dopravopat's current gear

Canon EOS 30D
Canon EOS 60D
Canon EF-S 18-135mm F3.5-5.6 IS
Had it converted to IR in 2014, using is more since then.
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.
Sigma 18-35mm F1.8 DC HSM Art
Sigma 50-100mm F1.8 DC HSM Art
Sigma 8-16mm F4.5-5.6 DC HSM
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.
Tripod collar cannot be removed and gets it the way when rotating the zoom ring.
Other gear:
  • Sigma 18-50mm F2.8 EX DC The old, non macro version, 67 mm filter thread, keep it as a backup
  • Sigma 50-150mm F2.8 EX DC HSM The old Mk I version with front focusing issue at 150 mm
  • Sigma EF-530 DG Super Flash
  • Sigma EF-610 DG Super Flash
