.."the Supertelephoto primes (300 f2.8, 400 f2.8, 500f4, 600 f4 from both Canon and Nikon) are our lowest repair rate lenses. Basically we’ve only had damage repairs for any of them.
A couple of observations.
The Sigma 120-400 and 150-500 are no longer on the list because we no longer carry them. Both had failure rates of about 45% while we had them. New batches may be better (ours were all bought early), we don’t know.
The failure rate for the Sigma 120-300 is still high, but much better than it used to be. We think this is because we’ve changed the way we pack this particular lens. We no longer see the very high failure rate after shipping that we once did.
The Canon 300 f4 IS has leaped up this list. It was a lens we’ve never had trouble with in the past. It may be notable that we turned over a large number of copies (6) about the same time last winter and these seem to be the ones having trouble, despite being newer lenses. I have no certain knowledge, but wonder since the problems seem largely electronic, if there was a batch of bad circuit boards or connectors.
The Tokina 12-24 f4 PRO also climbed up the list only recently. It may be significant that a number of our copies are now 18 months old, particularly since most of the failures seem to involve zoom mechanism mechanicals.
The Canon 35 f1.4 is probably a bit of an outlier: when we started using a more sensitive tool (Lens Align Pro) for calibration checks we immediately found several copies that needed calibration which raised its repair rate significantly.
Two lenses: The Canon 50mm f1.2 and the Sigma 100-300 have behaved so well they’ve dropped below the 10% repair rate cutoff.
