    Just see this on MFT Rumor. Both Lenses has come with Black or silver, the 21mm 1.4 is $499, and the 50mm 1.2 is $549, it can be pre-order from B&H.

    I like the quality of Rokinon 7mm fish lens, but these new primes also made for APS-C too, it looks big.

    Not so much for the 50/1.2: it is smaller and lighter then the PL 42.5/1.2 (74 x 77 mm - 425 gr - 67 filter thread).

    I may be able to see the usefulness of the 50mm, but the 21mm? Nope. It's a MF lens, and only 1/2 stop faster than the 20mm f/1.7 from Panasonic, which is a pancake lens, an capable of AF, AND is much cheaper.

    What's odd is that it doesn't appear to be designed purely for an APS-C sensor either, since 21mm would yield a 31.5mm FoV, not 35mm. Strange...

    On the other hand, I don't really see the usefulness of the 50mm -- it's not like there's a shortage of 50mm manual focus lenses we can use and most of those are much cheaper.

    crop factor for canon apsc is x1.6, so that gets it to 33.6mm which is pretty close to traditional 35mm

    I tend to agree with all of the above. The 21mm/1.4 has very few advantages over the 20mm/1.7 - a 1/2 stop and a load of compromises for twice the price.

    The 50mm/1.2 also ends up being more expensive than a lot of legacy 50/1.2s - though it may be optically better at this point. But you can also just get a cheap 85mm/1.8 and a focal reducer. Or a Samyang 85/1.4 and a focal reducer to give you a 60mm/f1 for $150 less.

    I have a Pentax 50mm f1.7 that becomes 100mm with the crop factor and it works a treat. So I gain an extra half stop with this lens? My Pentax with the adaptor cost 10x less and is also manual focus.

    It's an extra full stop from f1.7 to f1.2.

    Legacy f1.2 lenses are in the $250-500 range.

    Extra full stop, my bad. But f1.7, f1.8 does me fine.

    That's always been the case with photography, though. A constant f4 zoom will cost 3x as much as a f3.5-5.6 zoom (which is good enough for most), and a constant f2.8 zoom will cost 2x as much as the f4 lens. Diminishing returns cost exponentially more to achieve.

    I would say a minor correction to the title. These are Lenses for APS-C that happen to also have been made available in MFT mount. That has major implications on their size (and likely cost).

    And honestly all of them kinda suck until about f1.8-2 anyway. Major glow and softness at f1.2 that you would not tolerate on a modern lens.

    If that can even come close to a brand new native f1.2 lens alone, then the designers have failed miserably.

    I agree that I probably wouldn't use the legacy lenses at f1.2. But the focal reducer typically improves lens performance. Stop the 85/f1.4 down to f1.8-f2 and you'll likely be doing better.

    ...and then you've got an 85/1.4 for when you want that, also.

    And it's bigger than a 35-100 and twice as heavy! :)

    I agree in theory that a focal reducer can improve quality, but probably not if you are going bargain hunting.

    I'm just glad we're seeing some mirrorless specific designs like the 12/2. Sure, these lenses are a little bigger because they cover an APS-C image circle, but at least they're not APS-C or FF DSLR lenses which would be much bigger due to the increased flange distance. The Samyang 50/1.4 for instance is 535g, and that is without the necessary adapter, which results in a length of 106mm. The 50/1.2 is about half the size and weight of it's slower 1.4 FF DSLR counterpart. The Samyang 24/1.4 is a whopping 680g, again without adapter.

    The Samyang 85/1.4 is 520g, plus a speedbooster (170g) is 690g, or about 2.5x times the weight of this 50/1.2. While it's a relatively inexpensive lens (~$300), you have to pay $200-500 for the speedbooster, so you're not saving any money unless you have a collection of legacy lenses to use with it.

    Additionally, these lenses will likely be extremely good optically, almost certainly noticeably better than 30 year old legacy lenses. Samyang lenses tend to perform very well. Most legacy 1.2 lenses tend to be best described as "dreamy" (read: very soft) wide open. Which is cool if that's what you're after, but probably not what everyone is looking for. Street prices for Samyang lenses tend to be quite reasonable too if you can wait 6 months or so after release.

    I can see the appeal of the 21/1.4, especially for video guys who prefer MF lenses, there are exceptionally few legacy/mf lenses this wide/fast and the ones that are (in the 24mm range) are much, much bigger, and/or insanely expensive like the ~$7000 Leica 21mm 1.4. I guess you could use a legacy 28/2 on a speed booster, but again that combo will likely be bigger/heavier and not cost much less.

    That said, I won't be swapping my 25/1.4 or 42.5/1.2 for either of these, because I prefer AF. It would be great to see more lenses designed specifically for M43rds as well, but when you consider economies of scale, it makes a lot more sense for Samyang to design a lens that can be used on all the mirrorless systems like these and the 12/2 rather than simply M43rds.

    These honestly seem to make the most sense for Canon EF-M mount. 34mm equivalent f1.4 and 80mm f1.2? There's pretty much your classic 35/85 prime duo. Sony users will probably appreciate another fast option in the EFL 35mm-ish range, given the CZ 24mm f1.8 is ridiculously priced. They don't really have many options faster than f1.8 at any price for that mount, either. Fujifilm already has an outstanding 23mm f1.4 and 56mm f1.2, and I guess these are a little cheaper. But I'd still bet most would rather buy used copies of those lenses.

    For us, there appears to be zero advantage to the 21mm f1.4 over the 25mm f1.4. We had a 25mm 0.95 just launched from Mitakon. For the 50mm f1.2, we have quite a few manual 40-50mm options in the f0.95-1.2 range.

    I'm going to shut up now, though, because I like that Samyang is making their designs available in m4/3 mount. More options are better, even if they aren't for me today.

    Fair enough. I've got a Rokkor 50mm f1.4, which I see is currently sold on ebay for only about $70. However, like you say, at 1.4 it is awfully soft.

    Looks like they're making cine versions of both lenses as well. I'll prolly pick up the 50mm once street prices drop a bit hopefully sometime next Spring.
