Yep, this is the Rayfact version of the legendary 95/2.8 PN, this one is rohs compliant. Having 2 magnifications for both ways of mounting seems to be popular among these types of line scanner lenses (see Linos inspec.x).
I'll get some samples up when I come back to Australia. Currently in an apartment, can't get sharp results without a decent setup. Fair amounts of tubing was needed to reach 2:1. The resolution at 2:1 is insane however, being able to fully resolve the fine details in the wafers, down to those dense lines that many lenses struggle with even at higher magnifications (ie laowa 25mm).
The big image circle would be great for some shift panorama stitching. I only have a Mamiya 345 auto-bellows now, sold off my pb-4 copies.
Do be careful with Chinese sellers on eBay. Many simply steal photos from taobao and list the item at staggering high prices. If someone is unfortunate enough to make a purchase, they will just buy it off the taobao seller and flip for profit.
