Clones—Pentax 8x32 ED DCF and Opticron Imagic 8x32 BGA SE? (1 Viewer)

The Opticron Imagic 8x32 BGA SE and the Pentax 8x32 ED DCF look very similar to each other. The cheapest I've seen the Opticrons is £340 as against £500 for the Pentax, so if they are clones, then the Opticrons are a pretty good bargain. Alternatively, the Pentaxes are grotesquely overpriced.

The specs do not match

Opticron Angular field of View 8.77 degrees
Pentax Angle-of-view 7.5

But go for the Opticron firsT. If not happy, trade to Pentax.

You can't tell if two bins are clones just by looking at teh case design. In some bins it's just a similar design case. In others they're using a common case component so they'll have the same dimensions. But the specs never lie: FOV and eye relief all tell you about the eyepiece design. Weight tells you if they really are the same (or at least have the same amount of glass or ballast inside!)

So they don't. The thing is...the thing is...I put the Opticron in by mistake! I meant to point out the similarity between the Pentax and the RSPB HD 8x42. Both exactly the same price too. I'm very sorry for having wasted your time.

I'd say no but they are quite close but the close focus and height are different (13mm). As is the weight (but who weights accurately to 5g?).

Sometimes can't tell with the FOV measurements either. They seem all to move in 0.5 degree increments. Funny that!

But the RSPB bins are usually Chinese OEMed so I wonder who is making them and if any of the US distributers are picking up the same bin (say in the same way as the Sicong Xi'an Navigator is on both side of the Atlantic under a variety of different brand names).

This sort of ties in with the "Mystery Bin" on the 8x42 thread. Another Chinese bin with ED/HD glass. Obviously a trend for 2009.

The mystery thickens!

Me too. I obviously conflated the Opticron and the RSPB and made up a non-existent bin. I hereby officially retire from the clone-spotting business and once again apologise for wasting everybody's time. If could have deleted this thread I would have.

To me they look totally differently.

That would depend on their optical performance!
