Thanks for the feedback. I'm having a tough time figuring it out. I'm using Dottune to try and calibrate it and I get anywhere from -4 to -17. I was calibrating using different distances but only measured using live view in Magic Lantern. I think I need to do it again but measure my distances out. Then I'm not too sure if I should calibrate at 25x or 50x the focal length. Ugh. It was so much easier with film. We didn't worry about it anywhere near as much.
Here's a closer crop of just the eyes. The do look reasonably sharp to me. What do you think?
that is better and why i mentioned uploading - unless you can see the actual file size, sometimes uploading a certain size file can create a blur that isn't really there
i've always used 50x
the biggest bad thing i found you can do is to test in indoors under tungsten light and then go outside and shoot in bright shade or test again under this scenario
so in other words, knowing you Dot Tune adjustments based on the type of light you are using can be helpful - or better, don't set your adjustment using a more extreme wavelength and expect it to be perfect at the other end of the colour spectrum
kiss - DOT tune to 'daylight' is generally a good idea
the other thing i know is that when you are shooting people with dark brown eyes, you can get the appearance of them not being sharp because you often can't get depth of light inside the eye - so in certain situations they can look not sharp and it isn't true (but it also is because there isn't DoF inside the eye if you get what i'm getting at
Hockey and wedding photographer. Favourite camera / lens combos: a 1DX II with a Tamron 45 1.8 VC, an A7Rii with a Canon 24-70F2.8L II, and a 5DSR with a Tamron 85 1.8 VC. Every lens I own I strongly recommend [Canon (35Lii, 100L Macro, 24-70F2.8ii, 70-200F2.8ii, 100-400Lii), Tamron (45 1.8, 85 1.8), Sigma 24-105]. If there are better lenses out there let me know because I haven't found them.
