Hi, By the way it is f4.0-5.6 and yes it is a very good lens.

On article Canon EOS R review (3322 comments in total)

HI DPR editors, Thank you for updating your EOS R review with the latest firmware.

I am a bit puzzled by some of your 'What we don't" (like) comments in the summary.
*Quirky questionable ergonomics: Maybe more specific terms would be more helpful for prospective buyers.
* Very difficult to follow moving subjects while shooting bursts: I have been shooting dogs running and birds in flight with no problem following the subject.
* DPAF unreliable in video: I tested this and found no problems
* Evaluative metering may vary greatly from one shot to the next...: Problem not encountered by me.
* AF struggles in back lit scenarios: I have not encountered this either.
* Unimpressive burst shooting speeds: I am getting 5-6 fps with AF, AE and live view on each frame. I find that in fact 5-6 fps works well for many moving subjects.
* Video output generally soft: FHD 25p All-I video (PAL) looks pretty clear and sharp to me and certainly good enough for vlogging.

On article DPReview TV: Why waveforms are better than histograms (333 comments in total)

HIstogram, zebras, blinkies and waveform.
I find the zebras in Panasonic cameras much more useful than the histogram as a guide to possible highlight clipping, particularly as the level can be set by the user.
But for me the most useful of all for still photos is an EVF (and Monitor) preview which accurately predicts the appearance of the final image (RAW and JPG would have different algorithms). This would make the "helper" displays largely un-necessary.

The Mk2 appears to have the same problem with focusing as the original. Both my copies of the original were prone to missing focus when presented with multiple specular light sources. This issue can also affect other cameras which use contrast detect AF. See numbers 25, 26 and 28 in this gallery.

HI Richard, Mirrorless cameras can potentially do two things which DSLRs cannot (not while using the viewfinder anyway) :
1. Provide real time live view without perceptible blackout
2. Enable silent vibration free operation.
I imagine that one day public places, houses of parliament and the like will require photographers to use silent cameras.
It seems to me therefore that mirrorless is not a niche but the main game and that mirrorless cameras will entirely supplant DSLRs in due course.

On article Beta: try out our new 'light' color scheme (718 comments in total)

I would prefer black on light grey, the same grey as I see when rolling over the text of one of the comments here.
I find the white background just a bit over bright but do prefer dark text on light background.

Good samples, thanks for posting, good selection of subjects. Everything looks OK, sharpness/detail, out of focus rendition, highlight/shadow detail, flare control, high ISO rendition up to 3200. Noise reduction in the JPGs appears to be over enthusiastic as is typical of recent Panasonic cameras such as the LX100.
The lens looks OK. I think the RAWs will be fine.

Mr Tokura correctly identified continuous autofocus and EVF performance as constraints to mirrorless development. But he failed to mention shutter shock which is the bane of mirrorless camera systems right now. The definitive solution to this problem is a sensor which supports global shutter. Does Canon have one of those in the wings ?

Mr Heath has a point but I think he is overstating the case.
Many cameras have an [Auto] Mode on the mode Dial [green icon, iA , whatever]
A novice photographer has only to leave all menu items at default, set the [Auto] Mode and fire away.
The camera mostly makes excellent photographs.
Camera users who want to take more control can step up to the [iA+] or equivalent and when that is mastered try out the P,A,S,M Modes.
It is significant that the two cameras which Mr Heath used to illustrate his point do not have a Mode Dial.

The 20th Century way to provide a range of focal lengths was interchangeable lenses. The 21st Century way is a single zoom lens.
Convergence renders the DSLR vs MILC debate less pressing.
The new debate is about the merits of the Interchangeable Lens Camera (ILC) vs Fixed Lens Camera (FLC) in particular Fixed Zoom Lens Camera (FZLC).
Some of the new FZLCs are so good they challenge the need for any kind of ILC at all for many enthusiast photographers.

On article Canon PowerShot G3 X: What you need to know (576 comments in total)

No built in EVF ???
You have to buy one in addition to the camera.
So it costs considerably more.
Leave it on the camera and it becomes taller than a DSLR and prone to damage. Taking it off the camera every time time it goes back in the carry bag is just a nuisance.
Trying to get accurately framed sharp pictures without camera shake with the camera at full zoom and/or bright light will be an exercise in frustration. I have tried it with other zoom cameras, never again.

The unsharpness with double imaging described in this review sounds as though it might be due to shutter shock. A method of testing to determine if shutter shock is present can be found here..http://cameraergonomics.blogspot.com.au/2013/08/how-to-test-for-shutter-shock.html

Thanks for this, good advice. I Tried it with landscape and it works well. Just two comments
1. The Photomerge screen can be reached via ACR>Tools>Photoshop>Photomerge
2. In the second step, in Ps13(CS6) the sequence is Edit (not File)>Auto Blend Layers.
Very nice article.

On article Buying an ILC (149 comments in total)

Re: MILC disadvantages, Autofocus. Some MILC's have very fast and more importantly, very accurate single shot AF. This applies notably to the latest Panasonic Lumix and Olympus Micro Four Thirds cameras. These also have usefully fast and accurate [about 70% in focus] AF Continuous in good light with subjects moving at a fairly steady rate. I switched from DSLR's to M43 mainly because of the more consistently accurate AF from M43. The reduced size was a bonus.

Timur, Thank you for figuring all this out and for taking the time and trouble to write it down systematically. You must be a very patient and determined person. I bought an X10, figured out about one quarter of the complex interdependencies you have revealed and decided the whole thing was much too complicated for my poor little brain. So away it went on eBay with a big sigh of relief from me. Oh, yes, the X10 has quite a few ergonomic problems too, just to complete the picture.

Curiouser and curiouser. Thank you EagerBeaver and x100x for your observations. When I did my tests, I had the camera set to capture RAW+JPG. It did not occur to me that setting RAW (without JPG) would invoke a completely different set of available options for Image Size, DR and ISO, but that is what happens, as you have observed. In 50 years of using many different cameras, I have never before encountered anything like this.

Hi akula57, My observations were actually about image quality which is the end product of lens, sensor and processor. The Canon lens is one stop slower at each equivalent focal length than the Fuji but has a longer zoom range. It is easy enough to compare them at equivalent angles of view and aperture, which I did. The Canon delivered a little more resolution at all comparable angles of view and apertures. I did not comment on build quality as I have found from experience that is something which declares itself over time and usage. The Canon appears to be made from plastic, on the outside at least, the Fuji some kind of metal. I am one of those people who could not care if the camera was made from compressed coconut fibres, but some people feel differently.

TEBnewyork, thank you for raising the issue of left handers. One might also consider people with arthritis, injuries, long fingernails and other issues with manual control. These things do complicate the designer's task but we are not yet at the stage of having modular cameras which can be tailored to each person's individual preference. One day perhaps.
