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.

For equivalent shots, it tends to cost less if you like lens speed, and in some cases, the comparison isn't even possible (got any f/1.4 zooms for 4/3?).

"Shoot f/1.4 on FF" should be pretty self-explanatory, it doesn't mean shoot f/2.8 on FF. For equivalent shots, you are forgeiting FF's advantage in IQ because you have to shoot at two stops higher ISO to get the same exposure, and it still costs more because of the huge price difference between camera bodies. Especially if you compare high end to high end or low end to low end.

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.

A 6D and a GH4 cost the same. And a 6D is a fine camera with a far-superior viewfinder and supporting lens and accessory system.

Oh I see, you're comparing the most tricked out, highest-specced, state of the art MFT camera that is really more specialized in video, to the most bare-bones, stripped down, entry-level FF camera with only one card slot. Yeah that's a really fair comparison. Calling the viewfinder far superior is like calling black and white photography far superior to color - an entirely subjective statement of opinion that is becoming more of an anachronism with each passing year.
