Kelton,

I purchased a pair of Olympus EXPS 7x50 binoculars (for astronomical
observations, primarily) about two weeks ago. My only point of reference at
the time was a pair of Pentax 10x50 binoculars that were roughly the same
price (about US$190, converting from Portuguese escudos) which were a little
larger/heavier and somewhat inferior in terms of build-quality.

In terms of optical performance, I wasn't able to detect much difference
between the two models in the shop, but the salesman didn't hesitate to
recommended the Olympus over the Pentax, claiming that the Olympus' optics
were "superior". Well, since I already knew from the Olympus web site that
this model employs BaK4 glass in the porro prisms, and perhaps out of a
sense of "brand loyalty", I opted for the Olympus model :-)

So far I've not had many opportunities to use them, but one characteristic
that's quite evident is a fall-off in image quality towards the very edge of
the field of view. I find this not to be too much of a problem, however, as
I generally have the object of interest centred, where it appears nice and
sharp!

I've never used the Adlerblicker or Celestron binox you mention. Do they
also exhibit image quality fall-off towards the edge of the FOV? Are they in
the same price range as the Olympus model?

One word of warning: two of the three models in stock at the shop had small
specks of dirt/paint on the _inside_ of one of the front elements. Could
indicate a quality control problem?
