I own the 7x42 Habicht, but until two days ago, had never looked through either the 8x30 or 10x40. I'm also using my 8x32 SF almost exclusively at the moment, having discovered how much more of a joy it is to use in the field without glasses, than with.
Then, on the Monday just gone, I had the opportunity to test all three Habicht’s side by side, comfortably, because I no longer
need to use glasses. The 7x42 was more comfortable viewing without glasses, than with, and the view even better than I remembered from the last time I used my own copy. The 10x40's I preferred, a far more immersive experience than the 7x42's, mainly due to having a less tunnel-like view. But the 8x30's? OMG just WOW WOW WOW, what a view!!! I NEED a pair of these! For the view, they are surely the pick of the three and the sweetest in the line, although I'm aware they have a reputation for generating glare under certain conditions. Really, just wow.
@Maljunulo, no wonder you are using yours for five hours a day, every day. I'm amazed you ever put them down. Congratulations!
For me, they are a revelation. I'm in love I'm in love I'm in love I'm in love...
