Who doesn't like a good equipment post, nobody!
In my experience there are many types of photographers, for some the gear is everything, for some it means nothing. Some buy lenses and cameras to look at and never use, some couldn't care less and regard all photographic equipment as simply tools for a job.
I'm not entirely sure what group I'm in, mostly I regard all equipment as nothing more than tools but then on occasion I am extremely enthused by a piece of glass and can act irrationally in a shop full of beautiful lenses. Over the years I have used film and digital, medium format, 35mm and lots of smaller cameras, work often takes me to slightly dodgy places and as much as it would be great to set up a tripod, large format film camera and black cloth in the centre of Kabul, it's not going to happen!
On to my current kit list, I say current because i very rarely sell any photographic equipment so I have a large cupboard full!
I'm mainly a Nikon shooter, for no other reason than I love the files I get from the camera, I use Nikon D800's along with a range of AF and MF lenses both Nikkor and Zeiss. I also own a Sony RX1, for some of the places I work this camera is incredible! Compact, extremely quiet and arguably some of the best files available if you like the 35mm focal length, I don't travel without it, perfect for documentary style work.
Lenses, I am lucky that I have a few excellent lenses, the Nikkor 200 f2 is legendary and one of the most incredible lenses I have ever shot with. I use it for everything, portraits are beautiful but it also works great on landscapes.
Another favourite is the Zeiss 135 f2, a stunning lens, it is manual focus, fantastic to work with. As with the 200, it gets used for portraits and landscapes, I really enjoy shooting this focal length and stitched images have a huge amount of detail.
My dedicated landscape lens is the Zeiss 21 f2.8, another incredibly good lens, manual focus and often used with my Lee filters. It's also great for shooting aurora or stars at night, I use this lens a lot.
For general purpose shooting I use a Nikkor 50 f1.8 and a Nikkor 85 f1.8, these are cheap lenses but I'm always blown away with the detail they capture on the D800. They are pretty much disposable at the cost and so are always part of my travel kit.
There are lots of extra bits required to make all this work properly, I use a Hahnel remote for the camera, it's great for long exposures and setting up interval shots at night, it's also wireless so perfect for getting sharp shots.
I have used Gitzo tripods for years, my current carbon model is super light and extremely stable, I pretty much always shoot from it.
On top I have tried lots of tripod heads, my most recent purchase is a ball head and camera plate made by Acratech, it's great to use, extremely robust and may be with me for quite some time! I have a Really Right Stuff bracket on the Sony and also on the Nikkor 200 f2, everything fits together and works off the same tripod head.
I travel with a Macbook Pro, lots of memory cards and extra batteries for both the Nikon and the Sony, you can never have too much power! I own hundreds of camera bags, I'm always looking for just the right thing and it's difficult to find. I recently bought a Gura Gear Batterflae 26 and I love it! It carries everything, is extremely comfortable, light and does exactly what is required of it, can't ask for more than that.
I think that's it, for now! I am lusting after a Leica S kit but would need to sell both my houses to buy in to that! I find what I have to be superb for everything I shoot, any failures are down to me not my equipment.
Enjoy whatever you shoot with, it's all good fun!
