Perhaps there is another 25mm f/1.4 besides the Panasonic lens, but the price of that 50/2.8 full frame equivalent is considerably more (~$200) than either Nikon or Canon's 50/1.4s.

What about the price of the cameras you mount those lenses on?

What does the price of a full frame body have to do with you posting incorrectly that a two-stop slower 25mm f/1.4 m4/3 lens is cheaper than a full frame 50mm f/1.4?

Wrong. What I said what that you have to pay, in size and price, to shoot f/1.4 on FF. A lens doesn't take a picture by itself. Shooting FF costs more money, period.

If size is also an issue, you can still retain over a stop advantage with full frame by buying an ultra cheap, small, and sharp 50mm f/1.8 from either brand.

What about the size of the cameras you mount those lenses on?

What does that have to do with the fact that your 25mm f/1.4 is heavier and considerably longer than the 1 1/3 stop faster Canon 50mm f/1.8 (and close to 6X the price)?

Again, it has to do with the fact that a lens doesn't take a picture by itself. You need a dinosaur camera that costs an ungodly amount of money compared to MFT cameras.

If you always shoot so close up that the depth of field at f/1.4 on full frame is too shallow, then the cheapest option would be a Nikon APS-C DSLR with the $200 35mm f/1.8 (52.5mm f/2.7 equivalent).

F/1.4 on FF is too shallow for most types of photography regardless of how far away you are focusing. MFT as a complete system with lens options blows out Canikon APSC pretty badly.

If I double the distance to subject that you are using with your 25mm f/1.4 when using a 50mm f/1.4 on full frame, we'd have the same depth of field. Do you ever take a photo of the same subject from different distances using the same lens? f/1.4 on m4/3 is always the shallowest depth of field you could want regardless of distance?

Did I say it's always the shallowest depth of field you could want? If you want something that will always give you everything you want every single time, Earth is probably not the planet for you.
