Well, it IS twice as fast and there really is no plausible other way of looking at it 🙂
However, if you'd say it doesn't necessarily suit everyone's needs, I'd agree… for my part I'm just happy it suits mine!

Well, by my calculation, f/1.2 is a bit more than twice as fast as f/1.8 (though the discrepancy is minor). I'd say that "twice as fast as f/1.8" would be f/1.27. Or, "half as fast as f/1.2" would be f/1.7.

don't forget that dynamic range takes a hit as iso goes up.
this lens is yet another reason for me to skip ff dslrs entirely. 🙂

(That's assuming that the new f/1.2 lens really is 1.2, not say 1.25 or 1.27.)

I believe he is referring to depth of field equivalent, not lens speed .
One needs about one stop faster with small sensor .

@f16sunshine: I am willing to bet the focus accuracy is great. From my understanding of the way contrast detection system is designed, the lens stops down and contrast detection occurs on chip at the point of focus. This has inherent advantages vs. the classic DSLR style of focus which always focus wide open and not at the chip level.
This would also take into account any focus shift that maybe present when stopping down because you are assessing focus on the chip itself. I think this also helps when choosing on off center focus point because if the field is not perfectly flat (most lens are not wide open), then using a off center contrast detection focus point should improve off center sharpness.
I guess the tradoff is speed, but Olympus and Fuji have shown marked improvement in speed.

Looks great, and maybe some 60's will show up on the used market at good prices. I'd rather have the 60 for the macro capabilities, but if I had a big enough sack o' money, I'd get both.

I don't use any of the lens hoods on any of my fujis. None of them really need them. The 35 is the most susceptible to flare, but is still pretty difficult to make flare.

really, none and never?
do you use filters for protection?
i need to try that maybe...

BW clear filters on all of them.
The 23mm is more or less unflare-able, the 35 isn't bad but I actually like it when it does flare (e.g. - I'm usually trying to induce flare when it does flare). The 18mm hood is so small I just keep it on.
The way I see it, Im using the camera because it is small and unobtrusive. Why put these giant petal hoods (23mm especially) on it and ruin the size?
I did the same when I used the canon FF system mind you.

If I don't like an OEM hood, I just buy a couple on-line that look promising. I test them to make sure there's no obvious vignetting.
The Fuji lens coating work well so the hood is just for front element protection.
Except for scenes with strong glare, I never use screw-in filters.
For shots where a bright sky and shadows from building structures exceed my cameras' analog dynamic range, I use a 4" X 6", 3X, soft, nuetral gradient filter. I position the filter by hand (the camera is on a tripod of course) to reduce the sky brightness. This is a very expensive filter, but it solves a serious problem for me.

it's either snowin' & blowin' around round here or just blowin' (prairie winds) so i almost always use both a filter for protection and a hood!

BA, front lens elements are pretty durable these days... I never use filters for protection... or hoods.

Some are some aren't. I use protection filters as I'm often near salt water or drinking folk.
I have to admit that the filters have effected my images at times in negative ways.
For portrait shoots or in controlled environs I remove them.
For hoods I agree that the fujis don't really need much.
The x100 now has a tiny little Pentax shade on it and the X series lenses I skip the hood altogether.

^^^I have the same hood as well as the JJC replica. I'd like to get my hands on the authentic Pentax silver version, but I'm happy with what I have.

i've looked for the copy version on ebay but couldn't find it!
i have the jjc black version of the fuji hood and like the look of it.

I was very lucky and found a US retailer on eBay selling it for $17 shipped, brand new in box. I don't see very many for sale, even from international sellers.
But if you're interested in a JJC/RainbowImaging black copy:
