Sigma Reviews

This 105mm Sigma macro lens with a fast f/2.8 aperture satisfies you in every department. First of all it gives you a 1:1 true life size macro and these macro images comes out truly amazing... extremely sharp, good color saturation and contrast(on Pentax ZX-7). The 105mm focal length is also suitable for taking portraits. Portrait results have also come out extremely well. The EX finish is aesthetically pleasing, scratch proof and has a metal alloy body for sturdiness. The hood which is provided along with the lens matches well with it. One can also use a 77mm dia lens cap which fits perfectly on the hood, so that the hood can remain permanently on the lens (hood is threaded so that it can screw on the lens like filters.)

A bit of a bother is the clutch mechanism which on has to engage/disengage while changing between MF/AF. But on the positive side, the focus ring doesn't move (in AF mode) and one is more at ease while holding the camera. The other thing is the long rotational travel of the focusing ring while focusing a subject and in AF mode this could sometimes take a while. This could be somewhat solved by using the focusing limiter switch.

Definitely, a well made lens optically and structurally and should satisfy one and all.

I bought this lens when they had a sale. It was [price] without shipping charge, and I think the price was the lowest anywhere.
I love this lens. It is a lot sharper than EF 28-135mm IS, which I use most of the time. Now I can take good pictures of teeth from my patients and also good portraits for my baby.
Overall it is very versatile and overall quality is excellent, and I would recommend to anyone interested in macro photography.

Sigma 105 EX macro is considered one of the best primes for its optical quality. MTF tests, which determine how sharp the lens is, place it just below the famous Canon 100mm Macro. The EX sign tells that the build quality of the lens is higher than that of a consumer-grade product. The big plus is a price. It is almost twice cheaper than Canon 100mm. ALso, it comes with the case and a hood and Canon does not. The drawbacks, however, include potential incompatibility with the future Canon camera bodies. I would highly recommend this lens for advanced amatures on a tight budget.
