Decide on your budget, add some more (for all of the things you will think you will need after you get a camera -- in-spite of whether you actually need them or not 😀).
Once you do that, take a look here:
One of these will catch your eye. Ditto for the lenses. Check your local camera shop to see if they have some in stock. The various online sellers often have sales on the gear. Once you get a little closer, check back to make sure things are not too far off the mark, so to speak.
Are you using the XC 15-45mm kits lens?
That may be what is giving you some troubles, that one is not Fujifilm’s fastest focusing lens. It does have some low light issues while the body does fine when you put a faster focusing lens on it. Which lens to use depends on your budget and which focal range (how you intend to use it) you want. The XF 16-50mm is a constant f2.8, the 35mm f1.4 or 23mm f1.4 are well regarded for low light settings. The XF 18-55mm does fine work, but is not as fast as the others I mentioned.
Stopping down means setting a higher number f stop on the lens (or use the body to control the lens — you turn this on using the menu settings).
Want to invest in a 'real' camera rather than using my google phone for street photography and sometimes landscape. Looking at Canon but really being drawn to Fujifilm after many hours of 'YouTubing'. Mostly edit my images to monochrome. Would like to have a choice lenses and manual settings. Any recommendations most welcomed
