Choosing a lens is like finding the perfect pair of hiking boots. You need something versatile, durable, and comfortable enough for long walks. It was a journey, but I found my match – the Sigma 150-600mm for my Nikon Z50.
Before the Sigma 150-600mm – The Struggle
Before the Sigma 150-600mm, my photography was like hiking through a dense forest with a rudimentary map. My 70-200 kit lens, with its f5.6 aperture at 200mm, was barely making the cut. Small birds, my favourite subjects, were almost impossible to capture full-frame, let alone on the vast Lancashire fells.

Why Sigma 150-600mm?
Budget-wise, I had to find a sweet spot between quality and affordability, akin to choosing between brand-name boots and a lesser-known but practical alternative. After some research, the Sigma 150-600mm became the front-runner. It was popular, had been around for a while, and it fit my budget. When it arrived, I swaddled it in RealTree Neoprene wraps, the lens equivalent of a sturdy boot protector.

Lens Performance in Real-life Situations
The Sigma 150-600mm was my compass in the wilderness of wildlife photography. With its versatile range, I could capture anything from a friendly robin to a soaring hawk without switching lenses. This freedom significantly improved my photography and unlocked a plethora of new opportunities.

Any Downsides?
But, like a rugged hike, the Sigma 150-600mm has its challenges. It’s great for stationary bird shots, but capturing birds in flight can be a bit of a trek. I manage to get some decent shots, but there’s a pile of blurry ones for every keeper. It could be my technique that needs sharpening, or the lens struggling to find focus – probably a bit of both.
Also, the lens can feel heavy after a long day, much like a well-worn rucksack. The manual focus ring is too close to the body, which can be fiddly, and the tripod collar isn’t quite designed to be a convenient handle.

Do I Regret the Choice?
Despite its quirks, I’d pick the Sigma 150-600mm again in a heartbeat. It’s versatile, reliable, and has been instrumental in my growth as a wildlife photographer. It’s like a dependable compass – not always perfect, but it gets you where you want to go.
