Close Up Photography – Equipment & Technique
Macro photography has turned out to be a hobby (or profession) for quite a few photographers in the past handful of years due to better quality equipment for sale at reasonable prices. This write-up was originally published on my Nature and Travel Photography web site and shares my thoughts with regards to what to buy if you are interested in shooting macro photos. I recommend the The 123di Suite for additional information, a FREE sample is available.
Macro Photography Equipment
* dedicated macro lenses
* extension tubes or bellows units
* reversing rings
* close up lenses and
* macro zooms (which are pushing the limit of what we are talking about)
Dedicated macro lenses are the best way to go if you are serious at all about doing this type of work. It doesn’t have to end up being pricey, I purchased a excellent 50mm Sigma Macro lens used for all of $120 (brand-new about $270) and it really is tack sharp and produces amazing images. My main macro lens is a Sigma 150mm Macro and cost a huge $700, the best money I have ever spent. This gives you an idea about the price range available and the sky’s the limit with several highly specialized Nikon macro lenses in the $1,600 range. Why the variation in focal lengths? I’ll get to that soon in another article that I’m working on! If you are really serious about macro photography purchasing a lens specifically designed for the purpose is the best way to go. The lens models are optimized for close focusing and the lenses are also generally flat field (focus in a flat plane) producing crisper corners on flat objects such as pieces of wood or slabs of rock. Flat field may be a term that many have not heard of and I’ll elaborate later on this as well.
Extension tubes or bellows units are pieces of equipment that put space between the camera body and the lens thus allowing the lens to focus closer. They can work well with certain lenses, for instance, if you have a 50mm prime lens this may well be a great option to get into macro work at an affordable cost. Extension tubes often come in sets of 3 of various lengths (high quality tubes tend to be sold individually) that can be employed singly or combined to get the close focusing distance required. Bellows units work on the identical principle but are expandable like a “bellows” allowing a good deal of flexibility. The real drawback is the expenditure and they are bulky and heavy as well. I expect most individuals use bellows units for studio work only as they aren’t terribly practical in the field. One area where extension tubes really stand out is definitely for making lengthy focal length camera lenses such as a 300mm focus closer, great for photographing skittish damsel flys and other critters.
Close up lenses are clear “filters” that screw onto the front of your lens making it possible for the lens to focus closer. Level of quality varies from mediocre to quite acceptable dependent on the quality of the filters. This is likely the least expensive way to start shooting macro but does have its drawbacks. A large factor that has to be looked at is the quality of the camera lens you will be using. Inexpensive zoom lenses will probably produce less than stellar results while high quality prime lenses can produce excellent results but none of these will produce tack sharp results like the dedicated macro lenses. The biggest advantage? As these are just fancy filters they are very light, no extra tubes or additional lenses to carry.
You don’t hear much about reversing rings anymore and I expect that’s because most people are using zoom lenses that likely wouldn’t work very well. Reversing rings allow you to install a lens “backwards” on your digital camera body. When used with high quality primary lenses the outcome can be amazing and if you invert a wide angle lens generally an individual can easily achieve a large magnifications on the order of 2 times or more. For people interested in large magnification shooting this is often the way to go, especially if you’re on a budget.
What about the macro zoom lens that you presently have possession of? Several of the new lenses that come as acomponent of a kit are branded as macro zooms and while they do focus a bit closer than normal they’re definitely not true macro lenses. My personal experience has been that most of them are extremely suspect in terms associated with sharpness as these types of lenses are not developed for this sort of application. Of course in a pinch they will function but to get in really in close proximity to your subject one of the above options would be best.
What are you presently using? Are you satisfied with the results?
