I’m a huge fan of the Fujifilm X-Pro2. It combines form and function beautifully and it makes lovely images. The X-Pro2 and the X100F are the two best cameras that I’ve ever owned. What they have in common are the same X-Trans III sensor and processor. Every X-Trans III camera is capable of the exact same image quality, the difference being the design. Form and function varies slightly from model to model, but the wonderful image quality does not. For example, my wife has an X-T20, and the pictures that come out of it look like what comes out of my X-Pro2.
Fujifilm makes a bunch of different models of similar cameras because different forms and functions are important or unimportant to different people. You get the same images no matter the model, the difference is the experience of using the camera. Your choice of camera is about how you prefer to interact with your camera. Of course budget constraints might play a large role, as well. Different models with different features will cost different amounts.
The Fujifilm X-T2 with the great 18-55mm f/2.8-4 kit lens is on sale at Amazon for $1,499, which is a $400 savings. The reason why this camera is currently discounted so much is because Fujifilm recently released the first X-Trans IV camera, the X-T3. The X-T2 and the X-T3 are 95% the same camera, and there is almost no difference in image quality. The main difference between the two models seems to be in auto focus, specifically as it relates to tracking. There is no doubt that the X-T3 is better than the X-T2, but only by a little. There is also no doubt that the X-T2 is a very fine camera.
If you have been considering an X-T2, it’s a good time to buy one simply because it is currently on sale. If it’s still out of your budget despite the discount, I highly recommend the X-T20, which is not all that much different than the X-T2. My wife loves hers! She’s become a Fujifilm fan quite quickly after I got her an X-T20 for her birthday. It’s also on sale right now (with the 18-55mm lens) for $1,049, which is a $150 discount.
