Again, thanks for all the thoughtful replies, information, tips and suggestions. This is really a great forum with amazing people. It has really helped a lot in making this (expensive) purchase (/investment). I'll explain a bit more in detail below, but I am now the proud owner of a pair of Zeiss SFL 8x30's!
Yesterday I stopped work a bit early and went to another shop (recommended by the one I went earlier) to try out the SFL 8X30. Had a really helpfull, knowledgeable birder salesperson, who was patient and also had me try many different models, both cheaper (kite) and more expensive (NL Pure) models so I could experience the difference. They had a lovely garden with sunflowers that attracted small birds, butterfly's, bees, bumblebee's and other insects. But I could also look a lot further to a church in the distance (great idea of the store to have the garden).
The SFL 8X30 were the only pair that I tried (among many swarovski, kite and Leica models) where I had the full view through the bins with my glasses on. I guess I would better switch to lenses, it certainly would be cheaper, but this was for me the major deciding factor. In addition they also felt great and the view was just very impressive. I initially had some issues with the focusing, but then noticed the diopter correction was not on 0. After that I quickly got the hang of it and liked the short throw. I had a spot reserved in my sling-camera bag and although they are not as compact as the CL 8X25'S, they still fitted comfortable, where my 10x42 didn't at all.
I had my mind all set on the CL Pocket 8X25's because they pack down so tiny! The dimensions listed make it look like they are quite close in size compared to the SFL, but that is at a specific inter-pupil-distance-width. When they are packed down, the difference is huge. This almost made me buy the CL's and live with the black ring. However, I packed them down a few times and then tried to get them to be "just right" again for viewing, and it definetly took some time and fiddeling. The double hinge makes it akward to get them right, perhaps especially with glasses? They should make the hinges move together with a gear or something, but now the can move independ wich makes it fiddly. The sales person acknowledge this and stated that in general you set them right when start your hike and then leave them like they are around your neck. I guess you might get used to that but I didn't want to risk it as this would become old very quickly.
I also got to try out the NL Pure 8x32 and I must say I understand why they get such positive feedback. The view through them is on another level, even coming from the already very impressive SFL'S. However they are significantly larger & heavier than the SFL'S, actually similar to my 10x42's. So I didn't spend too much time with them as they were not an option for me. It's hard to recall but I think that even though the eye-relief specification was similar to the SFL's I think I still had a slight narrow black ring. They are also priced way out of my budget.
None of the Kite's or Leica's had I tried had a useable eye-relief distance, so could not be considered.
I had my mind set on the Swarovski CL 8X25 but after having used them next to the SFL's I'm positve I made the best purchase for my requirements. Amazing quality, good eye-relief and still compact/light enough.
8x vs 10x
Just to be sure, I tried many different models in both 8x and 10x. But my initial impressions were once again confirmed that the 8x were the right choice for me. The wider FOV and stable/calm view really convinced me. Initially you think you want higher magnifications, but in reality for my main use the 8x will be just right.
Short distance focusing
One use/specification I had not really considered is the close focusing for watching butteryfly's, bee's, bumblebee or other insects. With the SFL you can focus really close to about 1.5 meter (under 5 feet) which is impressive. Even the NL Pure's only go down to 2meters. A whole new world opened to me!
I will post back after my trip with hopefully a lot of real life experience on our safari trips.
Thanks gain for everybody's great input. Especially those suggesting the SFL 8X30's. To be honest I hadn't considered Zeiss and wouldn't have even tried these without the suggestions.
