Here's my X-T100 with the Fotasy Pentax DA > Fuji X adapter and the DA 40XS lens. Quite a compact kit!

If I understand what you're asking...
From what I heard from another person using the K&F adapter, it is clicked. I.e., you can close down in steps on the adapter. (Steps are apparently ~ 2/3 - 1 stop each)

I purchased the cheaper Fotasy Pentax DA > Fuji X adapter, and it is clickless. That might be better for video. Otherwise with my DA lenses, I'm guessing how much I'm stopping down, and each lens is different.

I've had more time to play with the Fujifilm X-T100. Some very nice things and some frustrating/annoying things...

With regards to using it with my Pentax lenses, I discovered that you can get all sorts of weird distortion if you used the electronic shutter. Using the mechanical shutter is necessary.

I'm using the Fotasy Pentax DA > Fuji X adapter. It does not have clicks to close down, so I'm always guessing at how much I've actually closed down on the DA lenses. It does work much better using lenses with aperture rings.
Focusing using peaking is easy, but it is important to use the focus magnifier. It works fine for me using the electronic view finder.
The camera does a great job with SOOC JPGs, but that is mainly the case with the Fuji kit lens. Between adjustments closing down and shooting at -2/3 EV (since the Fuji tends to overexpose during daylight shots), I have run the following through LR to touch things up.
The pics are all from a little trip we took to West Virginia

First three are all using the DA 10-17 FE. The lens and adapter are heavier than the camera, but it is still a rather compact kit. The first two are from Spruce Knob (highest point in WV) and the last is from Seneca Rocks.
Last shot using the F35-70 lens, at f5.6, I believe.

@Jonathan Mac: My Fotasy adapter doesn't have clicks. (Maybe that's better for video?) I've since discovered that K&F does have clicks, but I can't find a K&F one on Amazon. I see they are on eBay for $37. (I paid $20 for the Fotasy.) I'll have to decide whether to keep the Fotasy or not, but I would prefer clicks.I see that Adorama has a Kipon one for $85, but it doesn't say if it is clicked or not. B&H has a Vello for $56 and a Novoflex for $211 (!), but it's not clear whether those are clicked or not.
Thanks for your comments.

While I'm at it... Here are SOOC pics with X-T100. Only thing I did resize down.

This one is using the 15-45 kit lens and the red filter.

And here's one using the X-T100 with the Fotasy adapter and the Pentax DA 40XS. That combination is smaller (though a bit heavier) than the 15-45. It makes for a great walkaround, especially because the 40XS doesn't need to be closed down much to get sharp pics.

I received the Fotasy Pro Pentax DA K Mount lens to Fujifilm FX Mount Camera Adapter today. ($20 on Amazon)
Attaching the lens to the adapter and the adapter to my X-T100 body is very firm. No looseness, and if anything, a bit tight.
I checked out two lenses today: DA 10-17 FE and DA 16-85. The former is the one I was planning to use with some regularity. The latter was used as part of a comparison using the lenses on the Fuji and on my K-3.
The adapter adds about 3cm to the overall length of the lens. It's still rather compact compared to putting the lens on the K-3, but the adapter and DA 10-17 weigh about as much as X-T100 and the 15-45 kit lens!
I used the menu (Shooting Menu #4) to "shoot without lens" and set the MF Assist to Peak > Red (high). You can also input a specific focal length. There is no IBIS, but it is a handy way to set an odd number to identify a lens. (E.g., I set it to 49mm to designate that I was using the DA 16-85.)
As for shooting, I moved the adapter all the way to the Open position to manage focussing. The peak indicators work well, better on the LCD but also well enough in the EVF. The best way I found was to use the EVF and the magnification feature. With this, I was able to nail focus quite well.
The trick, however, (which will require more experimenting), is that you're just guessing when you try to stop down the lens using the adapter ring. It appears that it stops it down very quickly. I.e., just a tiny fraction of a turn probably moved the DA 16-85 from wide open to f8. (I'm guesstimating based on the shutter speeds and ISOs when comparing the same shot using the Fuji and the K-3.)

If anyone knows of a better way of managing the f-stop, I'd appreciate knowing.
As for the images...

The X-T100 did as good and usually better than the K-3 in almost all my tests. And that's with me shooting at wide open and otherwise unknown f-stops. In line w/ its reputation, the Fuji JPGs are excellent with more clarity and pop than the in-camera JPGs of the K-3. After some typical, light processing of the RAF and DNG files (setting levels, sharpening), the Fuji pics still just looked a little better. If I understand things correctly, the ~40MB RAF files are uncompressed RAW files and the ~30MB DNG files are compressed, but there seems to be lots more detail in the images.
I am not giving up on my K-3, however.
  • I was able to shoot at 85mm in decent light without motion blur on the Fuji. I don't know how much of a longer telephoto I can shoot handheld without image stabilization.

  • There is a difference in noise in the images. I'm having trouble saying which one is less noticeable or easier to clean up, but my sense is that the K-3 will do better in low light and higher ISOs.

  • The K-3 and DA 16-85 is weather resistant, and that's important at times.

  • While I've figured out ways to get geotagging data on my K-3 images (using a GPX file), the geotagging on the Fuji using the Bluetooth on my phone is proving to be excellent.

In any case, putting my Pentax lenses on the X-T100 is going to work out very well, I think. I still want to see how things go with longer lenses and some of my older lenses w/ aperture rings so that I don't need to use the aperture control on the adapter. And as I mentioned above, if anyone knows a good way to gauge the aperture settings with the Fotasy adapter, I'd be grateful.

Getting the X-T100 depended on me now selling the K-30! I will indeed put the Fuji 50-230 on my list, but I'm still firmly in Pentax land. In the interim, what I'll probably do is get the $20 Pentax DA > Fuji X adapter. That will let me use my DA lenses, and I do have the DAL 55-300.

Fujifilm X-T100 first impressions from a Pentax shooter...
I recently acquired a used X-T100 with the 15-45 kit lens. I've been carrying around a K-3 as my main body (usually with the DA 16-85) and a K-30 (usually with the DA 10-17) as my ultrawide second body and backup. Depending on the situation, I might also have some of: DA 21, DA 40XS, a fast fifty, DAL 55-300. For general purpose hiking when I want to go light, I'd use the K-30 with the 18-135.

I got the X-T100 to replace the K-30. I wanted something smaller/lighter. I tend to shoot wide, so the 15-45 sounded like a good walkaround option, and I figured I can get the proper adapters to use my old M42 lens and my DA ones. My thought was to use the K-3 with the 16-85 as my primary body, and I have had great experiences with that combo. I would use the Fuji with the 15-45 for street shooting and also use it as a second body with the DA 10-17 for ultrawide.

Things that I dislike or am getting used to:
  • It's taking a bit to get used to the button locations. Finding the wheel on the back is especially hard without looking.

  • I simply had to turn off autofocus on the touch screen (drove me crazy accidentally touching it and moving focus point)

  • I often lock the back array of buttons around the menu button, since it is too easy to bump them.

  • The camera is a bit pokey. I mainly do stills so it's not really an issue for me. (I haven't tried the oft-criticized video.)

  • It is not weather-sealed.

  • I do wish it had in-body image stabilization so that I could use my old manual lenses with more confidence.

  • The Fuji RAF files are huge. (~40MB)

Things I'm liking:
  • It is indeed much smaller and lighter.

  • This is my first camera with a tilt/turn LCD, and that's very nice.

  • The electronic viewfinder does the job for me. I like that the electronic level is a line across the screen. (The little bars on the bottom on my K-3 and K-30 mean I have to look away from my focal point, and that's been awkward at times.)

  • I'm shooting in Aperture mode and set the multipurpose dial to change exposure and the ISO button to set up some regularly used auto settings. It's also been best to just use AF-S.

  • I don't mind the PowerZoom of the kit lens. When I'm shooting with AF, the front ring works as a zoom ring. (It's a manual focus ring in MF mode.)

  • I shoot RAW with my Pentax and RAF+JPG on the Fuji. Fuji does a really nice job with JPG output. I won't feel much loss at times if I'm doing less serious work to just shoot JPG.

  • The Fuji RAF files have the Lightroom lens profile included in the file. One less step of correction.

And what about the images?
My K-3 is noticeably better than my K-30, and I was hoping that the X-T100 would be more like the K-3 than the K-30. It is. The X-T100 is a clear step up from the K-30.

In comparing the K-3 with the 16-85 and the X-T100 with the 15-45 over the same range..
  • The K-3 has 3.5 stops of stabilization. The 15-45 has 3 stops, but I'm getting less blurry results shooting handheld in lowlight with the Fuji at same focal lengths.

  • Fuji tends to blow out highlights more (and I'm using -.3EV), but I need to play with it more.

  • Do note that the 16-85 f3.5-5.6 is faster at 45mm at f4.5 than the 15-45 f3.5-5.6.

  • At the wide end (15/16mm), it really pains me to say that I get better results with the Fuji. They are similar in the center but that little Fuji kit lens does better at the edges under a variety of f-stops but mainly f8. The K-3/16-85 does a slightly better job at the 45mm end. (This is after doing typical and similar postprocessing work in Lightroom.)

  • It's clear that there are different sensors and how they are working even though they are both 24MP APS-C. The Fuji does seem to pick up finer details. (I'll have to do more testing w/ Pentax primes to see if it's a lens issue and not a sensor issue. I'm just figuring for now that the DA 16-85 should be able to stand up to the 15-45.)

  • The most noticeable difference is colorcast, especially with greens. Pentax tends to blue, Fuji to yellow. I see benefits/drawbacks of both depending on situation, and such things can be adjusted with the RAW files in LR.

  • I'm trying to describe the different types of noise in images. The K-3 has a much larger dynamic range, but at similar ISOs (e.g., 1600), there may be more noise in the Fuji images, but it's finer and mainly luminance noise that can be fixed. I.e., except in the lowest light situations, I think I'll be fine with the Fuji.

BOTTOM LINE: I'm really impressed with the X-T100 and the 15-45 lens. It's exceeded my hopes. I can't afford to buy more Fuji lenses, but now I'm wondering whether I should use the Fuji with 15-45 as my main body/lens and use the K-3 for the DA 10-17, DAL 55-300, and my other special use lenses.

Planning a trip where my K-3 will be main camera, usually with the DA 16-85. I'll also bring along my DA 10-17 FE, the 40XS just because it's so small (and maybe the DA21 too), a fast fifty for low light, and then probably my DAL 55-300 for telephoto.

I want to have something small and lightweight to carry along. (Smaller than my K-30) In terms of features (at least APSC...) and what I can afford, I'm looking at the Fujifilm X-T100 with the kit 15-45 lens. With the appropriate adapter, I figure I can use my Pentax lenses too.
I'm looking for anyone have experiences w/ the X-T100 coming from a Pentax background, and pics using Pentax lenses. (With what adapter?)

Thanks!

Help me think... K3ii or KP or M43 or...

I'm looking, if possible, for a smaller camera that still delivers quality comparable to my K-3 and for which I can use my Pentax lenses and that I can acquire (used or new) for around $500.

Thanks to the input from you all, I have at least eliminated any M43 camera and want to stay w/ APC-C at least. I had also been thinking of a used K-3ii in order to have a camera with the same functions and layout as my K-3 with the benefit of geotagging, but the more I've thought about it throughout this thread, the more I've realized that smaller and lighter are preferred qualities.

I've been encouraged to consider the K-70 or KP as alternatives. They are not significantly different than the K-3ii in size/weight, but do offer other pros/cons.
It will probably come down to what shows up in the next few months in the right 'bang for the buck.'
Thanks again all for your input. It does help to 'talk out loud' as I think these things through.

I won't deny the appeal of a K-70 or KP, but I'd really like to get something smaller than the K-30 I already have. Compared to the K-30, the K-70 is not much help. (cf here) The KP is slightly bigger and heavier than the the K-70. The Fujifilm X-T100 is noticeably smaller than the K-70 (here) and even smaller and lighter than a K-01 (here).

Hmm... I must have missed seeing your K-3II...
Yes, I've decided that M43 is not for me. APS-C still is my preferred format.
If I could find a used KP for ~$500, I'd consider that, but the Fujifilm X-T100 I mentioned is still quite a bit smaller.
Thanks again, all!

I'm keeping my Pentax K-3 as my primary camera (usually w/ the 16-85 on it), but I'm looking for something smaller to use as a backup / street camera. And I want to be able to use my collection of K-mount lenses. I would be happy if Pentax came out with an updated K-01 with a viewfinder, updated APS-C, etc., but I don't think that's going to happen.

I've still been looking around, knowing that I still have a few months before getting another body.

How about the new Fujifilm X-T100 using my Pentax lenses? (Initial price is $600 body only, $700 w/ 15-45 lens - Hopefully prices will come down a bit in a few months.)

The Fujifilm is small, about half the weight of a K3, uses APS-C, and has both an articulating touchscreen and an electronic viewfinder.

It isn't weather-resistant, nor does it have in-body image stabilization.
It does video better than Pentax, however, especially if I pay an extra $100 and get the 15-45 kit lens. It has bluetooth and pairs w/ my phone so I can apparently geotag images along with viewing them.

If I get the right Pentax K > Fujifilm X adapter, I am apparently able to use aperture mode shooting, so I could use any of my lenses in manual focus.

I see a few people on this forum are using the more expensive Fujifilm X-T20 or X-M1 with their Pentax lenses, so it seems doable...

Am I missing anything? Other advice? Thanks!

Thanks, all! I was thinking about the K-70, but if I go w/ APS-C DSLR, I think I'd try to hold out for a used K-3ii. Maybe in a few months, and if Pentax announces a replacement for the K-3ii / KP, maybe one of them used will drop into my price range. Thanks again!

I've been perusing many similar threads, and I've run the Pentax DSLR comparison tool, but I'll appreciate any help as I think through things... (Also contributing to the monthly post total!)
Parameters:
  • I am thinking about a new body, and I have until ~November to get it.

  • I want to keep cost ~$500. I'm fine buying used.

  • I want to use the k-mount lenses I now have.

  • I am now using a K-3 and K-30. The quality of the images, lowlight functioning, and other features make the K-3 a perceptibly better camera for me. I would like to keep image quality at the K-3 level or better.

  • For my purposes, I want to have two bodies. For now, I've had the DA 16-85 on the K-3 and the DA 10-17FE on the K-30. I've tended to bring along something faster for museum work (DA 21 or DA 50) or something small for street (DA 40XS !) or something long if I anticipate telephoto (DAL 55-300).

  • Smaller size and lighter weight for the body are positives.

  • Weather resistance is a positive as is the ultrasonic dust removal (as compared to sensor shake).

All that said, I'm looking to upgrade my K-30 body. So, I'm considering:
  • K3ii used: It would be nice to have identical buttons as my K-3. I would use the GPS to tag locations. I like the image quality. Uses same battery as K-3. BUT: I'd prefer to have something smaller/lighter.

  • KP used: It looks like this would possibly offer even better image quality than a K3 and especially better lowlight performance. It is a bit smaller/lighter than a K-3. I think I would use the tilt screen at times. BUT: I don't know that even used it is available at $500; it uses different battery than K-3.

  • Go mirrorless? I'd be tempted to look for a K-01, but I'm not sure about image quality, and I do really prefer to use a viewfinder. I'm not quite sure where to even start looking at M43 or other mirrorless cameras. They certainly would be smaller, but do I lose any advantage in size if I need to attach an adapter in order to use my K-mount lenses? What should I be even be looking at to get similar image quality? If I go to M43, isn't that worse for wide-angle shots which are important to me? (I.e., my DA 10-17 on APS-C > ~15-25mm equivalent; on M43 > ~ 20-34mm) Is there anything else I should know about using K-mount lenses on mirrorless? (I'm aware that I'd probably lose autofocus on most.) Or do I give up on using K-mount lenses with a mirrorless and just use it for the times when I want to go light or telephoto? Is it possible to get a decent (used) mirrorless for $500?

As noted above, I have some months before a decision, but any insight/experience from others would be appreciated.

Interesting discussion... I started buying legacy lenses because they were so much cheaper than newer ones with similar quality, especially when I was trying to get a telephoto lens. I also determined that old primes are really the best bang-for-the-buck. [Though I do have fondness for an old SMC PENTAX45-125mm F4, the VIVITARSERIES 1 70-210mm f3.5 (Version 2), and a SMC PENTAX M75-150 f4, each of which I found for less than $30.]

After all is said and done, my three most used lenses are... DA 10-17FE, DA 16-85, and DAL 55-300. I can get better pics with the primes (though the DA 16-85 is really excellent for my needs), but I also have more throwaways due to focusing issues. There is something just nice about using an old prime, both in the experience of using a well-engineered piece of metal and glass and also in the rendering.

About that "normal" 50mm lens...
Posted By mgvh
Replies: 9
Views: 969
A fascinating article in The Atlantic entitled:
"How the 50-mm Lens Became ‘Normal’ - It’s often called the optic that best approximates human vision, but approximation is relative. An Object Lesson."

It's more of a history lesson describing why the 50mm became 'normal,' but it also reflects on other 'lenses' of perception we use. It does include a Pentax K1000 mention!

Tldr;... Here's the concluding paragraph:
Perhaps the 50-mm communicates an anxiety about whether an individual can understand someone else’s vision. Under the right circumstances, a 50-mm lens does create a perspectival relationship that, more or less, approximates the ways the majority of people see their everyday world. But it’s still relative. Mechanically, it’s relative to the specific apparatus to which the lens is attached. And metaphorically, it’s relative to all the social, emotional, or economic conditions that shape the everyday lives people inhabit. Perhaps we should be skeptical of the whole idea of a shared perspective. Rather, it is the difference between our lenses that leads to a better understanding of how machines, and people, see in the first place.
