Yes Ken Rockwell Habibi :-)
Sample variation could easily account for any of the results in either of the tests. They are both fantastic top notch lenses, use whichever you own or best suits your project. Why does one necessarily have to win?

Would like to see the CP.2 f2.1 versions rated at wide open.
Very interesting and extremely helpful. Thanks!!!
Ultimately we make pictures and don't get paid the big bucks for shooting charts.
Mechanical performance is very important.

Interesting. The two video clips are good demonstrations. I am considering moving to stills lenses with the redmote pro so I find this a very relevant thread. I wonder though how much of this is amplified by the manual movement of the lens? Have all the people using the birger mount on the R1 been dealing with this problem for the last two years or does the wireless control make it less prevalent?
This has been a cool post to read, thanks to all.
Mark, I'm interested to know what exactly you mean by this.
Do you have any stills or videos you can show us exactly the smashing you are referring to?
EX: The images recorded looks sharper, the contrast is more pleasing to the eye, issues with lens sift on 40' screens? What exactly are we talking about here?
When the Birger/Impero system is working perfectly (mainly intermittent issues with the Impero) it is a really great system. It makes remote focusing extremely cost efficient and effective and enables an almost perfect amount of accuracy given the right L series lenses. It's amazing for me to pull off the lens by myself most of the time but then be able to have an AC take over and within about 15-30 seconds be able to grab the remote, fire it up, make some adjustments and pull focus off the big production monitor and never have to install any gears, set hard stops, or hook up power or any of the other things you need to do with a Preston type system. That's not to say that there's anything wrong with normal remote cinema systems, they're obviously awesome, but it was pretty amazing what was capable with the Birger/Impero system for the price and simplicity. I noticed very little image shift on any of the L lenses. For lenses that were not L series it was a whole different ball game. Lots of image shift, very jerky focus and other issues.
SALT I and SALT II, very informative and empowering, thanks.

THANK YOU EVIN, and all those involved in the testing.
Great work!
