The world changes when you use a macro lens on your digital SLR camera. You see things you never suspected were in the photo when you were setting it up. This is very cool when it happens.

For this discussion we will consider Canon EOS cameras with Sigma Macro lenses.

Why? Why not just get the Canon macro lens? Or why get a macro lens at all, can't you just use the kit lens?

These questions deserve answers.

First, about macro lenses. These are special lenses dedicated to close up photography. They are manufactured specifically for this purpose. However the pieces of glass are placed inside the lens barrel is just right for getting that macro photo.

A macro lens gets these close up photos with much better quality than any "normal" lens. Even the lenses that are multi-focal lengths and have the word "macro" in the name are not as good as a prime focal length macro lens.

Next, consider using a Sigma macro lens versus a Canon macro lens. Many Canon users would not think to go outside the Canon fold to buy any equipment. But there is at least one good reason to do this... cost.

Usually Sigma Macro lenses for Canon digital SLRs are less money than Canon macro lenses. 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.

Third party manufacturers like Sigma have made a commitment. They realize that if they don't get the quality right in their macro lenses, they will not get any of the market. So they did their homework and got it right. Their lenses are well engineered and produce great images.

There are four dedicated macro lenses if you decide on Sigma. The focal lengths are 50mm, 70mm, 105mm, and 150mm. Of these, the one that you should try first is the 105mm macro.

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 fill the bill.

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.

Sharp, fast, inexpensive

By Richard Aubin 

 Canon EF 50mm f/1.8 II Camera Lens

Once upon a time the 50 mm lens was THE standard camera lens and was THE optical benchmark by which manufacturers were judged and compared. Although the basic lens focus has now shifted (at least at the low to mid amateur level) to zooms - you can still benefit from years of research and development that went into designing the 50 mm lens and this here lens may be the best lens, dollar for dollar, that you can ever buy. The question is can you afford not to own this lens?

Years of development have brought us a lens that has a fast aperture of 1.8 - far faster than any consumer zoom lens - and that is sharp as a filed tack. Be forewarned about the sharpness . . . if you are taking pictures of people, this lens is unyielding in its sharpness and may well surprise you and your subjects whose every blemish is captured. The lens has a fabulously shallow depth of field if you want to use the 1.8 aperture to blow out a background. This lens is also ridiculously inexpensive. It is not USM - so it is a little loud. It does not have a moving focus scale. For the money though - this is heaven.

As to the build quality - yes, it is plastic. No, it's not built like the Rock of Gibraltar. If you are going to give this lens extensive use as your everyday lens and you shoot a lot, it may not hold up all that well as one reviewer suggests. However, I've now had this lens and used it fairly regularly (although not as the primary lens) for about 8 years and it is still in great condition. In my mind, spend the $$ on this first before you go and drop $330 on the 50mm 1.4 USM lens and I think you'll find it gets the job done nicely and that the extra $250 on the 1.4 may not be worth the difference in build (major difference), speed (minor difference) and image quality (minor difference).
