How and where did you managed to get that low? 

For 1st question, the x70 is smaller than the x100t due to lack of viewfinder for the x70 but it had swivel screen that can flip up for taking selfie (*Call it whatever u want  ) which the x100t had a fixed screen  . The x70 have a 18.5mm fixed lens while the x100t have 23mm (28mm & 35mm in term of full frame lens equivalent), it a tad wider that some prefer than the other. What interest me for the x70 is the conversion lens u are able to buy for the x70 which change the lens perspective to 21mm in full frame format  , which is good for wide angle shot (**The x100t has conversion lens that equivalent to 28mm and 50mm).

2nd question, not sure about the difference between XC and XF lens, but I tried it at the shop and the quality of pic using XC lens is good, nothing to complain about  . Lens wise, I can get macro shot as near as 10cm from the subject with x100t, I'm pretty sure the kit lens cant do that  (Correct me if I'm wrong  ). I don't know how  far is mount fuji and the lake, but the best bet for wide angle shot is the x70 and the conversion lens but that will exceed ur budget I guess(**Need clarification on this, does x70 plus conversion lens goes beyond RM4k)

Yes x100t has flash built in, might not be strong enough, but can try bounce the flash using small mirror if u are indoor to get that external flash look  . I bring tripod in the luggage bag for trip but never got it out cause it a hassle to bring big tripod around while u are touring  (PS: I do bring my joby gorilapod tripod in my bag cause its smaller that my regular sturdy tripod  )

To answer your question regarding X70 vs X100T.

The X70 is a small camera and it's quite handy for travels. You can fit it in your pocket and doesn't even take space in your bag. X100T is bigger. Still doesn't take much bag space but you'll have to hang it around your neck.

You'll have a large articulating touchscreen which is perfect for selfies, but what interest me more is the ability to select AF points on the go. Personally, I feel it's quite handy that you don't have to press any button or rotate any dial to select focus points. Advantage against the X100T? Yes, for touchscreen. Negligible for the articulating screen.

Plus, it comes with Classic Chrome, which I love to death when I had the XT-1.

You'll have a wide fixed lens which is perfect for landscape, a tad too wide for street, I guess the X100T would be a better choice for street. For both cameras, it's quite restrictive in terms what you can shoot, but in a good way, it helps train your composition skills. Also, with the fixed lens, you'll most likely avoid having Gear Acquisition Syndrome (GAS), and spend less. There are lens converter but I've never find any need to purchase one.

Regarding the lack of viewfinder, I was worried that this could be a turn down, but it turned out fine transitioning from the XT-1. It didn't bother me to see everything through the screen, by the way it drains your battery. You would need extra batteries or a powerbank to charge on the fly. I have 2 additional Wasabi batteries and a separate charger. I've gone on commercial sets, taking "behind the scenes" photos and videos with the X70 and I ended up using all three batteries. A disadvantage, but still you can workaround it.

Is the X70/X100T, a good beginner camera? I don't see why not. you'll still be able to do everything manually for you shutter speed and aperature. You'll have the ability to do manual focus (FYI on the X70, the focus ring is quite small and could be troublesome sometime, but I rely on the camera's AF). ISO, you'll have to go through the "Q" menu.

Lastly, the X70 is way cheaper than the X100T.
