Hey all, I'm a new owner of a shiny Pentax K-7, and so far I love it. Glad to have landed here in the Pentax camp... looking forward to exploring the world of Pentax glass!
I have a small foible with my K-7: the half-press of the shutter release has
very little resistance... just barely resting my finger on the shutter release is sometimes sufficient to trigger auto focus behaviour. I shot for an hour in the rain last night, and this characteristic seemed to be somewhat exacerbated (water creating enough friction to inhibit the button return, perhaps). Once or twice in about 500 shots it's led to me involuntarily 'fluttering' the half-press, and re-autofocusing when I didn't intend to.
I've compared the resistance to a display model at the camera store across from my office, and it has slightly more resistance (albeit still quite sensitive); noticeable, but not enough to convince me that the half-press on my shutter release is defective, or has an abnormally weak spring. Could be down to sample variation.
I've also compared it to a few nikon dslrs which have a much more positive half-press button-detent than the k7, but that's comparing apples to oranges, I suppose. Probably not relevant.
I should also clarify that the full-press resistance is fine, and has a very positive click - no problems there. It's only the pre-release push (which triggers the af behaviour) which feels curiously delicate.
Can anyone else comment on their experience with this, and affirm/disaffirm that something's odd here?
Thanks in advance!!
