Pentax 20x60 PCF WP II Binocular

Postby Bruno on Sat Feb 18, 2006 6:41 pm

Hi I was thinking of buying these here. The usage would be 50% long range observation, 50% astronomy. I am looking to upgrade my current nikon action extreme 12x50's. I bought a pair of oberwerk 20x80 deluxe 2's and loved them(excellent buy) but unforuntally I had to get rid of them for 2 reasons, first and foremost they were stressing my bogen 3011 and 3130 setup, not to mention the fact that they are so heavy the onl;y pratical place to take them would be about as far as my backyard :)
So the 20x60 pentax seems a good alternative for backpacking up mountains and scanning the night sky. So the only reason I am posting is because I can't find too many review on these binos and there is ONE thing that is bothering me, the 2.2 FOV. Could you maybe give me a little info on these binos. Are they a good choice for my application's. I once owned a pair of 100mm binoculars with a 2.5 FOV and they was still great, do you think that the FOV in the Pentax's would be ok for me?

Thank you so much for your opinion's
Bruno

Hi

I would still recommend a tripod for any 20x binocular, especially for a lighter one such as the Pentax PCF 20x60. You'll have a hard time steadying them without one.

At 2.2 degrees, it's a bit skimpy for a 20x bino, but that's part of the price you pay to get that long 21mm of eye relief. I don't think it will cause you any problems, but it won't be as comfortable to scan star fields as a standard 20x80 giant.

Hi I already have a good tripod, because 20x is completely unholdable. Do you know of any 20x70 or 20x80 giants that are somewhat lightweight, and waterproof. You said that a 2.2 fov is a little skimpy for star fields, but will the 2.2 FOV be good enough for some long range observation?

Hi

The 2.2 degree field is more of an inconvenience than a problem. If you have experience using binoculars, should be no problem. Given that the Pentax is the only thing we carry in a relatively lightweight 20x, it is still a good choice for your application.

Hi Thank you so much for your advise. I have been using binoculars for the last few years so I think I will be fine. It is really a shame that more 20x60's aren't made, 20x60 is a very overlooked combo when manfactures make binoculars. By the way, when it come to astronomy, how much of a jump am I going to witness by going from a nikon action extreme 12x50 to the pentax. I have viewed a pentax 10x50 PCF WP II and the optics were so close to my action extrme's that I could barely tell the difference between the 2. Can you verify if the 20x60 can live up to the image quality and build quality my action ex's have gave me for the last year or so?

Hi Bruno

Do I think you will a see a huge difference between a 12x and a 20x for astronomy? No. Not in any serious way. 20x will resolve a few more stars at the edge of globular clusters, maybe make the some of the smaller binocular planetaries like M27 a little easier to pick off or perhaps improve the contrast on some objects by darkening the background, but a difference of 8x in astronomy is not significant. Given that the 20x will be harder to steady and have a narrower field of view, you might be happier and more comfortable with your 12x. Not trying to talk you out of a sale, but I'm just not convinced that a 20x60 will be much of an inprovement of your 12x50.

If you want a lightweight alternative that will open up much more potential for astronomy, consider buying a good 20-60x80 spotting scope. This is an under-rated and under-used instrument that can take you places the average astronomy binocular cannot go. I use a premium spotting scope as a grab and go scope for star clusters and nebuale all the time and have been very pleased with the results.

Jonie That 20x60x80 spotting scope sounds wonderfull, and I would LOVE to have one, but unforntually one of these insturments is way out of my budget, unless there is something else that you can suggest?

Well I think I am going to buy the pentax. One last thing, I have read that the older model pentax, the PCF WP, is better than the newer PCF WP II. Can you please tell me if there is any truth to this? Are thjese 2 binoculars the same in build quality and optics? What is the difference?

Hi

Some people claim that the PCF WP are optically superior to the WPII, but I can't verify this. Other than that possibility, about the only difference you'll see is in the eyecups. The older PCF uses push-pull eyecups and the newer WPII uses the twist up eyecups.

Hi thank you for the response. I have just one last question and I will leave you alone. I said before that I had Nikon Action extreme's 12x50. For daytime use, could you tell me if optically, I am going to be going downhill a small amount, about the same, or even a little better than my Nikon's? I have heard on cloudynights that the coating s were better on the pentax but I'm not sure. I am going to buy these off of you guys because of the excellent service you have. But If you can compair the optics of the pentax vs the nikon I would be grateful. Thnaks so m,uch :D

Hi

No problem. Glad to help. Your questions are good ones.

In theory, the Penatx does have better coatings in that they claim full multi-coating whereas Nikon is a little vague other than to say multi-coating. In practice, I doubt you would ever notice a difference.

As far as I am concerned, if you need more magnifcation than 12x, you need a spotting scope, not a 20x bino. I just don't think that extra 8x is enough to make a serious difference out in the field where it counts. You won't get a great spotting scope for $200, but you can get a useable one in a Bushnell Trophy 20-60x65, http://www.opticsplanet.com/bushnell-20 ... rophy.html It will be light and compact to boot.

Me, too. A good spotting scope makes an excellent grab and go telescope. Only limitation is lack of magnification and the use of a camera tripod as an astronomy mount.
