Sigma Macro For Canon Eos Cameras - Sigma Lenses Fit Canon Dslr
Something mysterious happens when you use a macro lens to your Canon digital SLR camera
. You witness things you never imagined were in the photo when you were setting it up.
This is very cool when it happens.
This article is about Canon EOS cameras using a Sigma macro lens, but if you are a Nikon or Pentax user, the same lenses are available to you.
What's the big deal about Sigma? Wouldn't it just be better to get a Canon macro lens? Another question, can't you just use any lens for macro photography?
Good questions, indeed, and they have some very definitive answers.
First, about macro lenses. A specially designed lens is used for getting really close to your subject. It is a macro lens. They are manufactured specifically for this purpose. Lens elements in a macro lens have a different configuration, or set up, than a regular lens.
This allows the macro lens to take much sharper and clearer photos when placed close to a subject. You may have seen, or even own, a zoom lens that has the word "macro" in its title. This type of lens is not as good as a single, or prime, focal length lens that is designed for macro photography.
Next, consider using a Sigma macro lens versus a Canon macro lens. Lots of Canon photographers consider this digital photographic heresy. If you are one of these, you may as well move on. However, there may be a valid reason to think about it... cost.
Almost always you will pay less for
Sigma macro lenses for Canon digital SLRs than you would pay for a Canon macro lens. Photo quality is really good with either choice. You may not be able to tell the difference between photos taken with one or the other, in fact, you probably can't tell the difference. It would take a forensic scientist to tell which is which.
Sigma, being a third party manufacturer of lenses for Canon EOS cameras, has made a commitment to excellence. They understand that if they don't get the quality right in their macro lenses, they will not get any of the market. They put lots of time and research into getting it right. What they ended up with are great engineering and great lenses.
There are four dedicated macro lenses if you decide on Sigma. The focal lengths are 50mm, 70mm, 105mm, and 150mm. If you do not have a really good reason to get one of the others, the 105mm is the right choice for your first macro lens.
The others are good, but the 105 is the highest rated for two reasons. You get a 1:1 ratio, which is the true test of macro, and it can double as a portrait lens. Many portrait photographers use a 100mm lens for the lion's share of their work, and this one will do the job.
If you check the user ratings (which is highly recommended) you will find that the Sigma 105 macro lens for Canon is right up their with the home-grown model.
Close up photography is really rewarding. The beauty and intricacies of nature make you realize that there is a Creator, and He did not hold back, even in the most minute details.
