Sigma 50mm f/2.8 AF Macro

My Perfect Lens I originally bought a Sigma EX DC 18-50mm lens for Canon back in '07 to use with my Canon EOS 350D Rebel XT. The images were amazingly sharp, both macros and distance shots came out beautifully. I sold my camera and lens in 2013 and started using a Sigma 10-20mm with a Canon T2i but missed the flexibility of the Sigma 18-50mm. Having purchased another Sigma 18-50mm lens has made a world of difference. I recently visited a local zoo and was able to take clear detailed images from quite a distance, something I wasn't able to do with the 10-20mm. I've also been photographing white gulls at the local reservoir and have captured extraordinary stop-motion close-ups with the 18-50mm lens. I'll never part with this lens again.

Good I'm very happy to make deals with you, the lens it's what I saw. Thanks I recommended you

Sigma SA 50mm f/2.8 EX Macro This is a phenomenal lens for Scenics ,flower and insect photography. Its sharpness and clarity are reminiscent of the Zeiss Planar Makros ,yet incorporating all the newer technologies that Zeiss and Leitz lenses lack, such as autofocus and ,particularly relevant for insect photography, Auto Exposure , the one difficult part of Macro Photography. This lens has an extended focus range ,controlled by a switch in the barrel, that allows it to reach Life Size reproduction ratios (1:1),right out of the box, without the need for bellows ,extension tubes or closeup lenses. It can also be utilized on manual focus mode if so desired. The EX Series, known as the professional Sigma series,is a Full Frame lens that when coupled to a Digital Sigma camera will only utilize the center of the image field where the lens aberrations are corrected , as opposed to the DC model that will not cover a full 35 frame and will by force use the lens to its edges ,where residual aberrations always remain. To top it all ,this is an f2.8 lens ,that is very luminous and suited to natural light photography,from Dawn to Dusk.
