>>407849318 f1.4 is the best hands down
16 f1.4 and 23 f1.4 are both solid, and since you have a 35 already, that would push me to recommend the 16 more of the two
18 f2 and 23 f2 are okay, not great, but fine for what they are, and I often either miss f1.4 or simply being sharper at f2 like you get with the above
16 f2.8 is pretty underrated imo, tiny and solid optically, just f2.8
own all but the newer 23 f1.4 wr if you want side-by-sides / samples
consider too that the f1.4 will go into the OVF a fair amount, and you start to lose framing with 16-18mm
>>4078739i'd probably prefer the 12mm f2 over the 18 f2
also consider the 16 f2.8, much slower but pretty decent optically, tiny and wr
ttartisan 17 f1.4 is a good combo of size and speed, but not sure how well it handles coma for stars
