I use fairly ordinary cameras and most of the recent street photographs were taken with a compact camera the Panasonic Lumix LX3 which has a lovely little Leica f2, 24 -60 mm zoom lens, which I have used since June 2010. I often use the generic Dynamic Black & White mode - in camera - so I can view the scene in B&W before I take the shot.
Quite a few images were also captured on my first Digital Cameras - the Nikon Coolpix P5100 and the E5700. I also used a DSLR Nikon D80 / D300. I no longer use these.
My current *DSLR Camera is a Nikon D600 which I use with Nikon 85mm f1.8 D lens; Sigma 50mm f1.4 Art lens; Sigma 35mm f1.4 Art lens; Nikon 24-120mm f4; Tamron 70-200mm f2.8 .
All the shots taken with the D80 / D300 / D600 cameras were originated in colour mostly in RAW. Some later converted into Black & White using image editing software on my laptop.
Since 2012 I'm also using the Fuji X100 / X100s which has a fixed 23mm f2 lens (equivalent to 35mm in full-frame terms) and is a great little camera for Street & Low Light Trad Photographs. I have also added Fuji X-Pro 1; X-T1 with 27mm f2.8 Lens; 18mm f2 lens; 18-55mm f2.8-f4 lens
Most of my early film work, was taken on a variety of 35mm cameras - mostly those such as the Canon A1; Canon A-E1; Canon T90 and other smaller Range-finder style 35mm Cameras. All used Manual Focus Canon Lenses, ranging from 24mm to 300mm.
Some earlier Studio and Landscape work I used a Kowa Super 66 (aka 6cmx6cm square) with standard and portrait lenses.
The 1980s trad photos on this site were taken on film - mostly 35mm and shot in Black & White using Ilford FP4 & HP5 Film and Kodak Tri-X. Conventional chemical development.
* DSLR means a Digital Single Lens Reflex camera.
