dbm305: Another semantic point, but perspective distortion is just as bad a term. It’s not distortion, it’s how things sort of look from those perspectives, and exactly how they look projected to a two dimensional surface preserving straight lines. “Perspective effect” might be better...

Why not just "perspective"?

sirkhann: Finally! A good budget landscape mirrorless camera with ergonomics that will not make you sacrifice image quality for it. Up to now, you had to choose between Sony for IQ or Fujifilm dials and lenses.

I totally dislike all the colour artefacts and mushy greens that XTrans produces for landscape work, plus it takes ages to process their XTrans raw files.

That is my next travel camera.

@confused circle. I'm sure that this is part of the issue some find with the XTrans sensor. Some time ago, DPR in their tests would show the results of manufacturers' RAW files in different software and the differences were quite noticeable, often with Adobe not doing too well, to my eyes at least.

It is true that many have reported on what they perceive as a problem with the XTrans, so I'm not disputing something isn't quite happening for them. But I'm not seeing it. Could it be because I'm embracing the image as a totality and not pixel peeping to find flaws? Using my painters analogy, even they look terrible viewed close to. Chacun à son goût, as the French say.

Some people like Rembrandt, others Van Gogh. It's all a matter of choice; I simply prefer the X-Trans results.

Thorgrem: Nice competition for the E-M10 Mark 3. If only Fuji had a nice compact standard (pancake) zoom.

They do, the 16-50. This is a kit lens, and I must have one at the top end of its specification as the results I see with my X-E1, for which I got the lens as a lightweight carry anywhere option, are unbelievably sharp. And my lens is the earlier Mk I. I can't argue the case that all the 16-50's will be this good as undoubtedly there will be sample variations, but my sample really is that good that I've fended off buying the more expensive lens, despite its faster aperture and pro build.

thomas2279f: Must say the styling of Fuji mirrorless are excellent and hopefully Nikon will follow the same design. - this camera abeit the 4k option still looks like an excellent camera and good for photographers joining mirrorless at the entry level and then investing in the Fuji system.

Yes, but the guys are talking about design, not format, so I take their comments as valid.

I'm always puzzled when I see comments like this. I use the X-Pro 1 and X-E1 and a) I don't get mush greens, so I suspect issues are software related and we know that initially Adobe, for example didn't do a good job, and b) my image software and high spec laptop processes the RAW 24mb files in 1 second. I don't know how long "ages" is for you, but 1 second seems plenty fast enough to me. What I do notice is that the RAW file does take fractionally longer to load than other RAW files I have, about 1/2 second longer.

jorgepr: I have read a lot of Sony in its own forum
on the masterful Eye - AF in the A7III.
In the A7IV in a few months Sony will solve the problem.
Here are some examples:

I guess the reason for getting the eye sharply in focus, irrespective of how sharp the rest of the head is, is because when we look at people face to face we generally look each other in the eye, and we are comfortable with this. Consider how unnerving it is when people don't look you in the eye and, say, keep looking at your hair, chin or ears.

Also in portraiture if the eye/s are not sharp, we perceive the image as very poor. The soul is seen through our eyes, not our chin. :D)

marc petzold: Nice article, well written. And two of my all stars also being mentioned, Canon 5D and Sony R1.

Time travel back into 2005, the two most anticipated Cameras have been the Sony R1, and the Canon EOS 5D, when you've been serious about Photography. Luckily, i could afford the R1 into spring 2006, whereas i ever used it so, and still do...and the 5D a few years later, and also still being using it.

Both have been way long being superseeded by successors, but they still "get the job done" and both have some kind of unique look.

I won't depart from them, even it would being hard into some couple years, when there is no more internal years clock....so the EXIF would being wrong then.

Sony innovated right from the start of the digital camera evolution, let's say DSC-S70, S75...for instance, 717, their Mavica "floppy" cameras, and many others before, and after the mentioned cameras....the A850/A900 FF DSLRs, have been designed by Minolta, but came under the Sony brand then...because...

Hi, Marc.
Thanks for the link re the ETTR technique. This is something that I wasn't aware of but it does tie in with a thought I had regarding shooting high ISO (normal setting) in daylight. I discovered that noise was diminished a lot compared to high ISO shooting in low light levels and I realised it had something to do with saturating the sensor as compared to the gain being turned up under low light levels.

Noise with the R1 above, say, 400, will be perceived a problem compared to today's cameras, but it was very respectable at launch.

What I need to establish to my own satisfaction is whether shooting at 1600 ISO with +2 exposure compensation is better than shooting natively at 400 ISO with +0 compensation. Both cause the R1 to give the same overall exposure. What will be better is if in my personal experiment going the ETTR at route at 1600 ISO produces superior results to 400 ISO.

This is a fascinating subject which seems to defy logic.

LDunn1: Around 1985-7 there was a paradigm shift in the camera market. Minolta introduced the 7000 arguably the first SLR with a usable AF system across the range, and shortly after Canon launched their AF system answer in response, the Eos system.

Around 2003-6 another paradigm shift happened. Digital SLR’s became affordable & capable enough to challenge film. I’m thinking Eos 300d & 10d period here.

I feel we are currently another paradigm shift period and maybe have been for a few years with another year or so to go. The shift from DSLR to Mirrorless.

Within a few years of the SLR AF paradigm shift, manual focus only SLR’s all but disappeared. Within a few years of the Digital SLR shift, film SLR’s disappeared. Within 5 years, I wouldn’t be surprised if DSLR’s disappeared, replaced by Mirrorless.

Marc, well it was based on your final paragraph where you made an unqualified statement on the long life of typical dslr batteries. This gave the impression it was all down to it being a dslr battery.

Some people wouldn't make the connection that it was also camera dependent, a point you now say you were aware of. All's well that ends well. :D)

Marc, as one who also bought into the R1, I now have two, the W/A and Tele converters, and the bespoke flash unit. Yes, they were seen as expensive in their day, but you should check out DPR's own review where the price is compared to getting the same optical performance covering more or less an equivalent focal length, with the Canon outfit you'd need. On this basis, the R1 was seen as positively cheap. In fact, DPR concluded that the R1 was worth it for the lens alone.

That it didn't sell as well as it could (or should have done) was down to the plummeting price of entry level dslr's; I think it was Canon who first broke the $1,000 price point. Reflex cameras, film or digital, have always been promoted over any other as the one you should have if you want to call yourself a photographer, despite the fact that for many they were too over the top.

Marc, regarding batteries. All have a mAh rating so, on paper, all batteries with the same power rating should perform equally when subjected to the same drain on them. All is not equal, though, when it comes to comparing a dslr and a mirror- less camera. The mirror-less is effectively always in live preview mode, either by an EVF or screen. The dslr doesn't draw any power for viewing and this results in significantly less drain on the battery.

Shades of Alfred Hitchcock's "Rear Window"?

"EU General Data Protection Regulation 2018". I did notice that this begins with "EU" so what has it to do with Brexit? And how did this segue from Hitchcock's film to Brexit?

AshMills: I wonder if any crimes were caught on camera.. I notice someone has blurred all the license plates- can that be done automatically?

google street view does it, and given the number of cars they must capture when their vans are out and about, I'm guessing number plate removal is not done by hand.

You've been reading too much fake news about the English weather. :D) We do get rainless days from time to time. This is why I always have a fully charged battery at the ready.

It's London, day and night. I've seen that before. So what's new here? Are we impressed at its gigapixel size? Again, yawnnn. Who is going to actually look at this? Maybe it's of some use as advertising for the virtual reality sponsor, but come on. Art? A machine made it. Compelling? No.

"A machine made it." Hmm, that means every image you've ever captured.

Accepting that this is a Nikon-centric post, on the general question of using this type of adapter it must be accepted that they are not as efficient in AF performance as a native lens, but having said this, if one's shooting needs don't rely on fast AF, they do allow for lenses other than Sony's native line-up to be successfully used.

Since I bought my A7 upon its release I've only used three AF FF lenses, two Canon, the 50mm f1.8 Mk1 and 28-105 USM (Japanese made version) and a Tokina 20-35mm, using a Viltrox AF adapter. I find the AF speed with the zooms slowish, that's to say not too slow, but when the A7 focus locks it is always spot on. But my photography style is leisurely, so the AF speed doesn't matter. Accuracy in focus does. Sadly, the 50mm isn't compatible and won't AF, but I do get electronic aperture control, so whilst I have to manually focus, without having to use the "shoot without lens" setting, auto exposure still works with open aperture metering.

dannyboy5400: For people who keep saying that you shouldn't put a Nikon lenses on a Sony or keep native lenses, I say you are not looking at the bigger picture.
1. No mirror slap with the Sony body, that is a big deal.
2. Sony has a non existent selection of lenses 2.8 and more than 200mm.
3. Sony lenses are ridiculously priced compared to Nikon and Canon counterparts.
4. More used lenses for Canon and Nikon compared to Sony.

@AlexLex. +1.

People can be very selective when presenting so-called "facts". It usually betrays itself as anti-this or anti-that bias, depending upon what "fact" they wish to portray.

sh10453: Silent for such a long time, and this is all they can muster???
They could have remained with dignity by staying silent & enjoying retirement.

@BJL. Not really surprised that DPR does not make it clear. Their staff don't give me the impression that they are very knowledgeable when it comes to older analogue technology. Perhaps they should hire pensioners who lived through that era. :p)

And to quote "You will be amazed by the wide range of apertures from f/5.6 to f/22". What's amazing about this? Except when you look closer and see it jumps from f8 to f16, missing out f11. Now this is amazing, but in a bad sense.
