Lens selection for x cameras... Suggestions

Thanks everyone, that is very helpful.  I won't be exposing it to prolonged salt water exposure,  only a few seconds or two of spray,  I'm getting an Xt1 as well and have ordered the water proof diving case for it for very heavy weather.

But in very bad conditions I usually use the GoPros because should they get washed off their mounts it's not a catastrophic cash crisis to replace them!

I find it interesting the debate around 'retro'  with this camera. Yes,  many of the design features are old fashioned for example the iso dial which was very common on rangefinder and some slr cameras in the past. Personally  prefer making adjustments using dials rather than menus,  one of the reasons I loved my old Leica and my Russian clones is that the use of the dials is highly intuitive.  Compared to scrolling through some bloody menus it's a breath of fresh air.  I guess I am a 20th C guy through and through.

It amuses me that some speculate whether use of dials like this is a fashion thing..  The position and layout of the duals was perfected over 80 years of camera design, and are thus because of decades of trial and error,  it's just that we forgot that actually these layouts worked really well.  Progress often throws the baby out with the bath water,  look at what happened to beer in the UK in the 1970s, we forgot our real ale heritage before rediscovering it. Or the digital watch which was meant to have killed off the analogue by now,  Quartz was definitely meant to kill off clockwork but it didn't and people spend thousands on watches which are less accurate than a 2 dollar quartz movement,  (unless it's a George Daniels Co Axial!)

II'm a huge fan of new tech but I also like it when new tech takes the best of older and compliments it. To a middle aged git like me I like the familiarity of the old tech for the same reason that computers have qwerty keyboards 30 years after the mechanical necessity of the typewriter was redundant. (ok,  I do use a 1923 remington portable which I have rather sadly adapted to record key strokes on an sd card giving me a digital copy of my typing).

And no one is going to convince me that the keyless start and entry on my wife's car is an improvement on the 4000 year old tech of the key and key hole!!!

And don't get me started on electric parking brakes!!!!
