Two and one-half years ago I purchased a PE-80 ED angled Pentax scope. The main reason I reason purchased the Pentax was that it was one of the very few scopes that had decent eye-relief. I believe now, however, that the top companies are providing scopes with better eye-relief than they were 3 years ago.
This is my first scope, and the optical quality is fantastic.
The only downside is that it is slightly longer than some top scopes, but I paid $850 for the scope AND eyepiece, where the the
Leica, Seiss, and Swarovsky cost $1,300 to $1,700, not including the eyepiece.
The Pentax does not have the two focusing wheels, like the Zeiss. Although I have never used a scope with a fast and a slow focus, it sounds like a great idea.
I purchased the angled version after much research. All the articles I read and all the comments from my friends suggested that angled was better than straight because t is easier to use and the tripod does not have to be raised as high. The only downside to an angled scope that I have found is that when I have the tripod set at a height that is best for me, a person much shorter than me cannot get high enough to look down into the eyepiece.
Finally, considering the optical quality and the price of the Pentax, I believe it is a great scope. With the Pentax you are getting a great scope for less than half of the others. Especially considering that I do not use my scope that often, I did not want to spend $2,000.
