Hi all,
I tried this cute little binocular today, on a field trip. The owner, an elderly lady, just recently purchased it and said that she was particularly fond of its
brightness and wide FOV. She had complaints later on the day that she didn't get the views sharp, so I asked if I could take a look. I'm not familiar with this model, and when I tried to focus I couldn't move the wheel at all.
It took a minute or two for me to realise that there's a focus locking system on the focus wheel, when I pulled up the wheel it unlocked with a click, and became quite useable, and easy to turn.
I then noticed the sticker 'focus lock' on the left barrel, which left me a little embarrassed and puzzled.
What is the function of a focus lock in a birding binocular?
Best regards,
Ronald
As a PS I would like to mention that at the time she bought the binocular, the salesman told her to keep the focus knob in the down position as to set it right for her eyes; since the diopter adjustment is a ring on the right barrel, I suspect the salesman thought the focus locking system to actually be the diopter adjustment system. His ill advice had caused the lady to struggle in the field with getting things sharp, not being able to focus with the lock on the wheel.
I was glad that I could sort things out for her, and she was utterly delighted with her now operative binocular, but it left me wondering about the feature of a locking device in a birding binocular.
