I guess there is hope still.  :)  I'll give manual mode a shot when I purchase my next lens.  Shouldn't be long now....

I tried manual mode today on my 50 f/1.2 on my 5D Mark III and it worked beautifully.  It's my toughest lens to calibrate and while I wouldn't use manual mode for my 5D Mark II, considering I have to sit there and fool with my 5D Mark III, it was much more efficient.  It took my about 2-3 minutes total to take the shots (2 at each multiple of 5 from -20 to +20) because I didn't have to sit there while it downloaded...and processed...and calculated...

You have to manually enter the AFMA setting, but if you do -20, -20, -15, -15...15, 15, 20, 20 like I did, it's not hard.  It still takes a while to process the RAW files, but overall it's a much more pleasurable experience and all but one of my shots was consistent and I got great results.  No "adding more shots" crap that I get with it tethered, particularly with this lens.
Definitely give it a try, especially if you're a 5DIII or 1DX user, and most especially if you're using fast glass.  f/2.8 and slower lenses have never given me any problems, but my 135/2, 85/1.2, 50/1.2, and 24/1.4 have been a challenge, if they've even worked the first 2 or 3 tries.

Interesting.. I will try manual with my 50 L and see, since it's already adjusted, it will be obvious if I failed or not.. Thanks!

I'm thinking of getting the FoCal Pro. I know that you need a tripod and plenty of light. Would it be OK to perform these tests I guess you would call them outside on a driveway on a sunny day?

Probably okay on a CALM, sunny day with no traffic.  You don't want any movement/vibration of either the camera or the target.  If walking across the floor can affect the results, so can wind or a heavy truck going down the street.

Biggest problem I had outside was the occasional cloud really messing with the light level. But no wind and no clouds should be fine. Just be aware of that 10 ev is quite a bit of light and way too much light can also mess up the test.

I did searches for Reikan FoCal @ Adorama, B&H, and Amazon... nothing.  Where is the link for the thing?
