A Pentax ortho record?
      #5846611 - 05/07/13 09:01 PM

Two nice SMC orthos sitting all day on the other site at reasonable prices from a well-known seller. Must be a record.

Now the Nikon ortho didn't last more than a few minutes, rats!

It was tempting, but the focal lengths were a little too small for me.

With the Pentax SMC orthos, you always have to be careful that there is no dust specks between the lenses. They had a reputation for these and I purchased two that had them....very annoying.
That fact may shy some buyers away.

Was the dust between the singlet and the cemented triplet, or embedded in the cement? If the former, it ought to be a 10-minute clean-up job I'd expect. If the latter, foggetaboutit.

Reasonable? They're $300! I've seen whole sets in original packaging go for $1300. I'd say that's average to high in price.

That 25mm Nikon Kellner, on the other hand, is a gem. The 25mm Pentax SMC Kellner, on the rare occasion that one is available, goes well over that at auction.

Things have gotten highly erratic in Pentax SMC ortho pricing, as well as TMB Supermonos. Glad I got mine several years back!

Jim, I was mindblanking on the Nikon Kellner, I kept thinking Pentax for some stupid reason. Interesting...

Pentax had serious qc problems. Some of the SMC orthos had not only dust but fingerprints and hair (!) between the elements. It was enough of a problem that two different companies offered a "clean the inside of your SMC" service.

300$, crazy price. I can't explain why anybody would pay such a high price for that eyepieces.

Jim you're dating yourself. The SMC's have crept up to the $300 and more mark over the past couple of years. I see a Chinaman has a want ad out for $400 and it appears several have sold over the past year for over $300. Aknowledged as a "poor mans" Zeiss these are becoming a hotter item.

The XO 5.1mm and 2.5mm are about the same price as some of these SMC Orthos. I hear the XO's are better performers. Personally, I can vouch for the XO's, but have never used the SMC Orthos.

So what you're sayin', Jim, is that a guy could auction a complete set, including the rare 25mm SMC Kellner, for a bundle?



Also, if two different outfits were offering a cleaning service for SMC Orthos back in the day, that would imply that the contaminants were between the singlet and the cemented triplet and not embedded in the cement. That, in turn, means that anyone could pretty much clean their own with minimal effort. Personally, I've seen a bunch of them and never seen a dirty one.

As to why one would want to own them, I find them to be every bit as good as the SPLs, TMB Supermonos, CZJ, ZAO I and ZAO II Orthos, XPs and XOs, and until recently, considerably cheaper than some of those listed. They are the ultimate double star eyepiece. Color saturation, peak transmission and glare suppression are superb.

It's unfortunate that the prices have climbed so much. At $300+ a pop, there are lots of options providing similar performance.

Regards,

Jim

Although SMC’s are not at ZAO quality, they are not too far behind, and at about $300 they represent a far better value than ZAO’s that sell for 2 to 3 times that amount.
Additionally SMC’s offer focal lengths that are not duplicated by ZAO’s, such as 7, 9, 12 & 18mm, and I would venture to guess that $300 is their current lowest price and their values will climb to $400 and above range before too long.

What are the differences between the XO and SMC?

The XO 2.5 has 6 elements in 3 groups, the XO 5.1 has 5 elements in 3 groups. They are JIS Class 4 weather proof. AFOV is 44 degrees. Lanthanum elements. FMC ("SMC") coatings. 1.25" format.

I'm not sure about the specs for the Pentax Ortho SMCs. 4 elements in 2 groups? FMC ("SMC") coatings. 0.965" format.

Some observers prefer the XO to the Pentax Ortho. Some prefer the Pentax Ortho to the XO. Some say the XO is at the level of the ZAO. Some even prefer the XO to the ZAO!

Judging from my own experience with eyepieces and reports I've read, I think at least part of the equation - probably more than some observers seem to think - depends on the object observed. A great Jupiter eyepiece is not necessarily a great doubles eyepiece is not necessarily a great lunar eyepiece.

Oh, yeah. And think about if your collection was fleshed out and bracketed with the two EP's and the K40

Yep, premium glass prices have been on a crazy tear in the past 5 years. Other than the Nagler zoom, everything here seems to have appreciated 50% in the 3 years since I started my long-term planetary optics comparo (making it bloody expensive to complete some of the sets!).

At this rate, this little set will be worth $1.2 million when I retire in 30 years. Sweet (insanity).

I have the two XPs. That 40mm, though...



Oh, 100mm Masuyama anyone?

No 60mm SMC Kellners for you boys? Go big or go home

That and the 24mm XP have proven elusive. I had a 24mm in my hands in Japan, but 20,000 Yen seemed crazy at the time...
