Sigma EX Macro lens-180mm-F/3.5-Canon EF

The Sigma EX Macro lens-180mm-F/3.5-Canon EF lens is a high performance telemacro lens that can focus from infinity to full 1:1 lifesize reproduction without accessories.

Sigma EX Macro lens-180mm-F/3.5-Canon EF Overview

Convenient for photographing subjects, which are not easily approached, the 180mm f/3.5 Macro features apochromatic design, two SLD (Special Low Dispersion) glass elements, and a floating inner focus (FIF) system. A focus limiter switch aids in faster AF by restricting the movement of the focusing mechanism to a smaller portion of its enormous range. Usable with Sigma's 1.4X EX teleconverter as a 252mm f/4.9 lens providing AF function from infinity to about 47" or with the 2X EX teleconverter as a 360mm f/7 lens in manual focus.

This lens is designed as a high-quality macro lens, good for film or digital SLR cameras. The improved DG lens design corrects for various aberrations. This macro lens is specially coated to get the best color balance whilst cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration, which is a serious problem for digital SLR cameras.

Sigma EX Macro lens-180mm-F/3.5-Canon EF user reviews

"Has a good build quality the the images are not as sharp as other macro lenses I have used. Really needs to be stopped down quite a bit. The auto focus tends to hunt quite a bit. "

"I've only had this lens for a few days, but I am happy with it so far. Could even capture two ants attached to the wing of a butterfly. Getting close, as in the 18" minimum distance, works as described. Auto-focus does hunt a little when close to object, had to manual focus. Great lens for the money."

"A wonderful lens at an unbelievably wide end of the zoom range. Sharp and compact. Hold it and fall in love.REALLY WIDE AND REALLY SHARP but wide open is only f/4 at bestPros:Snappy, contrasty, well made, well designed.Cons:Slow at maximum aperture."

""Since I have had this lens it has been on my Pentax K20D all the time and has seen a lot of use photographing flowers and insect life as well as some portraits and a couple of landscape shots.

I have found it to be extremely sharp and give a beautiful blurred backgroung to macro shots and portraits.

Mounted on a solid tripod with a remote release or mirror lock up the results are amazing.

I have nothing but praise for this lens" "
