Now I have the SLC 8x42 and the SLC 10x42 newest editions! I just love the SLC 42. I have NL and EL as well, but the SLC are more comfortable in use. The more binoculars I tried, the more I value comfort. The eyecups of the SLC's are just right! At least for me. Not too wide, not too narrow. No blackouts. I don't have the feeling the eyecups miss a position.
I already loved the SLC 8x42, but since I am a 10 power man, I just couldn't resist an offer of a used SLC 10x42. They fit me really well, as the 8x42 does. What I liked about the SLC 8x42 too, is it's compactness and its (light)weight. The SLC 10x42 is even a bit shorter and a bit lighter! The eye relief is shorter on the 10x42, but I don't wear glassed so I don't care. I you wear glasses, the 8x42 would be a better fit.
I might sell the recently purchased EL 10x50 now.... and the NL 10x32... The SLC 10x42 is the perfect allrounder: lightweight and very usable at dawn!
I would miss the very very nice focuser of the NL 10x32 though (the difference in weight is just 100 grams: NL 10x32 is 670 grams, SLC is 765 grams.) I would miss the 5mm EP of the EL 10x50 too, but for that I have the SLC 8x42.
I don't care about field flattener, I don't care about huge FOV's. I thought I would, but after field experience, I don't care too much about that anymore. I do care about eyecups that fit my eyes perfectly. The hold, the ergos.
I promised why wife to sell the SLC 8x42 (I prefer 10 power), the NL 10x32 (not compacter and really lighter than the SLC 10x42) or the EL 10x50 (the SLC 10x42 is also really usable in at dawn and much lighter). However, I still don't not know which one has to go.
However, I got the SLC 10x42 just one day and I tried the diopter and the focuser/diopter came loose. It is just not tight anymore. I don't know what happened. Focusing is hardly possible anymore. So I have to send them to Austria and have to wait 6 weeks or more... I can postpone my decision and hope my wife will forget my promise.
No, I also think one has to go, the one which I will use the least....

A SLC fan
