After reading the article I came to conclusion that GAS is relatively mild side-effect of our hobby:)

Optech or Peak Design. Quality is similar, Optech seems to be more versatile system in terms of various scenarios it can be used in. Peak Design also builds its system, but they are slightly behind Optech. I use both systems, Peak Design for 'generic' K-1 configuration, and Optech for Mamiya RB and K-1 with Sigma 150-500.

If you are satisfied with image quality of KP, I think you don't need 28-105. Granted, image quality of FF is generally better, but in this scenario you have satisfactory quality with KP already. As you noted in original post, K-1 with 28-105 is bigger, heavier, and more expensive than corresponding APS-C rig.

I use both lenses and I can tell you what it means: 28-105 and 16-85 are very good all-round lenses for FF and APS-C respectively. It does not mean you get similar results - sensors are different and they require different lenses. Think of following question - 'I'm looking for very good all-round lens, what do you recommend?'. The answer is: 16-85 for APS-C, or 28-105 for FF. Similarity is in function and in ways you can use them, not in the quality of an image.

This is really good lens, I use it with K-S2. The sole drawback is its weight, it makes small camera front-heavy. Have fun with 16-85:)

Have you tried to clean lens mount? My K-S2 used to behave in the very same way, and cleaning of both surfaces of the mount (i.e. lens + body) solved the problem.

Depending on how winter in your area looks like, you may consider a battery grip - you would have two batteries installed instead of one, and you don't have to open the battery door in inclement weather. The trick is not particularly useful in dry and very cold weather, when it's better to keep a battery in an inner pocket, but I would definitely consider it when it's snowing, or the weather is damp and moderately cold.

I've got prism viewfinder and waist-level viewfinder with loupe* for Mamiya 67 RB, and I can tell you I have used prism one only once. There are two reasons: the prism itself weights almost 1 kilogram (2 pounds), and it has no metering. As per portrait mode, Mamiya has got rotating back, so it's not a problem. Left and right are reversed in waist-level viewfinder, what is problematic to some extent. For me prism viewfinder (with exception of the one from Mamiya:) is more convenient as I don't have to look at the camera from above, what is rather unnatural in most cases. The loupe, on the other hand, makes precise focusing easier.

I have quickly tested my 28-105, and 4" object fills the frame at minimal focusing distance and 105mm, and 12" does it at 28mm. I can take some sample pictures if you are interested. 28-105 is really good all-around lens, I can only second what DeadJohn wrote.

I've got EX DG, and at a first glance these pictures look surprisingly soft. However, I never tried to use my lens in 'pseudo macro' mode, i.e. when relatively small subjects are photographed from close distance. When used in proper 'tele' mode, it is one of two lenses (the other one is F 100/2.8 macro), which renders OOC pictures beautifully. I can test 'macro' mode next week if you are interested (I can do it with either K-S2 or K-1).

I'd say it's slightly more that 1/4 of a turn - like 100-120 degrees. As Paul has written, it's hard to tell because there are no hard stops.

Assuming that you had a fix shortly before the blackout, issues with long lock time are highly unlikely, as the camera obtained virtually all data already, and its biggest chunk (i.e. ephemeris and almanac) has quite long expiration date. Very mysterious case:/

Based on my experience with K-1, a minute is quite a short time for getting a fix. Please keep in mind that K-1, as far as I know, does not use A-GPS, and as such needs to obtain data directly from GPS signal. Due to low bitrate of the latter, it takes a while, the more the longer you have not been using GPS.

When I use Sigma 150-500@500, I would consider 1/320s to be rather long exposure, even with Sigma's image stabilizer. Moreover, deer's hind leg looks blurred to me, what suggest a movement. Last, but not least, grass and branches at the top look sharp, what is quite strange, as usually sharpness decreases to edges of a picture. If it were my lens, I would test it on a tripod with static subjects to eliminate hand shake, movement blur, and to verify for possible back/front focus.

Yes, and even if you create a picture in graphical application (like MS Paint), you will see pixels when magnification is bigger than 100%.
As texandrews wrote, one could use special applications (for instance Exposure BlowUp) to prepare a picture for a large-format print. However, you may find it simply unnecessary - here is why. In analog times there was simple rule of thumb - if 13x18 cm print looked good, one could enlarge it to any size. This is because people usually look at a picture from the distance equal to or bigger than diagonal of the picture. You can easily verify it with your TV set - it's rather uncomfortable to watch it from 10 cm:) Of course other factors, like colour calibration greatly affect end result, but this is entirely different story, related to processing of RAW files rather that preparation of large prints.

I've experienced similar issue with my flash - it simply stopped to work. I've tried to put new batteries, Eneloops, to tinker with battery door, but to no avail. I rarely use flash, so I decided not to repair it, but to keep it as parts donor.

Thanks! The cat initially wanted to take a look at the intruder, but later on ignored the hedgehog completely. I think such ending qualifies as 'happy':)
