Joe0Bloggs: all this talk about equivalence and nobody even posted the equivalent fl and f-stop for APS, the only valid format for comparison since there are no full frame mirrorless. Apparently multiplying by fractions is too difficult for these guys.

43mm f/1.2 mFT = 58mm f/1.6 APS
150mm f/2.8 mFT = 200mm f/3.73 APS

So what do Sony and Samsung have that is "equivalent" and at what price?

>I know of no technology used for 4/3" cannot be used on APS-C sensors. maybe you do.

As a matter of fact I do, it's called... lenses! lol
Apart from the 43 f/1.2 and 75mm f/2.8, there's also the 12-35mm f/2.8 constant zoom. APS only needs f/3.6 to match f/2.8 but does APS mirrorless even have a f/3.6 constant normal zoom? No... Bet lots of Sony and Samsung shooters are wishing they can screw the 12-35mm f/2.8 on their camera indeed...

It took you a whole day to think up this nonsensical rebuttal?

Let me spell it out for you:
SLRs are not relevant in this debate because their added bulk and weight puts them in another class of buyers.
There are no "equivalent" mirrorless APS lenses that can compete with either of these newly released lenses. The closest to the 43mm f/1.2 is the Sony 50mm f/1.8, and that's too short to be a proper portrait lens on APS and slower to boot.

All anybody has in the ~200mm APS range is a bunch of slow superzooms.

But you knew that didn't you? Otherwise you'd be rebutting with actual lenses rather than this nonsensical drivel.

Thus completely missing the point of my post.

ponyman: Can't help thinking that 24mps is around twice the ideal and hugely detrimental gimmick for a supposedly 'serious' camera.

Of course, I also thought at the time that cranking resolution up to 22mp just so you could get binned 1080p video would be barking mad. Not to mention that 24mp binned 2x2 is still 8mp worth of data (although only 2.6mp worth of resolution), so if you can have a processor that crunches binned output from a 24mp sensor to produce 1080p video, you can also use it to downsample full resolution output from an ‘only‘ 8mp sensor to 1080p video...

Well, I noted several years ago that 2x2 pixel binning on a bayer sensor cuts resolution to 1/9th, so for 1080p video, if you want to bin instead of pixel skip (which massacres low light sensitivity and introduces aliasing artifacts) or downsample from full resolution (which no sane onboard processor would be capable of) you need a minimum of 18mp, or 22mp on a 3:2 sensor for an 18mp crop. Looks like this Sony sensor would be the first generation of sensors at least theoretically capable of this.

LOL! :) Thanks for the info, hope I can get to go see it in person if I visit Sydney. (I used to live there)
