One of the easiest ways to do this is to change to a fixed (aka prime) lens. Using a lens with only one focal length requires you to get up and check out your selected subject from different vantage points. Yes, it’s life in the photo slow lane, but who cares. Nature photography is hardly “breaking news”! When it comes to single focal lengths, I prefer something on the wider side of normal. That said, let’s assume that around 50mm (in 35mm equivalent) is normal so I’d go for something between 28mm – 35mm. It’s often easier to get closer than farther away, and shorter lenses weight less than longer ones so they are easier to hold in low-light conditions. Yes, everyone has a minimum hand-holding shutter speed but it differs from one photographer to another. While switching to decaf has been proposed as a way to extend hand-holding speeds, I prefer to look for any type of camera support, but that decision is, ultimately, yours.
I’ve just acquired a mirrorless camera that has a fixed 23mm (35mm in 35 equiv) f2 lens. How well will it work for me? Will I regret the purchase? Will the Nikon family be upset that none of them will be leaving the Carlson Camera Clubhouse? Check back in a bit over a week. I’ll have the answers then and will be glad to share them with you.
