I always worked with Nikon with no problem. Then I decided to give Canon a try and bought recently a Canon 6D Mark II. Honestly, I'm SO disappointed. The camera doesn't focus well at all, I'm working with a Canon 50mm 1.8 lens and I simply loose lots of photos which never happened to me with Nikon. Purchased first one just before Thanksgiving and the second one at the beginning of February - both from Beach Camera. Good luck!!

I have been shooting on it for 2 years with no AF issues whatsoever. I brought the camera with me to Banff on a trip and it was accidentally dropped by my friend. I sent the camera to Canon and they cleaned and recalibrated the camera and lens ($500). Do you any other lenses that you can test out on your R6 Mark II whether native or adapted EF glass. Do you have other EF lenses that you could test out on your 6D Mark II.-Demetrius.

Mine was set to infinity when it should be set at the other setting. This might help 🙂. Recently upgraded to R6 and works great with my Canon 70-200 and Tamron 18-400 lenses. However, I recently purchased the Canon RF 800mm and I am Dual Pixel CMOS AF and a DIG!C 7 processer deliver Canon’s fastest & most advanced focus and subject tracking system for live view and movie shooting Shift time Create impressive 4K time-lapse movies in camera - the EOS 6D Mark II can also track auto exposure for each image taken during the time-lapse sequence "What the 6D Mark II is, though, is a solid, well-built camera that is capable of producing great images while improving upon its predecessor in almost every measurable way". The negativity centers around a decision Canon seems to have made that prioritizes resolution and liveview AF, over increasing the DR. 1aHf.
