If you are on a limited budget, then you want to be able to buy and use second hand lenses – for normal canon or Nikon SLR there are LOADS out there at very reasonable prices
Not so for the mirrorless cameras.
You sure about that?

Lens Adapters
Because they’re small in size and lightweight, all of these manual-focus M-Mount and M42-Mount lenses make great companions for today’s compact mirrorless digital cameras such as the Micro Four Thirds cameras made by Olympus and Panasonic, the Samsung NX200, Sony NEX cameras and the Ricoh GXR. After all, attaching a 5-pound lens to a 1-pound camera defeats the purpose of having such a lightweight camera in the first place.
All you need to attach an M-Mount or M42-Mount lens to a mirrorless camera is the right adapter. Because the lenses are fully manual, including focus, you will have to shoot in manual mode, regardless of any modern features the cameras might offer. The exception, of course, is that you can expect full functionality when you use a modern Leica lens on a Leica Digital M camera. And remember that you can use any M-Mount or M42-Mount lens with these adapters, regardless of whether they were made in the 1950s or this year.
B&H carries hundreds of lens adapters, but here we’re concerned only with adapters that will allow M-Mount and M42-mount lenses to work with mirrorless cameras. If you want to adapt an M-Mount lens to a Micro Four Thirds camera you have three choices of adapters: there’s the Novoflex Leica M Lens to Micro Four-Thirds Camera Body Adapter, the Voigtlander Micro Four Thirds to M Lens Mount Adapter and the Dot Line Micro 4/3 Mount for Leica M Bayonet Lens. If you want to mount an M42 lens on a Micro Four Thirds camera, the Novoflex M42 to Micro Four Thirds Lens Adapter will do the trick.
