Read user's review Had it converted to IR in 2014, using is more since then.	Read user's review Seems to have one dead pixel on sensor, but ACR handles it without problems.	Use it only for IR as it has no "hot-spot" issue or it is barely visible. Got it with another EOS 60D that my father now has. AF is slow and inaccurate, overall wobbly construction compared to my high-end Sigma lenses. Only the old first generation Sigma 18-50mm F2.8 EX DC is equally bad in AF and mechanical construction.

	Survived two drops from about 1 meter on asphalt concrete. Still working without problems.	Optically excellent. AF inconsistent and even with the USB Dock impossible to calibrate, this costs one star in the rating. I would need way more calibration points than the 16 provided by Sigma, 55 would be a good starting point. Once calibrated, the lens focuses consistently - but only on the calibrated spots.
Sigma 50-100mm F1.8 DC HSM Art	Sigma 50-150mm F2.8 EX DC APO OS HSM	Sigma 50mm F1.4 EX DG HSM
Read user's review Tripod collar cannot be removed and gets it the way when rotating the zoom ring.	Too big and heavy compared to the older model. But that is the only bad thing to write about.
