Hi Alex,
thanks for chiming in!
Thanks also for the review. It is always nice if someone gets how well Pentax DSLRs are designed with respect to ergonomics. I like how you took the time to get to know the camera and were able to appreciate its strong points.
I have one question and a few comments:
First, you conclude "
AF customization is lacking". Which customisation options are you missing? You will have noticed that there are a number of AF choices one can make including focus vs release priority (independently for AF-S vs AF-C), AF hold, etc. I'm genuinely wondering what else you are looking for. Is it just one more setting for "
ignore closer subjects that suddenly pop into the frame"? If so, does this justify the summary "
AF customization is lacking"? If there is more you would have liked to see, what is it?
Now my comments:
I think the vast majority of Pentaxians will readily agree that Pentax AF-C is lacking behind the competition. What I don't understand, however, how DPRreview or you essentially come to the conclusion that AF-C on a Pentax is pretty much useless. In your review you write that even lateral movement only provides a 2/11 (=18%) keeper rate. I don't understand that at all, unless you constantly have other objects interrupting the AF acquisition. The K-1's AF-C performance is not at the top of the game, but many examples from other users suggest it is better than 18% keeper rate for a non-challenging scenario.
It is one thing to say "If you are a sports shooter or want optimum AF-C performance for some other reason, stay away from the K-1" and a completely different one to essentially state "Don't even bother with AF-C.". I'll immediately add that to me AF-C performance is not important and I haven't subjected my K-1 to any respective tests. However, I've read other people's responses to findings like DPReview (who only seem to do the "weaving biker"-test when it is time to test a Pentax, rather than a 1D X Mk II) and yours and not all of those responses can be dismissed with the rebuttal "the DOF was huge in this scenario".
Perhaps you explored all options, but I think there might be the chance that some combination of AF configuration settings may have yielded better results for you. Some choices appear to be unintuitive, so for instance "release priority" appears to result in more keepers than "focus-priority" for some users.
BTW, your 8.3% keeper rate for the horse jumping competition sounds absolutely awful, but isn't it true that you could have gotten a lot more in focus shots by applying some simple technique? For instance, a shot with a horse clearing the fence should be dead easy to get by focusing on the fence and then just pressing the shutter release button without even focusing before. That seems like something entirely reasonable to do, AFAIC, as opposed to being a workaround for a non-working AF system. I believe -- I could be wrong though -- that in the right hands, the K-1 could easily be a great wedding camera. More help from the AF system is always welcome, but I just have trouble believing that the K-1, as is, is not fit for weddings.
Regarding the lack of a"
dedicated AF point selector": With a simple menu setting, the four-way controller becomes a dedicated AF area selector (it then takes an extra step to use the original functions of the four-way controller). N.B., the four-way controller really is an eight-way controller because the buttons are shaped in a manner that allows one to press two simultaneously in order to achieve diagonal movement. I personally actually prefer buttons for controlling the selection of AF areas over a joystick. I'll admit that I'm not a sports shooter and I could see that for 51 AF areas one may want to use such an input device for very quick adjustments but for the amount of AF areas the K-1 offers, I prefer the discrete action of buttons. In a pinch, I can shift the selected AF-area without even having to check the visual feedback, because I can simply count the clicks or my muscle memory does it automatically.
Finally, you may be more hesitant to dismiss the green button as being dispensable, if you explored its functionality some more. In manual mode, for instance, it can be configured to adjust the aperture or shutter speed. This makes it really easy to make certain choices, get an initial standard exposure by pressing the button, and then continue manually. It supports a "semi-automatic" approach that combines the convenience of automatic modes with the predictability and consistency of manual shooting. A similar example how useful such semi-automatic modes are is the option to perform an "AE-lock" in manual mode. It allows one to fix an exposure setting by having the camera automatically adjust either shutter speed or aperture, depending on which other parameter the user changes. This is great for flash photography, as it will keep the ambient exposure constant while allowing to season the flash contribution to taste (as the flash is only influenced by the aperture setting for shutter speeds that do not exceed the sync-speed).
