On a recent 3 day off-track backpacking trip I decided to go lighter than usual: skip the tent and take just a tarp, take just the minimal food and leave the "gourmet" at home, and lighten my camera equipment.
I committed to have with me a set of 3 diminutive lenses from the Pentax-110 SLR system adapted to Micro Four Thirds: the set is lighter than one single vintage lens that I carried in the past.
There is however a challenge with those lenses: apart from being manual focus only, there is no iris in the lens to control the aperture but a simple wide-open value of f2.8.
On the longer lenses of 50mm and 70mm in particular I had to be very careful with focusing to get my subjects sharp. The payback was a lighter pack, more angles of view to choose from (from multiple lenses) and ultimately that look that my zoom modern lenses can't give me.

My friends Melt and Gill, also keen photographers, had more conventional lenses with them.

And this is what they were photographing

I came across this empty nest, so beautifully crafted.

I also used the 50mm lens paired with an extension ring of 10mm to get some close ups

and the 24mm with the extension ring to give me an extreme close up of lichen:

Running along on the side, some distance away, while my friends were hiking, proved more difficult to get a sharp image: I had to magnify my scene in the electronic viewfinder to nail the thin depth of field.

While rather versatile these lenses are not as universal as my modern auto-focus zooms. The difference that I find is in the look that I get from these lenses that were designed in the 70's for a film camera that was truly miniature. The 110 film however never really did give credit to their sharpness and re-purposing and adapting them to digital cameras unleashes the real full potential.
PS the display of this website however, by interpolating and compressing the original files, also dwarfs the sharpness of the Pentax-110 lenses; full size files are muuuuch sharper..
