Nikon D810 camera - A 36.3 megapixel professional-grade full-frame camera which was the most expensive thing I'd ever bought back in 2014 (and probably still is). It still holds its own against newer cameras for resolution, ISO quality and speed, although my back will thank me for one day slimming down to a smaller bit of kit. Bar the really early shots, almost every photograph in my portfolio has been taken with this camera.
Nikon 14-24mm f/2.8 lens - Ultra-ultra wide angle for the biggest landscapes photos ever. It's my most used lens for landscape photography and is super sharp even at its widest. It's also fantastic for the sunbursts I have in some of my sunrises, for astro-photography and for getting every inch of space in the shot for interiors and architecture. Oh and it's another backbreaker - but worth it.
Nikon AF-S 24-70mm f/2.8 lens - This was one of the best mid-range zooms Nikon made when it was released in 2015. It still stacks up against newer lens models for sharpness and quality. I use it for most my none wide-angle work, be it street photography, more intimate landscapes, people shots and much more.
Nikon AF-S 70-300mm f/4.5-5.6 VR - My lens for wildlife photography. I'd say that practically all the wildlife shots taken in my portfolio were with this lens. The fact is has Vibration Reduction (VR) means I don't need a tripod for those quick shots even in low light, and the sharpness is so good that I can crop heavily into my images without losing quality. Sure, it'd be nice to have a 600mm superzoom that looks like a submarine, but the quality of this lens means I don't need it.
Nikon 105mm f/2.8 AF Micro - Nikon's best macro lens in my opinion. Amazingly fast shutter speed and crisp shots of small stuff. I love using this on flowers and insects.
Nikon 35mm f/1.8G - Great for portraits, street photography and produces a lovely bokeh.
DJI Mavic Air Drone Fly More Combo - A smaller version of the Pro and one that I can easily pop in my camera bag to take with me. I recently had great fun flying it through the mountains of Saudi Arabia. Fantastic video quality, short battery life.
Go Pro Hero 7 Waterproof Camera - So small but so reliable. Took it swimming with whale sharks in Mexico and it captured some really clear footage of me nearly sinking as I tried to keep up with them.
Bags & Tripods
Neewer Convertible Rolling Camera Bag – I finally succumbed to getting a camera bag on wheels rather than a rucksack. My camera kit above is so heavy that this bag is a godsend for everywhere except the desert (but even there it's got straps I can use to carry it). It's comparmentalised and fits all the gear I need in it, plus it passes the aeroplane cabin test.
Vanguard SBH-100 tripod with ballhead – A very heavy duty tripod that can hold any camera/lens combination you could put on it. Perfect for needing to have perfectly still, long exposure shots such as star trails. Not perfect for jogging with.
XC525 tripod with head - My good tripod fell off a cliff and died on impact in Canyonlands National Park in Utah. With only one camera shop anywhere nearby I had a choice of only 2 replacement tripods. I chose this one and 5 years on I've still got it. Lightweight and can be strapped to a camera bag. It's a much friendlier carry-round than the Vanguard, but lacks the stability for long exposures.
Lee Filters – I've got a number of Lee filters but the one I to use to smooth out waters and clouds is the The Big Stopper. Essentially a black, square piece of glass that sits in a holder in front of the lens, it allows you to increase the exposure time without letting more light in, thereby slowing down movement. It's also great for getting rid of moving people if you want an empty scene for street photography.
Adobe Lightroom – My photo library, meta-data adder and editor of all my images. It's simple enough for me not to swear at it and advanced enough to do pretty much everything I could think I'd need to do with my photographs.
Adobe Photoshop – I'm not sure I should even include this on the list as I can only think of one thing I have ever used it for. However, it does beat Lightroom for removal of complicated shapes in images or stacking shots for astro-photography, and I really should learn how to do that.
