peppermonkey: Well, Panasonic m43 cameras (GX8, GH4, G7...) can focus to -4EV...so I can't see why the Sony focussing to -2EV would be all that surprising, or any mirrorless these days.
4k AF of GH4 is still much better than the video AF of most of DSLR's at 1080p.
bgbs: Sony is the winner in the mirrorless department, and is now rivaling DSLR's in other respects.
If winner means best high ISO and shalllowest DOF, then Sony wins. If not, then Panasonic, Olympus, Samsung are great competitors
Most of the GH4 AF tests are done when shooting 4k. At 1080p the focus is much much faster. And AF for stills is still much much faster. I would like to see see a quick update to the article how GH4 does against 7R II. Also test tracking, not only AF-C. Just my 2 wishes. Thanks.
At the official website, in 'm43' mode, the lenses become the heaviest and biggest of all of the different mounts. Not to mention the least useful focal lenghts.
That's because µ4/3 cameras are smaller and lighter due to the shorter registering distance. µ4/3 still wins in total weight (50g is not much, even the excellent Panasonic 14mm f/2.5 weighs more (55g)).
belle100: Judging from the price, they must all be much higher quality. However, I don't understand why it needs to be higher quality than their still counterparts. I mean the resolution of 4K is 4096x2160, which is much lower than those of still image (typical 24MP) required.
Actually, 4Mpix would be enough for today's cameras, because 4k in most cases does not really resolve 8Mpix. Just like Canon 5dMkIII actually only delivers 720p in 1080p mode.
Anyway, getting the 8Mpix equivalent sharpness at the corners is not cheap, especially at T1.5! Also, focus breathing is another thing to be considered.
Lassoni: I'm curious whether it's phase detect or only contrast detect auto-focus. If it has good autofocus for movement like samsung nx1, then maybe it could be interesting.
I just watched the video I posted above again and I was surprised how did the mirrorless cameras did. The conclusion: "All the mirrorless cameras we tried today are faster with faster frame rates per second than any DLSR in their price bracket"! The LCD/EFV introduces small lag, though.
Yes, like mosc replied, it has Depth From Defocus (DFD) functionality. Unless you are shooting action, the AF should beat entry-level PDAF hands down. In terms of action, it's at least very close to entry-level PDAF. See https://youtu.be/up8K_xd_iwU (GX7 and GH4 share the same AF technology).
mgm2: These images are indeed nice, but quite frankly I am not sure they are better that what I get with my Pentax K3 and the Tamron 90mm 2.8 Macro.
@ecka84Low-light performance is only a part what the low F number gives. DOF is equally important. If you are interested in light captured, then we should be talking about T, not F. You can adapt these lenses to various camera bodies, and the low-light-performance (high ISO) depends on the camera body. However, here we are talking about lenses, not cameras.
You are clearly suggesting that K3 and "Fuji" have similar low light performance based on tests. Is this even true? If "Fuji" is better in the test (because of "cheating"), you still get better performance overall (in real life shooting, who cares about the ISO number, as long as you know what you will get?).
A great short article by DPReview! Good work!
wandiba56: As of now I know no camera that can produce colours as striking as Fuji’s...Bar none, Fuji gives the best colours one can ever imagine. And I have used far more expensive, much more popular and higher megapixel capturing devices yet I dare say they all come short to meet the exquisiteness of Fuji colours...Well done!!
I have a strong feeling these shots were not taken by Rishi...
Good luck with WB.
tb06mar: Confused. Why Panasonic developed 2 lines: G-series and GX-series. What are the differences between them?
GX-series is a direct competitor for Olympus OM-D-series and Fuji. GX-series has a smaller rangefinder style form factor. It is optimized for stills performance (IBIS).
G-series has DSLR style form factor and it competes with mid-range DSLR's. GX and GH series offer the flagship models, whereas G-series offers amazing value, excellent ergonomics and direct physical control on the functions.
Then there is the GH-series, that actually competes with full frame cameras (and Samsung) on video quality, plus doubles up as "actually an excellent stills camera".
GM-series is as tiny as possible. GF-series is for entry level photographers and mainly competes with Olympus PEN EP- and EPL-series.
Bueche: Probably a good camera, but far too small. Anyone who knows if an extra grip will be available?
If the camera is too small, check the G7 or GH4. So far Panasonic has provided external grips only for the latest GH-models.
Kim Letkeman: Panasonic does it again ... releases two new cameras very close together and takes the opportunity to completely screw the more ergonomic but lower priced G line ... and then they wonder why it does not sell as well as it should lol ...
Is there anyone on the planet (and in his or her right mind) that would have refused to pay a few hundred more for the G7 with this new technology in it? The G6 is already more camera than many need and remains the budget choice for superb ergonomics and excellent images and video. So the G7 / GX8 could have been a matched pair at the high end with little to differentiate them cost-wise. The ergonomic differences are legion and that should have been the plan IMO.
(Un)fortunately, the tech is developing so fast that the just-released cameras are already outdated. Maybe Panasonic could announce G7 mk II?
Zeisschen: It sounds like a much more simple but at the same time higher resolution approach compared to the Lytro. The difference is, it won't capture just one shot but a short video sequence. That might matter for moving subjects.
Rolling shutter could also be an issue there, but eventually Panasonic sensors are als fast enough like Sony stacked ones to eliminate it.
Focusing from min to max distance takes about 1s or less on current Panasonic lenses. Currently you get easily 60 fps at 1080p (2MPix) and 30 fps at 4k (8MPix). Next year 120 fps at 1080p and 60 fps 4k?
I do not see see a reason why small upgrades should not be made. This upgrade is for those who don't own a GR yet.
Stuart: Hilarious blunder buss of a lens. I have the equivalent Olympus m43 lens. It is tiny vs. this and can be easily hand held. Using CS anti blur filter gives even sharper results hand held even when using digital zoom to 1200mm equivalent.
@zsedcft when cropping, blur needs to be compensated with faster shutter speeds. It's important to tell this to the camera, when using any of the manual or semi-automatic modes.
JPR.lda: Is the silent mode really silent like on the Sony A7s???
Yes, the shutter is totally silent. On Panasonic G-series, totally silent electronic shutter has been available since G5, 2012.
Pitchertaker: Still trying to decide between the Olympus and Sony lens systems to invest in for landscape, perspective, and closeup images.
For my applications are primes a better choice than a zoom?
Should I grab an EM-1 and throw on this new 7-14mm f/2.8 or go with their 12mm f/2.0 & 17mm f/1.8 instead?
Should I go Sony a6000 or A7 with their sole 24mm f/1.8 prime, or would their 18-105 f/4, 10-18 f/4, 16-70 f/4 or 16-35 f/4 do just as well?
Between the Oly 60mm f/2.8 macro and Sony 90mm f/2.8 which is better?
Actually, because MF ring on most mirrorless lenses is on-the-wire, MF ring on these lenses could be used to set aperture on any camera that supports it, via firmware update. Samsung might have a patent for this, though?
lglass12189: ...and why is 4K video a must-have feature?
Well, if you look 5D mkIII 1080p video after seeing a 4k video from GH4 downscaled to 1080p, you would think that the 5D video is not in focus. Well, this is usually not the case, because the downscaled 4K shows so much terribly much more detail. You don't need 4k TV to see the difference, just like a 20Mp image will look much better in the 2Mpix Full HD screen than a 4Mp image, all other things being equal.
Edit: Of course anything related to "must-have" is related to marketing. Anything less than 4K is yesterday's tech. I love the sense of humor of the writers, although I do not always get it myself.
Treeshade: Maybe I should buy this one and keep my GH3 as second video camera? Seems to be an upgrade in every aspect.
GH3 vs. G7? That's an interesting comparison. It's a shame that neither has the multi-aspect-ratio sensor.
