Hello everybody,
I am very new in photography. I have Nikon D7000 with two kit lens (18-140mm and 55-300mm). I am interested in Macro, Landscape, Wildlife. I need your advice to buy a macro lens which is compatible with my DX Nikon body. Do I need to buy any other things for macro photograpgy like ring flash, tripod? Thanks again.
Macro is not the same as closeup. But are related. For macro photography the best lenses are those that are optimized for working at or near the minimum focusing distance, and have a long "ramp" (more than 360 degrees to turn the lens from infinity to minimum focus distance) on the focus ring for precise focusing. Most of the true macros have this, and luckily most of them also provide really good image quality. You can go with Nikon of course, but lenses from Sigma, Tamron and other mfgrs.
With a cropped sensor camera, you will have the benefit of greater working distances. So a 90mm lens will give you the same field of view as a 135mm lens on a full frame camera, but your minimum working distance won't be affected. This means for the same field of view, you can be further away than if you put the same lens on a full frame. Typical focal lengths for macro for field use (not in studio and copy work) are 90mm to 180mm. I use a 150mm and a 180mm with a full frame body. But I did use these with a D300S with great results, and they will work fine with your D7000.
There are all sorts of lighting solutions, tripods, Wimberley makes "Plamps" to gently hold plant stems to keep them steady in the wind, a tripod is a great idea if you are really close, and a decent (not the $40 cheap stuff coming from China that you can buy on eBay), set of macro focusing rails to precisely compose your images. They also help when you start doing focus stacking - a pretty standard technique for really close macros that require greater depth of field than a lens can typically provide.
I tend to like directional light on natural subjects, which makes ringlights out of the question. Directional light provides contrast and shadows, which help define texture and depth.
You "can" use extension tubes, but your results with a standard, non-macro-optimized lens using tubes may not be good enough. Extension tubes do work very well with true macro lenses, however. So if you buy them as an entry level to macro, your money won't be wasted.
