Hi guys..! Thanks for your valuables replies..
I have been thinking about the following lenses (I wanted fast 35 & 50 or 55mm lenses)
Canon FL 55mm f/1.2 around 279.99USD
Zeiss Planar T* 35mm f/2.0 around 152.99USD
both on Ebay. What do you think guys? I tried to find FD lenses , and found a nFD 50mm f/1.4...should I stick with the 55mm FL 1.2 or the 50mm nFD 1.4? the f/1.4 is around 129.99
All these are high prices. Look at keh.com to see 15% more than you should pay. I bought a good user FL 50 1.2 from keh last fall for 165USD.
the nFD lenses are usually much lighter. You can check the weights here:

there is a difference between FD lenses and nFD?
Also found several Nikon 50mm f/1.2 lenses but almost twice or triple the price of the Canon lenses...but there's a lot of them around 300-500USD so there's not so much problem getting one, while getting a good canon it's almost a race..there's a bunch of Rokkor, Minolta, etc etc etc 50mm f/1.4 lenses. It's that much the difference between 1.4 and 1.2 apertures? by this you can guess my approach of taking pictures with available light, without using flash.
A good 1.4 will work in low light, but 1.2 is better--however DOF gets really tight. This gives you more creative options. Many of the 1.4 lenses are sharper than the 1.2s at F4---but this great depends on the model.
Just remember you are talking about 75mm EFL NOT a normal lens---a portrait lens.
A good 35 is much more flexible on the nex--I think a 28 is even better. Sigma makes a 30mm f/1.4 which is pretty good in several mounts. They are pricey though at around 350--but I could be wrong.
the CV nokton 40/1.4 is a good lens and VERY small, CF at .7 meter I think, and they can be found used for a bit over 300.
Be patient and study up while you watch auctions. Bid late, so your options are open. Watch FM, DPI, RFF and any other good forum marketplaces.
Check completed listings on ebay to see the good prices.
Every day you see overpriced lenses, just ignore them.
here's a cute 50 and only 129 grams:
