Yes, I had an SE 10x42 once, and I thought it was a very good binocular. I remember it being very bright for its aperture. If it is right up there with your alpha 10x42s that is quite impressive. The 6 degree FOV is average but not bad. The 10x42 SE never got the recognition its more famous brother the 8x32 SE did.Dennis,
The SE 10X42 is an excellent glass even compared to premium glass today, it has a 6 degree FOV that to some is narrow, however it is all usable. Additionally it is also a high transmission glass. I believe Roger Vine still has and uses one to this day. I have an early and a late model in the SE 10X42. The Nikon SE is the only porro I use on a regular basis, all three formats, and they are right up there with the few premium 10X42s I currently use.
