I unashamedly enjoy trying out new cameras and lenses as much as many other photographers. However equipment is merely the means of capturing the photographers vision; akin to the artists canvas. The question "what equipment do you use" is best answered: "my eyes, my feelings, and my inspiration".
Therefore I will not list my camera equipment here, although I will say that I no longer have a DSLR. Coupled with good quality lenses, the latest APSC and full frame EVF and rangefinder cameras are capable of such excellent performance I cannot see a reason to carry heavy DSLR equipment around.
It is certainly my experience that different equipment can shape the type of image I make. I keep a range of camera equipment, and find that the camera I use is determined not only by technical issues but by what I am trying to communicate, or simply how I feel that day!
I also use a mobile phone and small compact camera. Using small cameras/mobiles without a tripod is a liberating experience; encouraging experimentation and instinctive, reactive and free-flowing photography. This is an invaluable way to learn and to practice 'seeing' and visual-communication skills, and there is no excuse not to practice daily as a mobile is with me most of the time!
One reason (excuse!) to get more equipment is advances in technology. Again, they won't improve your photography, but they do make life easier!
Recent features that have impressed me are:
Focus Peaking - great way to confirm depth of field, but take care. They work on contrast and can mislead where there are high contrast edges in the picture.
Zebras (Sony) - this is a simply amazing feature .... no need to check histograms after taking the picture! The zebras show you areas of potential overexposure before you press the shutter, and are much more useful than a live histogram because the zebras show where in the image the highlights could blow, and without a histogram obstructing the live view image.
And, some software I have recently started using:
Luminosity Masking - an incredibly powerful and simple way to improve tonal separation, zone by zone, when editing in Photoshop. I have found Tony Kuyper's Luminosity Mask Panel to be most impressive.
