The "non random grid pattern" did appear on some of my night exposures with the original K-1.

No. The sharper the better. Software allows you to "unsharpen" any image at will. In bye-gone "film" days, sharpness could be a problem since numerical image treatment was unknown. And one could ...

In my experience, the 24-105 is the best mid-range zoom I have used so far.

With the advent of the K-1 MK II and the possibility to do a hardware upgrade of the K-1, it is improbable that the original K-1 will get any further firmware upgrade. I do hope I am wrong.

The 24-105 is excellent. I now use it exclusively. It does have some vignetting and distortion at the short end - and that is perfectly corrected by the corresponding camera profile available with ...

Sorry for the idle fantasy ridicule...

……………………………………………………………. ……………………………………………………………. There has been much discussion regarding - what seems to me - a marginal, if not insignificant, upgrade of the original K-1. Seen from a "cynical" ...

You probably have not corrected for Camera Profile. That would remove the slight vignetting apparent in your photo, and make it even better.

What you show is one of the reasons why I sold my 24-240 and got the 24-105. The latter is also (somewhat..) lighter and more compact and goes to F4 throughout. Also, I like to push contrast for ...

I no longer have the 24-240. Neither do I have images taken with it of the same subject as below. But here is one of the first test images I took with the 24-105 and a crop at centre. The 24-240 ...

I had, and extensively used, the 24-240 with a A7II. It was quite decent but required some post-processing and sharpening. The A7II had a 24 MP sensor - as also the A7III (albeit with a modern ...

Does that mean that the original K-1 will no longer have any firmware updates ?

They have cutters ready for your bag… But Macchu Picchu is magical and beautiful. My best wishes for your experience.

That is the most sensible - and most pragmatic reply!

My interest is mainly landscape and nature photography. The upgrade is not significant in that context and does not justify the cost. If something like a "Mark III" with new sensor, for example, ...

The 24-105 is very good, and does justice to the high resolution of the A7rIII. I use it almost exclusively on that body. Also, a zoom reduces the risk of getting dust on the sensor (the E mount is ...

Nice journey ! Watch out for camera thieves in Cuzco ! ...

I used almost exclusively Kodachrome before digital was available. The best results were with 64 ASA. The later 200 ASA were grainy and the colours less saturated (i.e. if one gave importance to ...

That's it. More pixels - the lens puts the limit. Less pixels - the sensor limits definition. A lens that outperforms the sensor will not show better. But it will justify a better sensor that will ...

That is my experience. So - I sold my 24-240...
