On Sony Cyber-shot DSC-RX100 III First Impressions Review preview (2979 comments in total)

Judging from these samples, it's really quite impressive how far we've come in the past 10-20 years of digital cameras. This level of imaging fits in your pocket, with a lens that covers a very useful range, and has a viewfinder.

I had an RX100 Mrk I, loved the pocketability and just about everything else, only complaints were the somewhat detached shooting experience and the corners at wide angle - but this new lens is noticeably better at wide angle, and I think the EVF will go a long way when it comes to an improved shooting experience. Wish the battery life was projected to be a bit better, but I might just pick one up anyways.

In reply to:

Kevin Purcell: One other thing to note: they let the lens distortion go wild to get this lens to folde up.

These lens designs have 7% distortion at the edge of frame at the wide end of the lens. That's a lot of distortion and needs a lot of correction (it's all barrel so it's correctable).

As someone pointed out below the "28mm eq" image in JPEG shows a 25 (or perhaps 26mm eq) lens in RAW.

Indeed. It's also quite likely that corners at wide angle will be noticeably soft regardless of aperture used, as software correction of barrel distortion chews up a fair bit of resolution. This was also the case with the original RX100 - source: I had one for the better part of a year, sold it because of soft corners at wide angle (other than that and a few minor performance/ergonomic hiccups, it was about as good as I could have hoped).

If you want great corner to corner IQ @ wide angle in a pocketable form factor, I recommend taking a close look at the Ricoh GR-V/Nikon Coolpix A.

In reply to:

BorisK1: The table says 26mm equivalent FL, while the text says 28mm. That's a pretty big difference in WA coverage.

Going by 1" sensor 2.72 crop factor, 9.58mm * 2.72 = 26.0mm. That's what I'm rooting for, then :)

Something to consider: the RX100/RX100II uncorrected RAW files have a diagonal field of view similar to 25mm on full-frame, but after correcting for distortion diagonal field of view is roughly equivalent to 28mm.

On Hands on with the Pentax 645Z article (648 comments in total)
In reply to:

Raist3d: If I was a Pro Landscape Photographer, as in selling big prints, etc. of landscapes and having a nice cash flow I would totally go for this.

I tried the first camera before this one and it is quite amazing. Pentax has a long history of medium format 645 film series, and this one supports all those lenses too.

Depends on how big you print and how far you have carry the camera on your back. Specific for landscape use, regardless of price I'd still give an A7r setup consideration due to the size/weight advantage and ability to adapt pretty much any lens (in particular Canon's 17mm/24mm tilt-shifts). A kit based around an A7r could pared down to the 8lb/3.8kg range w/ TS-lens/tripod/filters/etc., vs. likely close to twice that for a medium format setup. If you're doing significant time on the trail to get your shots - ie, multiple nights in the backcountry, where you have to carry a shelter, sleeping bag, food, etc., in additional to camera - all those things start to add up, and the more you carry, the slower you go.

Then again, the 645Z looks awesome, makes digital medium-format more accessible/appealing than ever - the CMOS sensor bodes well for high ISO performance, reasonable frame rate, fancy (by medium format standards) AF system, etc... definitely has quite a bit going for it.

On Chicago-based Calumet Photographic closes U.S. stores article (195 comments in total)
In reply to:

JFMoore: Given my recent experience I am not as sympathetic as I could be. At the Oakbrook store 5-10 years ago, they had a nice store and generally knowledgeable staff (Wendy was particularly awesome), but recently service had gone to zero. The last straw for me was when I asked to see one of the Fuji mirrorless, any of them, and the manager simply said he couldn't keep them in stock and went on a tirade about how they have no demo units and he's been in this business for 30 years and blah blah. Not redirecting me to other products, inquiring about what else I might need, telling me when to come back when they might better have stock, etc. I had $2k ready to burn on something and after venting he basically walked away with an "alright, buddy". He might as well have pointed at the door.

That is not a way to treat a real customer (I have dropped a lot at this particular store, I feel if you get real pro help from people you should give them the sale).

Check out the petapixel interview, sounds like the stock issues were largely a result of the business circling the drain.

In reply to:

straylightrun: Sony e-mount please.

Not sure if troll (three word post makes it hard to tell, and dpreview comments are usually a wasteland anyways), but... if you're actually serious, know that due to the large flange distances this lens was designed for, an E-mount version of the lens would (short of an optical redesign) just be an extended barrel version of the standard lens. Have a look at the Rokinon/Samyang full-frame E-mount lenses compared to the Sony A/Canon EF/Nikon F mount alternatives to see what I'm talking about.


Unless you are concerned about the added flex when using a mount adapter or the additional cost of the adapter, why not just buy the A-mount version and use one of Sony's E to A mount adapters? Overall size would be the same as a native E-mount version, you'd gain access to a larger market for resale, not to mention the ability to use the lens on A-mount bodies (and vice-versa).

In reply to:

AndreaV: Really great shot! Nice composition and beautiful colors!
Pity only for the CA on the left and right trees against the sky. Is it a HDR or composite shot? Which lens did you used?

Given the large amount of CA, this is likely an HDR (CA tends to get accentuated for HDRs in post if you do not make specific efforts to reduce or eliminate it). I suspect the lens was a zoom shot using the widest available focal length (perhaps the 24-85mm f/3.5-f/4.5 VR that is included in the D600 kit?).

In reply to:

Jogger: why dont they just make a universal head for cellphones with the standard tripod screw.. they could pack it in with the normal version

+1 for the griptight, that thing is brilliant for phones. As for Joby's gorillapods (the ones with the articulating sections), eh, not really a fan of those - so many moving parts, the design of those things just looks inherently unstable, and they are pretty bulky considering the weight limits on most of them.

I use the griptight with one of their micro 250 tripods (which is rigid and compact) to watch videos/movies on my HTC One while travelling - the combo is great for media consumption and extremely portable (the griptight mount and the micro 250 fold down to about the size of a pocketknife). You can also remove the griptight section from the micro 250 tripod and use the tripod with a compact camera (it's stable enough for my RX100 and EOS M w/ 22mm f/2 lens), or want to mount the griptight to a different tripod.

Sure, the extreme corners aren't perfect, but still, within the context of camera phones, the results are pretty darn impressive.

Can we get some IQ tests of the camera with the wide angle adapter in place? Because a 21mm (35mm equivalent FOV) wide angle in this small of a package sounds pretty awesome...

In reply to:

Just a Photographer: "Stu wrote about my comment on Lightroom: It's a lot more than that if you actually use the program every day."

Now my question to Stu are:

So where are my layers in Lightroom Stu?
Where are my channels in Lightroom Stu?
Where are my calculation in Lightroom Stu?
Where are my multiple curves in Lightroom Stu?
Where are my levels in Lightroom Stu?
Where can i find 'apply image' in Lightroom Stu?
Where can I make selections in Lightroom Stu?
How can I select color ranges in Lighrtoom Stu?
How do I apply masks in Lightroom Stu and How do i invert them in LR?

Do I need to go on?
Lightroom is ACR added with some stuff that nobody really needs.
Whats wrong with a smart file structure to find you images back?

LR is greatly overrated by many and especially by Adobe who want us to believe that LR is as powerful as Photoshop, while Lightroom only consist of the ACR editing module.

Therewith LR is practically worthless to the main community who have no need to have their files in a database.

Having used LR4 briefly, I agree with OP. LR4 is greatly lacking in functionality compared to Photoshop and the database import requirement was a frustrating, time wasting step that caused to immediately regret my purchase, and I all but abandoned the software after a week or so of use (luckily Adobe did gave me a coupon for $400 off PSCS6... so I guess it wasn't all bad).

Processing my images via Bridge/Photoshop feels so much more streamlined to me (does a better job w/ photos stored on my NAS, don't have to deal with reimporting files across multiple computers - I can just access them, not to mention that all the expanded image editing tools are there when I need them: 32-bit HDR tiffs, Photomerge, etc.). LR4 is basically ACR paired with a constricting/inflexible database layer.

In reply to:

Roland Karlsson: But ... but ... but ... I cant see how to aim the camera. Its just a stand, and not a tripod methinks. Or?

It doesn't lock, but is quite stiff. I've used the tripod portion with an RX100 with no issues - it's plenty study for any of the pocketable compacts out there (it's conservatively rated to 250g/9oz). Also, I'm pretty sure that they also make a slightly bigger/beefier version aimed at M4/3's as well.

On Canon Pixma Pro-10 printer review article (20 comments in total)

Regarding the arbitrary fine art paper margin limitations - just use a different program to print. This is exactly what I do with my Pro 9500 Mark II printer (which suffers from the same margin limitations when using Canon's software to print on fine art papers) - I print using Photoshop CS6, which lets you set any margin you'd like regardless of the paper type/color profile you print with. Using this method I can do borderless prints on any paper type, and I suspect you can do the same thing with the Pro-10.

In reply to:

SirSeth: Samples look good, however, small camera + big lenses = not a cool as Canon want's us to believe. Olympus made very small DSLRs with the E-4xx series, but not until they got rid of the mirror could really small lenses be made to match the body sizes. This SL1 will sell really well for those just sticking with a small kit lens, but mirrorless means a much smaller bag for those who want some versatile optics.

Agreed, a few wider-than-40mm EF-S primes would pair very nicely with such a tiny body.

In reply to:

Bamboojled: I just did a corner comparison in RAW to see how sharp the lens is against the other cameras, the Nikon A is the only one that is showing the texture of the wall and clearly defines the checkered target.

It definitely does way better in the corners than my RX100 at equivalent focal length (that's my only real disappointment from the RX100 - even stopped down, the corners can never be considered great). The JPEG engine in the A also seems to do a decent job at reducing moire while retaining a high level of detail - but the moire in those RAWs would probably drive me nuts from time to time.
