No, you are not really missing anything. Since most of his viewing is 16:9, most of the time he can leave the lens out of the light path. Cgott42 says he will watch Scope films maybe two or three...

I thought I would take this opportunity to post a couple of jpegs, one that shows the difference in how Vertical Compression (VC) lenses work vs. their Horizontal Expansion (HE) counterparts, and the...

Just to make sure everything will work properly -

You said you had an 18' throw. Is that correct? For the FVX200 you should be at about 4.3X the screen height. You said the screen is 51" tall,...

Hard to argue with this, and would agree 100% if we were talking typical list prices :) When the lenses in question are $200 - $500 it makes it a slightly harder call.

IMO.

No. See my just posted reply to Stanger89. When you zoom with the FVX200, you get the brightness benefits of zoom AND lens.

With either design - VC or HE - you get to use the whole 1920 x 1080...

Yes, at the same image size. First of all, as you pointed out, opening the lens aperture to zoom also increases light output, and of course you need to zoom with a VC lens. Of course, the...

Vertical compression designs result in brighter, crisper images than horizontal expansion by their nature. Shoot out an FVX200 with any horizontal compression lens sometime :)

Personally, I would save the $200 and just zoom. AR just means "Anti-Refective." You will still have chromatic aberration and astigmatism issues with the HTB, which you won't have if you zoom. Why...

Any of the Panamorph lenses except for the FVX200 will work with your setup.

If you are determined to crop the 235:1 image, the Lumagen or DVDO option makes the most sense. You get all the brightness with the least compromises. Of course, you are destroying the artistic...
