Amazing thread you guys!

I've been mulling over binos for the last month non-stop to see what's what. Kerry, congrats on those Vortex Vipers. I am very interested in the 10x50 Vortex Viper HD, even though the AFOV is only 50 something degrees. I tried a pair in a store just down the street form me a couple of years ago and I was blown away at the sharpness.

About 10 years ago, maybe longer, I had a pair of the Pentax 16x60s PCF WP ( I don't think they make the 16s anymore). I ended up sending them back because the apparent field was so narrow for binoculars at only 44*. I knew that going in but thought I'd try them anyway, but it was tough to fit objects like the Pleiades and Double Cluster in the field.

Pentax makes great glass so I never quite understood why they kept the field so narrow on the PCF series. The image they put up was very nice. In fact after a while I actually wish I would have kept them. The price was very reasonable, but I was in full wide-field mode at that time so I parted with them and exchanged for something else.

I also used to own the Pentax 16x60 PCF V's, (I believe they were called.)

Super-sharp views, but a narrow AFOV. Wish I had of kept mine as views of Luna and other targets were super sharp.

Hard to tell with photos but that edge performance sure looks good.

All true.

The apparent field is only 44 degrees in those, so i guess that's why. lol.

But, those 44 degrees are pretty much sharp to the edges.

Good contrast, too. Marcus, you had the original PCF design, and available in Mk I, II, III, IV and V variations. Eventually they took the PCF V, improved the seals, and renamed it the PCF WP. I have the PCF WP II series, which was a completely new version. The optical barrels were squared off, and the entire bino is covered in one seamless casing.

These are't my images, but they do a good job to show the difference:

The older PCF WP design:

The PCF WP II version:

Optically they were supposed to be identical, although I've heard reports that the PCF had better QC than the PCF WP II, given the older models were supposedly build in Japan before they move later manufacturing to China. That's less of an issue in current 2017, but was definitely still apparent over ten years ago. Mine are fine, but I've read reviews that go in both directions regarding the symmetry of astigmatism correction between left and right sides in the Mk II. Could be the eyepieces, if I were to guess.

Anyhoo, the classic narrow orthoscopic field does keep aberrations down for sure. Mine exhibit very little with regards to astigmatism or CA, although they do possess notable rectilinear distortion (pincushion, specifically). Always a trade off somewhere. I still think about those Vortex bins, but try to keep the spending to a minimum these days, given that I really already have everything that I need. Besides, as always, I think another truss dob project will be in the works soon.

Nice bins Jay !!!

I have a pair of Pentax PCF WP II on the way. I'll post a few pics and impressions of them when I get a chance. I used to own the 12x50 PCF WP II's and thought they were excellent.

Here's two pics of them here. In fact, I traded the 12x50's, (seen here), for the 16x60's, (seen above)...LOL !

Nice, so you have experience with both. In your best estimation, is there any remarkable quality difference between the older ones and the newer WP II series, regarding either IQ or fit n' finish?

IQ?

Is one bino smarter than the other? j/k LOL

Or did you mean QC?

:lol: Well, Pentax is considered magic to many, so maybe there is some hidden intellect... :razz:

IQ is a term that probably stems from my camera background, but should apply. Short for "image quality".

Ahhhh, I see what you mean now. I'll post a mini-review once my 10x50's arrive and see if I can compare to my older pair of 12x50 V's from about 20 yrs ago....(I will need luck with that memory, lol).

I wish I'd have kept my Pentax as well.

As an update I also grabbed the Vortex 8x42 Talons. 8.1* TFOV. I do not see much difference in performance compared to the Vipers, but the increased AFOV & TFOV are very nice. I tend to use them more than the Vipers for that reason. The Vipers do edge them out slightly optically but IMHO not enough when you take the field size into consideration. The Talons are just more aesthetically pleasing. The MW sweeps are killer.

Mark, the field sharpness and EOF on that bridge pic is sweet. I do regret selling mine. Can't find the 16s anymore.
