rrccad: excellent idea .. making truely portable ILC's such as the Nikon 1 or this one are really what MILC needs to be, not canon or sony's APS-C or even sony's FF.

balanced lenses and a really really small total system kit, and with IQ good enough unless you are shooting in a bat cave all night.

"balanced lenses and a really really small total system kit, and with IQ good enough"

I agree but instead of the Nixon 1, I'd rather go for M4/3. Better IQ, more lenses, more bodies, more accesories, etc. for similar size and sometimes smaller depending on body/lens combo.

goshigoo: Panasonic is really doing very well recently (except the 42.5 f/1.2, but we can just ignore it since we already have 45 f/1.8)

The recent releases of GM1 / GX7 / GH4 / 15 / 12-32 and the upcoming 35-100 are on the right path of m43; the true spirit of m43
in terms of pricing and portability

I hope we will see a 8mm pancake prime or 9-18mm from panasonic soon


Base on your your linear equation using a Canikon 85/1.8 @ $450 as base, then the lenses below should have the following price:

Canon 50/1.8 = 156
Canon 50/1.4 = 257
Canon 50/1.2 = 350
Canon 85/1.2 = 1013
Nikon 85/1.4 = 744

Except for the 50/1.8, everything is way off. Further, the Olympus 45/1.8 would have better "cost performance" than the Canon 50/1.2 based on the same logic. That doesn't make sense. In fact, none of this is true.

radissimo: For a second I was thinking about this kit, but why not get Canon G x1 mark II with nice bright zoom lens, bigger sensor and for less?

"I DON'T think that the low light performance will be much different between this Canon GX1 mkII and GM1 with this lens"

Wrong. Current m4/3 sensors have better performance than the one in the G1XmkII and pretty much all Canon APS-C.

So, add a brighter/sharper lens in front of the better sensor, the GM1 or even the cheaper E-PM2 will out perform the Canon any day, or is it any night. Actually, an E-PM2 + 14/2.5 might still be better despite the lens being slightly slower than the G1XmkII and the combo is much cheaper.

FYI, size difference is smaller. The crop factor of the GX1mkII is 1.92x in either 3:2 or 4:3. At 3:2, effective sensor height is 12.5, shorter than m4/3 which is 13mm.

justmeMN: "This could be a cultural difference, of course."

No brand of mirrorless camera sells will in North America and Europe. We don't have a "if it's a little smaller it must be better" mentality.

@Tonio Loewald

I don't know what mirrorless you speak off. Anyone I hand my Olympus mirrorless to can easily use it like an SLR or camera phone.

My wife, not camera savvy, does exactly what you say: turn mode dial to green/auto, look through viewfinder and push the shutter just like any SLR.

It even gets easier for people who've only used a phone as a camera before because of the touchscreen: old at arms length and tap on screen. Try doing that on a typical DSLR. How many of them have touch screen and how many can focus in Live View (CDAF) quickly? I've seen so many people who obviously just got a DSLR for the first time because they try to use it like this and just get furstrated.

Hawaii-geek: OFF Camera Flash triggering , on a small camera ... Nice ! you would think that is a NO Brain-er for any small camera. ... RX1/r comes to mind, I am not bitter :)

About time. Even the very cheap E-PL1 can do multi-flash wireless remote control from its built-in flash.

In reply to:

Plastek: " We have done some studies where we presented consumers with a DSLR and a mirrorless camera and ask them if the image quality was the same, which one they would chose, and generally they chose the DSLR." - I would answer in exactly the same way. Simply because DSLRs offer by far wider choice of lenses many of which are superior to mirrorless glass. And then there are whole systems of accessories, flashes, and well: everything else that in the end creates a photograph.

So: Yes, DSLRs DO offer better final image quality, but reasons for that go beyond body itself.

Maybe on FF. On APS-C DSLRs like the majority of users, it's difficult to say that mirrorless is inferior as a general statement.

I mean, I've had Rebels for years and Canon never made an EF-S 'normal' lens (around 28-35mm) and only ever bothered making only ONE EF-S prime. Yes, you could use EF (FF) lenses or lenses from third party, but it's obvious that Canon's main focus is FF. A while ago, Nikon was in a similar boat, but luckily they've put more effort in making DX lenses. Now, compare that to the number of mirrorless lenses released so far in the last few years, particularly in m4/3. Even Fuji released 3 primes right off the bat. Mirrorless lenses, like m4/3, perform just as well as their DSLR equivalent mounted on a APS-C bodies.

As for accessories like flash, m4/3 is using the same flash system as their DSLR. Also, even the cheapest body, like the E-PL1, has multi-flash wireless remote control built-in, where as you'd need a middle tier body or higher to get that on DSLRs.

Jose Sentmanat: This is all good as usual with your reviews, I am still hoping that I can get a lot for all of my formerly expensive SLR cameras and lenses to that I can afford to by one decent DSLR or Mirrorless Digital Camera. Sorry I must wait also for a miracle that prices come within my reach. :(

"Poor cost performance"?
Like a T5i, the EM-10 has an articulated touchscreen but at a lower price and you also get better IQ, IBIS, WiFi, larger viewfinder with 100% coverage, more physical controls, metal case, and so on. Stop your BS.

In reply to:

SelfMotivator: A 50mm slow lens f/2.8 for $US1K, damn. Fuji 56mm f/1.2 sounds like a sure winner.

Edited: I did not see MACRO so no comparison. Fuji 60mm f/2.8 macro is only $US650, a much better reached focal length if I shoot macro.

Worthless for me anyway :).

It is a "Zeiss" so it is expected to be expensive but the price is steep for a macro none the less. Makes the Oly 60/2.8 weather proof macro look like a bargain at $400.

In reply to:

Paul Guba: I would have brought the 12-40 18 months ago without hesitation, but with so many more mirrorless options now I really don't feel the compulsion.

Other mirrorless systems still don't have weather sealed and constant f/2.8 zooms.

In reply to:

Gazeomon: Surely a very good camera, but I'll wait for more info on the Pentax K3 which is not much larger than the EM-1 but has a new sensor. I also miss the top panel display on the Olympus to which I got so used to on my DSLR's (all the important info's at a glance). But there is a lot to like on the EM-1.

The EVF has all the info you need and it shows you what the sensor "sees". Plus you get other info like live histogram, grid, level, etc.

In reply to:

Sergey Borachev: I see a lot of reaction from DSLR users.

Especially for all those who keep pointing out the small M43 sensor, I wonder why they bother to read this review at all, and why they then feel the need to post what we all know - that M43 cameras have a smaller sensor, no good, blah blah.

Shouldn't they be happy about what they use, the bigger sensor and cameras etc, and not feel so threatened?

@Henry M. Hertz: last time I checked you can still buy an m43 camera w/ lens for less than $500, like the E-PM2. How much is a 6D/D600 + lens, and how much bigger and heavier is it? As for those EVFs that suck battery, the newest FF bodies (A7/A7r) has 'em.

Dougbm_2: Could be quite interested in this but then again I could just buy an 18-135 for my 50D for about $400 (or 15-85 for about $500). Sure they are not as bright but depth of field will be better.

DoF is either shallow or deep, not better. At any rate, being f/5.6 at the long end makes those zooms both slower and have deeper DoF than the RX10.

In reply to:

Gordon L: I love the concept of a compact full frame camera, long overdue from camera makers.
A thousand bucks for a 50mm f1.8? gimme a break. $800 for a 35mm f28? As usual Sony is not delivering decent lens choices. Their marriage to Zeiss is unfortunate. Ziess produces huge over-build over-prices clunky lenses that often test out no better than much cheaper lenses from other makers. Sony nees to take a few pages from Fuji, talk to some actual photographers. I've never even considered the NEX system because of the lens choices.

@rxbot, as JackM says, w/o an adapter to mount existing EF lenses, the the flange distance has to be the same, which means the camera is still going to be bulky. It would be like the Pentax K-01.

An A7 with an an alpha adapter is still smaller than any FF DSLR body. It can also use different adapter to mount lenses from different manufacturers. It's a better approach. It makes more sense than keeping a having a mirrorless body with an SLR flange distance.

In reply to:

Wabznasm: I've confused myself. Can someone please assist a noob? :)

I love using my Super Takumar 55m 1.8 on my NEX 5.
Will this lens be suitable for use on an A7 / A7r? Will it change the focal length? and will it be more suitable on one over the other?

As FreedomLover said, FL stays the same and when mounted on the A7, FoV will be back to original (55mm on FF/135mm format), which is wider than on NEX5 (82.5mm with crop factor).

As for vignetting/colour shifting issues, they seems to exist with certain wide angle lenses. Less wide lenses (35mm and up) such as your standard/normal lens shouldn't have any issues.

In reply to:

Paul JM: no OIS at this price ?
no interest sadly. Would love a fast wide prime with OIS to use with the Blackmagic pocket

Only 1 m4/3 prime has OIS that is currently available and this is much wider and brighter than that so it is to be expected. Besides, if you mount it on a GX7 or any Oly body, it'll be stabilized.

In reply to:

MarceloSalup: I would hope most of the people reading this site would have those, for sure. I recently added one more: a bean-bag-mini-tripod. It is a beanbag with a tripod head and great when shooting in locations where the mini-tripo is too clumsy: for example, windowsills, held against a light post... the bean bag conforms to the surface really well.

Haven't seen one of those yet so I'll check them out. Personnally, I like those mini flexible tripods (gorillapod). You can wrap them around tree branches, stand them on rocky/uneven surface, etc.

In reply to:

RDCollins: Sorry, Sony, but I need an electronic or optical view finder! The option you offer is far too expensive and compromises the camera's compact size.

At almost $450, the FDA-EVM1K is definitely expensive. Also, there really are no other options. Compare that to the Olympus VF4, which has the same resolution but cost only $280. On top of that, there even cheaper options: VF2 and VF3.
Anyway, the RX100II is nice and all but if one needs an EVF, might as well go for a NEX6 or GX7, which are also wifi capable.

That is not cold. They are claiming it won't freeze up in the cold so why isn't it good to 30 below which is what our winters generally hit when bad weather comes in.

Sounds nice, but I already use my gear in sub zero temps with good success.

It says -10C or 14F, so definitely subzero.
