Ever had a lens/body combination which just won't work?

DA50 1.8 and FA50 1.4 will not work on my K-50; AF adjustment would need to be about -11 for it to focus correctly wide open. at -10 it is just ever so slightly off, and wide open the DoF is small enough at portrait distances to show it. Funny thing is I tried the FA on a K1 and it also required and adjustment... of -2, and I tried the DA on a K3-II and it required a -1. Neither of the other two cameras I tested need any other lens I have to be above +10, which means for whatever reason my K-50 hates 50mm at wide apertures. Anything at f/5.6 or narrower images are tack sharp.

Winner: Pentax K30/50 in heavy conditions compared to Canon etc.

I'd be interested to know what Canon models they were comparing it to. anything worse than upper midrange (70d,80d,90d, etc) models would have no sealing of any kind (including 77d) and are cheaper composite plastic. Basically if the models have different model names depending on the geography, you can be sure it has no protection from the elements. My guess is if they're comparing directly against the K30/50/70/s2 they are using the T6s/T7i/T8i/77D/M50/m62, all of which would fall into the toy camera category if out in adverse conditions (weather, dust, etc)

Better to buy Pentax 77mm or 85mm* ???

I would say from wide open to about f/4 the DFA*85 holds a definitive edge. From f/5.6 onwards both lenses start to get closer in quality; the modern lens is always a head but the 77 has improved quite a bit.

However from a fatigue standpoint I get tired quicker with the massive DFA*85 than with the 77mm, having rented both. The K1 body is already decently heavy. If you're only in a field for a couple hours or will be using a tripod or monopod I guess it doesn't matter as much. On 3-4 hour days hand holding it can be a bit tiring.

Muted profile or natural profile for better post editing

I think muted is better for grading if you want to learn that, the other profiles have too much saturation. but without a log profile and only 8bit you obviously can't grade as wide as something like the Panny S1H.

pixel shift mode - multiply resolution

you may be thinking of other brands. Olympus and Sony both upsample the pixel count which can still lead to demosaicing artifacts though at that high MP a downsize with a good resampling filter should fix it. Pentax upsamples the subpixel array which gives you the full RGGB array for each pixel, theoretically eliminating any demosaicing artifacts.

K3 II crazy shutter

Anyone experience an issue where the shutter (or mirror, can't tell which, I just hear the slapping) continues to actuate for several shots even though it's in one shot mode? I noticed it the other day using a 50-135mm with a dying SDM drive. I took a shot then I hear a whole bunch more actuations like it's been possessed by the gremlins of the SDM.

I had 2 EOS 1vhs at one point. Did I like them so much I bought 2? No. I accidentally clicked the submit button twice back in the dark ages of the web that was 2006. And the business closed their doors shortly thereafter. so I got stuck with an overpriced film camera for a few months trying to pawn it off on ebay without losing too much money. thankfully I just about made even in the end.

I'm hopeful that the Nikon Z6/7 and EOS R5 can restore some level of respect to mirrorless toughness. Honestly I've used most of those cameras on the list; the only one I would trust to travel from Greenland to the Sahara to the Antarctic is the K1 and K1-II. It's hard to describe, the others feel rugged, but the K1-II feels like I can stick to mother nature and smash that shutter button like nothing is happening. Honestly wish there are more AW lenses though, only the 70-200 2.8, 50mm 1.4, and 85mm 1.4 are designated AW D FA lenses I think.

I'm glad I'm not the only one who experienced this. I bought 4 (!!) copies of this lens at one point; 3 were sharp from f4 and another one from f4.5, but that one could have been decentered. I gave up trying to find the mystical sharp copy at f2.8 that the reviews implied. It wasn't just soft; it had real problems wide open in high contrast indoor situations that I've never before seen in a lens before. If there was a "high-end" lens that I could hate more, I have yet to find one.

did anyone else notice it only has 1 UHS-2 slot? after using this setup on the A7iii and comparing it to the Canon R6, kind of feel skimping on having 1 UHS2 slot means it just has 2 UHS1 slots. That said as long as the slots can actually hit 90MB/s in UHS1 mode I that's a far better result than what Pentax cameras can do now (unless the KP is faster, which I've never tested)

well I just got screwed out of $200 by Adorama by trying to partake in this deal. I ordered the 85mm, got the $200 certificate, spent it, then Adorama cancelled my lens and claims now that I owe them 200. note, they refunded the lens because UPS "lost" it, and instead of sending me another one decided to refund me the lens. I tried to place an order for the lens (without the 200, it was over by then) after confirming with the CS supervisor to make everything whole and now my account is suspended until I pay them back the 200. DO NOT BUY FROM ADORAMA.

MS cash infusion to Apple is a statement of fact, and should not be in dispute. Aug. 6, 1997: Apple Rescued ? by Microsoft | WIRED. PowerPC had significant advantages over x86 up until the Athlon64 where it started lagging behind, but the problem was System 7 (and 8 and 9 after it) was not a pre-emptive multitasking OS that NT (and to a lesser extent, Win9x) was; Apple wouldn't have a fully protected mode preemptive OS until OS X was released in 2001. For people who used computers casually, Macs offered little benefit over cheaper PC clones of the time.


IBM's noncompetitive hardware aside (which wasn't absolutely true, they just weren't competitive at the same price point, but instead you got full 100% PC BIOS compatibility except for the PCjr), OS/2 was their operating system to replace DOS. It failed, for multiple reasons, but primarily due to lack of consumer and developer support, hurt by their ineptitude on how they treated small developers.

it's this exact type of thinking that sunk IBM in the 80s and 90s. glad to see that same type of marketing naivete is pervasive still into the 2020s. IBM and MS both used to sell compilers for their respective operating systems, and made a bunch doing it. They couldn't have loved the fact that Borland sold their damn compilers for $49, when the IBM version cost upwards of a few k. Fast forward to 1987 and the newly released OS2 didn't come with a free SDK or open documentation like DOS did, to do anything useful at the system level you had to fork out over 2k for the IBM tools. I'm sure IBM would love to sell to every programmer 2k worth of stuff, but most hobbyist and small developers told them to piss off, and continued DOS and Windows shareware development. Fast forward to the 2000s and MS through Windows Mobile and Windows Phone 7.x limited development to MS only tools, and again, an already niche system never saw any sort of grassroots support because people want to use what they are familiar with and can make money off of.

No 1st party developer wants you to buy 3rd party addons, but they all accepted it because it helps draw and keep people in your system. Case in point, the new RF and Z communications could have easily been locked to 1st party lenses, the technology is already there, but neither of them did so. Why? because they accept that 3rd party is a fact of life, and it helps them more than it hurts them.


Nobody is saying it's a bad strategy to make money by selling at higher prices. But history has shown unless you have name cachet like Leica or Hasselblad, or LV or Prada, high margin low volume does not work. Remember even Apple in the 90s? More costly than PCs for almost comparable hardware, arguably better usability. Almost dead if not for some fortuitous events and a cash injection from MS.
