I work for the DoD, so while we might not do any real systems engineering, we're going to have 12 formal design reviews. Each three full days, with 14 managers and 5 engineers present. Some of them will be paying attention. 25-page checklist including detailed entry and exit criteria for each. And to close out each review we need wet signatures from 22 different competency leads, each of which can just sit on the document for three weeks, or refuse to sign.

I'm a working engineer. Okay, a working manager who supervises engineers.

I have a 3D printer. It's broken, but parts are on order. It only prints things up to 120mm on a side, so we'll have to make compact cameras. I also have a passing knowledge of BASIC Stamp microcontrollers, also Linux.

All this and a few rolls of duct tape and we're only 4-5 years from finishing an *istD equivalent in my garage. Let's go!

We're not actually going to do good systems engineering, are we? You know, like define all your requirements before you start building stuff? Can't we all just get in a room with a six pack, a CAD program, and see what we come up with a few hours?

I'm tearing it up. You can't quit until we're two years behind schedule and $30M over budget.

Whelp, if Pentax won't do anything I guess it's up to us. Let's reverse engineer some cameras, bang out some firmware code, open source the darned things, and build our own K-new and truckload o' lenses.

Who's with me!?!?

Depends... I shoot a lot of kids soccer, and there I'm all over the place from 55 to 300 with the PLM. My most used lens after that is probably the 40mm limited, although I've used the 21mm limited quite a lot since I got it earlier this year. I've also had trips where the 15mm limited was almost glued on the camera.

And I think that if Pentax made a tiny 20-something mm WR LTD lens that would shoot to the top of my list.

I understand that you can tell. I'm sure I could discern some differences if I really tried. I actually have a decent stereo with a Marantz receiver that's pretty high quality, I ran my own cabling for my speakers and dedicated subwoofer. I'm no audiophile, but I'm probably in the 80th or 90th percentile in trying to get quality out of my audio. And I would certainly have to look at the file data to tell the bit rate and compression scheme of any music I'm listening to in almost all of my use cases. I'd have to try hard to tell the difference, it's not nearly as obvious as having a photo full of blow out highlights.

Although blown highlights are less obvious on a 4" phone screen, which is where most photos are viewed. Similar to how most audio files are listened to on a car stereo with a very high background noise level and varying quality of audio components.

Yes, I realize that I'm arguing that a lot of our photo discussions are pretty meaningless in real-world viewing conditions. And that's probably pretty true. Earlier this year I posted a couple photos of the same car parked by a mountain in Austria. One with a K-3ii and a 40mm limited lens, one with a K-30 and an 18-55 kit lens. It was extremely hard to tell the difference at web viewing sizes and conditions, and multiple long-time posters guessed wrong. One of the reasons cell phones have eclipsed many types of stand-alone cameras, and mp3s and streaming have overwhelmed other types of audio, is that they're largely indistinguishable from more pristine files for many or even most use cases. Sure, edge cases. Listen on a really good system in a quiet room with 22-year-old ears, or view really big photos and you can tell if you try hard enough. But that's not the norm.

It is possible to have a digital file so poorly encoded or compressed that it's immediately obvious. But I think those are edge cases. Most music is listened to in fairly noisy environments like cars and offices and houses full of people doing stuff. Not in hermetically sealed anechoic chambers on $30,000 high fidelity systems. As others have said, it's kind of like photography, where we argue about purple fringing and slight aberrations on 100% crops of 36 MP files while usually viewing on commercial grade monitors that max out at a few megapixels in resolution. For the vast, vast majority of use cases the difference between a pristine master audio file and the mp3 you just got off Amazon is almost completely meaningless.

You could remove the word "modern" and you'd be fine. I'd bet that (as a percentage of total movies made) there were more continuity errors in 1930 or 1950 or 1980 than today.

But they will die, except for the nostalgia market and a few other tiny niches. CDs have the same information as streaming or downloads, but in a very inconvenient format. I have hundreds of CDs, but almost all of them are in boxes in my garage, not touched in more than a decade.


At least with vinyl you can put on your black rimmed glasses and repeat the mantra that analog is better, and after a while you might believe it and get an actual dopamine release from your brain.

I'm sure that each of us here can name dozens of our friends and acquaintances who've been taken down in the prime of their lives by the EVF scourge. When will we wake up? Will no one think of the children? Will no one look out for the generations being raised by the blind and the maimed before EVFs are banned permanently?

That's spectacular. One day I'll have to step up from my popcorn popper roasting method, which has some limitations. But unfortunately I'm now getting more caffeine-sensitive in my middle age, and don't drink quite as much as I used to.

Here's a quick-and-dirty comparison of the Rokinon 500mm f/8 mirror lens and the 55-300PLM. Both handheld on static subjects. The Rokinon took a lot more tweaking in post, otherwise it was very flat and non-contrasty. The 55-300 photos were taken at 300mm, f/8, processed to taste and cropped to the same approximate field of view.

I think the 55-300PLM images are clearly superior, which shouldn't be too surprising comparing to a lens I bought for $30.

You could always learn to train the birds, or get to know someone who trains birds. Then you can get really close to them and get some incredible detail with a 55-300.

I have a Rokinon 500mm f/8 mirror lens I bought on KEH for $30. I haven't used it a lot, but so far I can't get results on par with a combination of 55-300 and heavily cropping. It's manual focus, so the odds are you're going to nail focus on that distant bird much more easily with a 55-300 PLM.

I could be wrong, but for birds on Pentax I don't think you're going to even approach anything as high quality and inexpensive as a 55-300PLM. The next steps up in quality are going to be vastly more expensive.

I buy green coffee beans online. I roast them in a converted West Bend Poppery II popcorn popper. Sometimes to a lighter roast, sometimes a bit darker, but usually not Starbucks-style nearly burnt. Then I make the coffee in either a French press or a moka pot. That's on the weekends when I have time.

At work it's a Bunn drip coffee maker with whatever Folgers or Chock Full of Nuts or grocery store brand coffee is in the coffee mess, made with water that's filtered but I'm sure it doesn't get all of the crud removed from 50-year-old military base pipes.

I always try to be careful extrapolating my wants and needs to others. I've had a K-30 with a pop-up flash for seven years and I might have used it seven times. But I've used the GPS on my K-3ii a lot. I could probably be a better photographer using more flash, but I'm betting I'd be happier with a small external flash and a GPS than a pop-up flash and the O-GPS1.

You may be right, I might be completely off-base here. But I do know that RawTherapee is free and open-source, I use it, I really like it, and it has some of the best Pentax-specific pixel shift support of any RAW development software. Darktable also has good support for Pentax cameras and files. Yes, there's a significant leap from a RAW developer to embedded applications.

As Bruce said in his last post, he wishes he hadn't mentioned Android at all. I think this conversation would be more productive if the focus was on "wouldn't there be some potential gains if at least some of the software/firmware in the camera were open sourced and a community of dedicated enthusiasts could attempt to innovate in ways that might be infeasible for a camera OEM's small engineering team?"

If open-sourced right now someone could be working on new features, bug fixes, updates, lens corrections, etc for Pentax cameras, even ones that Pentax no longer supports. I assume it's not done right now because of intellectual property concerns, and risk of people installing buggy or poorly-written software on their cameras and that reflecting negatively on the OEM.

I put the little plastic cap on the eyepiece when I was walking away from the setup, so none of the kids would be tempted to look in. But in a matter of seconds there was a wisp of smoke and a small hole was starting to be melted in the cap.
