I have a chance to get a 1.5-1 Bell & Howell ANAMORPHIC Lens. if I were to mount it in front of my Sony VPL-HS 60 projector, do you think it would give me an image close enough image to 2.35:1? Or would I have to get a scaler and different lens?

Probably not, but not for the reason you are thinking. You would need a 2.66:1 screen, but the real issue is that the lens is physically too small to handle the beam coming out of a video projector.

The lens has a 2 inch rear aperture. I turned on my projector and placed a piece of paper a couple of inches in fron of my lens and I measured the image projected on the paper was close to 2 inches if not slightly smaller.


Since this semms to work, will I need any scaling. My projector is native 16:9.

You will need very specific scaling but it also seems too small for the image. You need alot of room around the image projected to adjust the lens of you will get blurry corners.

So you think the 2 inch rear aperture is going to be too small for my projectors output image onto the lens?


If you can look at this. This is the lens in question and tell me what you think?

No it won't work. The rear aperture is far from the only consideration here. The beam will expand and the front element will be too small. Also, I have 3 of them and there is no way that it has a 2" rear element.

I didn't think about that. Your right. What is that lens good for? A camera?


Anyways if I go with a HTB-AR Anamorphic Lens. Will I still need a scaler too?

 

[Vern Dias]

It was used for 16mm scope projection. If your projector doesn't do a vertical stretch, you will need a scaler... or an HTPC.

Vern,


Just to clarify, with your 1.5x lens, you have to apply both VS as well a portion of HS to get the geometry correct?

No, more like verical stretch and horizontal shrink, although I never think of it in those terms. It's just a slightly different flavor of scaling as done by YXY / Theatertek / Crystalio II scaler.

Thanks Vern

VS = Vertcial Stretch

HS = Horizontal Squeeze


I am intrigued by the extended flexibility and seriously considering adding a scaler one day soon...
