Modern cameras integrate 100 years of photographic technique and knowledge and permit a novice to take perfectly exposed images. "Art" depends on the content of the images, though.

Indeed, it is a very good lens, selling for 500 - 600 $ used on eBay.

I'm not sure about that. I know exposing these yellowed lenses to sunshine reduces the inherent color but I don't know how they compare with the color rendering of newer models. Some used the older yellowed 105's with Black & White film with great success as it was like a yellow filter was used to darken skies slightly.

The 55-100 mm f/4.5 zoom and the 75 mm f/2.8 AL are awesome lenses in their own right. The 75 focuses very near and permits very nice close-ups. The 55-100 mm zoom is really good and affords a lot of versatility on the 645Z. Being very rare and highly sought-after, the 75 mm f/2.8 sells used for around 2500 $. The zoom is almost totally unknown and sells used for peanuts at around 350-400 $ on eBay. Older P67 105 mm f/2.4 used radioactive thorium in the glass formula and became yellowish-greenish over time, giving them a color cast in color pictures. Late model 105 mm are totally clear and give true-to-life colors.

I have 13 P67 lenses. They all perform splendidly on my 645Z digital.

Some were rather "ordinary" on film with a 67 II (like the 45 mm f/4 or the 90 mm f/2.8) but fare better on a smaller 33 X 44 mm sensor. Out of my 13 optics, my 3 best are in order 1) late 55 mm f/4 2) late 75 mm f/2.8 and 3) late 105 mm f/2.4 ("late" doesn't mean they are dead, it means they were the latest issues before Pentax film 67's went out of style).

The 105 mm is a "normal" on a film 67 (lens factor being 2.1 X), equivalent to a 50 mm on FF. On the 645Z, it acts as an 85 mm short telephoto. It is a "powerful" lens, with high resolving power, super deep contrast and totally impervious to flare or ghosting. Only drawback is the minimum focusing distance is rather longish at 1 meter.

The lens is all-metal, built to last a lifetime, substantial without being heavy. Older copies sell for 400 $ on eBay, newer copies (with rubber focusing ring) may fetch 800 $ or more but the lens is really worth its money. Some use it wide-open to totally blur the background like in portrait photography. Personally I use it @ f/8 in landscape imagery to make sure the picture is absolutely sharp from corner to corner.
A wise investment overall.

K3 + DA* 50-135 mm f/2.8 handheld. 135 mm FL brings us close to the shining wetlands bordering the river. No ghosts, no veiling flare, very good performance in these demanding conditions.

This lens was stored unused for a couple of years. I had forgotten how good it was. I was awed by these results and I find myself so stupid for not using it more.

This evening was particularly "delicious". I almost never get out of the house because of COVID fear. But I took a drive to the shore and saw a really low tide as the Great Lakes and the St Lawrence are at record minimum levels. We received almost no snow last winter and this spring has been exceptionally dry, so the river discharge is highly reduced. There was a lovely pungent wind bringing odors like you smell near the ocean ("Varech", we call this, French for seaweeds). The day ended past 20h30 as the Solstice will happen very soon. Indeed this looked like a piece of paradise.

Good to know, Theuns. I always close my apertures somewhat so I will give it a try at various "larger" apertures. Maybe I missed the sweet spot completely without knowing. Now, trying to find it in my stuff ...

I almost never touch colors, hues or tints. I lighten and sharpen a little. I set the camera's Color Palette to "VIBRANT".
