Fellas,
I appear to be misunderstood. Thanks a bunch, but I'm not looking for an advice on any workaround like LV focus or 3rd-party focusing screen. I only asked to contact other Pentax reps regarding that answer I was given and which I can hardly buy. Yes, I can come up from some NYC or Big Shoulders IP (I'm an IT geek working for an elfish company), but after I have already talked to Pentax USA they would be surprised to get about the same questions in the same writing (we all have unique writing... though... i can go this way... like i'm high... or smth... really... i know what time it is... Peace, bro!)
Nevertheless, for those of you who do not have this issue or who doubt on whether it's real or who are just curious and eager to see the samples, here are the images requested. Since I'm running out of space here on PF, they're hosted on my personal server (which is scheduled to go offline for most of May, sorry). Subject-to-sensor distance was about 2.2 meters (in order to be of x40-x50 of lens focal length), lens used was Helious MC 77K at f=1/1.8 (I usually do not go this wide, preferring smth around 2.8-5.6, but I'd like to put it into extremes to be more illustrative). K-5 files were dark-roomed thru DxO optics and ist DS files went thru Lightroom.
Focus indicator goes on from this focus ring position
to this position
The result:
It is way off focus, obviously.
Ok, let's twist things a little:
It's much better, isn't it? (hint: it's a rhetorical question, a figure of speech)
It was Saab logo in the center of the page (having enough contrast and provided with enough illumination) which I used to focus on.
K-5 AF system is adjusted this way:
For precise in-focus indication for old manual lenses I need to twist it backwards to - (minus) 140 um (having 'apply all' still = -10; it'll be around -160 for 'apply all' to be zeroed) in which case I'm loosing all AF-bility of AF lenses even if I set each of them to +10 in the legacy AF menu.
Thanks for looking, fellas, though I can't help but quote myself:
Quote: So I'm asking if anybody here could do me a favor and spend half an hour of his life on the live chat with Pentax USA on their website asking for details on the AF design and whether it is really not meant to work with M- and K- lenses missing those electronic chips.
I need some quotation of official Pentax Rep either which confirms our local Pentax Mordor or which I could use to force our nasty boys start doing what they ought to. I'm well aware of Nikon and Canon and Katzeye focusing screens and LV function and how PD AF systems work (in general, obviously they can use different algorithms e.g. implementing some disgusting easter eggs for old lenses to force customers move further and buy brand new ones). Just do me a favor and spend half an hour of your life for a phone call or web-chat with your Pentax rep, please.
Cheers,
Zig
