This is probably the most commonly asked question when discussing photography with someone. Before I answer the question I have to make one important point. The camera, lens and other hardware are just tools. They can not create good images by themselves anymore than the tools of a cabinet maker can create beautiful furniture without a craftsman who knows how to use them.
With that being said…on to the topic of equipment.
Photos on this blog were taken with a Fuji S2Pro, a Nikon D70, a Nikon D90,
a Nikon D7000, D7100 and D500. All are digital single lens reflex camera bodies with 1.5 crop sensors.
My most recent acquisition is the Tamron 150-600mm lens (x 1.5 crop factor = 225-900mm equivalent). I also use a Nikon 80-400mm VR lens (x 1.5 crop factor = 120-600mm equivalent). When I need a shorter focal length, I use the Nikon 18-200mm VR lens (x 1.5 crop factor = 27-300mm equivalent) or a Nikon 300mm (x 1.5 crop factor = 450mm equivalent).
For photography of small objects, insects, etc. I use a Nikon 105 mm micro lens. If I need a bit more reach I use a Kenko Teleplus Pro 300 DG 1.4x or 2.0x AF teleconverter.
I rarely use electronic flash but, when I must, I use a Nikon SB800 or Nikon SB80DX.
You don't need the latest, biggest, most expensive camera to take good photos. Here is a link to some excellent information about pixels, resolution, and good photographs: http://www.kenrockwell.com/tech/mpmyth.htm
I am always happy to discuss photography equipment and techniques so feel free to ask questions or leave comments.
