Re: Making A DIY Anamorphic Lens

Well firstly..welcome to the Shack mnfish..

Ideally the prisms for a DIY lens need to be 5" x7"..This size will be suitable for most projectors..

Most commercial lenses these days are using 4 prisms plus corrective elements..
These types of lens units are beyond a DIY set up..but the 2 prism lenses do a fine job and well worth the effort..

Re: Making A DIY Anamorphic Lens

Thanx for the Hello!!

The reason I ask about the number prisms is that 4 of them seem to do away with the rainbow affect on the outer edge of the screen? Or would it be better to have a curved screen? Is that just too much to get into for a simple home theater screen? And looking at cost of the prisms...they aren't that cheap? The ones I was looking at were $66 US each.

Re: Making A DIY Anamorphic Lens

A curved screen won't have effect on any Chromatic Aberrations that you see at the sides of a screen.
Curving the screen helps to reduce pin cushion effect..

You need to use the best quality prisms you can find, so there is a premium to pay..

Re: Making A DIY Anamorphic Lens

Anyone have or know someone that has used this lens? And if so what are the thoughts? It uses 4 prisms.

Re: Making A DIY Anamorphic Lens

I know of many people who have Marks new Mk.3 lens..In Aus, UK and the US and ALL are very impressed with the quality of the build and the image it produces..
It's right up there with the best of any 4 element prismatic lens..and very reasonably priced..

Re: Making A DIY Anamorphic Lens

I've not posted in a while and thought some might like to see the latest developments.

The CAVX Corrector


And of course the best of the best, the MK4.

It is pretty impressive when you can see pixel structure on an AT screen.

It seems I can not attach images, so here is the link to the image I am referring to. Click on the with the word "FOCUS" in the centre. If you look closely, you can see fine lines in both the Horizontal and Vertical lines of the Test Pattern. They are the interpixel gaps of a 1080 DLP.

Re: Making A DIY Anamorphic Lens

Quite remarkable Mark..
You certainly have come a long way with the advent of the Mk.1V!
How are sales going?..It seems that there just isn't the interest in anamorphic projection these days..
I've also noticed that there's not a lot of A lens activity on the AVS forum these days either..

I think a lot of people who had considered going anamorphic, are now looking more at the preset AR projectors, as a cheaper alternative..

Good luck with the new lens..

Re: Making A DIY Anamorphic Lens

There is plenty of interest, just not too many people prepared to pay the price for a high quality lens.
