Nikon ProStaff ATB 10x25 or Pentax 8x25mm DCF SW

Hi,

I plan to buy binoculars to use for travel / nature and animal viewing.

I am undecided between Nikon ProStaff ATB 10x25 or Pentax 8x25mm DCF SW.

From what I read, both are great compact, budget binoculars
> Nikon ProStaff ATB 10x25 is great, but there might be alignment issues - resulting in double images.
> Pentax 8x25mm DCF SW is a roof prism design, no alignment issues - but resolution is not as great as porro prism design.

May I be advised on which to purchase?
Are there any other pros and cons, to make the final decision?

Thank you

You won't notice any difference in resolution between roof and porro unless you are in an entry-level price range, and then, maybe, only if the binocs are on a tripod trained on a resolution chart. Glass and coatings make much more difference than type. I'm a Nikon fan, and the Prostaff 10x25 ATB is a good performing binocular, but in this case I like the Pentax 8x25 DCF SW because it is a much handier and ergonomic product, besides having a larger exit pupil which is extremely important in subcompact binoculars. Also, the 21mm eye relief is substantial and forgiving. Super easy to carry, also.
