Monochrome Monday: 22nd July 2019

Monochrome Monday travels back a couple of weeks to one of my walks testing lenses adapted to a mirrorless camera. In this case a 25mm f/1.4 CCTV lens.

The variegated Hosta leaves have been a regular test subject for the various adapted lenses but one variegated plant is growing next to a plant with plain leaves. The colour version didn’t really work for me so I tried a monochrome conversion and played with the contrast.

Lens-Artists Photo Challenge: Detail.

This is my contribution to the Lens-Artists Photo Challenge: Detail.

I thought about some of the photos of details and it occurred to me that two of the first ones I considered were taken about 40 years apart but with the same lens.

So here’s a selection of shots from my Olympus OM Zuiko 50mm f/1.8 silvernose I purchased in 1976. It’s called a silvernose because it has a polished aluminium ring on the front of the lens. This means that it’s one of the early OM system lenses and that it could be single coated rather than multi coated like modern lenses.

A walk with a 25mm CCTV lens.

An afternoon walk, this time with a 25mm f/1.4 CCTV lens adapted to fit a mirrorless camera. I quickly discovered that the lens has to be used wide open, when I stopped it down I could see it vignetting badly in the camera viewfinder. It still vignettes a little wide open and as the image circle produced by the lens barely covers the sensor there can be some interesting swirling around the edges of the frame.

Soon after discovering that the lens needs to be kept wide open the focusing mechanism started playing up. Initially the focusing appeared to be jammed, once I got the focusing collar to turn the lens would focus on close subjects but wouldn’t focus on distant subjects.

I continued on my walk as my testing was going to be mostly close subjects. When I got home from the walk I got the focusing mechanism working and think that I have managed to fix it.

Some interesting variegated Hosta leaves. One of the first shots taken with the lens before the focusing mechanism started playing up. The edges of the frame don’t show much swirling in this shot.

An afternoon walk, 18th June.

I have physiotherapy on Tuesday and Friday mornings. As the weather was nice I decided to go for a walk with the camera on Tuesday afternoon to continue exercising my leg and arm.

For the walk I used my oldest lens, an Olympus OM Zuiko 50mm f/1.8 I purchased with an Olympus OM1 in 1976. I also decided to keep the lens set at its maximum aperture, f/1.8, for all the shots.

The lens is one of the early OM system lenses know as silvernose (or silver nose depending on the reference) because they have a shiny brushed aluminium front on the filter mount. They’re often single coated rather than the multi coating used on modern lenses. My copy of the lens has had a hard life over the years, it was once submerged in Georgian Bay and dried out in an oven.

A small group of Dandelion seed heads. I didn’t spot the falling seed until I posted the photo on Instagram a day later.
