Problem with two different Canon 85mm f/1.8 Lenses

[shawnhopkins]

A while back I was having intermittent problems just on a Canon 85mm f/1.8 USM lens. All my other lenses work fine. Sporadically I would get, "Communications between the camera and lens is faulty. Clean the contacts". It seemed humidity played a part but I could never consistently reproduce the problem. I wound up buying a second 85mm brand new. Now, as of today, this lens is having the same problem, but all the time. My F-stop is 00 so I know there's something not right. The contacts look clean. Like I said it's only on these 85mm lenses. I did try using a soft cloth to wipe the contacts, nothing abrasive, but no luck. Any thoughts are appreciated.

That is the start of a pretty decent FF camera kit.  I own the same gear.  Those two lenses are true gems for their costs.  I would recommend saving up a little more and buying a constant f/4 aperture, zoom “L” lens next.  

I recommend going wider or longer.  You can do either for under $1000.  You could get either an EF 17-40mm f/4L IS USM zoom,  which is currently selling for $300 off.  Or, you could get the EF 70-200mm f/4L USM zoom, which is also on sale this weekend.  Another choice is the EF 24-105mm f/4L IS II USM.

Or, save up even more for one of the f/2.8 constant aperture zooms in the same ranges.  I think one of the most versatile lenses I own is the EF 70-200mm f/2.8L IS II USM zoom lens, which has been recently superseded by a Mark III model.

I believe that the above photo was shot at 100mm f/5.6, using the 70-200mm lens.  The camera body was a 6D Mark II.  I used Continuous Drive mode, and AI Servo with all AF points active.

Canon’s L lenses will take your photography to a whole new level, most especially if you can get your hands on one of the f/2.8 zooms or primes.
