Buying the X-T2 or the X-T20

Although these two cameras share the same lens stable, sensor and processor there are some items that do vary, when you compare specifications. However, this does not really tell the whole story, and necessarily help you decide which camera to buy.  So the following are a few general scenarios that might help focus your decision.
Budget Conscious 
If you are on a budget and getting into Fujifilm equipment for the first time, the X-T20 might be a better choice than the X-T2. In this kind of a situation, one usually acquires a kit lens with the camera and often this means you do not have enough money left to buy a prime lens. This leaves you shooting with a zoom lens without the advantages of a prime lens. If you buy the X-T20 over the X-T2 kit you would saving $800 CAD. There are two possible kits with this camera and I would suggest the 18-55 f2.8-4 over the 16-50 f3.5-5.6, the former being a much faster lens. In fact, it is one of the fastest kit lenses I have seen on the market. This $800 saving could be applied toward a 55-200 f3.5-48 lens if you are committed to zoom lens shooting or could go toward a fast XF 35mm f1.4R prime.
Choosing the X-T20 over the X-T2 would mean sacrificing the dedicated ISO dial, the weather proofing, the dual high speed card slots, the three-way articulating LCD and some other items listed in the specifications list below, but this may not be a deal breaker as you also gain a few things. First, it is a smaller and lighter camera, has a built-in flash and its articulating LCD has a touchscreen instead of the three-way LCD.
As a Backup Camera
If you are thinking of a backup camera this might also be a better choice over the X-T2, as you likely have already invested in either X-Pro2 or the X-T2. This smaller camera, provided you are not in inclement weather, gives you an option of a more discreet camera for the street. It also makes an even better companion to the X-Pro2, which does not have an articulating screen, for those over the head or close to ground shots. After all age or mud sometimes makes it impossible to get down low enough to either see the LCD on the X-Pro2 or look through its viewfinder.
As an Upgrade From a DSLR
If you are moving across from a DSLR to the mirrorless world then the X-T2, in most cases, would be a better choice, as this Fujifilm camera is so much smaller than any DSLR on the market. If you are shooting with a lower end DSLR, like the Nikon D5600, the addition cost of this camera buys you an upgrade that has a lot of the features of a D500, and the image quality of the full frame D750 (unless you are shooting at very high ISOs), at a lower price and in a smaller package. So you would not only be moving across but upgrading to a feature rich camera with better image quality.

Like the D750 the X-T2 has a magnesium alloy body, the same autofocus choices, dual high-performance SD slots, however, the Nikon only has 51 focus points compared to the 325. The X-T2 has a three-way tilting LCD compared to the Nikon’s two-way, with it’s small size the LCD is .2mm smaller, which is not really significant. The viewfinder on the Fuji camera, however, has a stunning resolution of 2,360,000 and 100% cover unlike the Nikon. One of the big gains with the Fujifilm camera is the shutter which can be set to complete silence and with a maximum speed of 1/32000 compared to Nikon’s slapping mirror with a top speed of 1/4000. This means when you shoot with the Fuji camera on silence unlike the Nikon camera you hear absolutely nothing.
The lack of a mirror and silent electronic shutter does make for reduce the risk of vibrations when the camera is on the tripod for slower shots, and if you are trying to capture fast moving objects the Fujifilm camera’s 14 frames per second speed is more likely to produce better results than the 6.5 frames per second on the Nikon camera.
Bracketing on the Fujifilm camera is limited to three frames at a maximum increments of two stops, whereas the D750 has up to seven brackets at a maximum of two stops; with the advancements in sensors and high dynamic range processing, this difference may no longer be an important issue, and certainly I have not found this a problem since selling my Nikon equipment.
One of the secrets of shooting mirrorless over DSLR is the viewfinder shows the jpeg! In other words, before you press the shutter, you can see what you will be getting. This allows you to avoid shooting a series of shots before checking the LCD only to find your settings were all wrong. In addition to this, you can correct the jpeg’s exposure and see the adjustment results in the viewfinder prior to taking the shot.
Finally, there is the replacement of a digital read out on the Nikon cameras with real dials, especially on the X-T2 where it has a separate dial for ISO and Speed, with the aperture settings on the lenses. Although this appears at first to be a “retro” look and perhaps cosmetic, it does, in fact, make the camera easier to operate and a pleasure to use. The X-T2 as a result quickly melts into the background as you concentrate on your photography.
