I'm using LR 6 standalone and I like it as a converter, I just wish it wasn't so devoted to cataloguing. I follow up with CS5 as necessary and still keep Capture NX2 which I love but which cannot convert Fuji raw files so It's use is for tif/jpg only.. Don't write off Silky too easily - I hated LR when I switched from CS5 but just had to forget the PS way of doing things and now I wouldn't go back. Silky interface is clunky if you're used to PS but if you used Silky first I'm sure you'd find PS even more complicated so you just need to blank out the PS way of working for a while. There is no "logical reason" for not liking the Silky way just our mindset. You may well find you want to purchase the full Silkypix.
Due to the X Trans sensor being close to ideal for IR the Fuji X cams are much used for this medium. I currently shoot BW & colour using a standard Hoya R72 filter and have examples in this forums gallery. It looks as if this dedicated camera will still need filters in order to differentiate between visisble, IR and UV light. It can also be used (with an IR light source) for night photography) . It is rather a lot to spend if one is using it for specialist photography such as scenes of crimes though and an XM1, XE1 converted will be cheaper assuming only IR is needed. It is much more expensive to have a conversion for UV and visible lights too.
I'm sure I answered this about 10 hours ago - I think I must keep hitting the "insert other media" button - not for the first time.. Anyway, what I said was along the lines of - It may be the OIS so try switching that off or maybe you have selected Pre AF and CAF which will cause the lens to continually refocus as it's moved. I don't get this myself - at least I don't notice it but I have heard of the problem. All those things will also cause a more rapid battery power drainage.
I never used one of these super-zoom types either film or digital. I think most of us came from backgrounds of DSLR and many from FF DSLR wanting to downsize to have the benefit of a lighter system and of the "retro" controls (esp us old 'uns) but would find the X-S1 too much of a step down in terms of IQ, controls and AF (no good for moving subjects whatever X-S1 lovers might say). I'm happy with the APS size of the Fuji sensors but I wouldn't want to go smaller. I have seen some very nice images taken with X-S1 but I've always been left feeling "if only they'd been taken with a larger sensor camera". At more than small web size the images don't hold up for me - although as most of our pictures end up on the web that should be enough. If I was willing to accept a smaller sensor then X10-20-30 range would probably me suit better. I always felt the X-S1 was somewhat of a misfit in this forum but then it would be even more of a misfit in the Fuji P&S forums. Since the rangefinder style Fuji cameras were introduced I guess the X-S1 changed from a swan to an ugly duckling. There are other owners/lovers of it but perhaps due to its short sales life not as many as it deserves
Do you have Pre AF / CAF selected. Also the 18-55 has OIS so try switching that off or switching it to activate when shooting only. It is often combinations of settings that cause high battery usage. However if it seems your settings are not a problem (if necessary try a reset) then take it back to the store for them to sort out.
Maybe the new smaller 35mm f2 will have aperture ring and distance/DoF field scales. Since getting the 14mm I decided I will only use this type of lens of and below standard 50mm equiv even if it means I have to buy old legacy lenses and shoot all manual (which I mostly do at those FLs anyway). BTW I use the 14mm for street stuff - you just need get a little closer and often I shoot from the hip.
