Peter von Reichenberg: Well...one would excpect little more, right? Especially from Leica with its price tag and reputation. OK, let's see if reddotted fanclub will buy enough of them. Instead of being a trendsetter Leica just hardly tries to compete to Sony...disappointing. On the other hand - whatta shame for CaNikon losing a chance to bring second full frame mirrorless after Sony. I don't see anything special in these pictures many other cameras can't do. For me the biggest WOW goes to Fuji GFX 50S.

Richard,

What's unfair about the comment? Leica is charging, as usual, many times the cost of cameras that can do more/better and in your own words it boils down to an unusual interface with good specs. It only compares well to other Leica's which are often well behind the rest of the industry in all but the claims of of mythical image quality.

marike6: Review is much too short for a Leica camera, and the snarky "Conclusion" section, the bit about "if you have your heart set on a camera with a red dot on it" is kind of obnoxious.

Actually it seems a completely rational analysis of the often irrational reason for buying a camera with a red dot - simply because it has a red dot. As the article points out, it doesn't really do anything distinctly better than other cameras. Why should it be given some special reverence and afforded a review length befitting a Leica? Just the comment conveys a certain conceit for Leica. The deference paid to Leica is often baffling especially when they produce products that aren't even on par. It's refreshing to see a Leica reviewed on its merits alone.

It doesn't appear that Leica is leading the field in any particular way with this camera? I'm sure it's a very nice camera albeit wildly overpriced. If you simply must have a camera with a red dot though that doesn't really matter does it.

SRT201: This is just supposition on my part, but I think part of this may be due to the notion that charge time should be a selling feature for phones, tablets, etc.

First, it's important to understand that Lithium batteries are subject to a phenomena called "thermal runaway". Simply put, once the battery reaches a critical temperature it will continue on the path to it's destruction. In order to stop Lithium cells from reaching thermal runaway, their chemistry is tamed and you end up with Lithium Ion or Lithium Polymer batteries. These batteries have reduced energy density, but they are safer.

I would agree, residual heating would be very unlikely as a culprit.

I just spent time on the charging issue because that is a scenario where the battery is purposely pushed closer to critical limits. You can also push your battery by simply running CPU hungry apps like games that heat up the main CPU cores and the GPU thus pulling heavier current loads through the battery and heating it up in an environment that is now already heated up due to the chipset activity.

Yes, these are my opinions, but skepticism and concern over some of these new techniques is shared by others.

I can tell you that after witnessing just how hot my new HTC phone got with it's "Quick Charge" charger I decided to NEVER AGAIN use the factory charger. I went back to a good quality 5V, 2A charger that charges the battery in a reasonable time and at a much cooler temperature.

Did pushed battery chemistry or fast charge rates have anything to do with the Note 7 disaster? Only Samsung can say. I'm just using my EE background to form a hypothesis. Regardless, I can tell you that I do not and will not use the new fast charge systems on my devices. I want them to charge safely and I want maximum battery life-span out of them.

One last point, taking this and other events into account my advice is to NEVER EVER leave a lithium battery charging unattended.

Runtime AND charge time are now selling points so the device OEM's are constantly trying to balance energy density and charge time. There are a couple possible problems here. In order to increase energy density and thus runtime, the battery design may specify a battery chemistry that is not as stable so even multiple vendors can still be a problem. Now combine that with the ever-impatient consumer (idiot) who wants their gizmos to charge in 15 seconds. New fast-charging technologies are in use that ramp charging voltage beyond the standard USB spec. 5V during the charge cycle in order to rapidly recharge the cells. Some of these system are ramping charge voltage up to 20V! Never mind the fact that this gets the battery closer to it's critical temperature during charging or that this extra heat will decrease battery life-span. The consumer wants something and the marketeers are happy to force the stupid design requirement on the engineering staff.

Sounds nice, however the SNR of the affected image sections is already heavily degraded, they can only do so much to bring back the image portion that was buried in flare. You would think the camera would have gone through more rigorous testing regarding difficult lighting.

In reply to:

snapa: The ONLY thing I was hoping to see was for Sony to introduce ANY new APS-C E-mount native lenses, or even improved MkII lenses of any kind. Since that did not happen (again), I hope Sigma will fill the need for very high quality 'NATIVE' zoom lenses. Even a new WA (16-20) pancake primes would also be welcome :(

Agreed. My a6000 sits mostly unused as Sony seems to think they are selling luxury cars when pricing their lenses. Their lens prices are really rather obscene. They also seem firmly focused on the full-frame line. I recently picked up the little Sigma 30mm which, even without IS, is an awesome little lens with excellent sharpness and contrast from wide-open. Sony seems to be starving their APS-C line and that is unfortunate.

SRT201: YES, PLEASE Corel... get this right! We seriously need somebody to provide a good path AWAY from the Adobe weasels. ON1 RAW may be another way out of the Adobe gulag.

Good questions. ON1 is supposed to be by the end of the year. Don't know exactly when.

On photo Long Beach National Park, Vancouver Island in the Canada: Pacific Coast challenge (5 comments in total)

Agree with previous comment. It's a wonderful shot that shows 10MP is still more than enough. Don't feel the need to sharpen so heavily to compensate for resolution. It's not needed and is a little obvious even when viewing the full shot. Your composition and exposure blow past any resolution limits. It's very frame-worthy.

barrym1966: APsc camera's are for non professionals and non professionals don't want to manual focus. Samyang fail

Aside from all the professionals who use APSC cameras and enthusiasts who like manual focus your blanket statement is of course perfectly accurate.

On article 2016 Roundups: Fixed Prime Lens Cameras (190 comments in total)

Really DPR? You do a decent job of mentioning the Pro's and Con's except the most important one. How about almost medium-format levels of detail without any of the Bayer filter blurring we have all come to simply accept. A 19.6 megapixel Bayer image isn't even in the same league as a Quattro image. These images truly have to be seen to be believed. Taking landscape shots with the DP2Q and zooming in later is like visiting the place again. The details simply go on for miles because the Foveon sensor has been expertly matched to a truly stellar lens in each Quattro.

Yes, the high ISO performance is poor, the leaf shutter takes getting used to, it's a strange ergonomic design, and yes it requires thought and technique. It's not a "day at the theme park" camera. When used properly though, the results are like nothing else. I wouldn't give mine up and highly recommend the Quattro line to anyone looking for a second camera that does something truly special.

On article Special K? Pentax K-1 Review (2655 comments in total)
In reply to:

Fujica: Great camera, but I doubt this is enough for Pentax to stay in the race.

Sure it will attract lots of Pentax owners that currently shoot APS-C, but is this enough to attract completely new customers to the Pentax brand? For this to happen I am not so sure.

Personally I think they gambled on the wrong horse by opting for a traditional DSLR instead of a less 'proven' mirrorless system. Though with the current rapid development of on sensor phase detection AF. This type of AF now has come very close to that of any high end DSLR system (look at Sony A6300 and in lesser extend the Fujfilm X-Pro2 and forthcoming X-T2.)

Next to that there is also good improvements on EVF's over the last years that can nowadays deal with bright light situations much better then years ago and refresh rates have gone up over 100mhz.

NOT saying the DSLR is a dead horse btw.

But I think that if Pentax had gone MILC with this camera they could have won over more hearts and interest.

Barry, I've long been an avid Pentax user but the truth is, a simple Sony P&S provides a refreshingly confident AF relative to my K5 IIs or any Pentax I have owned for that matter. Again, my Olympus E-M10 simply destroys my Pentax DSLR's when it comes to AF. There's simply no reason for that at this point in camera technology. For unfathomable reasons, Pentax has held tightly to the weakest element of their cameras, the SAFOX AF system.

A smart mirrorless design that kept the lens communication protocols would have allowed Pentax to design a converter like Olympus that uses older lenses with no loss in functionality. That would have been a smart more for transitioning existing users and providing time to develop a new line of lenses. My E-M10 shoots AF Olympus 4/3 glass faster and more accurately than my Pentax gear!

Agreed. I own a number of Pentax bodies, but the AF has always been the disappointing element of being a Pentax user. I doubt SAFOX 12 is much better. The AF has never been close to Nikon or Canon and any honest Pentax user knows it. Constant reviewing was the only way to deal with the AF.

IF they had gone with a midrange mirrorless APSC with on-chip AF and completely discarded the aging SAFOX system I think it would have been a win for bringing new users to the brand. Unfortunately the K-01 (which I have and like) was saddled with a terrible aesthetic and the resulting sales probably soured Pentax from pursuing mirrorless. They are now too late to mirrorless game IMO.

In all honesty, a new SAFOX AF system in 2016 is an enigma. It has been obviously subpar for quite some time. Pentax designers should have ditched it LONG ago, but they keep drinking their own Koolaid and iterating little changes to SAFOX. Why? It's a mystery to be sure.

In reply to:

aris14: Three top of their line cams each one aiming in 3 different niche of users. Given what they offer more compared to existing rivals I say that Pentax has a clean advantage overall mainly due its price and specs .

pkosewski,
Agreed Sony menus are utterly tragic. No matter how many times I visit the a6000 menu system it remains an adventure finding things in it. It is truly terrible.

Comparing Pentax to that mess is way off IMO. The Pentax quick menu system and general menu system is well organized but very deep. Pentax provides options you don't often see like being able to fine-tune NR for each ISO level. Indeed that makes for deeper menus.

I think Olympus may have the best menu system personally.

AF is indeed the weak point for Pentax but the K-1 is a considerably more advanced AF system than previous models so I don't know how that compares to Canikon.

In reply to:

gravelhopper: I am a Pentax user myself. I understand users here expressing their high spirits about the K1 and Pentax / Ricoh overall development. But why pitting Pentax against other brands and provocing their followers? We should be better than that. Especially since we see many users of other brands expressing good wishes towards us Pentaxians.

Cheers

Indeed they are which is why I have never gone the Canon or Nikon route and I have used MANY other brands. Still, Pentax is not lily white. You couldn't pay me to own another lens with an SDM motor and Pentax never did take responsibility for those failures.

PEMoriarty: I purchased an original M10 and had terrible battery issues. It went back to Olympus with no good results. Is mine a singular experience? I really liked the camera but eventually had to return it which was an unbelievable pain.

Recently shot for about 4 solid hours at an Air Show with one battery lasting until the final moments of the show. I was pleased with that.
