What the video world desperately needs is separate channels for musak and voice so that the former can be muted if it is too intrusive or revolting. This video is probably very interesting but is spoiled by the horrible racket between the spoken sections.

Chris2210: I thought that was a very fair review. Mac haters always claim you can get the same spec for half the price. That rarely seems to be borne out once you look at putting similarly quality components together.

However, this is a very expensive high end machine and the idea you can do absolutely nothing to tweak it once it starts to be superseded in 6-12 months time is a problem. As is Apple's more recent habit of making even things like RAM [especially as they'll fleece you against the general market cost] and internal drives, non user-upgradeable.

For people who use FCP and AE on ultra high resolution files, it may justify its cost. That's not me, nor I suspect 99% of the hysterical anti-Apple brigade who will wail and gnash their teeth about this.

It appears to be a law of the universe that every fanboy must be counterbalanced by an anti-pole. Logic seems to be equally repulsed by these two substances.

Calm down dear - it's only a PC.

Regarding the comment about Nikon's optional compression curve, there's nothing optional about it nor Nikon's CA processing; Sony are not the only company to do this. NEF's are processed in Capture NX2 to remove CA, to improve noise, DR and to correct exposure BEFORE the user has his input. All of this processing is lossy.

This is easily seen by viewing a NEF in Corel Photopaint which displays the NEF in all its original unprocessed glory. It's evident that the amount of automatic CA removal applied in NX2 for modern electronic lenses is startling. Even pro lenses such as the 17-35mm f2.8 don't fare well. Old metal lenses, which the camera cannot recognise due to the lack of electronic connections, usually show little CA in Photopaint.

Angrymagpie: I personally use Aperture to keep all my RAW images, and LR to process them. I often wonder if the Aperture does some sort of automatic lens distortion correction with these updates. For instance,the RAW files seen on the Aperture do not look as distorted as seen on LR (unprocessed). It becomes really clear with high distortion lenses like the FE28/2. Any thought? Thanks

That's a really interesting question. I've noticed that unprocessed RAWs in Corel Photopaint show really bad CA for some modern Nikon lenses whilst old manual lenses, for which the camera supplies no data to the software, are near perfect.

It seems that the manufacturers are relying on post-processing rather than lens design to reduce CA (and distortion) and that RAWs are not quite as raw as we're lead to believe.

Interesting samples but I have to ask - why so much CA in some modern lenses? Optically (i.e. ignoring their autofocus and VR capabilities) some of the lenses in this test are nowhere near as good as my 40 to 55 year old pre-AI Nikkors. We seem to be going backwards although I suppose it's possible to mess around with PT Tools to reduce the problem.

groucher: This heavy and expensive lens is nothing more than a 28mm lens with a bit of leeway on either side and plenty of CA. Stay with a 28mm prime for less cost, weight and better quality.

I'd get your eyes tested or invest in a new display if I were you otherwise you might end up throwing a lot of money down the drain.

Not bad in the centre of the frame but the edges and corners are shockingly bad. Think I'll stick with my old metal Nikon primes - much better.

Let's hope this stupidity convinces a few more people to vote NO to the EU. Our democracy is being stolen by a bunch of incompetent, greedy and corrupt unelected bureaucrats. The idiocy going on in Greece should help too.

I hope this goes through. It will add many much needed 'NO' votes in Britain's forthcoming referendum on membership of the corrupt, incompetent, expensive and useless EU.

In reply to:

Shirozina: The issue with compression artefacts is way overstated. Anyone doing a normal looking processing job on that test image would not boost the sky that much and the artefacts don't show. 99.9% of image are the same that are exposed correctly and not processed with extreme shadow lifting. It only happens with very, very high transitions from light to dark across a sharp line which is also quite difficult to achieve with many lenses in real world situations as they can't create this contrast change anyway. Noisey shadows from limited DR are a far greater real world issue with Canon RAW files that don't have lossy compression so for 99.9% of users the Sony RAW file has a major advantage and not a disadvantage. Most of the people who get agitated about this issue seem to be non A7 owners and the examples posted are few and far between. If it were a real problem the forums would be full of 'samples' and they are not............

Michael and Rishi, if you do a bit of statistical analysis of the image data it is possible to determine how many bits of DR are captured. My analysis of the D700 data for example, showed that it captured 11 bits at its optimum ISO. As the ISO is increased, the lower order bits become swamped by noise. Strangely, the D700 captured fewer bits at its LO settings - slightly counter-intuitive.

Without doing the analysis (I don't have access to the A7), I don't know how many bits of DR the Sony cameras capture but it seems likely to me that Sony have matched the RAW format to the capabilities of the electronics.

matthiasbasler: A question to the community (or dpreviewers), since the topic of battery life is often discussed here:
One of my use cases is timelapse photography. Many cameras do not allow to change battery while on a tripod so battery life *is* important. Leaving accessory grips out of discussion for now, is there anybody with practical experience just how much the battery life of a 300-CIPA-shots rated mirrorless camera compares to a 450 or 600-CIPY-shots rated DSLR in this specific use case where the camera is on/standby for hours continuously and shooting, lets say, one photo every 15 or 20 seconds?

I have an EOS650D, rated 440 shots, and during a night timelapse session at ~20°C temperature it worked 5.5hrs with one full (original Canon) battery. It did roughly 1000 shots every 20s with 4s exposure each.
Do you have any comparable data for a mirrorless ILC cameras?

The Samsung NX100 does about 1300 shots @5sec interval (about 4.3 hrs) on a full battery charge at highest res. I have tried longer intervals but the battery life is no better - the battery must be depleted by the display which cannot be turned off, rather than by the shutter.

The best mirrorless for timelapse would probably be the Nikon 1 thanks to the huge battery but Nikon in their wisdom? have decided that the max. number of shots is limited to 500 (on the V1).

Medium format starts to gain some of the useless clutter and featureoids that bedevil smaller formats. Depressing.

Joachim Gerstl: I understand that we all hate to change lenses but this is ridiculous. Next sensor or AF innovation and you have to trow away all your lenses instead of just replacing your camera.
Just to be different is not enough.

If you're a landscape photographer it would be far cheaper to buy only the DP2 Merrill (45mm equiv. focal length) and a copy of PTGUI.

I have the a6000. You're right about the Sony lenses although the kit lens is good for the price. The weirdest thing about the a6000 is that the jpgs are really good but the raws are rubbish, showing excessive noise reduction and over-aggressive sharpening even if you turn these parameters to minimum.

Kiril Karaatanasov: It is a nice 1930s camera. We live in 2015. I saw no mention of the public SDK and app system.

Sure such camera will appeal to die hard retired people. Can Fuji and the other Japanese companies please enter into the 21st century. Wrist watches nowadays offer more like GPS, App support, gyro like, accelerometer (minolta had this 10 years ago), Bluetooth 4? How will this camera operate on a drone? How will it fit a film right?

Really DPreview include some more modern criteria. Could 19th century knows and dials is not the modern enthusiast needs. Build in intervalometer is nice but today we need advanced bulb ramping not a kitchen timer.

That depends on whether you want a tool for photography or a kidicam covered in useless intrusive gimmicks. Personally I prefer the former.

This new lens is lighter than the old 300mm f4 and has VR but as far as these samples are concerned, IQ seems to have taken a step backwards - they seem to lack the crispness of the old lens.

Koray: Capitalism at its best. After benefiting from decades long hot cash flow from "thrifty fifty" plastic junk, Canon decides to release an updated version. Only because a Chinese manufacturer copied the older version and released it at half price. Not that they care about the customer base, or thrive technological development.

Just cash, my friend, hot cash.

You sound as if you're unemployed or a public sector worker. Either way you have no understanding of the way the world works.
