAv mode would be most suited. I'm interested to hear you're using Av for this...

What happens when you shoot against a bright sky and the camera compensates by giving you too low of an ISO and an underexposed photo? Or when you shoot into the shadows and the camera gives you high ISO and an overexposed photo? I've found the best way to get the best exposure is Manual Mode. Learn your lenses, how they react to different lighting situations, and don't always trust the exposure meter. But, everyone has their own preference. It's the end result that counts.

I knew they weren't going to be as high as my primary camera, but my secondary K3 (I carry two cameras at a time) has 3,568 and my girlfriends K3 has 6,742.

When moving from one light to another TAv may hit the limits and result in over or under exposed images when you see something and rapidly take a few images.
Using Av and A-ISO you will not hit any limits unless extremely extreme. The settings Slow, Normal and Fast in the Auto ISO-menu will give you the slowest shutter speed exceptable for the lens used, i.e to not get handheld blurr. With the 150-450 I get 1/250, 1/500 and 1/1000 as slowest speeds @ 450. So shooting birds I set it to Fast. That is for when moving arround, ready for the unexpected. If stationary I use Manual mode.

I find that Av+A-ISO @Normal setting gives me the control I need in most situations.

If I have enough light the ISO will hit bottom @100 and the shutter speed will go faster.

When I'm using TAv, I usually depend on matrix metering - however, if there are strong contrasts in lighting, then I either go with centre-weighted or spot metering and lock the exposure against a medium-lit part of the frame. It works for me, well enough that if I do have a little under or over exposure, it's well within the boundaries of recovery. I use Manual mode regularly also, but that tends to be for my more considered shots.

Very interesting - thanks for the info, I'll have to give this a try!

You guys need to step it up


I'm also shooting a K-01 and a K-5 during this time, but looking at the shutter count on the K-3, I'm half way to a new camera. The funny thing is, the K-5 Ihad before the K-3 only has 14,500 on it's shutter. I guess between Tess stealing my first one, another 6 months with the K20D buying the second K-5 and then the K-3, there just wasn't a lot of time.

I could match that if I quit sleeping and just stayed up all the time.

You all should get an Electric Drill put it in reverse and set the count to 5 and list it on Ebay as Minty. We used to do that with our 56 Chevys in 62 . Thats the 20th Century for those of "middle age" when every thing was Black & White( We Put the Drill on the Odometer)
