Full Frame

Canon 6D Mark II

     This is the entry-level version from Canon.  Features a much improved focusing system over the original and has also added a swiveling screen.

     The image quality is no different than what the more expensive models offer.  

     I'm a big fan of simple and high quality and this would be it.

Canon 16-35 4.0 IS

     I normally favor prime lenses for their arguably better image quality, but the versatility of this ultra-wide-angle is a very acceptable compromise (with more than adequate image quality nonetheless).

     f/4 is probably as low as you'll ever need to go in this range and image stabilization can be nice unless on a tripod.

Sigma 50 1.4 Art

     50mm, on full-frame, is a little wider than what the eye sees.

     I agonized a lot over which 50mm lens to get and this is the one.  It's really a very special lens that has it all - sharpness, "that special look" and lives on my camera unless I have a wide-angle or telephoto need.  Love it; a lot.

Canon 135 2.0

     A good way to achieve "that special look"; with the distance allowed by this focal length creating a very natural/non-distorted result.  Universally recognized as among the best.

     IS isn't really needed in most cases as long as you keep your shutter speed around 1/160 or faster.

Canon 300mm 4.0 IS

   It's a tough call between this and the 400mm 5.6, but this lens will be more useful overall.  Very similar to the 200mm f/2.8 on a crop sensor with the added bonus of IS.

   IS won't matter with faster shutter speeds, but may when slower than 1/320. When image quality is your #1 priority.

Canon 100-400 II

     This lens is overwhelming versatile and offers remarkable image quality.

     f/4.5 at 100mm isn't great, but since the DOF decreases with an increase in focal length f/5.6 is pretty good at 400mm.

     I generally like my prime lenses, but can't get past the usefulness of this lens.  

My personal choice.
