You are looking for something that does not exist.
The mirrorless camera with the most lens options is probably the Canon M series.
If you also use their EF EOS M adapter, you can use any of their EOS DSLR camera lenses with all lens functions available. They have the biggest stable of DSLR lenses around.
Since Lenses play a very important part in image quality, and I heard kit lenses are not considered good.
So, I want to buy an APS Mirrorless Camera for which I can get good quality lenses also on less price.
My purpose is : Traveling, Portrait - family photos
Mainly interested in Zoom Lenses with high aperture eg :
15mm F2.1 to 45mm F3.5 + 45mm F2.1 to 200mm F3.5,
15mm F2.1 to 150mm F3.5 + 45mm F2.1 to 200mm F3.5,
Prefer high aperture eg : F1.7, F1.7, F2.0
Also, very important factor Image stabilization and Autofocus should work with the body / it should be compatible, no adapter should requir.
I selected some of APS-C Mirrorless body :
Fujifilm X-A5, Fujifilm X-E3, Fujifilm X100F
Sony Alpha a6500, Sony Alpha a6300
Canon EOS M100, Canon EOS M6
But when I am checking online to buy lenses for these cameras (eg on amazon, bhphotovideo, bestbuy), I saw very few options and that also at very high price eg $300 to $800
I also check on lenshero.com but same very few options with a very high price almost same as what I am investing in a camera body only.
Please suggest me APS Mirrorless camera body which has fast lenses option on less price, include IS and AF Compatibility with no adaptors require on it.
