The Pentax ED bino's are really a under rated gem! They compare very well to the Alpha's; maybe just a step behind, but for the price-they are superb. I have compared my 8x32 Pentax ED to a Leica Ultravid HD and a Victory FL (Zeiss) and it did very, very well.
I will also say to my eyes that the 8x32 Pentax DCF ED is sharper than the Swarovski 8x30 SLC NEU. And I love Swarovski. I was going to sell my 7x30 Swaro SLC last year along with my 8x32 Pentax ED and just keep a newly acquired 2010 8x30 SLC Neu. But... to my surprise- the 8x30 SLC was not as sharp in the center resolution as the Pentax ED and was not as good in low light. So, I ended up selling the 2010 8x30 Swaro SLC and kept the Pentax 8x32 ED along with my 7x30 SLC and have NO regrets. Plus I would have only gotten about the same money for selling the pentax ED and the 7x30 swaro as what the 8x30 SLC cost me. And I would have actually been worse off than I am now with (2) bins that I use for different situations.
More than you needed to know, but I think very highly of the Pentax ED
