I recently joined Cloudy Nights because I am working up a history of astronomy course for young people (age range not yet determine). So I wanted to buy some equipment for helping the students get acquinted with the night sky, look at some spectra, and also safely look at the sun. I was very impressed by the comments on the Fujinon 10X70 binoculars so I purchased what was advertised as a used pair in good condition for a little under $600--not exactly a bargain, but OK. Upon receiving and opening the box, I took a look at the night sky and could not converge the images of the moon although I have no trouble doing this on several others (less expensive binoculars I own). I noted the when the image on the left eye is centered, the right eye image is displayed far up and over. It appeared that the binoculars had been dropped, and in fact the metal was exposed on the outer rim of the right objective.
I then compared the binoculars with photos on sale pages and noticed significant differences which may indicate that I had received an old model. However, among the many images on Google I could not find a pair that resembled what I had purchased. Then I obtained a pair of FMT-SX 10X70s for comparison. I provide a description and perhaps someone knowledge can give me their opinion. I intended to add a few photos but they don't seem to be loading. I think the descriptions are sufficient, however. I'll refer to the known genuine pair as G and the pair I bought as Q.
1,The distance from front to back on Q is about an inch longer than on G.
2. The field on Q is indicated to be 5.0 degrees; on G it is 5 degrees 18'
3. The case for Q is generic without writing; the case for G says in large letters Fujinon with Fujifilm under.
4. The disk on the front of the pivot on G is inscribed in white for the angle markings with a long serial number (letters and numbers) in yellow and Made in Japan under; on Q everything is in yellow, the serial number s just six digits and instead of Made in Japan is the word Waterproof.
5. The plastic cover for the eyepieces lenses on Q has no writing; on G, Fujinon appears on the left cover in letters raised from and molded into the plastic.
6. The long tapered tubes which extend from in front of eyepieces the front end of the Q binoculars have long raised ribs (about 1/4" wide) and abut 6"-8" long on a smooth black background; on G the surface of the tubes is pebbled plastic (common to many binoculars).
7. The cover for the mounting threads in the pivot (the removable disk) says Fuji Fujinon is dull gold on a screw on disk in Q; in G the disk says Fjinon Fujifilm Made in Japan in bright gold lettering on a skisks that pushes in by a center protrusion that goes in the threaded hole.
So have any of you encountered genuine FMT-SX 10X70s that resemble Q--the pair I received?
I am returning them (or rather asking for a refund) based on the severe out of collimation problem. But I also suspect that they may be a cheap Chinese knock-off such as exist for so many name-brand products.
