I seach about What the diffrent are on zenmuse X5, X5R and X5S?

Begin your study here -> Click here to review a comparison of Zenmuse Camera/Gimbals

P.S. -> The first generation Inspire 1 (X3, X5, X5R) cameras and the second generation Inspire 2 (X4S, X5S) cameras are different generation devices with totally different processing archetectures. Therefore the X3, X5, and X5R are only compatible with the Inspire 1 and OSMO (X5 & X5R), while the X4S and X5S can only be used on the Inspire 2.

The biggest diffenced i can se its CMOS size and on X5S vs X4S is i can change the lens?

The X4S is a fixed lens. Only the X5S can have interchangeable lenses.

Good comparison between the X5S and X4S here - lots of specs to compare.

If you wanted to investigate X5 vs X5R then this is a good resource too.

No problem, best of luck to you.

You definitely should only get the 2nd generation of camera as the loss frame issue has been implemented there only.
