never really used mirrorless. I only have F mount stuff. I would say it depends on your use cases, there are pros and cons with both.
>mirrorlessIf you want something smaller and lighter. If you are hiking much and want to save weigt, and more importantly space, this may be important. I feel that just my D3300 is quite big to have in my hiking backpack for multi day hikes with tent, sleeping bag, cookware, etc. (Then again I'm a lonefag and you have a gf you could split much gear with of that's the case.) But with lenses ML isn't always "that" smaller than DSLRs, lighter though.
Also, if you want to use vintage lenses (not just old, but you know the ones) for fun and not out of necessity a ML is better. All vintage lens guys on YT use them for that reason. (It sounds like you want to use them out of necessity at the moment, but I might be wrong?)
Tying into above, focusing will be easier on MF lenses.
>F mount DSLRIf you don't mind the added size and weight you can get a good used camera for a cheap price. I got a full frame D610 this summer.
Same with lenses, if you want you can buy previous generation's pro gear for next to nothing. The 35-70mm 2.8 D you can find for like 120 bucks. They are often heavier than modern lenses though, which may be a good or bad thing, as they are usually higher mechanical quality (not optically though) than new stuff.
And you can of course get the newer better stuff at a higher price. It's not like the F mount is ancient.
Bear in mind that since your gf have a budget cam, she will not be able to use all the features of the old lenses, many may be locked to manual focus, or if even older be fully manual, with no measurement. If you buy a better model these things will be no problem for you though. However if you get a full frame (FX) her (DX) lenses wont give you full images. There are better DX models too that will work with older lenses.
