Canon EF 35mm f/1.4L II USM Lens Compared to Version I
The Canon EF 35mm f/1.4L II USM Lens Review page is loaded with my expectations for this lens along with comparison charts and other information.
 
Canon's MTF chart foretells exceptional optical performance. An MTF comparison between the version I and II lenses is included in the preview.
 
The image accompanying this post shows an approximate size comparison between the older Canon EF 35mm f/1.4L USM Lens (on the right) and the new 35 L II. Obviously, the new lens is modestly larger.

Canon EF 100-400mm L IS II Lens
MTF charts have been added to the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens Review.
 
The 100-400 L II is, in many ways, an impressive zoom lens. The MTF charts (especially the variance charts) highlight its optical impressiveness.

Canon EOS Rebel T6i
The definition of "perfect" in regards to T6i/T6s (750D/760D) setup is of course referring to my own preferences. That there are so many setup options shows that not everyone is the same as me.
 
  1. Open the box, find the battery and battery charger, connect the two and plug the charger in. A charged battery is needed for almost everything going forward.
  2. While the battery is charging, the one step that can be accomplished is software installation. Canon Digital Photo Pro and EOS Utility are the two apps I load.
  3. Another step that can be taken parallel to battery charging is installation of the neck strap.
  4. Install the charged battery and power on the camera. Update the date, time and timezone as prompted.
  5. To enable the full set of menu options, turn mode dial to P, Tv, Av or M. Then begin changes by pressing the Menu button.
  6. Change "Image quality" to "RAW"
  7. "Beep" to "Disable"
  8. "Release shutter without card" to "Disable" (Important)
  9. "Image review" to "4 sec."
  10. Set all "Lens aberration correction" options to "Disable"
  11. "Picture Style" to "Neutral" with "Sharpness" set to "1". Note that I select the Neutral Picture Style for a lower contrast histogram to better show the camera's available dynamic range in-camera. I usually change image to use the "Standard" style in DPP during post processing.
  12. "Long exposure noise reduction" to "Auto". I frequently change this option when shooting, most often to "On".
  13. "High ISO speed NR" to "Off". Noise reduction reduces image sharpness and very potentially destructive to image details. I apply NR to my taste (usually very lightly) during post processing.
  14. Live View "Grid display" to "Grid 1" to get the thirds lines
  15. Histogram disp from "Brightnes" to "RGB"
  16. "Auto rotate" to "On/Computer". This allows images to fill the camera LCD regardless of the orientation they were captured in.
  17. Viewfinder display: Set Electronic level, Grid display and Flicker detection to "Show"
  18. "Feature Guide" to "Disable"
  19. Custom functions: ISO expansion: On,
  20. Setup My Menu to include: Long exp. noise reduction, Anti-flicker shoot, Format card, Date/Time/Zone, Mirror Lockup, Sensor cleaning
Regardless of your setting alignment with mine, I recommend that you maintain your own camera settings list. The list will be helpful if your camera requires reconfiguration (such as after returning from Canon service) or as a basis for configuring your next camera upgrade.

3D Isometric MTF Chart
The new MTF Comparison Tool has just received 4 additional chart types. Joining the Average and Variance charts are the 2D Map and 3D Isometric charts in 10 lp/mm and 30 lp/mm formats.
 
Among the additional lenses loaded into the tool are the 24-70mm f/2.8 zooms (Canon, Nikon and Sigma). Remember that CA is generally more prevalent in zoom lenses (especially in the maximum focal length extents) and that CA is a significant factor in corner MTF performance (and is generally an easy-to-correct aberration). If you see chart lines/colors showing decreasing MTF measurements toward the corners (right side or periphery), CA may be at least some of the cause. Reference the Lens Image Quality Tool to see if CA is a significant component of a dropping MTF chart measurement for a specific lens.
 
One of the zoom lens additions is the new Sigma 24-35mm f/2 DG HSM Art Lens. Of note is that, while the tool says "Average" for the chart type, only one copy of this lens was available for MTF testing. The test results will be updated (and the other chart types added) when a larger sample size is available. B&H has the Sigma 24-35mm f/2 DG HSM Art Lens in stock.
 
There are enough results in the MTF tool to entertain for hours. Here is a comparison that I find interesting. While these are not equivalent apertures (one stop apart), B&H has the Zeiss 135mm f/2 Lens in stock with a $300 instant rebate bringing the price down to far less than half that of an Otus.
 
Be sure to share the MTF tool with your friends!
