MattBrisVegas: One more reason to think of switching to a m4/3 system EXCEPT why are m4/3 lenses so expensive? I can't help but compare this 75mm f/1.8 for $900 to the Nikon 85mm f/1.8 for $430 (both today's prices at B&H). The m4/3 lens is built to cover a smaller image circle, so it uses much less optical glass. So why is it about twice the price?
Several reasons. One is what Marvin Clapp said, telecentric design. Second is low volume, like T3 said. I'll add more.
Size: It's not easy to create smaller lenses with the same amount of performance.
Aperture: 7-blade circular aperture design is common in m4/3 lenses. That design is usually found only in high-end Canon and Nikon. 9-blade circular is standard on all 4/3 high grade and up lenses (there are exceptions). That's why Olympus lenses have far superior bokeh.
Design: 4/3 and m4/3 lenses are created ground up for the sensor size they're for. R&D cost is higher. Most cheap Nikon and Canon lenses are designed for 35mm FF format, so their R&D cost is already amortized.
Resolution: Don't know about m4/3, but 4/3 lenses have almost the twice the resolution of FF lenses, because it has smaller sensor, so it needs that much resolution to compensate for sharpness. That means the glass have to be higher quality. Lots of ED glasses are used.
Nice, a photo shows how it performs with a Panasonic camera. :-) WB is incorrect. Nose is out of focus.
I appreciate this photo to show high dynamic range situation at night, which is the nastiest of all lighting situations since we tend to overlook that problem. Aperture choice again is pretty bad. CA is expected, especially in the out of focus area. It's a matter of how bad it is, and how easily one can correct it with software. It looks like the person who shot this intentionally over-exposed the photo by 1 stop. Given this is ISO 6400 photo, the performance is admirable. I just don't agree with the DoF choice (the "Ice Cream" sign should be completely within DoF. Dog sign is fine to leave it OoF to show CA performance).
That issue is already shown in one of the Olympus's official sample. The fringe is a non-simple kind with double rings.... Appeared to be some sort of over-correcting with software (Olympus needs to refine their processing engine to handle this lens). Everything else is pretty good, given how badly exposed this photo is. DoF choice is just nasty.
Those are not fruits, btw. Those are flower buds of fuchsia.
For those mentioned about bad review photos, I tend to agree with you. I think the DoF choices are pretty bad for many of the portraits. DoF should be enough to cover both the nose and eyes, not wide open for every shot. As for overexposure on dog portrait. I think it's fine. We do need a few over exposed shots to show the lens's CA (or lack of). There should be more photos about bokeh and light spheres and light stars, we we get to know every character of the lens. Sharpness of this lens is a given (it's an Olympus HG), but bokeh quality, the second most important character of a lens, should also be shown before I would consider the lens.
Yes, they should go for a meeting and create a chart of goals need to accomplished. They need one photo for each possible real world scenario, each with a variation of using wide open and best aperture of the lens. With different lighting scenarios.
citizenlouie: Is the youngest sister in Downton Abbey Sybil or Edith? Because I really need to know your judging criteria. :o)
Thank you for treating my question seriously. ;-) It's charming to meet a fellow Downton Abbey fan on DPR. Yeah, I can't wait to see the rest of Season 2. Season 3 is announced. Yay!
I have a photo lost its Explore status on Flickr, so I guess I'll try my luck to redeem its honor.
It's just a Downton Abbey joke type of thing. But I agree, each is beautiful in their own way (though I find Edith scheming...). Sybil has some inner strength with her. Mary is very elegant, but she is kind of opposite of Sybil, because she appears to be strong, but she is actually more vulnerable than the other two. :-) I just finished Season 2 Disc 1, so don't spoil too much detail! :-D Yes, Anna is lovely, loyal, ambitious and faithful.
Let's see if I can find some photo that would exhibit inner beauty (this conversation actually is helpful). :-D

citizenlouie: It does work for landscape orientation photos, but doesn't work too well for portrait orientation photos. Still, it's a nice upgrade. My photos are meant to be viewed super size, and I appreciate Flickr makes my photos look better now.
I just wish in the photostream view will be upgraded to "justified view."
Yes, they just did! That's so great. And they center-aligned the portrait photo also. It looks so much better. Thanks. :-)

Congrats! :-) Nice photo.
They Stole My Idea ! ! !
Though my original plan is to implement a B&W only camera, but I would allow people to extract the color version if they shot RAW.
Now I hope Kodak doesn't steal my idea of making film-specific camera.... Wait, Kodak doesn't make digital camera anymore.
Nice article. :-) Very insightful and very helpful to everyone. It's something everyone should at least think about when they take photos.
I think stopped caring my audience though. :-( They're a diverse group of people. If I satisfied everyone, I would stop having fun taking photos and might get too frustrated when someone doesn't like them, which is something to think about also: it is totally okay if someone doesn't like your photos....
Yes, 17mm remake.... 35mm equivalent focal length is a very useful, and it's a shame 17mm f/2.8 was so awful I returned the entire E-P2 kit. The speed issue is not as important as IQ to me.
25mm f/1.4 Leica is already an option, so if you need one that is the one to get. No need for another 24mm f/1.8 (inexpensive option for that focal length is Panasonic 20mm f/1.7).
citizenlouie: I wonder what's the point of using larger aperture to achieve DoF. Probably FF will eventually phase out....
I was being sarcastic. You can already do this with photoshop but you need to shoot two photos. One with the background completely out of focus and another with the foreground in sharp focus and merge two photos. It's a big hassle. For action shot like the dog, it probably is not that easy (but not undoable). This looks like an "automate" function. For macro, we can already do extended DoF by merge/stack several shots. Software solution for shallow DoF probably be inferior (actually all software solution is inferior than optical), but depends on what your needs and your threshold for quality, it can be helpful sometimes, if you don't mind compromise.

veroman: I can't help but wonder why anybody thinks they can judge a camera's real-world performance by viewing images ... 100% or otherwise ... on the web. When all is said and done, the OM-D E-M5 is a somewhat better M4:3 camera than its predecessors,but not by much, I'm afraid.
Truth is, it's highly doubtful anyone will see real, palpable differences between this new camera and the E-P3 or E-P2 for that matter when printed to even large sizes.
No, what the OM-D is all about ... as with so many products these days ... is its body design, and I happen to like it ... being an old guy from the film era. Underneath the skin, though, it's yet another M4:3 camera ... and apparently a good one. But it's no Nikon D7000/Pentax K-5/Canon 5D beater. How could it be?
Don't forget about handling and the lens you use with the camera. Your result may not be the same as DPR's because your shooting style is different.
razorfish: How sad to see all these fanboys of other brands badmouthing Olympus products. I never see this happening when Canon/Nikon/Sony products are tested. Clearly a four thirds sensor performing well brings out some kind of inferiority complex in these people.
You're not wrong about your analysis, but it's the same argument why Olympus says 12-bit is enough. The reason is (*drum rolls please*) a typical LCD monitor people use are 8-bit only. Most people, won't notice any IQ difference between RAW and JPEGs (with very low compression) unless they use a professional monitor, which specifically states it has 10-bit process engine and wide-gamut (97% sRGB and up..., yes, even pro models may not have 100% sRGB gamut, let alone AdobeRGB gamut). I rarely see any monitor that has 12-bit process nor 14-bit ones (those can cost $1,000+).
Most people usually capture their photos in 72dpi, which is fine enough for LCD monitor, but not print quality 300dpi. I really think this subject is really moot point for most casual photographers.
Pete_Murrell: I have only one question that may not be answerable by people in this forum however I will ask it anyway.I currently use 4/3rds stuff and obviously I love it. I was just wondering if anyone has heard rumours about Olympus releasing a camera with this sensor in the 4/3 lens mount range (Maybe an E-6 or 7)? ... because I can't see myself investing in a whole new range of lenses but based on this small snippet, this sensor is pretty special. Fingers crossed. Can't wait for the full review.
If I remember it correctly, 4/3 system uses 7 contact pins, and m4/3 uses 9. Two more pins are for CDAF, and that's the AF system that's been vastly improved in latest m4/3 models. They could try to miniaturize the current SHG glasses and adds CDAF mechnism to it, but many people already said before (in other sites), it's quite difficult to make SHGs smaller than they already are, though they are by no means small, and they are pretty darn heavy (because of the level of complexity in design and super large aperture). I don't see size conscious m4/3 users would be interested in such heavy glasses, even if they can make them smaller.
brkl: That's pretty remarkable. As good as the best of APS-C it seems.
I hope both of you and Hen3ry realize, I am not talking about color temperature (I use a gray card, so that's negligible), color saturation, direction of shadow and some such, I mean stuff that you will notice when you pixel peep, like detail, noise level, some stuff that makes your photo extra sharp, rather than aesthetic appeals, which can be done with any type of camera if done right. Aesthetic appeal is a subjective measure, which using it to judge the quality of the sensor, which is the main topic we are talking about, is unfair, don't you think so?
