Vacuum Film Holders

[mikewhi]

Anyone have any experience with these, especially regarding ULF sizes? Have you seen any with manual hand pumps that might maintain a vacuum for 10-15 seconds or so? Do these things work? I have seen a picture of what I think was a Huffman MetalMaster with a vacuum nipple on it on eBay once.

If I get into 16x20 cameras, I am just wondering if this is a viable solution to film lag\bulge in the holders.

Thanks.

Before you do that, talk to Jim and how his holders work. I think he has the sagging problem licked.

I've tried, but I cannot get any info on the camera, holders, etc. So, I'm exploring options, thus the post.

I'd be interested in anyone's knowledge, first or second hand, of vacuum holders.

Thanks!
