The Ritual Basin

I like this. I've flipped the lens in my Hawkeye. An easy task. How about the Cresta II?

On the Cresta one dismantles the shutter and lens assembly and is left with a conical plastic lens holder. In the front there is a metal washer holding the lens in. The advice is to push hard on the back of the lens with a padded chopstick or something to pop off the washer and remove the lens. But I had a hard time pushing the washer out and came to doubt the lens could be removed from the front. This NOT recommended, but I resorted to partially drilling the washer, weakening it so that it would flex and come out. But I was able to conclude that the washer does come off and lens can be removed from the front. If someone did a better job pushing lens out it might be fine, but was for me a little harder than Hawkeye. I got the Cresta II, but am now wondering if I should have gotten a Cresta I because reportedly the first has an f/13 aperture and the later one a f/11 aperture. But it sure is nice that the Cresta natively takes 120 film. Not only does it have a build in yellow filter and closeup lens, the lens housing will also accept Kodak series push-on filter holders just like the Hawkeye. Then you could either the use actual series filter inserts or use some step-rings to set it up to use conventional screw on filters. https://www.flickr.com/groups/flippedlens/discuss/72157666387244478/

Thanks for the detailed info!
