Amazing shot of the Monarch caterpillar! Looks like it's nearing the stage when it will spin its chrysalis. Will you drive yourself crazy documenting that development? I could think of worse obsessions, and given your skill you should wind up with some amazing images.

Actually, I wonder whether autofocus is reliable enough to do use time lapse and automate the process...

What are normal stopdown preset mechanics for M42 Takumars?

Very happy ending! Thanks, especially Tim!

When I first saw Tim's reply, I thought we were talking at odds. Trouble is, there are TWO silver pins, the big one that I had referred to, and the tiny one recessed in the lens mount that Tim talked about that frees the AUTO/MAN switch. I didn't find it at first, but I cautiously screwed the lens onto the camera, and to my amazement the AUTO/MAN switch, and the lens itself, worked just as Tim said. After taking the lens off, I discovered the tiny pin by noting that screwing the M42 adapter on was enough to free the AUTO/MAN switch, but only when the adapter was nearly tight. Thanks, sergysergy, for your link showing the picture.

I suppose the lever that the aperture ring moves in the slot in this Takumar was only designed to tell the (film) cameras the aperture settings, unlike the lever in later cameras that additionally had a stop-down function.

Also, although admittedly not designed for this purpose (like an actual preset ring on say, the 28mm shift lens), you can sort of use the AUTO/MAN switch as a preset: choose your aperture with the ring, then switch to AUTO to focus, and then to MAN to stop down to meter with the green button.

Finally, I HAD found Adam's article, and in fact had found it very helpful previously when trying to set up catch-in-focus for manual lenses. There were many other similarly helpful descriptions on how to set up the camera, but I had a hard time finding much about mechanical interlocking and functionality of the lens by itself.

So thanks very much for your replies; you saved me major embarrassment!

Are you importing both JPG and DNG versions of the same image into LR, and, if so, do they look similar to each other, or do their exposures, and LR histograms, also vary between each other?

You can find very small digital humidity meters at Ali express for under $1.50 each, including button battery. Listings change all the time, but to show what I had in mind, here's a recent finding:

Digital LCD Indoor Convenient Temperature Sensor Humidity Meter Thermometer Hygrometer Gauge Weather Station Monitor Hot Sale-in Temperature Instruments from Home Improvement on Aliexpress.com | Alibaba Group

FWIW, I once bought 16 for 1.18 each. Toi check them, I put them in a closed box, and after leaving them overnight, they all read the same, except for 2 that deviated by 1% of from the others.

You can also find reusable silicon dessicants there, also for ridiculously low prices.

My little KP's Impression

Thanks, Tamanagi, for the interesting and helpful impression.

People have been discussing KP size a lot, but few have mentioned the current Pentax SLR with the smallest frontal section, the K-S2 (closely followed by the K-70). This camera is significantly smaller than the KP. Placing the KP mode wheel on the left to allow additional controls to the right of the viewfinder is what makes the biggest difference. This doesn't count handle/grip extension, but the K-S2 grip was originally criticized for being too small anyway. To me, it feels fine, essentially identical to that on the "larger" K-50.

The K-S2 kept me from getting a four-thirds system for some time, since I could shoot it unobtrusively at family events with the 15mm limited attached. Camera size was never a problem, but the shutter noise was distracting. The silent electronic shutter on my GX8 is one of my favorite features: you can photograph all you want without disrupting conversations. It's intriguing that the KP itself has an electronic shutter. Apart from discretion, the other main difference between the 2 systems is lens size, which, for lenses with apertures 2.8 and larger, is not that different. Wish I'd seen the KP a year ago.

Wanted K50, now thinking KS2

I actually bought both of these, for about the same prices (but new K-50 wo lens). They are both great cameras, but the swing-out viewfinder on the KS-2 can be amazingly useful. It will NOT be important if your style is mostly hand-held with the camera in front of you or up to your eye. But if you work from a tripod, you can swing the finder out to a conveniently-viewable position. Without contortion, you can use live view to compose and critically focus before shots, and afterwards, its much easier to zoom in to critically inspect your results. Off-tripod, the viewfinder lets you compose conveniently when you want the camera near the ground, pointing upward at some angle, or in some odd position for whatever reason. And the KS-2 is much more selfie-friendly, not just because of the viewfinder, but it even has a button arrangement for that purpose.

Photographically, the main weakness of both of these is a limited buffer for burst shooting, so the K3 is something to consider if that's very important. I do use the KS-2 in burst mode routinely, just have to remember to take a few at a time; but even the K-50 is noticably better.

Holding the cameras, I find the feel to be nearly identical, despite the more planar body features of the KS-2 (I prefer the K-50 body aesthetic), and despite the different thumb rests. I find the LED's on the KS-2 (restrained from the KS-1 light show) to be helpful. One other difference is that the back AF button is right under your thumb tip on the KS-2, making it much quicker to operate in for back-button focus (with the aperture button focus disabled) than on the K-50. And the sensor on the KS-2 (wo anti-aliasing filter) is more advanced, although you'll need sharp lenses and near-perfect technique to see this difference.

If you get the K-50, you may find you wished you'd spent the extra money for the tilt out screen; that's what happened to me. I'd be thinking very hard if I were you: the viewfinder may not matter to you and the K-50 deal is great. .

Full Frame a Mistake?
Posted By eyeball

Although Tony Northrup tends to be sympatheitic to Pentax, his video criticism totally missed on several points.

Reasons for FF: One reason for Pentax going full frame is that there were so many users clamoring. My own reason had to do with my full-frame film lens collection, which I impatiently wanted to use, especially the wider angle ones that became telescoped to inconvenient lengths (unlike many, I find the range between 35-60mm an uninteresting dead zone.) And the large number of good, compatible vintage glass was a sort of selling point for the brand. Apparently along with many others, with the release of the K-1, I feel that Pentax/Ricoh has kept faith. TN's discussion totally missed this: the K-1, with its low price and exceptional feature set, was an arguably important marketing device, not just for new users, but for veterans who were getting ready to bail for lack of FF (there have been a few here).

In the meantime, I've picked up several APS bodies which I've come to enjoy, especially given the flexibility of digital post-processing. I joke that I could take a photo with the bottom of a beer bottle and make it come out ok with enough work. But over time, I've come to understand and respect APS-C as a serious format in its own right, and though I'm still looking forward to getting a K-1, it's now mostly to run wide angle primes and shift lenses. The image improvement that the larger sensor will provide is now more of a matter of curiosity than necessity.

No Lens Availability: Because you can develop a familiarity with a single focal length in a way that is too confusing for zooms, I prefer shooting primes when possible. In this regard, there are plenty of vintage lenses available, belying the criticism that lenses are unavailable for the K-1. My own experience with vintage lenses is that there are a good number of primes that provide high quality images on 20 MP K-S2, which is in some ways more demanding of spatial resolution than the K-1. TN's criticism of lens supply mistakenly ignores the availability older glass. Zooms, of course, are another story. Since aspherical elements and exotic glasses are now commonplace, the quality of modern zooms is unmatched by earlier versions.

Pentax also has a unique reputation for compactness, not only in its prime lenses, but in camera bodies as well. Pentax crop-sensor camera bodies are already relatively compact, but the main bulk in a camera bag has to do with the lens complement. For travelling, the larger size of the K-1 and its lenses is a disadvantage, especially if you use zooms, but it is possible to assemble a kit of small primes, limiteds and vintage, which are less bulky than other brands even in FF. However, while I've been toying with the idea of going to M43 for trips, I'm finding that I can do well with a couple of crop bodies with a 15mm/f4 limited and a 50mm/2.8 A macro, and with a 135mm/2.5 in the bag. A mix of new and old that I doubt TN would have considered.

Divided Resources: The camera is planned for a four year lifetime, which leaves resources for further development of APS-C, as we're seeing with the K-70. Pentax still needs to improve focusing, and tweak its sensor performance. The D500 has set new standards, which Ricoh will be matching as technology improves. (Movies also, for whomever is interested). But I'm thinking there will be APS-C advances over those next 4 years, which will not only increase performance of the newer crop of crop cameras (couldn't resist ;)), but will likely be incorporated in next-generation FF. And will we see the FF tilt screen on the next APS-C flagship? Instead of spreading resources too thin, I see the possibility for developmental synergy. I think TN missed that too.

TN just isn't Pentaxian.

Wanted K50, now thinking KS2

The KS-2 came yesterday and I played with it a little bit, so I'll pass on my first impressions. It's almost a clone of the K-50, with an added articulated screen, and a 20 MP sensor upgraded from the K-50's 16 MP. Handling-wise, the cameras are practically the same size, the narrower width of the KS-2 being due mostly to its square rather than rounded edges. You can actually argue that the grip on the KS-2 is slightly larger in terms of finger wrap than the K-50; they're both a little small, but not horribly so. Buttons are placed in nearly the same places, those on the KS-2 being a little closer to accommodate the bit of extra room taken up by the flip-out screen. The KS-2 also has a wi-fi button that doubles as a shutter release for selfies, has a few more jpeg processing options, and has a specialized movie position on the power switch. You'll have to decide whether the differences are worth the ~$300 vs ~$500 going prices. For me, the articulated screen was the one and only compelling feature. I hope to put a Rokinon T/S lens on the KS-2 and see how that works out, but even if I find something worthwhile, I won't be reporting on it for a few days, and it will be in another thread.
