New to Fuji! What lens q..

The 27mm is a lovely lens, but you have to want what it offers: small size, light weight, wonderful pointability (more on this later) and above all, that wonderful,fresh 40mm field of view. Again, it is not to everyone's taste, but there are those who have a deep down liking for it and find it a close to perfect general purpose focal length.

The focus speed is what it is. It is not an action lens, but It's certainly not noticeably slow and I dont find it a problem. Noise? Nothing compared to the 35mm f/1.4 and I love that lens. F/2.8? That's how you get it small, and there's more to a lens than a large max aperture. Note that its forward weight is almost nil, making it very easy to hand hold and get some of those stops back in shutter speed.

But I'm not here to try to sell you on the 27. (Much as I would personally do a lot to get my hands on that mk 2 you take so casually. They are almost impossible to find here in the States from a reputable source.) I would suggest the 35mm f/1.4, which gives you the large aperture you want and excellent optics, but if you don't like a noisy lens, that's out.

But then there's the 50mm f/2, which I can recommend wholeheartedly - well made, quiet, snappy to focus, sharp, nice rendering, useful close focus-- an excellent lens in every way. The very mild telephoto field of view it offers is perhaps slightly unusual on paper, but it feels very natural from behind the camera and yields fine results.

I have the 35mm f/2 but am not entirely pleased with it. I keep it to use on an old X-Pro1, and it is well suited to that camera. It is also fairly small and shares the quick and quiet autofocus of the 50mm. But I find it rather bland and boring, even dull, and would choose either the 27mm or the 35mm f/1.4 over it every time.
