I didn't use Dektol for film, I just broke the bulk packages down to smaller mix quantities.
At that time it was possible to buy 5 gallon tin cans of Dektol and D-76 for almost nothing over the price of one gallon mixes, so I bought the big tins and broke them down and put them in baggies.

How firm is the 6x7 film advance meant to be?

My 6x7 suffered T-Max induced advance failure. After I got it fixed I put several thousand more rolls through it without a problem, but yes, the advance is the weak point in the camera.
Be reasonably gentle and it will last a very long time. Advance the film with undue force or speed or as noted let the lever retrace too fast and you are asking for a repair.
If you note the frame spacing getting erratic the advance is in early failure.

I did something similar with chemistry when I was depending on my parent's largesse for hobby funding. I'd buy a big bag of powdered D-76 or Dektol and break it down into smaller quantities. I used a lab scale, but measuring by spoonful is certainly accurate enough.

Looks like it was taken with a wide angle lens pointed downwards a bit.
Perspective distortion.
You can avoid this by keeping the camera level at the expense of composition or you can adjust the geometry of the image after the fact in post processing.
I did a little Photoshop work on it......

If shake reduction isn't as effective as you would like you are stressing the system beyond it's limits.
You need to use good shooting technique to make it work.
This means both hands on the camera, a solid shooting posture, good breathing (I exhale slowly when shooting, I find it works best for me), and not asking more than the system can give you.

When Pentax first put SR onto a camera in 2006 I was able to handhold my A*600/5.6 with that camera. That was when I was in my late 40s with a 6mp camera. I tried the same thing a few years ago with my K1 and wasn't able to get really crisp pictures.
The difference? I'm now in my mid 60s and don't have the upper body strength I had when I was still slinging a hammer building houses (word to the wise: don't take on a construction worker in a bar brawl) and the K1 has a much denser sensor so it will show shake quicker.

Also, there are a few human frailties that will test shake reduction. If one is particularly unsteady shake reduction isn't going to be especially effective.

If your camera moves more than a few millimeters during the exposure shake reduction will fail, and that isn't on the shake reduction, that is on the user.

You should look at the size and weight of some of the Fuji Red Dot lenses. They are huge and heavy.

Here's a size example. The Fuji isn't a Red Dot lens.
From left to right, the Fuji 80/2.8 Macro, the Pentax 100/2.8 Macro and the Pentax DFA* 85/1.4.

I think what people complain about with the Pentax DA line up is that they have one lens in each focal length not 3. Their expectation for a full lens line up would be a full DA Limited line, then a DA line of cheap lenses and a DA* line of expensive ones.
Of course all they would buy is the cheap DA ones, but their expectation.......

It is.

If you like learning stuff, there is something for everyone. If you like compositional masterpieces, photography is capable of the best. If you are a techie, photography is as technical as you like whether you choose film or digital as your medium.

K1 II - not feeling the love anymore!
Posted By Wheatfield
Replies: 75

The K1 and K1II still do things other cameras can't do.
Astro tracer, for example, is unique to full frame cameras and only Pentax does it at all.
Other makers are now putting in IBIS and pixel shift. It took them long enough.

For me though, the real draw of Pentax is the lenses. I like the lenses.
Certainly they can be adapted to other bodies, but to no advantage that is of any importance to me.

How firm is the 6x7 film advance meant to be?
Posted By Wheatfield

Its a lot heavier than a 35mm. You are moving 4 times as much film twice as far with the same (more or less) motion. It should be smooth though. If it starts to feel like it's skipping for lack of a better word it needs service.
The 6x7 film advance is robust, but it should not be moved as fast as one would cock a 35mm shutter.

That old definition comes from what the human eye can resolve. Our eyes haven't changed all that much in the past 100 years or so.
As for has shake reduction become more effective, yes it has, but it has also had to to keep up with increased pixel density.
Even with shake reduction, I need to be a lot more aware of technique with my 40mp APS-C camera than I do with my 36mp full frame camera.
Shake reduction is reactive technology, not proactive. For it to be effective it has to react faster and more accurately as sensor counts increase since camera movement as slight as 1 pixel will show up as camera shake.

Raw vs jpeg

The raw image is saved as either a PEF or a DNG file. Technically both are revisions of the TIFF format, but they can be treated as a format unto themself.
If you specify the format as raw II don't recall if TIFF is an option on the K5) it will be saved as a raw or tiff file. If you save the image as a jpeg it will be saved as a jpeg and whatever customization you have specified to the camera is how the file will be handled.
In a nutshell, if you want to post process your file, save it as a raw file. That way you have everything from the sensor to play with. If you aren't into post processing, save the file as a jpeg and play with the custom settings until you find something that is a close match to your vision.
If you aren't sure, if the camera allows it, save as both so that you have the raw file to play with down the road.
Note that raw files are a lot bigger than jpegs and plan accordingly.

Cell phone service (AT&T and partners) in BC and AB, Canada?

My experience with cell service in the Rockies has been pretty good. Every now and again a mountain range gets in the way and the place I vacation in BC has very poor cell service (it's one of the attractions for me). I think if you are staying on the #1 you'll be OK presuming your American provider is playing nice with the Canadian network, all of whom seem to piggyback off of the same network.

If you are intent on doing any post processing raw is the preferred format as it is an uncompressed full information file.
Jpegs are a finished product which can still be edited but don't have the flexibility of a raw file due to compression, bit depth, and a potential loss of detail, especially highlight and shadow.
Also a raw file doesn't have to be saved as a jpeg after processing, it can be saved as any image file.
I save processed files as 16 bit .PSD which is native Adobe and is uncompressed and full image and if I am sending the images out, either for web display or for printing I size them accordingly and then save that as a Jpeg.

Post processing strategies will change from user to user, and is a very big subject, not something that can be covered in a forum post without writing an encyclopedia.

That idea has been floating around in one form or another for a couple of decades. It always turns out to be unviable vapourware.
The revolving door seems to be someone 3D prints something that looks like it might be something, launches a Kickstarter to raise funds which disappear never to be seen again and the whole thing fades into nothingness.
Rinse and repeat.

You can't use an LS lens and MLU at the same time.
IIRC with the 6x7, mirror up also stops down the lens and it is that action that trips the leaf shutter.

That's because you are giving 100% weight to a technology that wasn't exactly effective, reliable or even desirable to the customers that used TLRs until well into the 1960s, which is when TLRs started to fade from the market.
