Maybe it's just me but I received it today, mounted on K-5 and took some test pics with a manual lens. I got stunned. The thing wins hands down with Pentax "live view" for precise manual focusing. It's quite well manufactured. Optics are first class for me. Pentax adapter fits snugly my K-5. Settings with test pictures matched exactly : one with calibrated CIF and one with manually focusing the subject using Seagull finder. Both were right on money after I magnified the two pictures 32x.That's what I needed. And I don't care for negative reviews by various "photography experts" from Amazon dot com.
Amazon.com: Seagull 1x-3.25x Angle ViewFinder for Canon, Nikon, Minolta, Leica, Pentax and Olympus DSLR SLR Cameras: Camera & Photo
I actually purchased "amazon warehouse deal" from the same site. I just took a shot - what wrong may go with that kind of stuff ? how badly abused may it be ?
I was sort of lucky : the thing is actually brand new in factory sealed box. Most likely some teenager got it as a Christmas present from some remotely related cousin and couldn't find any use of "curved monocular"

Then sold it to Amazon or traded for same duke nukem...
It registered in my wallet @ $29 plus free shipping.
I strongly recommend.
