Hello Edmond,
If you start photography, XT serie is a good choice. I got Canon, Nikon, Olympus before and when I switched to Fuji, I decided to stay with for multiple reasons. First, the sensor has a different technology than the classic one from Canon or Nikon. It gives less noise on high ISO. Secondly, they are not so heavy as Nikon.
I first started one year ago with an XT-10 and fall in love with it, due to the quality of the pictures. It is relativelly cheap in comparaison with the possibilities it offers and you might find good bundles with the XF 18-55 or XF 18-135. The XT-10 and now the XT-20 offers also what I will call a "rescue mode" with full automation, as you can find on pocket cams (panorama, portrait, sunset etc..). This is usefull if someone of your family or friends want to take a picture without being photograph.
The XT-2 is a good choice for a more long term, as I bought one recently. It has more professional functions (better positionned function buttons, ISO quickly accessible etc.) and is waterproof which is not the case of the XT-10.
The specificities of the XT family are multiple:
Specificitiy of Fujifilm X and XT cameras is the direct processing of the RAW to produce a JPG ready to use. If you always work your RAW with Lightroom or PhotoShop, you don't need an XT, but if you want to shoot compositions ready to print or to publish, your are right. Personally, I try to avoid any post-processing of my pictures so the XT is my best choice. Because it is an hybrid, you can see the approximated result of your picture before shooting. If it will be underexposed, you see it in the view finder. Quick menus to access your predefined settings. You can switch from Vivid colours to B&W in 2 seconds, just push one button, rotate the dial to the pre-selected settings (White balance, ISO, Dynamic range, Sharpen/Soften, Colour/B&W, B&W with Y/G/R filter...) The number of parameters that define the shooting (processing of the RAW) and the Exposure/Autofocus is high. You will need some time and a lot of trying to play and understand how these parameters change the resulting picture.
My daughter, who is 17 years old, started photography one year ago and she bought last month it's first XT-10 which is a used one but still working well. She knows now how to play between ISO, Aperture and Speed and she achieves very good results (I think that she is more artistic than me as she finds better composition )
Please be advised that some Fujifilm cameras experienced quality problem. You will find more about it in other forums. Some XT encounter failures. During summer, my daughter's XT-10 losts all parameters (like factory reset). When I went to the shop, I wansn't enable to reproduce it and it worked fine again. My XT-10 makes the same one month later despite having allways a charged battery in it, and I couldn't reproduce the problem later on.Testing a new 100-400, the XT-10 starts to bug, despite the firmware upgrade. The only good point is that the waranty is working well and the time to repair is short.
To be honest, I didn't search on the Internet if other brands have also quality issues. Maybe all cameras might have problems
To conclude, and despite the fact that some Fujifilm cameras encounters quality problem, I will stay with this brand. The XF lens are very good and at the end all the equipment will be less costly compared to other brands.
I hope it will help you to make your choice. You can have a look to pictures of my daughter and myself on Instagram davidh_photography and celesteh_photography.
Cheers,
David
