    Those with fast fifties weigh in. Is my lust for a 1.2 lens irrational. I have a bunch of great 1.4 fifties. Right now I am jonesin' for a Canon FL 55mm 1.2. I wish I could spring for the 58mm Rokkor 1.2 but they are crazy money. What say the experts?

    I have a high serial number Oly Zuiko 50 1.4 and given the performance at 1.4 I have zero interest in an f1.2 lens in this vintage. It is significantly softer than the PF25 at f1.4. Most of the 1.2 images I have seen are softer than the Oly 1.4. IMO they are simply not worth the price of admission. Here is an example of the 50 1.4 and the 12-60 @50. The 50 prime is at f2 or f2.8 sorry I can't remember and I did not write it down. The 12-60 is at roughly f4 and I think it is the better image:

    only got one 50/1.2.....a Nikkor oh and the ocassional use of the girlfriends 1.0 Noctilux,

    the nikkor (along with the OM 50/1.4) definately go a bit 'dreamy' wide open, plus contrast seems to go a bit off, though PP will bring that back

    At the end of the day 1.2 is only a half stop from 1.4.... and harder to focus

    suppose in the end its down to what you are looking for... light gathering or shallow DOF?

    Which does turn the low cost 50mm 1.8D into a 35mm f/1.2 lens. Otherwise my 50mm f/1.2 turns into a 35mm f/0.9, which is scary and offensive to many photographers of all systems for some reason.

    And let me tell you, that 50mm f/1.2 is stupidly sharp even if you leave it at somewhere between f/1.8-f/2.0 on the lens side (Effectively f/1.2 after the Speedbooster)

    I would recommend against the 1.8D for manual focusing, get a nice AI/-S or a 50mm f/1.4D, the focusing ring has some mild resistance to it instead of the plastic-on-plastic feel. Not that you can't, it just won't be as nice.

    It isn't irrational when a significant fraction of his keeper images start closing towards half second exposures at ISO1600 and up.

    Option 2: Get a Sigma 18-35mm f/1.8 and Speedboost that into a f/1.2 zoom. I am already planning that for my own future lens purchase options before I get more m43 optics beyond my 14-42X.

    You are speaking to a guy that had 29 guitars until recently. I've paired it down to 22 now :) See I'm getting a handle on my GAS.

    The OP states that he already has several f/1.4s. An f/1.2 lens is only 1/2 stop faster than f/1.4. That would be a totally insignificant improvement in low light capability.

    IMHO, it is a totally irrational urge on the part of the OP. Still, it may be an urge that he should attempt to satisfy.

    For handholding:
    My Speedboosted 50mm f/1.2 can get me handheld shots at 1/2s exposures that are blur free with a near 100% rate if I am relaxed and braced with the E-M5's IBIS. At 1s and standing, that rate plummets like a brick. Between 1/1.3 and 1/1.6 I would hesitate to take a shot and crank up sensor ISO to keep shutter speed around a half second. A half stop of lens when you are at infinity focus is significant enough if you constantly push your self and your gear to take the shots that matter.

    Not a good example as 1/2sec to 1sec is a full stop; twice the 1/2 stop "improvement" of going from f/1.4 to f/1.2.

    The FL 55 is a beautiful lens. The build-quality is second to none anywhere, the focus-feel is smooth and professional allowing for very precise adjustments, and the lens highlights are unique and gorgeous. It's one of the cheaper f/1.2 lenses available and a joy to shoot with.

    I can't speak to whether or not somebody with a bunch of f/1.4's should get an f/1.2 because I don't understand how the two topics relate. I have lots of lenses that are close in focal length and I love them each for their own unique characteristics, not because I need a certain focal length to be represented by a single lens. If you like how the lens renders or feel a need for the extra half-stop of light, then I say go for it. You just might find a lens that you love. If not, it holds its value at the same level that you bought it for.

    FYI there's currently a Canon 50mm f1.2 (new FD mount) being offered in the Buy/Sell forum for a fair price:

    https://www.mu-43.com/showthread.php?t=55518

    If I hadn't recently laid out $430 for the Panaleica 25mm f1.4 and $190 for a Samyang (actually branded Bell & Howell) 85mm f1.4, I might have bought this lens myself.

    If you buy such a lens for how it renders at wide open... yes.

    If you buy such a lens for that 1/2 stop... no. There are so many advantages to a modern digital camera's ability to push ISO 1/2 to 1 stop over the many disadvantages to such a lens (size, weight, slow focus, shallow DOF).

    Exactly. I am not wild about how the Zuiko 50 1.4 renders wide open. It is a little soft for my tastes.

    I know the Nikon is soft wide open which I really like using for portrait. Will test out the Canon tomorrow as the brown truck just dropped it off earlier.

    Its a good example of where a small, sub-full-step advantage actually matters when your exposures are pushing the ISO setting to the point you know you're going to lose more detail to noise than having the lens wide open.

    If you think the 50/1.4 is soft, you should try the OM 55/1.2 or some of the other 1.2s. They're 'fun' lenses at wide aperture, but sharp they surely are not!
