On Sony rides wave of US Mirrorless sales surge article (732 comments in total)
In reply to:

Timbukto: I have been busy with work, but sorry DPReview staff, the paraphrasing of the PR is misleading at best, but really from a financial reporting point of view an absolute butchering. The PR states 66% increase in *SALES* for mirrorless. This can be a WORLD of difference from 66% boost of income!

In addition an increase of 16.5% in mirrorless with a decline of 15% in DSLR is not in any way a *SURGE*. Again it requires someone with some financial acumen. Lets say DSLR's sold about 1 million units during a shopping season month last year, and mirrorless sold about 250k. A decline of 15% in DSLRs is pretty horrific, but an increase of 16.5% in MILC is pretty measly as well and indicates still the overall *weakness* of the entire market. I am in no way a CPA or hedge fund manager, but the paraphrasing should be scrapped...at this point, just say here is the Sony PR release and leave it at that. I think Bythom may give a more fair assessment of this PR, but as it is now, its butchered.

DPR editorial policy with it's use of Press Releases as factual articles appears to perhaps be an attempt to play to the readers. Newspapers have been doing this for years. It's also a good way to play to the choir. Case in point is some anecdotal info pointing to Sony with the A6000 & A7 grabbing market share from m4/3 which has been loosing market share to Fuji here on DPR. If one looks at the numbers, the Mirrorless segment here on DPR is near the median of all ICL camera ownership (per ownership claim). That's far different from some other sites which put Mirrorless ILC cameras at a 10-12 percent level, well below DSLR usage and almost non-existent compared to camera phones. “Articles” like this are feel-goods. A reason to click through.

(Disclaimer – I have three “mirrorless” cameras and yes, I would buy an A7. I just don't need one.)

In reply to:

Randy Veeman: I see different numbers here. Can someone confirm what is correct?
In the article it says Sony mirrorless revenue is up over the past year and DSLR revenue is down. That does not mean unit sales and could be misleading.
Someone said for 2015 (6 months not a full year), DSLR unit sales are growing (or not falling) faster than mirrorless. Maybe that is units shipped though?

So far the most telling number if correct is Sony having an 11% market share. In 2006 Sony predicted a 20% market share by 2011 and Wikipedia says they had a 13% market share in 2008.

Occasionally it might be entertaining to read press releases as simply press releases, not broad statements of selected facts.

I realize this is a minority opinion; but this is an opinion site...

In reply to:

Photoman: Can you hear your profiles dropping Canon & Nikon??? Will you take mirrorless seriously NOW Canon & Nikon. DSLR's are dying and so are your profits...do you want to be another Polaroid or Agfa?!

MILC (m4/3) was introduced with the G1 in 2008 to great fanfare.

The imminent end of the SLR has been predicted on a daily basis for the last seven years.

However, the technology that has now replaced MILC as the next sure thing is the cell phone. Well, it was the cell phone until tablets rolled in... Well it was tablets, now its phablets. Could ICL cellets be on the horizon? ILC wrist watches? (There's small for you.)

And the SLR? Yup. Its days are numbered. Just wait. Next year. They're done. Nothing new here.

Building a front page “news” item mostly based on a press release is a little disingenuous don't you think?

Mirrorless has been out since 2008. If it was the wave of the future, the undertow of cell phones and tablets has probably washed that away. Sony has a hit with the well priced and positioned “Full Frame” A7 line. By all accounts it's a keeper. Good for Sony.

On Sources of noise part two: Electronic Noise article (234 comments in total)

Richard, Rishi,

When you make statements like "most cameras have low upstream read noise" it would be helpful if you cited your source for the statement. And the same goes for every other statement of implied fact. Your sources should be a readily available so that anyone can easily access them.

Otherwise this is just an editorializing opinion piece. If it is intended as an opinion piece, that's fine, but that should be set out at the beginning.

Upstream read noise is a variable value, which can be affected by heat and the software used to interpolate sensor pixels:

"Interpolation works by using known data to estimate values at unknown points."[1]

"Image interpolation works in two directions, and tries to achieve a best approximation of a pixel's color and intensity based on the values at surrounding pixels." [ibid.]

In reply to:

Astrotripper: With this price tag, lets hope that corner performance is at least on the level of their 42.5, which was significantly better than 25 and 17.5 up to f/1.4.

And I want to see some serious sample photos.

Unlikely that a lens wider than the 25 or 17.5 is going to have corners like the 42.5 at f/1.4. Fast wides in all formats suffer vignetting and softness wide open. Even with that in mind the Noktons outperform quite a few pricey pieces of m4/3 glass at f/1.4 and f/2.0 versus f/2.8 and f/3.5.

If it is as good as the 17.5, it will be a great lens.

Well, does Olympus USA seem to think there's still a market? Or maybe Olympus is just hedging their bet?

Kurt_K: I think one thing that isn't often taken into consideration is just how many excellent models are available for peanuts on the used market these days. Surely that must be cutting into new sales to some degree. I would also agree with a previous poster in saying that some of these companies need to focus on fewer models and then push them with more aggressive marketing.

Would agree about the used market. My brand of choice has turned into KEH.

On Using third-party lenses on Sony Cyber-shot a7 / a7R article (503 comments in total)
In reply to:

mapgraphs: In theory, one might assume that an experienced digital camera reviewer would know how to effectively use a manual lens on any digital camera. But perhaps, an opinion piece is sometimes simply a chronicle of the angst of having to learn how to use something that isn't set to iauto?

I don't have the a7 but after reading the experience here, I wouldn't hesitate to put a 5cm Summitar or anything else on it, set everything to manual and go. Sounds like a very capable camera for legacy glass. Once one spends the time required to become familiar with it.

If you had spent the time needed to learn and work with the functionality you wouldn't be asking. Which by the way I know because the cameras I have used legacy glass on operate in much the same fashion as you described.

It isn't about being right or wrong, it's about methodology that works well, or doesn't. You obviously think well of your efforts otherwise you wouldn't be here firing off responses to the collective unwashed.

I would suggest working with the camera for six months on a daily basis limited to one or two lenses, say a nice Ultron 35mm, then come back and write your opinion piece. Just for yourself.

On Olympus PEN E-P5 Review preview (499 comments in total)
In reply to:

zavaell: I have an E-PL2 and E-PL3. I always have IS switched off and have never, ever had blur at any shutter speed that was not attributable to me. In other words at very slow shutter speeds (say, < 1/100) I can expect the possibility of camera shake even if I can usually achieve sharp shots at slower speeds. I find this E-P5 phenomenon puzzling and still not fully explained.

There is an inherent problem with making global statements based on opinion. For example, conjecture about blurry images maybe being caused by "shutter shock" or maybe created because there might be problems with image stabilization not correcting some vertical displacement, some of the time, with some lenses at some shutter speeds by some users is just that: conjecture.

The problem with the conjecture is that it doesn't answer why some users don't seem to have these problems and it doesn't explain for example, why all images taken at 1/160 with a specific lens aren't always blurry. If it's mechanical, the problem is always there. If it's user error, it may not be.

Sometimes reviews are more about someone learning how to use a specific camera than it is about the camera itself. There can be a value in that, but there are caveats, such as found at the bottom of DPR reviews: "Conclusion / Recommendation / Ratings are based on the opinion of the reviewer"

In reply to:

pdelux: I think there needs to be clarified the difference between shutter shock and camera shake.
- the act of Pressing the shutter button causing vibrations through the camera is more like camera shake, as the camera is now moving. More likely with smaller/lighter bodies. This is what DPR is talking about and it is reasonable to expect the IS system should be able to compensate for such movements. Tripods and other methods can compensate as well.

- shutter shock, on the other hand is demonstrable even on a tripod, and and only involves the sensor moving due to vibrations caused butt the curtain opening and closing. Shutter shock is not an IS issue, though the IS may make it worse, or may not compensate for it enough. The root issue is the curtain.
Turn on Anti SHOCK which introduces a small delay should work around this issue.

I suspect part of the clue is that not everyone experiences "shutter shock" at certain shutter speeds. And the effect apparently is heavily dependent on lens used.

Light weight cameras with light weight lenses demand a deliberate shooting technique. Vibration from a shutter closing and opening sequence apparently only compounds poor technique. This is something that has been discussed quite a bit. And will probably continue to be.

In reply to:

Mirrorless Crusader: DPR why are you giving almost every half-decent camera a gold star now? Literally a large a majority of $600+ cameras now are getting gold stars, it completely dilutes the rating system and makes it look like you are just using it as a marketing ploy to sell cameras at Gear Shop. Can't you come up with a system where only a few cameras at most each year get the top award? Then we would actually know which you really think are best, because right now it looks like you're just trying to satisfy everybody and as a result satisfying nobody.

All that glitters...

Then there's the Previews that never seem to make it to completion...

In reply to:

photohounds: People who flaccidly try to equate amount of materials used in a lens to its price, are the same "thinkers" who think a Ferrrari should cost the same as an-150 truck.
After all the F-150 has MORE materials in it - so it is "better", right?

FACT is, the smaller you make something excellent, the MORE it costs (almost universally).

The f 0.95 DOF tirade is also getting stale (well it was a year ago).
I shot a theatre production this week, no DOF "issues" as imagined by pixel-peeping Bricks 'n' bazookas fans - none at all ...

To judge pictures instead of uninformed opinion:

At the link, select "performing arts", and "footloose", basically unprocessed except for density and a little NR ands I turn the camera NR off (better when there is smoke in the image).

Or here ...
