My previously used x10 binocular is the SFL 10x40. I really like the slim barrels of NL 10x32 compared to the SFL 10x40 even though the weight difference is not huge between them. I like the bit more FOV of NL too. However, SFL has better colours and contrast, the browns are more saturated in SFL. As well as it has no problem with glare. Overall, I prefer the ergonomics of NL so planning to sell SFL soon.
The NL 10x32 is dimmer during low-light times compared to the NL 8x42. However, when compared with the SFL 10x40 the difference in low-light performance in NL 10x32 is much less. The NL 10x32 is perfectly suited for my birding habits however, I carry a Habicht 7x42 during low-light hours.
