For anyone who has seen this and still is not happy with the result, I've discovered that when using an all in one lens for cinemascope format (anamorphic built on to the lens and not attached) you have better sharpness and focus rather than using the two lens option. The major problem is with countries which get prints with Laser Subtitling. If you want a better picture, get an all in one lens for cinemascope and it will surely give you a sharper focus all around the image instead of a compromise. My 2 cents of advice.

Becuase the surface is embosed to laser subtitle it is in a different plane than the rest of the image so focusing is an issue
A lens of a slower f stop will have a better depth of field and maybe hold it in focus better at the cost of light

I agree with Gordon. Laser or wax-etched subtitles are at a slightly different focus point than the picture image. It is most noticeable with shorter focal length lenses, or lenses that are very "fast" (small f/number). If you have enough light, a lens stop can really help increase depth of focus.

I've found that the audience will complain a lot more about soft focus on subtitles than they do about slightly soft focus on the picture, it's just easier to see soft edges on large print.

Bill is very right.
I always have difficulty focusing laser subtitles than waxed ones. what I do is a compromise to the point the lettering becomes slightly softer.

Focus depanding from the light concentration. Hight concentration give blur and depanding from the projector position to the screen.
