In my FF film days, I had always enjoyed using a 24mm prime and, although later (with a DSLR now) I acquired a 10-22mm (14-32mm equivalent), it was the prime I favoured as a general lens.
For quite a few years I hardly used these cameras at all, prefering to use a decent compact. Then I discovered the Olympus PEN! The first additional lens I bought after buying my PEN e-pl3 was the 9-18m to recapture those wide perspectives. More recently, now with an OMD em10, I have added the 25mm f1.8 and 45mm f1.8 to my setup and I must say, IQ aside, I am enjoying the primes over zooms.
My dilemma is this: I am very taken by the prospect of the 12mm f2 prime but, given the cost, I would almost certainly have to sell the 9-18mm to fund it. Like most people here, I suspect, I use wide angles for a mixture of landscapes and interior shots. Clearly, for the latter, if the 12mm was wide enough, I'm sure its speed would be a real benefit but would that outweigh the lack of the extra 3mm?! Aaargh!
Any advice/thoughts (especially from anyone who's used both) would be much appreciated.
It's hard to answer because only you know what you like to shoot and what you need. If you already have the 9-18, then you already know how often you need/want wider then 12 and if you would miss the 9-11 end. On the wide end, that makes a big difference, just like 12 is a bit wider then 14, but you would not see a big difference between say 48 and 50.
Not sure if you have spent any time looking through you pictures. I always recommend doing an inventory of your pictures to keep note of what focal length you actually use the most.
An example, I'm new to M4/3, but did a review of what focal length I tend to use the most on my 12-32. There is a obvious spikes on both end you tend to get with a zoom, bit I was surprised how often I shoot at 12
