Hi all,
being a constant reader, but a rare poster on this marvellous forum I really need to address you for help.
4 days ago my new K-1 together the DFA 28-105 (€2,000, not a bad deal here in Germany) arrived and boy was I excited. After K-20D, K-5 and K-3ii now the gold standard! Off I went taking pictures, but what the #*?/. Not a single one in focus, all blurry! Well, probably shake related, I can't yet master the 36 MP @ 1/125 give or take. Do some proper tests, you fool! This I did, hopefully.
Put camera on a sturdy enough tripod, remote release (3s) on, SR off, pointed at neighbour's roof 50 meters away, which was lit by the winter sun. No wind at all. Iso 100, 1/125 @ 5.6, which is wide open @ 105mm. Didn't work: very strong blur everywhere, definitely no BF or BF. Same with different settings. Next try: LV and ES, et voilà, picture reasonably sharp all over. An obvious solution comes to mind (please do correct me, if I'm wrong): the notorious shutter shake. I have studied almost every thread on PF regarding this topic.
Btw, similar results could be seen with my other FF lenses the (HEAVY) Tamron 70-200 and the Tamron 90mm Macro (no LV support for them).
Especially the latter showed some interesting results: wide open, i.e. f2.8 @ 1/320 the image was razorsharp, then stopping down (and entering that dangerous range from 1/200 and below the outcome deteriorated significantly showing even some slight ghosts of nearby twigs. It got better again with f7.1 @ 1/30. So, this has to be shutter shake, hasn't it? If yes, there's no doubt about sending that combo back. Those workarounds discussed here and elsewhere are not for me. I want to take photos (just like with my wonderful K-3ii, which I'll keep anyway as a backup) without being always on the alert for potentially ruined images.
My questions are: how good are my chances to get a decent copy of the K-1? Are all K-1s affected by that problem, but to a varied degree? Can anyone confirm that his/her copy WITH the 28-105 does an excellent job even between 1/80 and 1/200?
One more thing: with my Tamron 70-200 I observed a (maybe) strange behaviour. After focussing and then releasing the AF-button the focus didn't seem to be fixed (a zzztish sound could be heard from inside the camera as if the focus was changed by itself) and after pressing AF again there was a slight readjustment. Is that normal or am I missing something? Camera was on tripod with no movement and no SR.
I know, the decision is for me to make, but some advice would be appreciated. Because, you know, I want her so badly!
Kind regards
