Just wondering - I currently use a trio of primes - the 14, 20, and 45 f/1.8. I love that I can fit it all in a bag barely even noticing. It covers basically all the situations I need. I've pondered swapping the 20 for the 25, but haven't gotten myself to pull the trigger, mainly because it would add bulk. It got me thinking though, instead of putting the money toward something like that, would I be happy with a two prime kit, a mythical 17mm f/1.4 and the 45? I think I would - and I figure the cost of the 17mm would be somewhere in the range of the 25. Does this describe anyone else here? Would a fast, native 17mm eliminate the 14 and the 20/25 for you? Curious for your thoughts. Thanks.
