9VIII: Mirrorless cameras now have a reason to exist.
APS-C is cheap compared to full frame, but gives up clarity and light from the smaller sensor. If Canon were to put one of these on a EOS-M that doesn't suck, people would have legitimate reason to chose EOS-M over an equivalent SLR.

Let's not push it... the M isn't exactly the best of the mirrorless, if one would trust the reviews. ;)

plastique2: It is really about time to change the term used in the English speaking photography community for the capability of a lense to let through more or less light. The term "speed" is absolutely misleading. We from non-english speaking countries have to endure the torture of reading photography related material translated from English by people who have no clue about photography.

This can look like this (my attempt to make an impression of what we actually have to read in our language - because someone translated literally something he didn't understand what it's about - but then who can blame them given the English text):

"This lens is very fast, although it isn't fast at all."

When we say in our language that a lens is fast, it always relates to it's ability to perform any kind of mechanical operation in a short time period. Yet when we wan't to address it's quality of light gathering, we use two words, the translation would be: "light power". Doesn't that make more sense?!

Totally agree with you, and BTW it doesn't really make any more sense in the English language either! Another term often used is "bright" lens, and that is what should be used all the time (especially on photography websites catering to an audience of varying levels of experience). Just because a bright lens allows you to use faster shutter speeds isn't a good reason to call it a fast lens IMO.

davidbindle: So if the adapter was used on a traditional slr APS sized sensor - would the AF performance improve?
I have both a 5DMKII and a 60D. At times, I only want to bring one camera and that could often be the 60D especially if I want more reach from my 70-200 2.8. But if I could get 25.6mm at the wide end of my 24-70 2.8 (and at f2.0) that would be pretty cool!

I wonder if they even could make a pure Canon FF to Canon APS adapter. Perhaps this is an impossibility because they can only work with mirrorless cameras??

Just wondering

they mention in the article that AF performance decreases

Timmbits: Forgive me for saying this, but the purple fringing, chromatic aberration, is much worse than the text suggests (which uses words like "impressive") and reading "You'd be hard-pressed to find significant difference between the two files in the center of the image"... well I beg to differ! Even at center, one image has black, while the other has CA even at center, because there is no black: everything's purple!
At this price point, we have the right to have certain expectations.

@Viking: that is exactly my point: an APSC camera will set you back a thousand bucks, give or take, and the cheapest FF is what, about $2k for a D600? I'd much rather get the FF.
But staying on the apsc topic, I buy used legacy lenses on ebay (have a nice Minolta 50mm f1.4) that cost me $100, and the adapter $20 (no optics, just physical adapter). I'm now on the lookout for a nice ~30mm f1.4 as I own the samsung 30mm f2 but want to do better.
Now the $600 question: how many lenses, used, can I buy, for the price of this optical reducer that gives me mediocre image non-quality?
I just think it is a rip-off.
How long will it be, before the chinese are selling adapters like this, for the same price they sell their 2. and x0.45 adapters? (which is around $50) ...and judging by the image quality of this one, it won't be hard to match.

Just saying.

Richard Murdey: 1:1.8-2.7

Wow. That's all you need to know, right there.

@artashes: don't forget that a "26mm equivalent" lens of a 1/2.3" camera is smaller than a 26mm equivalent lens of a 1/1.7" camera. thus the f1.8 opening is smaller too. do the math. it is not as bright as the current f1.8 - 1/1.7" lot - it's closer to the brightness of a f2.4 on a 1/1.7"

Timmbits: Don't let the f1.8 number fool you! For all you guys who think that f1.8 is a big deal with a 1/2.3" sensor, it is equivalent to only f6.4 on an aps-c sensor camera.

According to the link below, you would need a f0.5 on a 1/2,3" sensor like this one in order to compete with an f1.8 on an aps-c sensor.

And we're not even comparing to FF (which is the more common reference).

Here is a very useful link for everyone in this forum:
http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm

Anyways, I realize that this is a high-end in the low-end cameras, and these comparisons aren't really relevant to it't target consumer market.

Just putting things into proper perspective here, so we can all understand what we are looking at.

@TOMEK: you are way out of your depth!
on a APSC, you could have f6 as an equivalent to the f1.8 on a 1/2.3" sensor! And you could use a much much faster shutter speed on the APSC at f3.5 than on this one at f1.8.

You guys don't get it do you?
FIRST, if you were even able to understand the link I sent, you would see that it allows you to also compare with a 1/17"!
SECOND (@PaulRivers) pretty much ALL the current enthusiast compacts have a better lens than this (because with a 1/1.7" the lenses are larger, thus their f2 or f1.8 opening is larger), so there really is no currently produced compact enthusiast with a worse lens.
THIRD:@all It's not just about DOF! Also relative brightness! ie: light gathering area of the sensor, coupled with the opening (this smaller lens divided by 1.8 in this case).
FOURTH: @some of you (you know who you are), you are making EXACTLY the same mistake you made when you bought your Q10: drooling over something smaller and cheaper thinking it's better.
...AND FINALLY it was just an FYI so that neophytes who are reading your myopic comments can get some TRUE FACTS and and get a better understanding of the compromises versus, say, an LX7 for example.

GeraldW: Hey Timm, lighten up. There are a few 1/2.3" sensor cameras around that do quite well up to ISO 800, and with the fast lens, that will seldom be needed. What cameras? Panasonic FZ150, FZ200, and ZS15, Canon SX230HS, SD4000IS, Pentax Q.

The Sony RX100 as a competitor isn't valid, as the street price in the USA will be 2:1. It won't sell unless it's under $300. The Canon S110 is valid as a competitor, and Olympus would seem to have chosen a faster lens to offset the larger sensor; but slower lens, of the S110. At full zoom, the XZ10 has a 2 stop advantage.

As far as DOF control, I think it's funny that what was considered a drawback 50 years ago is now touted as a feature. I started as a serious hobbyist in 1955, and somewhere along the way, "selective focus" became a new way to compose. For many situations, a large DOF is an advantage.

This camera is obviously not for you, and maybe not for me (I have an S90 and a G15); but I can see a number of valid uses for it.

Kirppu: Crew of photo enthusiast grouping together to pitch about P&S camera for not having big enough sensor. :D
This just a little brother of XZ-2 which is also an P&S camera. You know they sell these for the masses in the markets and online shops. By next quarter this will probably be 100 pucks cheaper. People who are looking for IQ and shallow DOF should not even bother comment this camera...
And who here all ready know how good P&S IQ this cam has?

the thing is, 1/2.3" sensor cameras go for $150 these days. it's gotten old a long time ago. and we are disappointed that manufacturers take us for fools when they try to put a marketing spin on something obsolete that just doesn't cut it anymore.

when labeling something "enthusiast compact" with RAW capabilities, it sort of sets the bar in terms of expectations.

g7star: Everyone's basically saying Olympus needs Sony sensor(or tight body), and Sony needs Olympus lens. Hopefully they come out with one sometime soon.

Just to dispell any misconceptions, the RX100 is an f1.8 on the wide end, and f4.9 on tele.

rallyfan: Argh, the "blurry background" lot are at it again.

If you don't have astigmatism yet desperately feel your backgrounds simply must look as if you do, what can I say other than go buy another camera.

A blurry background won't save your images. I doubt anything can.

Then there's the "wider lens, nobody uses 100mm+" crowd. My only hope is that you stay out of the photographers' way as you try to get oh-so-closer with your wide angle lenses...

TROLL

mpgxsvcd: This camera would be interesting if Panasonic hadn't been dumping their LX7s for $279 lately. It is just like when your neighbor dumps his house for half of what it is worth and now no one else can sell theirs.

I have seen websites that promise an item at a price but then do not deliver... or they have sales reps that are supposed to upsell you, or tell you there is no more stock if you don't order high margin add-ons. there are even phishing websites out there that come up in searches, promising a certain price, but have no inventory.... and you only find out after you created an account with them and left information...
So that is why I was asking... is there a legitimate site selling these at this price point? btw, I doubt they can make it for less in turkey than in china (which isn't a reference either btw).

Camp Freddy: Hmm, after a quick look at this and the price suggested, I think Olympus would have been better on doing an "epm" version of the larger XZ's to this type of price, or better yet, putting a fixed retracting lens onto the 16mpx mFT sensor, perhaps at a crop to a smaller mpx ( as some panasonic mFT's actually do)

@MANUEL: either you misunderstood me, or I am a poor communicator... regardless, I was only expanding on what you were saying. I was trying to explain WHY the rx100 has certain design limitations (which come from a 1" sensor in such a small package) - like f4.9 at tele, and these design decisions would have to be even stricter if we thought of putting an even larger sensor into such a small package, hence why they couldn't hope to put an mft into the rx100's size.
AND... I was also trying to say, that it WOULD be nice if there WAS a fixed lens MFT camera, to oust the impertinent Nikon-1 out of it's space... An aps-c would be a bit too large for us to wish for that... but an MFT might be a feasible possibility.
But again, this is beyond the scope of the discussion under the xz10. ;)

SunnyFlorida: 1/2.3" sensor?...Pass, I'd rather buy a used XZ-1

indeed, I had an XZ1, and the low light performance was dismal... at least to me who had a P7000 right before that.

Timmbits: with a tiny 1/2.3"sensor, this might be good for my 7 y.o. child, to introduce her to photography...
but surely anyone in their right mind wouldn't consider this over ANY of the already small 1/1.7" sensor cameras.
I really don't see the point of the existence of this camera, if not for kids.

@marike, in case you haven't yet noticed, 1/1.7" is already too small! it isn't exactly a reference or a standard to aspire to! comon, WAKE UP!

Timmbits: Maybe it's just for the ignorant mass-market... they can see f1.8 stamped on it, but they can't see "too small a sensor" written anywhere. It will sell because of this.
To people who don't know about control over depth of field in photography, who have never attempted to take night shots, to name a couple of things.

I was just talking to someone yesterday who was thinking about upgrading her old 3MP camera, and when I mentioned sensor size, she asked me "what is a sensor"? To that person, I would say, get one of these... but then again, if you target that market, who cares about RAW?

with WHAT camera can you NOT get close enough to get a semblant of DoF? this is no special capability!
and of course it is for the ignorant! when they have an XZ2, why else would they come out with this?

nosnoop: Why no 5-axis stabilization?

If they can put the 5-axis stabilization in lower priced SH-50, why would they not put it in their "premium" XZ compact? This would go a long way to justify its price.

don't forget the little robotic arm that will press the shutter button for you too! ;-p
