(unknown member): The improved 100-300mm lens is the most interesting thing in all these releases. If they can get the optical quality up to the point where it matches some of the huge Sigma and Tamron after-market long zooms, it would go a long way toward having a truly high-quality but portable longer zoom lens. For those who don't want to lug a 3-6lb lens around for wildlife. Why mfgs don't sacrifice the short end's performance and concentrate on the long end is beyond me, given how these lenses are used.

I talked to a Panasonic rep at CES, and he confirmed what I've read elsewhere: the 100-300 II is optically identical to its predecessor. However, it has improved autofocus and IS, which means that it should allow for a higher percentage of "keepers." With the 100-300 there have been complaints about the lack of smoothness of the zoom mechanism. I believe this, too, has been improved.

Biowizard: Purchasing Photoshop CS6 both for Windows and my Mac is the last money I'm sending Adobe.


I don't do enough photography, and don't use Photoshop enough to sign up for CC. I use CS6, which meets my needs. However, I keep an eye on new features offered on CC. The only ones that intrigue me are the haze filter and the shake reduction. These are included in PSE14, so I bought it when it was available for $60.
The haze filter is quite good, better than I could do with other filters, but the shake reduction is a disappointment: you have to be very careful if you want to avoid an oversharpened look, and then it doesn't do very much. It turns out that although the name is the same, shake reduction in PSE14 does not have the same controls as in CC. But looking at what you have to do with this filter in CC if you want to avoid oversharpening and artifacts, I don't think I would use it much if I had CC.

SamTruax: All I see here are posts from people who are seriously stuck in the past.
It's a new design, it looks very easy to hold and it will likely take great photos. The price certainly isn't as ridiculous as the $999 they are asking for an RX100 M4 here in Canada.
When the price settles down a little it will probably do well... which is a shame because I would rather it not do well so I can pick one up super cheap when the stores are trying to dump them.

The price of the RX100 Mk.4 in Canada (Henry's) is actually $1,199. They've lost me on this one. The DxO One represents a lot of original thinking, and I expect the IQ to be superb. I'm too used to having a zoom, and too used to a simple ritual of taking the camera out from the belt pouch, turning it on, and taking the picture vs. taking the iPhone from my pocket, turning it on, taking out the DxO One from another pocket (or pouch), connecting the One to the iPhone, and then finally being in a position to take pictures. Similarly, with the iPhone/One combination, putting the camera away is a much more complex operation.

In reply to:

Peiasdf: RX100 / RX100 II is just too much camera in such small size that it renders small mirrorless / EVIL camera like GM1 and Pantax Q pointless. Unless the intent is to use 20 f/1.7 or 17 f/1.8 with the GM1, everyone is better served by a RX.

I have an Rx100 as well and hold it in high regard, but the GM1 is distinctly superior in IQ and flexibility.

This may be the best review that I've read on dpreview: accurately describing the camera's pros and cons, providing enough information for the reader to make a sound decision, and not missing the forest from the trees.

VertigonA380: I really love the specs of this unit, but it's about the size of a small DSLR.....what's that all about?

For me, the change in size/weight from the E-M5 was moving in the wrong direction--and the added features did not make up for it. For less than the price difference trading in my E-M5 on an E-M1, I bought a GM1/12-32. It's a delightful little camera, and has the very useful silent shutter feature that's lacking in OMD cameras.

ThePhilips: To me personally, the new lens - the 12-32 - is much much more interesting. Sadly it doesn't have the built-in lens cap.

There's a Chinese company that makes a self-closing lens cap for the 14-42X. I have one; it works perfectly. I hope that they're coming out with one for the 12-36.

Robert Deutsch: Does anyone know if ACR 7.4 supports the RX100 II? If not, and Adobe forces you to buy into Photoshop CC, I would consider that a major reason not to upgrade from the RX100.

Good news--and bad...

I downloaded RX100 II RAW files from Imaging Resource, and ACR 7.4 (with non-CC CS6) DOES convert these files. That's the good news. The bad news is that, as has been reported elsewhere, at low ISOs the original RX100 produces better results than the RX100 II--and that's with RAW files at default settings. I compared RX100 ISO100 and RX100II ISO160 (the base ISO), and RX100 image was clearly sharper. I then used Smart Sharpen with settings of 0.4 and 70 on the RX100 II converted-from-RAW jpegs, and the converted-from-RAW jpegs from the RX100 was still sharper. It seems that the RX100 sensor is better at high ISOs but not as good at low ones. I don't think I'm willing to make this tradeoff.

I'm sure the next ACR will support it, but I think that will require buying into Photoshop CC, which I don't want. The reason I asked if ACR 7.4 will support the RX100 II is because the RX100 II Raw files have the same designation as for the original RX100.

But I suspect this is just wishful thinking on my part, and the truth is part of Adobe's dastardly strategy forcing people to sign on to CC even if all they want is a version of ACR that will support a new camera. I'll just have to use DxO, which has been very prompt in upgrading to accommodate new cameras.

On article Just posted: Our Canon EF 40mm f/2.8 STM lens review (81 comments in total)
In reply to:

marike6: Canon should update the build quality of the EF 50 1.8 to match this lens. The EF 50 1.8 is a great lens optically, but mechanically it's absurdly non-robust. I'm sure Canon users would be happy to see a metal mount EF 50 1.8, with a bayonet lens hood, and the addition of a stepping motor like the 40 2.8 STM.

I have an original (metal mount) 50/1.8, but I much prefer the 40mm f/2.8--sharper at f/2.8 than the 50mm, and I like the wider angle of the 40mm. With the high-ISO performance of the 6D, having f/1.8 is not that much of a benefit.

Link | Posted on Jun 12, 2013 at 21:26 UTC

Would it be correct to say that for CS6 users there's no advantage in upgrading to ACR 8.1 unless you have a new camera that is not supported by ACR? I realize that the new features are missing, but are there improvemens in existing features? Specifically, does ACR 8.1-for-CS6-users include the improved Smart Sharpen?

jefflins: I'm as upset as everybody else, but the bottom line is simply the pricing model...other concerns only confuse the issue. If it was a dollar a month would you have a problem with the model?

The thing is, if you are a graphics art house and use lots of products, the full suite is a deal at the price of 2 or 3 app subscriptions. Buy 2 get 12 free. The problem is that just one standalone app is too pricy. At 5 bucks a month I'm in. At 10 i'm thinking not. At 20 I'm not even considering it.

Price aside, there are aspects of the legal agreement subscribing to CC that are truly frightening. See

Just a Photographer: WARNING: For those that go LightRoom 5

Remember that LR5 will use ACR 8 - This new version of ACR is NOT supported by CS6. Its the way Adobe tries to suck you into their renting model!!!

From what I've read, ACR6 will be available for CS6, but only the part that allows support of new cameras, not new features like camera shake correction, and (not 100% certain on this) not the improved Smart Sharpen.

W5JCK: From an Adobe blog:

"Q: If you’re going to continue selling Photoshop CS6, will I still get Camera Raw updates?

A: Because Adobe is still selling Photoshop CS6, those customers will continue to receive updated file format compatibility via Adobe Camera Raw 8. When we update ACR8 with new camera support, Photoshop CS6 customers can work with the new version of the Camera Raw plug-in. No new features or functionality will be available in ACR to Photoshop CS6 customers as part of those updates."

So yes we can get ACR updates that work with PS CS6, but they won't contain anything new. WTF! Why give us ACR8 compatibility when it won't do anything for us? We will still have no new cameras added--EVER. What total BS this is!

The fact that new cameras will be supported goes part of the way to placate CS6 users. However, what this statement does not make clear is whether improvements in ACR that are not new tools/features but improvements in existing features (e.g., smart sharpen, which is said to have been improved) will be included in the CS6/ACR upgrades. It they're not, then CS6 users are being left behind even more. The more I think about it, the more this seems like pure blackmail, and a huge PR disaster for Adobe. I unsubscribed from Adobe's email notification about Photoshop, and suggest others do the same.

Link | Posted on May 7, 2013 at 22:01 UTC

It started with ACR: a new version was required to support new cameras, and the new version of ACR required moving to a new version of Photoshop. It looks like Adobe is forcing people to move to the cloud version even if they just want to be able to process RAW files from new cameras and have no interest in the other bells and whistles. This really smacks of blackmail. I am NOT moving to a cloud-based software. I've used PS since series 3, but if Adobe continues on this road, I'll be changing to DxO Optics Pro or some other processing software--even Apple's.

In reply to:

Photato: Without mini lenses is kind of pointless the effort to make it small.
Would have been nice to have a 22mm pancake to go with this, like the EOS-M has.
The only really small lens, the 40mm pancake, doesn't cut it for the EF-S bodies like this one for general photography.

Too bad Canon decided to remain stagnant with the sensor. I was expecting them to start moving towards larger pixels.

What Canon needs is an APS-C equivalent of the Panasonic 14-42X. The fact that they haven't come out with one suggest that there are major technical obstacles to the production of lens of this sort for the APS-C sensor size, and, as you point out, a 40mm pancake just doesn't cut it. And once you put something like a 24-105L IS (or a 100-400L IS!) on the camera, any benefits of a Honey-I-Shrunk-the-Rebel body are moot. The 100D will still sell well, but more for the traditional entry-level DSLR (i.e., Rebel) market rather than the m4/3 market, once people realize that there is little benefit to having a small body if you still have to use big/heavy lenses.

In reply to:

snake_b: I wish DPR did a re-shoot with the EX1, considering that the lens looked decentered in the original review and many complained about that fact. It's not a perfect camera and essentially, Samsung has abandoned it and not fixed weird firmware holes, but it is a good performer.

I've tried most all in the class and in terms of IQ, it absolutely holds its own. The shooting experience is subjective and some of the firmware holes take away from that (no RAW bracketing, remote use during bracketing not allowed, sometimes slow operation, switching to backlit while in RAW results in lockups, so jpeg must be manually selected, and a host of others).

The SRW files are huge (21megs per shot). The hardware is slow. However, the lens is fantastic and so is the swiveling screen.

The first EX1 I got produced images that were sharp in the center, but noticeably softer on the top lef corner than on the top right. I exchanged it; the second sample's images were sharp throughout. I do believe it performs better than the sample DPR reported on. I realize that there's a practical limit to the number of camera samples DPR can be expected to test for a review, but my experience and DPR's experience with the S100 suggests that getting a good sample is something of a crapshoot.

Lee Jay: " every photographer knows, the best camera you own is the one that you have with you."

I really, really hate this expression. The best camera is the one best suited to the job, regardless of whether or not you were too lazy to bring it with you.

I hate that expression, too. It's too simplistic. It would be more correct to say that any camera that you have with you is better than having no camera at all, but that doesn't make it the best camera (or lens) for the purpose.

I have a G3 and will probably buy a 14-42x, but I don't care about the new zoom feature. I set the zoom so as to get the right composition, and knowing exacly what focal lenth I have it set at does not help me in this respec. (If I've reached the wide angle or the tele limit, that will become apparent without a focal length readout.) Similarly, the stepped zoom feature just restricts my options--I want zooming to be continuous. Zoom speed adjustment might be helpful, but it sounds like the default slow-then- fast control is the best compromise. Zoom resume is probably the most potentially useful feature, although this is already the case with the 14-45/14-42 if you're careful not to twist the lens barrel.

Anyway, if I had one of the cameras that did not support all these zoom features with the new lenses, this wouldn't bother me.
