In reply to:

Vitruvius: Weakest link relative to Oly OM-D E-M5 is the lack if IBIS. Weakest link of the E-M5 relative to the G6 is the video.

The PANASONIC / LEICA opted for OIS for allowing a faster response to movements, prospectic correction to the angular change and ability to get closer to the sensor with the lens giving more freedom to the designers of the optical assembly. The disadvantage is that each of OIS lens must have one, thus more expensive, and the rotational motion of the lens axis (Z-axis, perpendicular to the sensor) is not corrected, although this movement is very limited in practice. The IBIS allows cheapen the objective and make the correction of the rotational motion on the axis ("Z") of the lens (including correct the horizon angle) but does not address the prospectic variation due to angular changes in the X and Y axes of the sensor. I believe that the sensor will not move as effective as moving a small block of lenses when it comes to compensate for high frequency instability. I also think that in terms of durability is better shake a small block of lenses than the sensor with its flat cables.

In reply to:

lensberg: One thing is abundantly clear... Canon still is the king of JPEG's beyond a shadow of a doubt...

As always with Nikon's new iterations... RAW remains a muted affair... A fractionally cleaner image by the D600... but details are quite blatently smudged away... I guess thats the price one has to pay for having a cleaner RAW image at high iso's... Canon's 5D III slightly noisier, but visibly superior detail retention... especially at 12800 & 25600

I´m not so confident! Did you compare JPGs high iso with Lumix GX? I see a big cloudy image for Nikon and much more details in Lumix GX crop, even been Lumix GX image smaller... I stay with Lumix GX, even in RAW! Compare!

whiteheat: It would be really great if Pentax and Olympus both produced a nice Full Frame camera as an alternative to the standard Canikon fare. A little competition would be good for the consumer, giving more choice and balancing price levels out much more equitably. Come on Pentax, come on Olympus - you can do, you both have the smarts and pedigree to do it, so do it!

Olympus has exactly 0 AF FF lenses. Why would they even attempt that?

And most important, 0 money...

Stollen1234: simply as with all technology trend the FF will become cheaper and more widespread..this is good news

the future will be without any doubt an affordable FF FF cameras for sport and birding..etc

..."and that one day APS-C and maybe even M4/3 sensors might surpass the performance of FF sensors."

Perhaps but as a rule whatever is discovered that improves APS-C can then be worked in to FF but with larger photo sites, so it seems to me unlikely.

That is not true for everything. Larger photo sites means large charges, so large drain of energy and generation of heat. This is a big trouble to do movies as Full HD at 60p and make batteries last. Even a m4/3 needs to be cooled to withstand continue use. So, if the consumer demand more capabilities in movies from the cameras, the FF can be abandoned.

Well... what about picking your password when using a bankomat and spread it to cell phones? Will you remember to switch off before go to WC? Big Brother works by the fact that after some time, you forget that are on line! IMO this device is intended for forbidden use!

Artpt: I have three boys (7, 5, 9months) and have taken plenty of pictures over the years with a GH1. For a consumer like me, the mix of AF video and great images make for a compact system that I can later use to montage vacations for the grandparents....looking forward to the review and checking out a local store in the Chicago area that has this soon!

How did you manage to get three boys just two months apart each other! Do you have three wives? You are faster than Lumix auto-focus!

In reply to:

Jacques Gilbert: I think 90% of the comments can be replaced with this one:

This is a very confusing article. You list a number of cameras, in a well defined category, and place them in groups according to criteria that you explain. But, somehow, you manage to ignore the one I just bought and I have crowned my favorite after extensive research. To add insult to injury, you list cameras that I absolutely despise - again on the strength of my extensive research on the web - as if they were worthy of mention. I cannot understand your motivations, you must either be incompetent (as shown by the errors that I can catch), or bribed by all the companies that have to resort to such shady practices to compete with my favorite brand.

If this is what you wanted to say, please just copy and paste, the rest of us can then save time and skip your comment.

God Job! If so many people are here discussing about this roundup means that there´s a lot of interest in this area! You get a HIT !!! Now, complete with missing points, give more detais and you´ll get a herd of people visiting your page! Congratulations!

In reply to:

jeffharris: The GH2 is "a pretty capable stills camera in its own right"?

Pretty capable? That's a pretty funny quote, since it's the best stills camera of all the Micro Four Thirds cameras to date. It's very high quality video is a bonus feature, not it's primary with stills tossed in, just because.

How about a little mention of the multi-aspect ratio sensor, which really is one of it's primary features and separates the GH2 from the rest of the M4/3 line-up.

Quick, if a bit rough, description: it's an 18MP "oversized" sensor that adjusts the area of the sensor that is used for shooting different aspect ratios (4:3, 3:2, 16:9, 1:1). It maximizes final image resolution with this technique, rather than cropping a full-sensor image and losing resolution to simulate differing aspect ratios.

Good and informative article! Thanks.

We say that Lumix GH 2 doesn´t crop because the sensor corners goes beyond the resolution circle of the lens, this is the reason why no format selection give you 18 MPixels. The others use a sensor inside the resolution circle of the lens and get diferent aspect ratios by cropping. I hope someday Panasonic give the option to save the entire 18 MPixels data and let me do the crop. If I have blue sky on the upper corners and grey asphalt on the botom corners, I would have no concerns about CA, distortion, blure or vignetting... Could even be interesting pictures...

But actually SD can be faster...

In reply to:

Doug Pardee: CFast was never intended for consumer applications — it's intended for industrial equipment — so I guess this is CFA's attempt to get back into the consumer world. Given the almost universal adoption of SD/SDHC/SDXC in current consumer devices, CFA's got quite the up-hill struggle. Maybe in some of the pro equipment. I guess we'll see.

And I have to agree... "SD" was inexplicable but at least pronounceable. "XQD"? Really?

Maybe "XQD" stand for "ExQuisite Device"

Jogger: "XQD" .. did they use a random letter generator to come up with that

Maybe stand for ExQuisite Device
