TBO this situation is so ridiculously insane it might as well be.

Send this to Jensen every time he claims that frame generation is real performance.

Edit: typo

My, my, you are asking a big question herehere are some to start out.

• Carl Zeiss Jena Tessar 50/2.8 (Soap bubble bokeh and three element goodness.)
• Auto Chinon 55/1.7 (beautiful, smooth and perfect bokeh You have never seen anything like it. They are quite rare, however.)
• Meyer Optik Görlitz Primoplan 50/1.9 (Beautiful micro contrast and very smooth gradations. Brilliant black and white lens.)
• Meyer Optik Görlitz Primotar 50/3.5 ( four element goodness. So, essentially, most of the organic qualities of the Jena Tessar, but with the more organic components toned down. Microcontrast suffers a wee bit under the additional element, but not too much.)
• Meyer Optik Görlitz Telemegor 180/5.5 (The long telephoto portrait lens. Enough said.)
• Super-Takumar 135/3.5 ( If you check online and find this lens for maybe 30 to 50 quid, you’ll think you’re insane and you made a mistake and you accidentally bought a way more expensive lens. The micro contrast and resolution of this lens is unreal, especially considering the price.)
• Nikkor 28-85 mm f/3.5-4.5 AF ( You can buy them dirt cheap for less than 100 quid online, and it is a good competent zoom. It even has a macro switch, so if you’re just starting out and want to spend little money, this lens is your go-to.)

All of these lenses should be readily available on eBay. I excluded the rare stuff.

Edit: And there’s much more. I still have a very limited experience with that. I have some more than I outlined. But believe me, there’s some great stuff out there waiting to be discovered. I also fixed a spelling mistake

Spend as much as you can on the lens. The camera is negligable. Listen to someone who made the horrible mistake of inverting that philosophy once.

Adapting with lens/camera communication usually does not work. There are some bayonets which can do it, but they are very, very limited.

Forget adapting anything to a DSLR. In all honesty, you really should buy mirrorless cameras. Reason being mirrorless cameras have adapters to basically every bayonet ever created. DSLRs do not. With DSLRs you are locked into the manufacturer of your DSLR for your lens choice, which may be very limiting.

Also, try to adapt manual focus lenses to your camera. Many of mankind’s greatest glass is manual focus only. Bonus is you can get a manual focus lens for dirt cheap, one that has quality that will blow your socks off. People think that old optics are inherently worse, which is false. Optics haven’t had any development since a hundred years, with a few minor exceptions.
