Should I Upgrade My Camera Gear?

When it comes to gear, I am unashamedly obsessed. Unlike some photographers, I love talking about the tools of our trade. And I must admit, I suffer desperately from GAS (Gear Acquisition Syndrome). I don’t know what it is. Let’s think on that for a second…

Perhaps, I’m naturally drawn to what’s quantifiable. Perhaps, I’m made to marvel at impressive specifications and the promise they make to set me up for success. Perhaps, it’s a desire to harness controllable factors in pursuit of perfection in a world that is anything but predictable.

When deciding to part with cash, it boils down to a question of WHY? What’s missing? What will this soon-to-be-purchased piece of tech give you that your existing equipment does not?

Rule 1: upgrade when your current setup no longer serves you.

I recently upgraded my camera body. I had started with a Nikon D3300 (entry-level camera), progressed to a D7200 (enthusiast-level camera), and for want of a more sophisticated autofocus system, amongst other features, I became the proud owner of a Nikon D500 - a professional-level DSLR. These were logical, linear steps towards a system that met the requirements of my ambition.

Reminder: investing in gear won’t make you great.

Don’t forget, gear is mere a tool. You are the photographer! A top-of-the-line camera will fail to produce outstanding images whilst it’s sitting on a chair with nobody touching it. As a beginner, don’t overwhelm yourself with impressive features when you have no clue as to their significance. For example, 10 FPS (frames per second) is meaningless when you have yet to produce a single frame in focus. Slow down and think about what you need, not what you want. I could buy myself a wonderful set of spanners. But believe me when I say, you wouldn’t want me as your car mechanic!

Time for a new lens, me thinks.

Until now, my lens for wildlife has been the Sigma 150-500mm f/5-6.3 APO DG OS HSM. Recently, I decided to part ways with my old friend and trade her in for a younger model: the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary. There’s some absolute bargains to be had online.

So why choose the latter over the former?*

The Sigma 150–600mm Contemporary wins out over the older Sigma 150–500mm for most photographers for several clear reasons. Below are the practical advantages you’ll notice in real-world nature and wildlife use.

Key improvements and benefits

• Greater reach

  • 150–600mm vs 150–500mm gives an extra 100mm at the long end. That extra reach matters for distant birds and shy mammals, letting you fill the frame more often without cropping or disturbing wildlife.

• Newer optical design

  • The 150–600 Contemporary has updated glass and optical formula that improves sharpness, contrast and control of aberrations across the zoom range. Expect cleaner edge-to-edge performance, especially at longer focal lengths.

• Faster, more reliable autofocus

  • Updated AF motor and algorithms deliver quicker, more accurate focusing and better tracking of moving subjects. This is particularly valuable for flight shots and erratic wildlife behaviour.

• Better image stabilisation

  • The Contemporary generally provides improved optical stabilisation over the older 150–500, allowing slower shutter speeds handheld and steadier shots at long focal lengths — useful in low light or when shooting from hides.

• Improved build and ergonomics

  • While still relatively lightweight for a 600mm-capable lens, the Contemporary offers a more modern mount design, better handling, and a more balanced tripod/monopod experience. Controls and hood design are refined compared with the 150–500.

• Weather-sealing (on later versions)

  • Many versions of the 150–600 Contemporary include dust and splash resistance that the older 150–500 lacks, offering more reliability outdoors in unpredictable conditions.

• Compatibility with extenders

  • The Contemporary generally handles 1.4x and 2x extenders better, retaining usable AF and image quality for extended reach when you need it. (I don’t use teleconverters…in fact, I recently sold my 1.4x extender to MPB)

When the 150–500 might still be relevant

• Budget constraints

  • If price is the primary concern, used or discounted 150–500s can be attractive. For casual shooters who don’t need the extra 100mm or the latest AF/stabilisation, it remains a capable lens.

• Weight and simplicity

  • The 150–500 is slightly lighter and simpler; some users prefer that if they prioritise minimal kit.

Summary recommendation

For nature and wildlife photography, the Sigma 150–600mm Contemporary is the better choice: extra reach, improved optics, faster AF, better stabilisation and more robust handling make it a more capable and future-proof tool. Choose the 150–500 only if budget or minimalism are overriding priorities.

And there you have it.

Go glass or go home.

Investing in good glass should be the most important consideration for serious photographers. When I first started out in photography, it amazed me how lenses were often more expensive than camera bodies. I can now see why. It’s almost impossible to buy a “bad” camera these days. But sticking a budget lens on a premium camera body is a bit like sending a full team of Premier League players onto the pitch but only allowing a toddler to take a strike at the net. It’s all in the final shot.

Coming soon: my new lens will arrive before the start of next week. I’ll be excited to share the resulting images of my first few outings including a trip to the Farne Islands in May!

Just off the Northumberland coast, the islands are home to 200,000 seabirds—including puffins —and a large grey seal colony - the perfect road test. Stay tuned!
